+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+		  GNU LIBRARY GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+ 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL.  It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it.  You can use it for
+your libraries, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library.  If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software.  To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+  Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs.  This
+license, the GNU Library General Public License, applies to certain
+designated libraries.  This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+  The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it.  Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program.  However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+  Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries.  We
+concluded that weaker conditions might promote sharing better.
+
+  However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves.  This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them.  (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.)  The hope is that this
+will lead to faster development of free libraries.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+  Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+		  GNU LIBRARY GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License").  Each licensee is
+addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    c) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    d) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the source code distributed need not include anything that is normally
+distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Library General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+     Appendix: How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Library General Public
+    License as published by the Free Software Foundation; either
+    version 2 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Library General Public License for more details.
+
+    You should have received a copy of the GNU Library General Public
+    License along with this library; if not, write to the Free
+    Software Foundation, Inc., 59 Temple Place - Suite 330, Boston,
+    MA 02111-1307, USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+	can store using const0_rtx (i.e., make all operands to `st' %rx).
+
+	* output-sparc.c (various places): changed dispatches on SYMBOL_REF
+	to dispatches on CONSTANT_ADDRESS_P since we now recognize any CONST
+	(and not just SYMBOL_REFs).  Don't recognize special case CONST for
+	output_block_move.  Compiler doesn't have enough information to use
+	it.
+
+	* stmt.c (expand_fixup): If the control stack is nested within the
+	nesting stack, then no fixup is needed.  Otherwise, compiler must
+	check for possible fixups between the current nesting stack and the
+	nesting stack that immediately contains the control stack.
+
+	* stmt.c (expand_function_start): functions which are nested use
+	DECL_CONTEXT.  For these functions, test that their DECL_CONTEXT is
+	a LET_STMT node.
+
+	* tree.h: declare `build_offset_type'.

+	Don't try to use ldd/std if OP1 is a constant.
+	* sparc.md (movdi): Allow immediate args moved into general regs.
+
+	* c-decl.c (grokparms): Reject incomplete parm types even if just
+	declarating, not defining.  Change types to error_mark_node
+	in both the PARM_DECL and the list of types.
+
+	* dbxout.c (dbxout_type): It's not a bug if a RECORD_TYPE
+	has a typedef as its TYPE_NAME.  That happens in C++.
+
+	* Make each `asm' with operands record its source file/line
+	with reg-notes.  It doesn't work to emit a special note before the insn
+	because the insn can be moved by loop_optimize.
+	* stmt.c (expand_asm_operands): New args FILENAME, LINE.
+	Record them in the insn, in reg notes.
+	* c-typeck.c (c_expand_asm_operands): New args, passed along.

+
+	* reload.c (find_reloads): Don't clear BADOP for a reg letter
+	if the alternative ultimately doesn't allow any regs.
+
+	* reload.c (find_reloads): If an `asm' insn gets an error,
+	change it to a USE to avoid duplicate error msgs or later trouble.
+
+	* reload.c (find_reloads_address): Reloading a constant address,
+	specify Pmode as the mode for push_reloads, in case of CONST_INT.
+
+	* expr.c (emit_push_insn): Fix calc. of space needed when PARTIAL > 0.
+	Both scalar case and BLKmode case needed fixing.
+
+	* sparc.md (load/store constant address):
+	Moving DF from mem to cpu regs, don't go via %f0.
+	Don't use std/ltd if alignment is wrong or uncertain.
+
+Sun Nov 27 10:34:53 1988  Michael Tiemann  (mdt at yahi)
+
+	* reload.c (push_reload): Allow VOIDmode for INMODE, OUTMODE;
+	default the mode from the operand values.
+
+	* sparc.md: remove patterns which generate annulled branch insns.
+	They are correct, but those insns confuse GDB.
+
+	* tm-sparc.h (GO_IF_LEGITIMATE_ADDRESS):
+	Treat any constant address like a SYMBOL_REF.
+	* sparc.md: Check for CONSTANT_ADDRESS_P rather than SYMBOL_REF.
+
+	* sparc.md: Peepholes now accept SYMBOL_REF addresses.
+	The output routine can now split them properly even as delay insns.
+
+	* print-tree.c (dump): added entry for METHOD_TYPE and
+	METHOD_CALL_EXPR.  Also added entry for WITH_CLEANUP_EXPR.  Suggest
+	that we make first_rtl of WITH_CLEANUP_EXPR 2 instead of 1.

+
+	* print-tree.c (dump): added entry for OP_IDENTIFIER.
+
+	* tree.c (build_op_identifier): new function.  Needed because
+	`build_nt' expects an "e" node, but OP_IDENTIFIER is an "x" node.
+
+	* store_layout.c (layout_record): use DECL_FIELD_CONTEXT instead of
+	DECL_CONTEXT.
+
+	* tree.h (DECL_FIELD_CONTEXT): new macro.  Points to the type that a
+	FIELD_DECL is a member of.  For C, this is just DECL_CONTEXT.
+
+	* tree.c (build_method_type): typo used "==" to assign basetype to
+	TYPE_METHOD_BASETYPE with predictably poor results.
+
+Sat Nov 26 22:55:32 1988  Michael Tiemann  (mdt at yahi)
+
+	* output-sparc.c (output_sized_memop): new function to output a load
+	or store insn based on the size of the operand loaded or stored.

+	(gen_scc_insn): new function used by define_expands for
+	set-on-condition-code insns.
+	(output_delay_insn): now knows how to handle load and store

+	  ld/st [%g1+%lo(address)],%reg	-> b target
+	  b	target			-> ld/st [%g1+%lo(address)],%reg

+
+	* tree.c (build_method_type): now corresponds to defn in tree.def
+	  expr.c (expand_call): removed code to get FUNCTION_TYPE from
+	  METHOD_TYPE.  This should probably be looked at harder.
+
+	* tree.def (METHOD_TYPE): Changed definition so that TREE_TYPE (m)
+	(where m is a METHOD_TYPE) is the type of the return value of the
+	method, not the FUNCTION_TYPE from which the METHOD_TYPE is derived.
+	
+	* Makefile: Changed target of BINDIR from /usr/local to
+	/usr/local/bin.

+
+	* expr.c (bcc_gen_fctn, setcc_gen_fctn): new tables,

+
+	* loop.c (move_movables): Never move a reg w/ # > old_max_reg.

+
+Fri Nov 18 13:07:06 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
+
+	* stmt.c (fixup_var_refs_1): (SUBREG (MEM)) was slipping through
+	in case where a SET was writing in the variable being fixed.
+
+	* recog.c (register_operand, nonmemory_operand, memory_operand):
+	Changes to handle new var reload_completed: 1 means that
+	(SUBREG (MEM)) now counts as a mem-ref, since alter_subreg
+	will make it one.

+	set `savings' to 1 initially, since only 1 insn will be moved.
+	And don't let any other reg force that insn.
+	Reduce initial THRESHOLDs.
+	(move_movables): Don't add `consec' into `savings'
+	since the initial `savings' was proportional to `consec'.

+	before writing the output-reload move-insn.
+

+
+	* combine.c (use_crosses_set_p): Moving a ref to stack ptr

+Sat Nov  5 12:46:39 1988  Randall Smith  (randy at sugar-bombs.ai.mit.edu)
+
+	* tm-m68k.h (HARD_REGNO_MODE_OK): Disallowed d7:a0 as an allowable
+	pair of registers to hold a double value.  This is correct for the
+	fpa but incorrect for the 68881.  It was, however, simpler than

+	If minimum is negative, install it in the type and make it signed.
+
+	* stor-layout.c (layout_record): STRUCTURE_SIZE_BOUNDARY is minimum.

+
+	* flow.c (propagate_block): When a dead insn has a REG_RETVAL note,
+	call mark_set_regs anyway, so that `significant' is updated.
+
+	* jump.c (follow_jumps): New arg IGNORE_LOOPS.  If 0, don't follow

+
+	* loop.c (loop_optimize): Mention invalid multiple-entry loops in log.
+
+	* m68k.md (extv, extzv): Fix # of alternatives mismatch in constraints.

+Fri Jun 10 00:25:18 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
+
+	* reload1.c (choose_reload_targets): When writing back an incremented
+	value (handling reload_inc), write back to the real place, not to
+	OLDEQUIV (a register that holds the same value).
+
+	* tm-m68k.h (LEGITIMIZE_ADDRESS): Don't give force_operand a target.
+	This can cause the use of multiple insns with same output reg,
+	which can confuse cse.
+
+	* loop.c (consec_sets_invariant_p):
+	If invariant_p ever returns 2, we return 2.
+	New arg is # of consecutive sets to look for,
+	since this info is no longer in n_times_set at move_movables.
+	(scan_loop): If consec_sets_invariant_p returns 2, set m->cond.
+	(move_movables): check consecutive insns if m->consec && m->cond.

+	even if the parm came in a register; and use that stack space
+	if the parm needs to be addressable or is BLKmode.
+	Rearrange to simplify conditionals.
+
+Thu Jun  9 01:21:29 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
+
+	* local-alloc.c:
+	`qty_...' vectors' elements for hard-reg-numbers now aren't used.
+	`reg_qty' elements for hard-reg numbers now aren't used,
+	and the element for a pseudo is never a hard-reg number.
+	(local_alloc): No need to reset those elements.
+	No need to reset elements out of range of prev block's NEXT_QTY.
+	(reg_is_born, reg_is_set, wipe_dead_reg):

+	(reg_is_born, wipe_dead_regs): Block-number arg no longer needed.
+
+	* local-alloc.c (combine_regs): Remove old code for tying hard regs
+	to pseudos; great simplification results.

+	* reload.c (find_reloads): Use loops instead of bcopy.
+	Check early for insn with no real constraints, and return.
+	Also check for move from hard reg to hard reg and return.
+
+	* cse.c (canon_reg): Rewrite for speed; use a switch.
+	(cse_insn): Don't call find_reg_note if REG_NOTES is 0.
+
+	* cse.c (cse_insn): Store modified SET_SRC even if there's a REG_EQUIV.
+	Inhibition was needed when the SET_SRC was the only place to find the
+	equivalent value; now it is in the REG_EQUIV note.
+
+	* stmt.c (expand_asm_operands): If NINPUTS is 0, make vec of no elts.
+	* regclass.c (reg_scan_mark_refs): Don't lose if XVEC (x,i) is 0.

+
+	* cse.c (cse_insn): Return very early for (set (reg) (call...)).
+	Mainly to save time.
+	(cse-insn) Old code to add REG_WAS_0 note wasted time but did nothing.
+
+	* expr.c (clear_pending_stack_adjust): Really do clear it,
+	if current fcn doesn't want to be inline.
+
+	* cse.c (cse_insn): Speedup: instead of safe_hash, use canon_hash
+	or HASHREG.

+Mon Jun  6 21:47:23 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
+
+	* jump.c (rtx_renumbered_equal_p): Reject ADDR_VEC fast.
+
+	* cse.c (cse_insn): Ignore a REG_EQUIV or REG_EQUAL note if the
+	equivalent value is the same as the SET_SRC of the insn.
+
+	* flow.c (life_analysis): Don't call volatile_refs_p for a CALL_INSN;
+	just assume value is 1.
+	(propagate_block): Don't call mark_{used,set}_regs for a stack-pop
+	since if it isn't dead it has no effect on any useful life data.
+	(mark_set_1): Return quickly if setting stack-ptr, and almost as
+	quickly if setting any hard reg.
+	(mark_used_regs): Likewise for refs.
+	Also don't scan the vector of an ADDR_VEC or ADDR_DIFF_VEC.
+	(volatile_refs_p): Likewise.
+
+	* varasm.c (output_constant): Discard NOP_EXPR and CONVERT_EXPR
+	in integer case (they were for casting a pointer).
+
+	* parse.y (compstmt_or_error): Parse a compstmt after ignoring error.
+	Use this for fctn body so that an error after store_parm_decls
+	won't recover to xdecls and call store_parm_decls again.
+	Typical cause was missing semi at end of last parmdecl.
+
+	* parse.y: Add missing semicolons in actions.
+	(yylex): Don't use yylloc.
+
+Sun Jun  5 16:14:40 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
+
+	* typecheck.c (build_array_ref): Check arg types here, to make
+	error message more accurate (not about "addition").
+
+Thu Jun  2 02:41:40 1988  Richard Stallman  (rms at rice-krispies.ai.mit.edu)
+
+	* cccp.c (collect_expansion): `#' isn't special if -traditional.

+
+	* tree.c (build_real, build_real_from_int_cst): New 1st arg TYPE.
+	* parse.y (yylex): Pass this arg; requires parsing suffixes first.
+	* fold-const.c (fold, combine, fold_convert): Pass this arg.
+	Handling of float binops in `combine' simplified.
+
+	* tm-encore.h (CPP_PREDEFINES): Remove -Dencore since CC lacks it.
+
+	* final.c (output_source_line): Let ASM_OUTPUT_SOURCE_LINE
+	be used for SDB also.
+
+Mon May 30 00:21:15 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)

+	like current_obstack.
+
+	* decl.c (finish_decl): Error in test for zero-size array warning.
+
+	* reload.c (find_equiv_reg): New arg MODE specifies mode in which
+	an equivalent value is needed.  Equivalence must be good in that mode.
+	In addition, notice overlap with multiword register modes.
+	Simplify, knowing that registers have already been renumbered.
+	It was invalidating memory-goals too easily; setting a reg
+	only invalidates memory-goal if its address varies.
+	* reload.c, reload1.c, jump.c: Calls pass the new argument.
+
+	* cccp.c: For correct ANSI, must reject `$' in identifiers.
+	(dollars_in_ident): Variable says whether to allow them.
+	(rescan): Handle `$' as randomchar if that's 0.
+	(main): dollars_in_ident is set to 0 by -$, to 1 by -traditional.
+	(rescan, do_define): Delete former pedantic warnings for `$'.
+	(initialize_char_syntax, initialize_builtins): Inits split to two
+	functions; former is called after options are scanned
+	so `$' is in is_idchar conditionally.
+	* gcc.c: For -ansi, pass -$ to cccp.
+	* toplev.c, flags.h: Define dollars_in_ident.
+	* parse.y (yylex): Treat $ as punctuation unless dollars_in_ident.

+
+	* cccp.c (rescan): Preprocessing numbers can have signs, after `e'.
+
+	* integrate.c (expand_inline_function): Abort, don't return failure,
+	if max_regno is too low.  I believe this can't happen.
+
+	* typecheck.c (build_binary_op_nodefault):
+	For ordered comparisons, no pedantic warning about void *.

+
+	* tree.c (suspend_momentary): Switch to the saveable_obstack
+	for the sake of inline functions.
+
+	* flags.h (enum debugger): New enum for write_symbols.
+	* toplev.c, varasm.c, final.c: Use the enum constants where appro.
+	Add calls to sdbout paralleling the calls to dbxout;
+	put each in the appropriate conditional {SDB,DBX}_DEBUGGING_INFO.
+
+	* toplev.c (main): Delete -noreg option; it's now the default.
+	Make -O an alias for -opt.  Rename -g to -gg.  -g is alias for -G.
+	Accept and ignore -Wtrigraphs.
+	* gcc.c: Simplify the specs.
+
+	* toplev.c (compile_file), tm-*.h:
+	ASM_FILE_START is now a statement, not just a string to be output.
+	Output it *after* determining the real source file name.
+
+	* fold-const.c (fold): Simplify x >= CST to x > CST-1 (CST positive).
+	To simplify this, canonicalize relationals to put constat last.

+	* reload1.c (alter_frame_pointer_addresses): frame pointer can
+	occur by itself, not just inside a PLUS.
+	(reload): Call eliminate_frame_pointer before reload_as_needed.
+	Otherwise the latter can make reload insns that copy the frame ptr
+	to a data reg, but 68k can't copy sp+const to a data reg.
+
+	* decl.c (implicitly_declare): Always save the implicit decl
+	permanently.  Reuse an old one if it exists.
+	* tree.c (resume_temporary_allocation): Used after `end_temporary...'
+	to go back to temporary allocation.
+
+	* stor-layout (layout_{type,decl}): Call variable_size.
+	(variable_size): Turn a size into a SAVE_EXPR and either compute
+	it right away or put it on a list to be computed later.
+	(get_pending_sizes): Return that list and clear it out.
+	* stmt.c (expand_start_function): Tell `variable_size' to compute
+	sizes right away, and compute those saved on the list.

+
+	* gcc.c (main): Don't handle SIGHUP or SIGTERM if shell ignored it.
+
+	* Makefile, gcc.c: Propagate Make var `libdir' to gcc search path.
+
+	* expr.c (expand_expr): a PARM_DECL with no rtl can occur in size of
+	`a' in `foo (a,i) int i; struct {int x[i];} a;', so report an error.
+
+	* flow.c (insn_dead_p): insn that makes stack bigger is never dead.

+	(asm_operands): Do allow this to be empty.
+
+	* reload.c (operands_match_p): Don't let REG and SUBREG match
+	if the reg isn't a hard reg.
+	No longer nec. to check reg_renumber, now that reload
+	substitutes the hard regno.
+
+	* reload1.c (reload): Counting existing spilled groups,
+	check HARD_REGNO_MODE_OK so we don't get fooled by an odd-even pair.
+	Spill entire need for new groups before spilling any solitary regs.
+	Reg already counted against max_nongroups can't become part of a group.
+	(new_spill_reg): Do bookkeeping associated with a new spill-reg.
+	(n_spills): This var is now static, no longer passed as arg
+	within the file.
+
+	(reload_reg_class_lower): Handle all group-reloads before solitaries.
+	(choose_reload_targets): therefore #if 0 the special code for
+	finding solitary registers that aren't suitable for groups.
+	But fix two bugs in it: braino deciding whether a reload
+	is looking for 1 register (not a group).  Use CLASS_MAX_NREGS.
+	Also braino deciding whether a spill reg can be in a group.
+	Did not fix bug that it fails to test HARD_REGNO_MODE_OK,
+	so it might split up an even-odd pair.
+
+	* vax.md: Special patterns for 8 and 16-bit fields, to make
+	move-insns (like the ones for the 68k).
+
+	* tree.c (convert_to_integer): Pass truncation down thru COND_EXPR
+	as through a binary operator.
+
+	* typecheck.c (build_cond_expr): If unpromoted operand types match,

+
+	* fold-const.c (combine): Typo in MIN_EXPR, MAX_EXPR.
+
+	* reload1.c (reload): Was counting insn_groups as total size of groups,
+	not number of groups.
+	A new spilled group counts against group-needs of superclasses.
+
+	* parse.y (parmlist{,_or_identifiers}_1): In error case,
+	return a tree list just as in the other cases.

+	current_args_size broke since emit_call_1 was changed to restore it.
+
+	* combine.c (try_combine): When i1 or i2 auto-incs a reg, don't combine

+
+	* stmt.c (expand_asm_operands): Don't make zero-length vectors.
+
+	* loop.c (scan_loop): After a fcn call, maybe-trap insns can't move.
+	The fcn call might exit and that would prevent the trap.
+
+	* reload1.c (reload): Set reload_first_uid to next uid to be used.
+	* reload.c (find_equiv_reg): Use reload_first_uid to ignore insns
+	that are due to reloading--only if reload_reg_p is not 0 or 1.

+	Don't allow nonexplicit constants in lprd, multiply or truncate insns.
+	Use reg_or_mem_operand for constraint in op1 of divide insns;
+	a constant there causes regclass to screw up.
+	Split alternative constraints on the bit-field insns to avoid
+	out-of-range operands in exts, inss.  Some cases of extraction
+	can be done faster via memory.
+
+	* flow.c (mark_set_1): When adding a REG_DEAD note, inc reg_n_deaths.
+
+	* dbxout.c (dbxout_type_def): Do nothing for {integer,char}_type_node.

+
+	* final.c, symout.c: If not NO_DBX_FORMAT, include stab.h to get the
+	N_... symbols.  Use their default definitions only if they're undef.

+	* expr.c (expand_call) [no PUSH_ROUNDING]: Always set argblock
+	if there are any stack-passed arguments.
+
+	* typecheck.c (build_unary_op): Mark all increment-exprs volatile.
+

+	reg_class_contents.
+
+	* reload1.c (forget_old_reloads): Handle PARALLEL case by recursion.
+	Explicit store into a spilled reg invalidates old reloaded contents;
+	this can occur when we drop through into a basic block whose need was 0
+	(and so whose local pseudos were not spilled).

+
+Wed May 11 00:47:09 1988  Richard Stallman  (rms at corn-chex.ai.mit.edu)
+
+	* stmt.c (assign_parms): DECL_OFFSET should be offset as passed
+	(not including big-endian width-change correction).

+	* typecheck.c (shorten_compare): Set unsignedp[01] right in case
+	where get_narrower makes no change.
+	(build_binary_op_nodefault): Likewise for shortening shifts.
+
+	* stmt.c (expand_end_case): Use type_for_size to get the type
+	to convert the index to, since `int' is wrong if -mshort.
+
+	* decl.c (grokdeclarator): Don't check PARM type for completeness.
+	(grokparms): If fn definition, check all parm types for completeness.
+	(store_parm_decls): Likewise.

+
+	* tm-hp9k320.h: Define STRUCTURE_SIZE_BOUNDARY.

+	* tm-encore.h: New file from Robert Brown.
+
+	* ns32k.md: Use %c in some addr insns.

+
+	* tree.c (get_unwidened): Don't alter a COMPONENT_REF if
+	innerprec equals the precision of the existing type.
+	It was changing pointers to integers.
+
+	* m68k.md (movdi): Put all fpregs in separate constraint alternatives
+	and handicap them so spill reg won't be an fp reg.
+
+	* parse.y (yyerror): Use the arg as part of the error message.
+
+	* decl.c (start_function): Give the RESULT_DECL type int rather
+	than char or short.
+	* typecheck.c (c_expand_return): Convert value from fn's return type
+	to the RESULT_DECL's type.
+
+	* Avoid generating dbx xrefs to enums, since dbx loses on them.

+	structures).
+	(use_variable): Emit USE for regs used in specified rtx.
+
+	* cse.c (fold_cc0): Stack-frame addresses are always nonzero.

+
+	* decl.c (poplevel): Undo previous change with #if 0.
+
+	* stmt.c: `struct nesting' now records the depth on the stack.
+	Each expand_start... must update and record the depth;
+	each expand_end... uses macro POPSTACK to pop.

+	others.  This way the copied LET_STMTs correspond to the copied NOTEs.
+
+	* varasm.c (decode_rtx_const): For SYMBOL_REF, use string address
+	not address of the rtx.  Library fns have only one copy of the name
+	but many copies of the SYMBOL_REF.

+	current_args_size.

+	* expmed.c (expand_shift): In extzv strategy, handle the operand
+	predicates for operands 0, 1 and 3.  (Not needed for 2.)

+
+	* expr.c (emit_call_1): New arg NEXT_ARG_REG describes # regs

+	* tm-spur.h: Define STACK_BOUNDARY instead of ROUND_CALL_BLOCK_SIZE.
+	* tm-m68k.h: Define STACK_BOUNDARY as 16.

+	* expr.c (emit_call_1): Don't change current_args_size.
+	(emit_library_call, expand_call): Always restore current_args_size

+	* config-hp9k3.h: New file.  USG defined here.
+
+	* tm-3b1.h: #undef ASM_OUTPUT_ASCII (a defn came from tm-hp9k320.h).

+
+	* cccp.c (macroexpand): If traditional, don't disable called macro.
+	(macarg1): Was failing to count backslash-newline inside a string

+
+Mon Apr 25 18:46:53 1988  Richard Stallman  (rms at lucky-charms.ai.mit.edu)
+
+	* jump.c (jump_optimize): Don't do April 20 optimization on first

+	in a CONSTRUCTOR are simple constants.
+	(digest_init): A CONSTRUCTOR with non-null type is treated as ordinary
+	expression, not as a braced initializer.
+	Allow init of an array from an array-valued expr; warn if pedantic.

+	(rescan): Digit-case was dropping into the $-case; reorder.
+
+	* cccp.c (rescan): Comment start when -traditional was output as
+	`/*'; should be nothing.

+	don't lose any NOTEs when splicing.
+
+	* flow.c (propagate-block): For CALL_INSN, clobber the call-used regs

+
+	* combine.c (record_dead_and_set_regs): Notice storing in a SUBREG.
+
+	* integrate.c (expand_inline_function): Insn to copy a subroutine's
+	return-value was being output twice, once incorrectly.
+
+	* reload.c (find_equiv_reg): A stack-push insn does not invalidate
+	an equiv for a goal in memory.

+	(PARALLEL case failed to check for this).
+

+	* dbxout.c (dbxout_type): Undo rest of March 29 change:

+

+
+	* typecheck.c (build_binary_op_nodefault): When shortening,

+
+	* tm-vax.h: Turn off continuation on DBX output.

+
+	* rtl.h: LABEL_NUSES was an rtx.  It should be an int.
+	* stmt.c (expand_label, expand_goto): Delete frobbing with LABEL_NUSES;
+	the value stored there was the same as the CODE_LABEL rtx.
+
+	* jump.c (jump_optimize): Detect  if (foo) ...; else { ... break;}
+	and change to  if (! foo) { ... break;} else ...; so can drop out.

+
+	* cccp.c (do_xifdef): Warn about punctuation or other junk in argument.

+
+	* expr.c (preexpand_calls): For RTL_EXPR, do nothing.

+
+	* reload.c (find_reloads_address_1): Always barf if a "constant"

+
+	* local-alloc.c (block_alloc): Make 1 extra slot in regs_live_at.

+	(push_block): Copy SIZE to reg unless it's a reg or constant.
+
+	* expmed.c (expand_divmod): If converting CEIL_DIV to FLOOR_DIV,

+	* integrate.c (expand_inline_function): Don't let inline_target
+	be nonzero in BLKmode.
+

+
+	* genoutput.c (bcopy, bzero): Renamed to mybcopy, mybzero

+
+	* varasm.c (force_const_mem): Fix typo in arg decl.

+Wed Apr  6 14:06:38 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)

+

+
+	* genemit.c (gen_expand): Use emit_jump_insn, emit_label, emit_barrier

+	into inline_target *everywhere* except in or right after a call.
+	* integrate.c (copy_rtx_and_substitute): Delete special case for SET.
+	Replace return-value hard regs with INLINE_TARGET in all contexts.
+	(expand_inline_function): special handling for insn after a CALL_INSN

+	between the CALL_INSN and the value-copy.
+
+	* expr.c (emit_call_1): New name for gen_call_1.
+
+	* Bug: ({...}) insns were in wrong place for a subexpression

+	* expr.c (expand_expr): Handle RTL_EXPR by emitting the sequence.

+
+	* parse.y (yylex): Handle syntax L"..." and L'...'

+	eval the nonconstant arg anyway if it has side effects.
+	(build_conditional_expr): When merging `foo *' with `void *',
+	also allow `const void *'.  Result type has merged set of qualifiers.
+	(qualify_type): Merge qualifiers of two types.
+
+	* decl.c (get_parm_types): Store any tags defined in parmlist
+	into `last_function_parm_types'.
+	(store_parm_decls): Add those tags into the current binding level.
+
+	* parse.y (parmlist, parmlist_or_identifier): Pass 0 to pushlevel;
+	no binding levels in C should be transparent to tags.
+
+	* 3b1 support:
+	* tm-3b1.h: New file.
+
+	* m68k.md: Add HPUX_ASM conditionals for shift-by-24-and-compare.
+	In one of the dbra patterns, a HPUX_ASM conditional was backwards.
+	(movhi) [SGS_3B1]: Define the LI... label as in MIT syntax.
+	(addsi3) [SGS]: Syntax for base-displacement differs from MOTOROLA.
+	(subsi3) [SGS]: likewise.
+	(tablejump) [ASM_OUTPUT_CASE_LABEL]: Use 6, not 2, as displacement.
+	This assumes ASM_OUTPUT_CASE_LABEL on 68k is used for a `swbeg'.
+
+	* final.c (final): Use ASM_OUTPUT_CASE_LABEL (if defined) to output
+	any CODE_LABEL followed by an ADDR_VEC or ADDR_DIFF_VEC.
+	It has 4 args; 4th is the insn which is the ADDR_VEC or ADDR_DIFF_VEC.
+
+	* tm-*.h for 68000 (PRINT_OPERAND_ADDRESS): For unscaled indexing in
+	fetch from a branch table, use L and LI symbols as in the scaled case.

+	* cccp.c: If SCCS_DIRECTIVE, define #sccs as no-op.
+
+	* integrate.c (output_inline_function): Real start of function
+	is FIRST_PARM_INSN, not FIRST_FUNCTION_INSN.
+
+	* tree.c (build_string): String contents must be saveable (for
+	inline fcn).
+
+	* cse.c (cse_insn): Don't forget to set dest_hash_code when dest
+	is a stack slot (and so its address is not being optimized).
+
+	* emit-rtl.c (restore_reg_data_1): reg_rtx_no must be 1+ largest REGNO.
+
+	* m68k.md (non-SImode bit-field insns): Change constraint to "o,d"
+	so a nonoffsetable memref is handled by reloading its address
+	but a register can still be handled.
+
+	* toplev.c (main): Execute OVERRIDE_OPTIONS, if it's defined.

+
+	* expr.c (convert_move): Handle a SUBREG in direct truncation case.
+
+	* cse.c (lookup_for_remove): Don't test machine mode of registers:
+	Storing in (REG:SI 0) invalidates (REG:DF 0).
+
+	* decl.c (pushlevel): New arg, nonzero means this level is for
+	variables only, not for tags.  All calls changed.
+	(lookup_tag): Even if THIS_LEVEL_ONLY, skip variables-only levels.
+	(pushtag): Define it in the first non-variables-only level.
+
+	* dbxout.c (dbxout_type): Undo Mar 29 change, in the DBX_NO_XREFS case.
+	So now each struct or union will contain only nameless cross-refs
+	to any others it uses.  The prior change is still in effect when
+	DBX_NO_XREFS is not defined.
+
+	* Implement variable array bounds for parameters.

+	results of the parmlist.
+	* decl.c (get_parm_types): New function; reverse the current decls,
+	put them in last_function_parms, and return a list of their types.

+
+	* make-cc1.com: New version from Kashtan.
+
+	* integrate.c (expand_inline_function): Always set up an INLINE_TARGET
+	for a function that returns a nonvoid nonBLK value.
+	Since `pushlevel' and `poplevel' are called, must also call
+	`expand_{start,end}_bindings' to make a pair of NOTEs.
+	Let them handle USEs at end of scope of formal parameter copies.
+
+	* integrate.c (expand_inline_function): In a new-style CALL_INSN,

+
+	* *.md: Define a "call_value" insn pattern.
+
+	* tm-m68k.h, tm-vax.h, tm-ns32k.h: (NOTICE_UPDATE_CC):

+	function value hard reg.
+	(wipe_dead_reg): If hard reg, call reg_is_born so that the death

+
+	* combine.c (try_combine): Don't allow a call insn as I1 or I2.
+
+	* loop.c (count_loop_regs_set): Move CALL_INSN into a separate

+	(volatile_refs_p): Any CALL constitutes a volatile ref.

+	treat it like setting a reg whose value will be used.
+
+	* expr.c (gen_call_1): New arg VALREG if nonzero means generate
+	a call_value insn which stores in VALREG.
+	(expand_call): Use `hard_function_value' to make the VALREG arg
+	unless expression has type `void'.
+
+	* expr.c (emit_library_call): New 2nd arg OUTMODE is mode of result.
+	(So can give gen_call_1 the proper value-register.)
+	All callers (here and optabs.c) pass this arg.
+
+	* cse.c (canon_hash): Consider all CALL rtx's volatile.
+
+	** end of change in representation of call insns.

+Mon Mar 28 12:34:46 1988  Richard Stallman  (rms at wheaties.ai.mit.edu)
+
+	* tm-vms.h (TARGET_DEFAULT): Default is PCC alignment.

+	pointers volatile * vs nonvolatile * if -fvolatile specified.
+
+	* decl.c (store_parm_decls): Among the old-style parm decls
+	there can legitiately be other decls!  For example, if a parm
+	is declared `enum {foo, bar} x;', there are decls for `foo' and `bar'.

+	pass all the other decls through into the lexical context.

+
+	* tm-sequent.h (PRINT_OPERAND): Output (MEM (MEM (REG))) properly.

+	properly; output stack-pointer as `tos'.
+
+	* flow.c (find_use_as_address): Reject uses within operand 0

+	* reload.c (find_reloads): `o' in constraint means any memref
+	(except auto-increment) is acceptable with reloading.
+	Braino: Clear BADOP, not BAD.
+
+	* reload.c (push_reloads): Use rtx_equal_p (via macro MATCHES)
+	when considering reuse of an old reload.  Otherwise equal values

+	originally matched may fail to match once reloaded.
+
+	* m68k.md (sign_extract and zero_extract insns):
+	If operand 0 is QI or HImode, don't allow register--only `o'
+	(except in some bftst patterns where bitpos is < 8).

+	* gcc.c: Pass -y* to ld.
+
+	* cse.c (struct hash): New member `equivalence_only'.
+	(insert): Initialize it.
+	(cse_insn): Set it to 1 when src_eqv is inserted.
+	When finding cheapest equivalent of something,
+	skip elts that are marked with `equivalence_only'.
+
+	* decl.c (duplicate_decls): Don't call `layout_type'
+	if the type is `error_mark_node'.
+
+	* decl.c (implicitly_declare): If decl will be file-scope,
+	make sure it's a permanent node, and its associated data too.
+
+Sat Mar 26 15:48:50 1988  Richard Stallman  (rms at wheaties.ai.mit.edu)
+
+	* flow.c (insn_dead_p, mark_used_regs): Storing a reg via a
+	ZERO_EXTRACT or SIGN_EXTRACT is dead if the reg isn't needed afterward.
+
+	* stmt.c (expand_start_function): Set current_function_name
+	to the name of this function.
+	* tm-vms.h (MAYBE_VMS_FUNCTION_PROLOGUE): Use current_function_name.
+
+	* expr.c (expand_increment): A SUBREG in op0 can also a be a copy.
+
+	* ns32k.md: Correct range of args for `adjspb' insn.
+	Use `adjspw' when appropriate.
+	New pattern for `lprd' insn.
+	Change some `const_int' predicates to GET_CODE tests.
+
+	* expr.c (expand_call): Eval function before copying args to hard regs.
+
+	* tree.c (make_node, copy_node): Don't get length of a REAL_CST

+
+	* expmed.c (extract_fixed_bit_field): In memory-word case, abort

+	* tm-ns32k.h: Define STRUCTURE_SIZE_BOUNDARY so they will be aligned.
+	* tm-vax.h: Define STRUCTURE_SIZE_BOUNDARY since Unix CC seems to.
+
+	* tm-vms.h (CPP_PREDEFINES): Predefine __GNU__ and __GNUC__.

+
+Tue Mar 22 15:45:10 1988  Richard Stallman  (rms at wheaties.ai.mit.edu)
+
+	* expr.c (expand_increment): Flush special case for register_operand;

+Sun Mar 20 17:58:00 1988  Richard Stallman  (rms at wheaties.ai.mit.edu)
+
+	* tm-sun*.h: Don't predefine `m68k'; Sun's compiler does not.

+
+	* reload.c (find_reloads): Set up goal_alternative_matches

+	to indicate which of the alternatives this insn matches.
+
+	* typecheck.c (commontype): long int vs unsigned int
+	gives long unsigned, if long and int are the same width.
+
+Thu Mar 17 15:39:45 1988  Richard Stallman  (rms at wheaties.ai.mit.edu)
+
+	* emit-rtl.c, tree.c: include local version of varargs.h.
+
+	* decl.c (start_function): Clear TREE_EXTERNAL and set TREE_STATIC

+
+	* cccp.c (error, warning, error_with_line): No longer print
+	charpos within file; lineno is enough.
+
+Wed Mar 16 16:56:36 1988  Richard Stallman  (rms at wheaties.ai.mit.edu)
+
+	* expmed.c (expand_inc, expand_dec): Handy new subroutines

+	* expmed.c (expand_divmod): Use them instead of gen_{add2,sub2}_insn.

+	* expr.c (emit_move_insn): Return the move insn emitted.
+	Eliminate the code here to move a DImode or DFmode by pieces.

+
+	* regclass.c, stupid.c, local-alloc.c, global-alloc.c:
+	Some vars of type HARD_REG_SET should be `register' only

+	Construct all results in new local variable NEW; then test that
+	and decide whether to return it or the original rtx.
+
+	* cse.c (cse_insn): When SRC_EQV is non-0 but set[0] has been
+	cleared, don't insert SRC_EQV in hash table.
+
+	* All insns emitted by a define_expand become part of the SEQUENCE:
+	* SEQUENCE now contains a vector of insns, not of bodies.
+	* insn-emit.c (add_insn): If `emit_to_sequence' nonzero, add the
+	insn to a separate chain, `sequence_first_insn'.
+	(gen_sequence): Take everything on that chain and make a SEQUENCE.
+	(emit_insn): Handle SEQUENCE differently since elts are now insns.
+	(emit_insn_{before,after}): Handle SEQUENCE.

+Mon Mar 14 12:47:28 1988  Richard Stallman  (rms at wheaties.ai.mit.edu)
+
+	* expr.c (expand_expr): Extend the don't-sign-extend-enums hack
+	to COMPONENT_REF.  (See 3 March.)

+	from frame-pointer when they are different.
+	(expand_inline_function): Handle (RETURN) insns, by creating a
+	return_label which is output after the integrated code.
+
+	* parse.y (yylex): Condition for ignoring `inline' was backwards.
+
+	* flow.c (mark_used_regs): Ignore STRICT_LOW_PART, so that
+	an insn that sets STRICT_LOW_PART (and its source values) may be dead.
+	(propagate_block): Always pass 1 for strict_low_ok to insn_dead_p.
+
+	* optabs.c (emit_unop_insn): Don't make a REG_RETVAL note.

+	is to be put in a pseudoreg, do it here, and make the REG_RETVAL
+	note point after that.
+
+	* expr.c (emit_library_call): Never defer stack-pops.
+	Deletion of the library call by flow.c loses if they are deferred.
+
+	* cse.c (cse_insn): Handling of 68k's zero-extend was broken:
+	it made the actual source and the REG_EQUAL source equivalent.
+	* If dest is a STRICT_LOW_PART, ignore the actual source and use
+	the REG_EQUAL source in its place.  src_eqv's mode may be different
+	from src's, so use proper mode in lookups or inserts for src_eqv.
+	* Don't forget to set src_eqv_elt if src_eqv already has an elt.
+	* On use_related_value for src_eqv, use src_eqv_elt.
+
+	* toplev.c (main_input_filename): Name of file mentioned in first
+	#-line in the input.

+	* parse.y (check_newline): Store main_input_filename.
+
+	* expr.c (move_block_to_reg): New function, copies a MEM:BLK
+	to consecutive registers.
+	(use_regs): New function to emit a USE for each reg in a series.
+	(expand_call): Use the two new functions when a precomputed BLKmode
+	arg is passed entirely in regs.
+	(emit_push_insn): Use move_block_to_reg when PARTIAL > 0.
+	Also, don't subtract USED from SIZE twice.
+	Use plus_constant to add ARGS_SO_FAR so can use indexing on stack ptr.
+
+	* varasm.c (assemble_integer_zero): Use rtx 0, not tree 0,
+	to go with prev change in ASM_OUTPUT_INT.
+
+Sun Mar 13 01:16:17 1988  Richard Stallman  (rms at wheaties.ai.mit.edu)
+
+	* varasm.c (const_hash, compare_constant_1, record_constant_1):
+	Handle NOP_EXPR and CONVERT_EXPR in constant expressions.
+
+	* optabs.c (expand_binop, expand_unop): When widening operands,
+	those with VOIDmode (like CONST_INT) may be left alone.
+
+Sat Mar 12 01:09:24 1988  Richard Stallman  (rms at wheaties.ai.mit.edu)
+
+	* varasm.c (assemble_variable): When making a .comm or .lcomm,

+
+	* tm-vax.h, tm-ns32k.h: Define {INIT_,}CUMULATIVE_ARGS
+	and upgrade FUNCTION_ARGS for new calling convention.
+
+	* gcc.c: If -O, define __OPTIMIZE__.
+	(do_spec_1): %c now scans SIGNED_CHAR_SPEC: define __CHAR_UNSIGNED__
+	when appropriate whether or not it is the default.
+
+Fri Mar 11 16:49:25 1988  Richard Stallman  (rms at wheaties.ai.mit.edu)
+
+	* parse.y: Define YYDEBUG.
+
+	* rtl.c (rtx_unstable_p): New function, same as old rtx_varies_p.
+	* explow.c (stabilize): Use rtx_unstable_p.
+	* rtl.c (rtx_varies_p): Ignore `unchanging' (undoing previous change
+	in this function) because `unchanging' doesn't enable cse to compare
+	the value with any particular constant value.
+	* rtl.c (insn_store_addr_varies_p): Delete, since not used.
+
+	* hard-reg-set.h (COPY_HARD_REG_SET, etc.) non-scalar case:
+	Rename and rearrange temp variables to avoid name conflicts with args.
+
+	* regclass.c (reg_class_record): Don't smash class to GENERAL_REGS
+	and don't exit prematurely, when `r' or `g' is seen.  Must merge
+	GENERAL_REGS with previously determined desired class.
+
+	* expr.c (expand_call) [no PUSH_ROUNDING]: When pushing the arg
+	block, try to reuse some of the pending_stack_adjust.
+
+	* cse.c: qty_const can now hold values (PLUS frame_pointer integer).
+	Effect is that storing into a structure doesn't invalidate
+	mem refs to scalar stack variables via addresses in registers.
+	(insert): Load such values into qty_const, like true constants.
+	(fold_rtx): Ignore qty_const if it isn't really a constant.
+
+	* expr.c (expand_expr) VAR_DECL: Copy DECL_RTL before calling
+	change_address, so it isn't permanently clobbered.
+
+	* stmt.c (fixup_var_refs_1): Make sure the stack slot address
+	is valid by calling fixup_stack_1 each time it is substituted.
+
+	* stmt.c (fixup_stack_1): Return the altered rtx.
+	If it's a MEM in the stack, return a copy of it.
+
+	* stmt.c (fixup_stack_slots): #if 0.
+	* stmt.c (expand_finish_function): Don't call fixup_stack_slots
+	because fixup_stack_1 is called elsewhere when necessary.

+	Calls expand_asm_operands, and handles output operands that
+	the other function cannot handle.
+

+	If not -traditional, warn about them.
+
+Mon Jan 25 02:11:18 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
+
+	* expmed.c ({extract,store}_split_bit_field):
+	Functions {extract,store}_split_reg_bit_field now work for memory
+	also, and therefore are renamed.
+	* ({extract,store}_fixed_bit_field): Call those fns when a field
+	is split across two words.
+	Also, preserve the `volatil' bit on memory refs.
+
+	* output-m68k.c (output_move_double): Handle nonoffsetable mem refs.
+	* m68k.md: Relax constraints on movdi, movdf.
+
+	* decl.c (init_decl_processing): Define `int' and `char' first.
+	Set `sizetype' explicitly.
+
+	* stmt.c (fixup_var_refs_1): May not just return when a SET
+	doesn't have VAR as its src or dest.
+
+	* varasm.c: Don't include c-tree.h.
+
+	* decl.c (build_struct): Split this function into three:
+	`xref_tag', `start_struct' and `finish_struct'.
+	`xref_tag' subsumes `xref_enum'.
+
+	* parse.y (structsp): When parsing `struct foo {...}', define the tag
+	as a cross-ref before parsing the components.  Use the three new fns.
+
+	* regclass.c (regclass): Recognize new-format ASM_OPERANDS insns
+	with `asm_noperands', and scan their operands as usual.
+
+	* cse.c: In numerous functions such as canon_hash, rtx_cost, etc.
+	that do tree-walk on rtx, handle vectors of subexpressions.
+
+	* loop.c (invariant_p): Likewise.
+
+	* jump.c (delete_insn): Two bugs:
+	If insn already deleted, return the first following nondeleted.
+	Deleting a jump's label can delete NEXT.  Make sure return value
+	is always the first insn following INSN and not yet deleted.
+
+Sun Jan 24 02:27:49 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
+
+	* rtl.def (ASM_OPERANDS): Change the rtl expression of an
+	`asm' with operands so it looks like this for one output operand:
+	(set OUTPUT (asm_operands:OUTPUTMODE INSNSTRING OUTPUTCONSTRAINT
+					     0 INPUTS INPUTCONSTRAINTS)).
+	and like this for multiple outputs:
+	(PARALLEL [
+	  (set OUTPUT0 (asm_operands:OUTPUTMODE INSNSTRING OUTPUTCONSTRAINT
+					        0 INPUTS INPUTCONSTRAINTS)).
+	  (set OUTPUT1 (asm_operands:OUTPUTMODE1 INSNSTRING OUTPUTCONSTRAINT1
+					        1 INPUTS INPUTCONSTRAINTS))])
+
+	* parse.y: Change parsing of `asm' to distinguish input and output
+	operands.  Separate them with colon; separate the string with colon.
+
+	* stmt.c (expand_asm_operands): Receive inputs and outputs separately.
+	Generate the new rtl format.
+
+	* recog.c (asm_noperands, decode_asm_operands): New fns
+	for extracting the operands and constraints from these insns.
+
+	* final.c (final): Recognize and output the new rtl format
+	using those new functions.
+
+	* reload.c (find_reloads): Recognize and get constraints
+	from the new rtl format using those new functions.
+	New variable `operand_modes' holds the machine modes of the
+	operands, obtained one way for ASM_OPERANDS insns and another
+	for other insns.
+
+	* rtl.c (note_stores): Calling convention
+	is changed: the first arg FUNCTION now receives as its 2nd arg
+	1 if clobbering, 0 if setting.  Used to be the CLOBBER or SET rtx.
+
+	* local-alloc.c (reg_is_set): This fn is called from note_stores;
+	change its arguments.
+
+	* tm-m68k.h (FIXUP_FRAME_POINTER_ADDRESSES):
+	Use frame_pointer_rtx to recognize intended frame-pointer refs
+	and not recognize pseudo-regs that were allocated to the frame
+	pointer register.
+
+	* emit-rtl.c: All refs to frame pointer use a single rtx, in
+	frame_pointer_rtx.  Likewise arg_pointer_rtx for the arg pointer.
+	If they are the same register, these are the same rtx.
+	Initialize them in init_emit.
+	* rtl.h: Declare these vars.
+
+	* stmt.c (assign_parms, assign_stack_local): Use those rtx's.
+
+Sat Jan 23 00:32:10 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
+
+	* reload.c (find_reloads): Don't combine_reloads if `&' constraint
+	was used.
+
+	* parse.y: Parse `asm' with operands.
+	* stmt.c (expand_asm_params): New fn: generate an ASM_OPERANDS for
+	`asm' with operands.
+	* final.c (final): Output an ASM_OPERANDS insn-body.
+	* regclass.c (regclass): Ignore ASM_OPERANDS, like ASM_INPUT.
+
+	* reload.c (find_reloads): Handle reloading of ASM_OPERANDS.
+	The number of operands can no longer be bounded.
+	For example we can't always put the operands in recog_operands.
+
+	New locals OPERANDS and OPERAND_LOCS point to alloca'd vectors of
+	operands and their locations.  New locals CONSTRAINTS and CONSTRAINTS1
+	hold alloca'd vectors of constraints.
+
+	Unfortunately this isn't enough; every vector with length
+	MAX_RECOG_OPERANDS needs to be dynamically allocated.
+	Would this be too slow?  For now, a cheap "solution" is to delete
+	any insn that has too many operands.
+
+	* rtl.def: Delete VOLATILE, UNCHANGING and UNDESCRIBED.
+	Add ASM_OPERANDS.
+
+	* regclass.c (reg_class_record): Delete ref to UNCHANGING.
+	* loop.c (invariant_p):
+	* rtl.c (rtx_varies_p):
+
+	* cccp.c: Define __VERSION__.
+
+	* decl.c (shadow_tag): TYPE_NAME doesn't work to get the tag-name
+	of a struct, so use new function lookup_tag_reverse.
+	* decl.c (lookup_tag_reverse): Given a type, return its tag name.
+
+	* symout.c (symout_source_file): Output one `struct source'.
+	* symout.c (symout_lines): Output all of them, and the sourcevector.
+	* gdbfiles.h: New file for communication between final.c and symout.c.
+
+	* final.c (output_source_line): New arg WRITE_SYMBOLS says write
+	new GDB-format linenumber info.  Assigns a filenum to each source
+	file name and keeps track of the correspondence.
+
+	* cccp.c (do_include): Output the -M info after searching the dirs;
+	include the actual dir name.  Don't generate "./" for current dir.
+
+Fri Jan 22 04:10:10 1988  Richard Stallman  (rms at frosted-flakes)
+
+	* tm-news800.h: Delete override of INDIRECTABLE_1_ADDRESS.
+	Output is faster if it doesn't use 32-bit displacements.
+
+	* reload.c (combine_reloads): New function.
+	If possible, find an input reload
+	and an output reload that can be turned into one input-output reload.
+	The old output-reload is marked as inoperative: reload_out
+	and reload_in both zero.  This is called from find_reloads.
+
+	* reload1.c (reload, choose_reload_targets): Ignore inoperative
+	reloads.
+
+	* Print warnings for variables that could be clobbered by `longjmp'.
+	* expr.c (expand_call): Generate a NOTE_INSN_SETJMP whenever
+	`setjmp' or `_setjmp' is called.
+	* flow.c (propagate_block): When NOTE_INSN_SETJMP is seen,
+	record the live regs in `regs_live_at_setjmp'.
+	* stmt.c (uninitialized_vars_warning): Warn about vars that have regs
+	that are set more than once and are marked in `regs_live_at_setjmp'.
+	Works through function `regno_clobbered_by_longjmp'.
+	* rtl.h: Define NOTE_INSN_SETJMP.
+
+	* genrecog.c (try_merge_2): When enforce_modes, keep all the
+	alternatives segregated by modes and keep the modes in numerical order.
+	* genrecog.c (write_tree): Make conditions for switch-on-modes
+	know what difference enforce_mode makes.
+
+Thu Jan 21 00:12:35 1988  Richard Stallman  (rms at frosted-flakes)
+
+	* tm-ns32k.h: Use Stein's definitions of PRINT_OPERAND{,_ADDRESS};
+	move the Sequent definitions info tm-sequent.h.
+	Handle %$ in both old and new PRINT_OPERAND.
+	Define CPP_PREDEFINES.
+
+	* ns32k.md: Merge some features from Jan Stein's port:
+	strict_low_part insns, smart output of booleans with small
+	constant args, acbd insns generalized for other increments.
+	Use %$ wherever there is an explicit immediate.
+	Fix shortcomings of adjsp insns: use adjspd in general,
+	and use adjspb in all the cases that allow it.
+	Don't bother explicitly clearing CC_REVERSED.
+	For tstsf/tstdf, output the floating-zero constants
+	using {f,d}const0_rtx.
+
+	A problem still remains, which is that the Sequent and the
+	other ns32k assembler syntax require different 
+
+	* typecheck.c (unary_complex_value): Use correct datatype for
+	compound-exprs.
+
+	* gen*.c (main): Use obstack_init instead of obstack_begin.
+
+	* vax.md: define_peephole for  andl3 x,y,z; extzv z,....,z
+
+	* m68k.md (tstsi): Use cmpw instead of cmpl to test addr reg.
+
+	* tm-m68k.h: Bugs for 68000 when frame size is over 64k.
+	For FUNCTION_PROLOGUE, just subtract from sp instead of fp.
+	For FUNCTION_EPILOGUE, must put the size into a0 and then
+	all insns must be indexed by a0.  And do this even on 68020.
+
+	* tm-isi68.h: Similar changes.
+	* tm-news800.h, tm-hp9k320.h: Similar changes.
+
+Wed Jan 20 04:38:21 1988  Richard Stallman  (rms at frosted-flakes)
+
+	* cccp.c (error_with_line): New function.
+	Use it to report the "unterminated whatever" errors.
+
+	* typecheck.c (build_unary_op): Recursive call had missing arg.
+
+	* m68k.md (movhi): If MOTOROLA, the insn that fetches from a
+	case-dispatch table now defines the LI label as .+2.
+	* tm-news800.el, tm-hp9k320.h (PRINT_OPERAND_ADDRESS):
+	Don't subtract 2 when outputting the address in that insn.
+
+Tue Jan 19 00:02:33 1988  Richard Stallman  (rms at frosted-flakes)
+
+	* cse.c (cse_basic_block): Abort if more qtys were used than allocated.

+	* final.c (output_asm_insn): If %LETTER with no digits,
+	pass null pointer as the operand.
+
+	* output-m68k.c (singlemove_string): Get rid of %e.
+
+	* stmt.c (fixup_memory_subreg): Convert (SUBREG (MEM a)) to (MEM a').
+	* stmt.c (fixup_var_ref_1): Use that fn for operands of
+	SIGN_EXTRACT and ZERO_EXTRACT, since (SUBREG:SI (REG:QI...))
+	could have turned into (SUBREG:SI (MEM:QI...)), which is unsafe.
+
+	* rtl.c (debug_rtx): Print an rtx on stderr, for debugging.
+
+Sun Jan 17 04:37:20 1988  Richard Stallman  (rms at frosted-flakes)
+
+	* gcc.c: options -M* treated like -M.
+
+	* stmt.c (pushcase): Do nothing if the case index has error_mark type.
+
+	* expr.c (expand_increment): Don't use queue for post-inc on memory
+	if the add insn requires register args.  (Better code for RISCs.)
+
+Sat Jan 16 02:10:22 1988  Richard Stallman  (rms at frosted-flakes)
+
+	* ns32k.md: Change register_operand to general_operand.
+	* ns32k.md (udivmoddisi4): Use match_dup where required.
+	Comment it out because it can't accept two independent output args.
+
+Fri Jan 15 00:02:35 1988  Richard Stallman  (rms at frosted-flakes)
+
+	* toplev.c: Include sys/time.h only for BSD.  For USG, use time.h.
+	This is correct for HPUX; don't know about others.
+
+	* gcc.c (execute): Eliminate `union wait'.  Make `status' an int.
+	* gcc.c (execute) [USG]: Use fork instead of vfork.
+
+	* final.c (output_source_line): Use ASM_OUTPUT_SOURCE_{FILENAME,LINE}
+	if they are defined.
+
+	* tm-hp9k320.h: New name for tm-hpux.h.
+	* tm-hp9k320.h (ASM_OUTPUT_LOCAL): Add 3rd arg to `lcomm' statements.
+	* tm-hp9k320.h (ASM_OUTPUT_{DOUBLE,FLOAT}): Use `double' and `float'.
+	* tm-hp9k320.h (CALL_USED_REGISTERS): Don't save any 68881 regs.
+	* tm-hp9k320.h (CPP_PREDEFINES): different names defined.
+	* tm-hp9k320.h (HPUX_ASM, NO_DBX_FORMAT, ASM_SPEC): define these.
+	* tm-hp9k320.h (ASM_OUTPUT_OPCODE): Convert `ftst' to `ftest'.
+	* tm-hp9k320.h: Define ASM_OUTPUT_SOURCE_{FILENAME,LINE}.
+
+	* m68k.md: Rename `hpux' conditionals to `HPUX_ASM'.
+	* m68k.md: Reverse `fcmp' args if HPUX_ASM.
+
+	* cccp.c (print_deps): 2 means give all files, 1 means only user files.
+	* cccp.c (do_include): Support that.
+	* cccp.c (main): -MM sets 1, -M alone sets 2.
+	* cccp.c (main): Give fatal error if I/O error in writing.
+
+	* toplev.c (fatal_io_error): Report I/O error on given filename,
+	and exit.
+
+	* toplev.c (compile_file): Detect error writing asm_out_file.
+	Always put asm file's name in asm_file_name for err msg.
+	* symout.c (symout_finish): Detect error writing symfile.
+	* symout.c (symout_init): Save filename in symfile_name for err msg.
+
+	* gen*.c: Return 1 if ferror (stdout)--in case disk is full.
+
+	* local-alloc.c (block_alloc): Don't crash if 1st rtx
+	in a PARALLEL is not a SET.
+
+	* tm-m68k.h, tm-news800.h (PRINT_OPERAND).  Eliminate code `%e'.
+	* m68k.md: Change `%e' to `e' everywhere.
+	* tm-hpux.h (ASM_OUTPUT_OPCODE): Output `move' as `mov'.
+
+	* tm-m68k.h, tm-news800.h, tm-hpux.h (PRINT_OPERAND):
+	New code `%!' is output as the name for the cc register.
+	* m68k.md (insns that use andi to ccr): Use `%!' to avoid
+	conditionals.
+
+	* cse.c: Record in qty_const_insn the insn that stored the
+	constant value of a qty.  When making a REG_WAS_0 note,
+	store in it the insn that established the value 0.
+
+	* vax.md (movsi): When checking a REG_WAS_0 note,
+	verify that the insn it points to hasn't been deleted or made a NOTE.
+
+Thu Jan 14 00:01:35 1988  Richard Stallman  (rms at frosted-flakes)
+
+	* toplev.c: Eliminate error_with_line and warning_with_line.
+	* parse.y, decl.c: Change remaining calls to those two.
+
+	* tree.c (get_unwidened, get_narrower): To see if a COMPONENT_REF
+	is unsigned, look at the FIELD_DECL, not at the COMPONENT_REF.
+
+	* rtl.c (print_rtx): Print /v for the `volatil' bit.
+	* expr.c (expand_assignment expand_expr): If handling a COMPONENT_REF,
+	note whether it is volatile.
+
+	* fold-const.c (fold): a call to split_tree missed an argument.
+
+	* flow.c (volatile_refs_p): Scan an rtx for volatile mem refs.
+	* flow.c (life_analysis): Record in INSN_VOLATILE which insns
+	have any volatile mem refs.
+	* flow.c (mark_used_regs): Always mark an insn with volatile mem refs.
+	Always pass INSN as an arg.  New arg FINAL now says whether
+	this is the last time scanning.
+	* flow.c (propagate_block): Don't delete insns with volatile mem refs.
+
+	* flow.c: Remove all refs to `obey_regdecls'.
+	Calling this with -noreg just doesn't help -W.
+
+Wed Jan 13 01:13:07 1988  Richard Stallman  (rms at frosted-flakes)
+
+	* decl.c (finish_decl): Error if auto var's size isn't known.
+	Change type to error_mark_node to avoid crash if the var

+
+	* decl.c (build_struct): Reform code to detect erroneous bit-fields.
+	All such errors are now detected here.
+	Promote bit-fields to int if appropriate.
+	If traditional, make all int bit-fields unsigned.
+	Set DECL_ALIGN for members that are not bit-fields.
+
+	* decl.c (grokfield): Don't set DECL_ALIGN here.
+
+	* stor-layout.c (layout_decl): Don't promote the type of a bit-field.
+	Use TREE_PACKED to distinguish a bit-field.
+	Don't check the width because build_struct did that.
+
+	* m68k.md (cmpm): Reject if either operand (address) is a constant.
+
+Tue Jan 12 15:11:20 1988  Richard Stallman  (rms at frosted-flakes)
+
+	* cse.c (canon_reg): Never replace ANY hard reg from reg_rtx
+	because that could alter the machine mode.
+
+	* tm-news800.h: Redefine INDIRECTABLE_1_ADDRESS only if MOTOROLA.
+
+Mon Jan 11 13:15:45 1988  Richard Stallman  (rms at frosted-flakes)
+
+	* jump.c (follow_jumps): If we find a cycle, make it a jump to self.
+
+	* cse.c (predecide_loop_entry): Give up if chase more than 10 jumps.
+
+Sun Jan 10 14:52:42 1988  Richard Stallman  (rms at frosted-flakes)
+
+	* reload1.c (reload): basic_block_needs (new vector) gets 1
+	for each basic block that needs a reload.
+	* reload1.c (spill_hard_reg): Don't spill pseudos that are
+	confined to a basic block which has no need for any reloads.
+	* reload1.c (reload): Each cycle that any element of basic_block_needs
+	changes from 0 to 1, must re-spill all previously spilled regs.
+
+	* regclass.c (record_address_regs):
+	Skip the charging of ICOST if it is 0.
+
+	* flags.h, toplev.c: New flag -fvolatile.
+	* typecheck.c (build_indirect_ref): If flag_volatile,
+	every INDIRECT_REF is marked with TREE_THIS_VOLATILE.
+
+	* fold-const.c (fold): Test in TRUTH_NOT_EXPR case was backward.
+	Also result type is always `int'.
+
+Sat Jan  9 04:16:11 1988  Richard Stallman  (rms at rice-krispies)
+
+	* flags.h (flag_traditional): New flag.
+	* toplev.c: recognize -ftraditional and -traditional.
+	* parse.y (yylex): If flag_traditional, don't recognize
+	`signed', `const' or `volatile'.
+
+	* decl.c (pushdecl): If flag_traditional, any extern decl
+	takes effect at top level.
+
+	* tree.c (lvalue_or_else): New 2nd arg for use in error message.
+	* typecheck.c: All callers pass 2nd arg.
+
+	* global-alloc.c: allocno_preferred_reg can specify a preferred
+	hard reg for each allocno.  If so, try it first (new call to find_reg).
+
+	* global-alloc.c (find_reg): New arg PREFREG specifies reg to try
+	first.
+
+	* decl.c (build_struct): if :0 bit field at the end, round the
+	structure size to multiple of EMPTY_FIELD_BOUNDARY.
+
+	* cse.c (make_regs_eqv): Was testing for reg_next_eqv[lastr] == 0
+	and should be == -1.
+
+	* reload1.c (reload_as_needed): Fix invalid optimization deleting
+	the previous store into a pseudo-reg that feeds an input-reload.
+	It is not safe because a later insn may look in the pseudo's stack
+	slot for the value.  Delete the store only if we can eliminate the
+	pseudo entirely or if the current insn stores a new value there.
+	Also verify that reload_in[j] is a REG.
+
+	* reload1.c (reload_as_needed): When doing an input reload from a
+	pseudo that was stored by the previous insn (not as a reload),
+	redirect the previous insn into the reload register, if this lets
+	us eliminate the pseudo entirely.
+
+	* reload1.c (reload_as_needed): In both of the above cases, it's
+	impossible to prevent a stack slot since one was already assigned,
+	so don't alter reg_n_refs.  Instead, set reg_renumber to record
+	that this pseudo did get a hard reg.
+
+	* stmt.c: Set `volatil' in pseudo-regs for the user's variables.
+
+	* jump.c (delete_insn): Do nothing if insn already deleted.
+
+	* tm-sun{2,3}.h: #define STRUCTURE_SIZE_BOUNDARY 2
+	for compatibility with Sun PCC.  Note that 4.3 vax PCC
+	does not want this.
+
+	* fold-const.c: Replace truncate_unsigned with force_fit_type
+	which truncates unsigned types and sign-extends signed types.
+
+	* expr.c (do_jump): emit_queue before outputting the jump insns
+	that use the comparison.
+
+	* stmt.c: Error message for any goto that jumps into a
+	binding contour that restores a stack level.
+
+	TREE_PACKED (label) means label was defined inside
+	such a binding contour that is now exited.  Using such a label
+	is an error.
+
+	TREE_ADDRESSABLE (label) means label was used from a place
+	outside all such binding contours.  If this is 1 when
+	TREE_PACKED is set to 1, it is an error.
+
+	Any other invalid goto must have a fixup.  fixup_gotos detects
+	such invalid gotos.  fixup_gotos takes a second arg, which
+	is the first insn of the contour now being exited.
+
+	* GNU C version 1.17.

+Thu May 10 22:48:31 1990  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* rtl.def (DEFINE_DELAY): Change description to describe annulling.
+
+	* genattr.c (main): Write out definitions for annulling, if present.
+
+	* genattrab.c (expand_delays): Build internal attributes for
+	which insns can be annulled in a delay slot.
+	(gen_delay): Validate number of elements in DEFINE_DELAY list.
+	(write_eligible_delay): Write out routines for validating annulled
+	insns as well as those in normal delay slot.
+	(main): Call write_eligible_delays to output annulling information,
+	if it exists for this machine.
+
+	* out-m68k.c (not_sp_operand): New function.
+	* m68k.md (andsi3): Don't allow sp as ourput to avoid reload
+	inefficiency.
+
+	* calls.c (struct arg_data): Delete field STORED; add fields
+	PASS_ON_STACK and SAVE_AREA.
+	(prepare_call_address): Static chain value can't have QUEUED.
+	(expand_call): Rework to support additional calling sequence options.
+
+	Major changes include:
+	Call FUNCTION_ARG_PASS_BY_REFERENCE to determine whether an 
+	object should be passed by invisible reference.
+	Handle arguments passed both on stack and in a register; this can be
+	used to allow arguments that are hard to compute directly into
+	registers to be passed.
+	Support option (ACCUMULATE_OUTGOING_ARGS) where the largest amount
+	of stack for outgoing arguments is computer and pushed during the
+	function prologue.  Stack space usage is tracked and any location
+	that would need to be reused will be saved and restored.
+	If preallocating arg block, compute address where each arg will be
+	placed and pass it as target to expand_expr.
+
+	Other changes:
+	Use virtual regs to see if structure value address isn't stable.
+	If inlined, return TARGET if TARGET and TEMP are equivalent.
+	UNNAMED_ARGS_IN_REGISTERS is redundant with the NAMED parameter to
+	FUNCTION_ARG and has been deleted.
+	Use virtual_outgoing_stack_rtx instead of FIRST_PARM_CALLER_OFFSET.
+	Use locate_and_pad_parm to compute any needed padding for argument.
+	If REG_PARM_STACK_SPACE is defined, allocate backing stack locations
+	for args passed in registers; these are not included in the length
+	of stack space required unless OUTGOING_REG_PARM_STACK_SPACE is also
+	defined.
+	When precomputing register parameters, can stop computation when we
+	obtain any rtx, not necessarily a register.
+	No longer need code to protect data written below bottom of stack;
+	this is taken care of by preexpanding calls in argument.
+	target_for_arg no longer needed; its function is performed by
+	store_one_arg.
+	Always copy function return result to our target since they cannot
+	possibly be the same.
+	(target_for_arg): No longer used.
+	(store_one_arg): Save and restore in-use argument list location.
+	Support args passed both in register and on stack.
+	No need for explicit code for preallocated area; now pass location
+	as target to expand_expr; only copy if result in different place.
+	Put sequence point after expanding one value.
+
+	* cse.c (struct write_data): Add bit to indicate stack pointer changed.
+	(canon_hash): Allow recording of stack pointer.
+	(cse_insn): Indicate stack pointer invalidated by subroutine calls.
+	Pass stack push and pop operations to note_mem_written.
+	Process stack pointer assignment as normal operation.
+	Finish change of April 7th that excludes ap and fp from being marked
+	as clobbered by calls.  Also exclude sp; if it is clobbered by a
+	call, an explicit CLOBBER will be written.
+	(note_mem_written): Look for adjustment of stack pointer.

+
+	* emit-rtl.c (gen_inline_header_rtx): Add field for outgoing args size.

+	or argument pointer.
+	(init_emit): Start normal pseudos after virtual pseudos.

+	(init_emit_once): Incoming and outgoing static chain can be the same;
+	inlining of nested functions won't need the distinction.
+	Create unique copies of virtual registers.
+
+	* explow.c (memory_address): Don't worry about refs to fp or ap;
+	force_reg knows how to handle them correctly.
+	(fix_lexical_addr): Moved to function.c
+	(adjust_stack, anti_adjust_stack): Do nothing for adjustment of zero.
+	(allocate_dynamic_stack_space): New function copied from
+	expand_builtin.  Handle STACK_POINTER_OFFSET via
+	virtual_stack_dynamic_rtx.  When STACK_POINTER_OFFSET is defined,
+	perform alignment by always reserving a multiple of STACK_BOUNDARY
+	stack bits.  This avoids concern about whether sp itself or the top of
+	stack needs to be aligned; if we start with an aligned stack, we keep
+	it aligned.
+	(round_push): Use ADD and AND rather than DIV and MULT.
+
+	* expr.c (init_expr): Initialize some more vars.
+	(push_block): Use virtual_outgoing_args_rtx so don't need
+	STACK_POINTER_OFFSET here.
+	Merge extra and size more efficiently; no need to call force_operand
+	since memory_address is called.
+	(emit_push_insn): Pass type for FUNCTION_ARG_PADDING.
+	Use REG_PARM_STACK_SPACE instead of FIRST_PARM_CALLER_OFFSET.
+	To see if must copy address, check if it is a virtual register that
+	will be mapped to sp; only need check if not accumulating space
+	space for outgoing parms.
+	Ignore EXTRA if argument block has already been allocated.
+	(emit_library_call): Major rework to support calling sequences similar
+	to expand_call in calls.c, but only support a very small subset of
+	the conventions; abort if something outside our subset occurs.
+	Abort if incorrect mode is passed; we can't convert here since we don't
+	know the signedness.
+	(store_field): Check for virtual registers instead of hard registers
+	when seeing if stable.
+	(safe_from_p): Location in outgoing stack area is known to be safe.
+	(expand_builtin, BUILT_IN_ALLOCA): Use allocate_dynamic_stack_space.
+
+	* expr.h: Define current_function_outgoing_args_size and

+	outgoing args size and arg pointer save area.
+	No longer save or restore invalid_stack_slot.
+	(pop_function_context): Set up variables whose value is constant
+	throughout rtl generation.
+	(get_frame_size): No longer adjust by STARTING_FRAME_OFFSET.
+	(assign_stack_local): Use virtual_stack_vars_rtx instead of fp
+	until virtuals have been instantiated, then use fp.
+	Remove reference to obsolete invalid_stack_slot.
+	Can no longer be called with size == 0.
+	(assign_outer_stack_loc): Use virtual_stack_vars_rtx instead of fp.
+	Remove references to obsolete invalid_stack_slot.
+	Push to obstack of containing function when allocating rtx.
+	(put_var_into_stack): Only switch obstacks around making of
+	queue entry.
+	Replace call to parm_stack_loc with reference to info in proper
+	function.
+	(fixup_stack_1): Handle any virtual register instead of handling
+	just fp.
+	(instantiate_virtual_regs, instantiate_virtual_regs_1): New functions.
+	(use_variable, use_variable_after): Check for virtual register
+	instead of checking against ap and fp.
+	(parm_stack_loc): Function deleted.
+	(assign_parms): No longer need internal_arg_pointer.
+	Accept SECOND_TIME argument that suppresses rtl generation and
+	assignments to DECL_RTL.  Used by integrate.c to recompute vars.
+	Don't use FIRST_PARM_OFFSET here; use virtual_incoming_args_rtx.
+	Replace test for nonstable incoming arg pointer.
+	If structure value address is treated as the first argument, add
+	it into the list of arguments; this means we can have a RESULT_DECL
+	in with the PARM_DECL's.
+	DECL_OFFSET is no longer needed by integrate.c.
+	Handle args passed by invisible reference.
+	Support new macro, SETUP_INCOMING_VARARGS, to save all registers used
+	for args including and beyond those for the current arg.  Used for
+	non-ANSI varargs.
+	Pass locate_and_pad_parm data it needs to handle reg->stack boundary
+	if register parameters have assigned stack space.
+	If we received the function's incoming structure pointer as a
+	normal argument, update DECL_RTL of DECL_RESULT.
+	Round total argument size if required; similarly, always use at
+	least REG_PARM_STACK_SPACE bytes if defined.
+	(locate_and_pad_parm): Do not need PARM.
+	Major rework to do much of the job of aligning and padding stack
+	location.  Now a void function wich is passed pointers to struct 
+	args_size vars that are set to the argument position, size, and
+	initial offset.
+	Accept flag denoting if a parm was passed in a register and also
+	the current function declaration.
+	If register parameters are assigned stack locations and there is a
+	minimum required size for the area assigned to register parameters,
+	pad the stack position when a parameter not assigned to a register
+	is encountered.
+	Remove redundant code in MAX_PARM_BOUNDARY case.
+	(lookup_static_chain): Use virtual_stack_vars_rtx instead of fp.
+	(fix_lexical_addr): Move from explow.c.
+	If referencing variable that lives in the incoming argument area
+	of its parent and a separate ap is required, allocate a save area in
+	the parent for it and use it here.  If no separate ap is require,
+	compute offset between ap and fp.
+	(trampoline_address): No need to push obstacks here.
+	(init_function_start): Initialize new vars; delete obsolete vars.
+	(expand_function_start): Don't need to handle case where incoming
+	structure return address is passed as hidden parameter here; now done
+	completely in assign_parms.
+	(expand_function_end): Save ap if a save area was made for it.
+	Set REG_FUNCTION_VALUE_P when copying address of returned
+	structure.
+	Be consistent in use of FUNCTION_... macros vs. hard_function_value.
+
+	* function.h (outgoing_args_size, arg_pointer_save_area): New fields.
+	(invalid_stack_slot): Obsolete, deleted.
+
+	* integrate.c: Major rework and simplification.
+	Split up vars into two classes.  Those used for expand_inline_function
+	and children are now part of struct inline_remap.  Most of the others
+	are for save_for_inline and its children.
+	(function_cannot_inline_p): The only type of arguments that will
+	cause us to reject inlining are variable-sized arguments; also
+	reject functions that return variable-sized objects.
+	For now, don't inline a nested function.  We'll support this shortly.
+	Use current_function_returns_pcc_struct instead of duplicating test.
+	(save_for_inline): No need to set TREE_VOLATILE for parms.
+	Save outgoing args size in header.
+	Use unique copy of virtual reg rtx's.
+	Handle any required fixups for INSN_LIST forward-references.
+	Don't bother resetting dead static vars when we are done.
+	Need not save current_function_pretend_args_size.
+	(copy_for_inline): First copy all insns, then all REG_NOTES to avoid
+	problems with forward references.
+	(struct inline_remap): Move all previously-static vars used by
+	expand_inline_function and children into this structure.  This avoids
+	potential problems due to recursive calls to expand_inline_function.
+	(expand_inline_function and children): Allocate a struct inline_remap
+	and pass to all children.
+	(expand_inline_function): Rework parameter handling by looking at
+	DECL_RTL and using it to determine what types of mappings need to be
+	done.  Support objects passed by invisible reference.  Put any
+	constant memory addresses into const_equiv_map.  parm_map is no longer
+	used.
+	Likewise for the return value: consult DECL_RTL (DECL_RESULT)).
+	Don't allocate space for called function's frame until referenced.
+	No longer need special handling for insn following CALL.
+	Ignore USE whose argument has REG_FUNCTION_VALUE_P true.
+	Ignore setting function register if we don't have a mapping for it
+	(e.g., we are ignoring the result of the call).
+	Look at new SET_SRC for constant equivalences.  Some new ones may
+	have resulted from constant folding.
+	Pass both new and old rtx to try_constants.
+	Discard NOTE_INSN_DELETED notes.
+	Copy insns first, then REG_NOTES, to avoid problems with forward refs.
+	(copy_parm_decls): Compute new address of parameter using the
+	constant equivalence map, which will contain the remapping of
+	the frame and argument pointer.
+	(copy_decl_tree): Likewise.
+	(copy_rtx_and_substitute): Handle references to frame and argument
+	pointers by allocating a space equal to the size of the frame and
+	incoming arguments, respectively, and setting a pseudo to point to
+	the start of each area.  Set up an equivalence in CONST_EQUIV_MAP
+	between fp or ap and the actual address.  Return the pseudo.
+	Don't need to deal with possibility of (SUBREG (CONST_INT)) since
+	we are only replacing register with other registers here.
+	No longer need to special-case PLUS and MEM;  subst_constants will do
+	this work.
+	Update detection of sets of ap and fp.
+	(try_constants, subst_constants): Accept old and new rtx.  They will
+	be isomorphic, with only register numbers changed.  Use old rtx to
+	look up register in CONST_EQUIV_MAP and new rtx for substitution.
+	Correctly handle SUBREG of CONST_INT and CONST_DOUBLE.
+	Fix typos in handling of PLUS.
+	(access_parm_map, copy_address): Delete functions.
+	(try_fold_cc0): Handle both compare and test.
+	(fold_out_cnst_cc0): Rework to simplify and remove dubious cases.
+	(output_inline_function): Call assign_parms to perform any needed
+	setups.
+	Need not restore pretend arg size (will be computed by assign_parms).
+	Restore outgoing argument size.
+
+	* output.h (current_function_outgoing_args_size): New var.

+
+	* rtlanal.c (rtx_equal_p): Update comment on use of
+	REG_FUNCTION_VALUE_P.

+	will restore ap if needed.
+	(expand_return): Don't use STARTING_FRAME_OFFSET here.
+	(expand_end_bindings): Adjust fp in nonlocal-goto handler.  If needed,
+	reload ap from its save area in the frame; allocate save area if none.
+	(expand_decl): Use new function allocate_dynamic_stack_space.
+
+	* toplev.c (rest_of_compilation): Instantiate virtual registers.
+	Clear rtx_equal_function_value_matters immediately after possibly
+	saving current routine for inlining.
+

+	all constants in some cases where only CONST_INT was allowed.

+
+	* optabs.c (emit_cmp_insn): Not all clauses always succeed,
+	so stop using `else' structure.
+
+	* stmt.c (expand_return): Avoid moving void to void, in cleanups case.
+
+Mon Apr  3 18:04:33 1989  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)

+Sun Apr  2 13:02:26 1989  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
+

+	redeclarations of typedef provided they agree.
+
+	* c-decl.c (start_decl): Do expand_decl on the decl that pushdecl
+	returns.  If there was a prev. decl with a different type,
+	we have changed its type and cleared its old rtl, so it need new rtl.

+Sat Apr  1 00:50:11 1989  Matthew Self  (rms at sugar-bombs.ai.mit.edu)
+
+	* expr.c (convert_move): Modified to use mode classes
+	instead of refering to specific machine modes.
+
+	* expr.c (do_jump): Converted to use CONST0_RTX macro.
+	do_jmp no longer refers to any machine modes directly except
+	for VOIDmode!
+
+	* expr.c (compare, compare1): Modified to use CONST0_RTX
+	macro.  No longer refers to any machine modes directly
+	except VOIDmode and BLKmode!

+
+	* optabs.c (expand_binop, expand_twoval_binop, expand_unop,
+	emit_cmp_insn): Added mode widening which is independent of
+	specific machine modes.  It assumes that we may widen to any
+	higher numbered mode of the same mode class.
+	  NOTE: the checks for VOIDmode ops which were present in
+	QI and HI to SI widening are now present in all widening.
+	I assume this is correct.  Also, widening is now possible
+	from QI to HI.  This may or may not be a good thing....

+	* loop.c (struct iv_class): `init_insn' records what inits the biv.
+	Replaces `init_val_set' flag.
+	(strength_reduce): Update and test `init_insn' instead.
+	Use of a biv between its init and the start of the loop
+	does not preclude its elimination from the loop.
+	Setting a giv is ok for eliminating a biv, even if giv is "ignore",
+	since that just means giv will be combined with another.
+	Handle some DEST_ADDR givs for that purpose.
+	Test for giv-setting before check can_eliminate_biv_p.
+	New error check for replaceable giv whose value needed after loop.
+	(only_reg_use_p): New fn.
+
+	* expr.c (expand_expr): PLUS, MINUS with EXPAND_SUM:
+	Associate even harder.
+
+	* loop.c (strength_reduce): Treat all constant biv init vals like ints.
+
+	* loop.c (strength_reduce): Clear all_reduced when v->ignore is set;
+	the code to check this later didn't always do the job.
+
+	* loop.c (verify_loop): Set loop_continue.
+	(scan_loop): mention its value.
+	* rtl.h: Define NOTE_INSN_LOOP_CONT.
+	* stmt.c (expand_loop_continue_here): Output one.

+
+	* loop.c (loop_optimize, move_movables): when moving a `clr' insn used

+	(ASM_FORMAT_PRIVATE_NAME): Override this.
+	(ASM_IDENTIFY_GCC): Override; output nothing.
+	(FUNCTION_PROLOGUE, FUNCTION_EPILOGUE): Round fsize up to % 4.

+
+	* loop.c (scan_loop): Check each libcall for regs it uses

+	should be done by combine.
+	(compare operator): Eliminate except when a SET_SRC.
+	* tm-m88k.h (OPTIMIZATION_OPTIONS): -fomit-frame-pointer is a

+
+Mon Jan 28 12:52:11 1991  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* tree.h (DECL_VIRTUAL_P): Renamed from TREE_VIRTUAL.
+	(struct tree_common): Eliminate virtual_flag.
+	(struct tree_decl): Add virtual_flag.
+
+	* Makefile.in (enquire.o): Pass -DNO_STDDEF.
+
+	* m68k.md (tablejump): Now have a define_expand that does
+	different things depending on CASE_VECTOR_PC_RELATIVE,
+	and a separate define_insn for each case.
+
+	* function.h (outer_function_chain): Declare the variable.
+
+	* tree.c (debug_obstack): Fix typos.
+	* tree.h (struct tree_common): Fix typo.
+
+	* Makefile.in (GNULIB1_TARGET, GNULIB2_TARGET): Variables deleted.
+	(gnulib): Depend on gnulib1.target and gnulib2.target explicitly.

+	* gcc.c (process_command): Fix typo setting switches[n_switches].arg.
+
+	* loop.c (loop_reg_used_before_p): Check insns before INSN, not after.
+
+	* objc-actions.c (objc_finish): Renamed from lang_finish.
+	* objc-parse.y (program): Call objc_finish at the end.
+
+	* Changes from Matthew Self (mself@next.com):
+
+	* objc-parse.y:	 Since objc-parse.y was so out of date with
+	respect to c-parse.y, I started over with c-parse.y and
+	reintegrated the Objective-C modifications.  Now that
+	Objective-C is working I hope that objc-parse.y will be kept
+	more up to date....  I did not re-integrate the lexer since I
+	don't have gperf working.  I simply cut and pasted what
+	Stallman had in objc-parse.y.  Someone with access to gperf
+	should re-generate this stuff.
+
+	* objc-actions.c (comp_method_with_proto,
+	comp_proto_with_proto):	 Stallman's change to use the
+	functions end_temporary_allocation and
+	resume_temporary_allocation is incorrect, since it always
+	leaves allocation temporary, whether it was before or not. 
+
+	Perhaps the push and pop functions would do the trick....
+
+	* objc-actions.c (get_arg_type_list):  Use new function
+	groktypename_in_parm_context.
+
+	* objc-actions.c (_OBJC_SELECTOR_REFERENCES_decl,
+	_OBJC_SELECTOR_REFERENCES_id):	Removed.
+
+	* objc-actions.c (synth_module_prologue):  Eliminated code to
+	forward declare the selector references array.
+
+	* objc-actions.c (init_objc_symtab):  Eliminated code to
+	initialize "refs" field in objc_symtab structure (which is
+	now vestigial).
+
+	* objc-actions.c (build_selector_translation_table): Rewrote.
+
+	* objc-actions.c (build_selector_reference):  New routine.
+
+	* objc-actions.c (build_message_expr, build_selector_expr):
+	Use new routine.
+
+	* config/tm-next.h (GO_IF_INDEXABLE_BASE):  Don't use pc
+	relative addressing for LABEL_REF's.  Since branch tables are
+	in the const section, we treat LABEL_REF's like SYMBOL_REF's
+	here.  Otherwise invalid addresses were being generated.
+
+	* config/tm-next.h (CASE_VECTOR_PC_RELATIVE, CASE_VECTOR_MODE):
+	Use absolute branch tables rather than relative ones.
+
+	* config/tm-next.h (ASM_OUTPUT_MAIN_SOURCE_FILE_END):  Output
+	an N_SO symbol with no name to mark the end of the module.
+	This is needed to support scattered loading on the NeXT.
+
+	* config/out-next.c (handle_pragma):  Call to xrealloc had wrong args.
+
+	* configure: Entry for NeXT must set out_file to out-next.c.
+
+	* config/out-next.c:  Typo: "flags" -> "flags.h"
+
+	* config/tm-next.h (LIB_SPEC):	Brought up-to-date.  There
+	are probably more changes needed here.
+
+	* c-decl.c (pushdecl_top_level):  New function.	 This was
+	copied from an older version of g++.
+
+	* c-decl.c (init_decl_processing): Make alloca first arg sizetype.
+
+	* c-decl.c (groktypename_in_parm_context): New function.
+
+Mon Jan 28 07:07:01 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* loop.c (loop_reg_used_before_p): Don't use INSN_LUID since INSN
+	might have been made by loop.c for an outer loop.
+
+	* loop.c (move_movables, strength_reduce): Replace register references
+	in REG_NOTES as well as PATTERN.
+
+	* loop.c (strength_reduce): Call maybe_eliminate_biv twice, not 
+	three times.
+	(maybe_eliminate_biv): Don't abort if elimination fails even though
+	we thought it wouldn't.	 This can happen if certain insn patterns 
+	aren't valid.
+	(maybe_eliminate_biv_1): Ensure that we do not change the insn at
+	all if all the required changes can't be done.
+
+Sun Jan 27 21:26:29 1991  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* Makefile.in: Rename config-dir back to config.

+
+Sat Jan 26 17:37:48 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* expr.c (expand_expr, case COND_EXPR): Disable special-case of
+	A ? B : C when B and C are simple.  This is now done better by jump.
+
+Sat Jan 26 13:16:58 1991  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* tree.h (TREE_PRIVATE, TREE_PROTECTED, TREE_VIRTUAL): New macros.
+	(struct tree_common): New flag fields.
+	* dbxout.c (dbxout_type): Get rid of conditional; can always use these.
+
+	* cccp.c (lookup_import): Do return -2 if file found.
+	(main): Handle `.m' suffix like `.S'.
+
+	* configure (m68k/next): Use out-next.c.
+
+	* WORD_SWITCH_TAKES_ARG and SWITCH_TAKES_ARG now give # of args.
+	* gcc.c (struct switchstr): New field `args' replaces `part2'.
+	(process_command): Record all the args a switch has.
+	(give_switch): Pass all the strings in `args'.
+
+	* tree.h (struct tree_common): Normally make `code' an enum tree_code.
+
+	* m68k.md (tablejump): New pattern.
+	(casesi, etc.): Deleted.
+
+	* tree.c (debug_obstack): New function.

+
+	* objc-actions.h (METHOD_ENCODING, CLASS_CATEGORY_LIST): New macros.
+
+	* gcc.c (execute): Make fatal signal message clearer.
+	(default_compilers): For .m file, define __OBJC__,
+	and pass -lang-objc and -gen-decls to cc1.
+
+	* dwarfout.c: Include output.h.
+	(current_function_decl, asm_out_file): Explicit extern decls deleted.
+	(abort, fatal): Explicit extern decls deleted.
+	(NO_RETURN): Definition deleted.
+	(named_labels): Don't declare it.
+	(output_symbol): Don't use it.
+	(MAXPATHLEN): Don't define this.  Don't include sys/param.h.
+	(output_source_file_die): Avoid limit on file name size.

+	(output_symbols_for_block): Adapt to using BLOCK, not LET_STMT.
+
+	* configure: Renamed from `config'.
+	* config: Directory renamed back from config-dir.
+
+Sat Jan 26 1990	 Ron Guilmette (rfg at ncd.com)
+
+	* README.DWARF: updated to reflect changes to dwarfout.c, the
+	inclusion of dwarf.h (and its changes) and the fact that the
+	DWARF support is no longer directly tied to the DG versions of
+	GCC.
+
+	* dwarfout.c: included a patch (provided by Ray Essick) to allow
+	dwarfout.c to properly get a value for MAXPATHLEN even on (old)
+	System V.3 systems.
+
+	* dwarfout.c: added support for long long types (as suggested by
+	Ray Essick).
+
+	* dwarfout.c: added support for the AT_comp_dir attribute.  Also,
+	as part of this change, the name of the compilation directory is
+	no longer placed into in the .sources section.
+
+	* dwarfout.c: added support for the AT_addr_ranges attribute.
+
+	* dwarfout.c: added support for the AT_prototyped attribute.
+
+	* dwarfout.c: added support for the AT_src_info attribute. Also,
+	as part of this change, there is no longer a "special" entry
+	at the start of the .srcinfo section for each compilation unit,
+	and the contents of the "special" final entry in the .srcinfo
+	section have changed (to { -1, -1 }).
+
+	* dwarfout.c: modified to allow additional GNU DWARF extensions
+	to be generated whenever the corresponding extended attribute
+	codes are defined (presumably within a modified dwarf.h file).
+
+	* dwarfout.c: use the section names .srcinfo and .sources rather
+	than .finfo and .files.	 The additional specificity is warranted
+	because the DWARF information may someday include information
+	about object files as well as source files.
+
+	* dwarfout.c: fixed a bug where a type attribute was being generated
+	for functions and function types even when the return type was
+	void.  "Standard" dwarf says that if the return type for a function
+	or function type is void then no type attribute should be generated
+	for the corresponding DIE.
+
+Sat Jan 26 04:22:08 1991  Michael Tiemann  (tiemann at cygnus.com)
+
+	* cplus-lex.c (interface_strcmp): Handle String.String.Map.cc and
+	friends.
+
+	* cplus-typeck.c (build_unary_op): Merge change to generate better
+	code from simple cast expression.
+
+Fri Jan 25 10:06:28 1991  Michael Tiemann  (tiemann at cygnus.com)
+
+	* cplus-decl.c (pushtag): Don't call `pushdecl' if the type's name
+	is anonymous, lest we recurse ad infinitum.
+
+Thu Jan 24 23:56:55 1991  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* optabs.c (expand_binop, expand_unop): Word at a time only for ints.
+
+Thu Jan 24 09:40:37 1991  Tom Wood  (wood at dg-rtp.dg.com)
+
+	* sdbout.c (sdbout_symbol): Apply changes in dbxout.c to deal with
+	SUBREG.	 Don't emit a symbolic definition for variables that can't
+	be represented.
+
+Thu Jan 24 21:18:15 1991  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* config: Conditional for setting $os was backward.
+	Also mention name of make-var file if one exists.
+
+	* out-i386.c: Delete a large piece of accidental insertion.
+
+	* dwarfout.c: Don't include c-tree.h or cplus-tree.h.
+	(INT_TYPE_SIZE, etc.): Define them if not overridden.
+	(fundamental_type_code): Distinguish types by TYPE_PRECISION.
+	But also check for the built-in C type names.
+
+Thu Jan 24 15:23:17 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* gcc.c (default_compilers): Pass all args starting with "O" to 
+	cc1 so that -O2 is passed along.

+Thu Jan 24 13:10:27 1991  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* stmt.c (expand_expr_stmt): Don't warn for any casts to void.

+Wed Jan 23 16:31:27 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* emit-rtl.c (emit_jump_insn_{before,after}): Allow PATTERN to be
+	a SEQUENCE.
+
+	* loop.c (check_dbra_loop): Use emit_jump_insn_before when writing 
+	out compare and jump sequence, not emit_insn_before, to ensure that
+	if we only write one insn  that it is a JUMP_INSN.
+
+	* toplev.c (flag_rerun_cse_after_loop): New: -frerun-cse-after-loop.
+	(rest_of_compilation): Rerun cse after loop if desired.

+	write out the info.
+	(print_single_switch): New function.
+	(print_switch_values): Renamed from print_target_switch_defaults.
+	Now prints out currently enabled -f, -m, and -W switches.  Calls
+	print_single_switch to write out switch and handle long lines.
+
+	* rtl.def (SUBREG): Change rtx class from 'o' to 'x'.
+
+	* cse.c (find_comparison_args): Ignore hash table entry if not valid.

+
+	* config: File renamed from config.gcc.
+	Allow abbreviations for +-options.
+	Allow config HOST TARGET.
+	Support +gas and +nfp as separate options.
+	Rename all the machine alternatives to general scheme:

+
+	* Makefile.in (install-dir): Create bindir here.
+
+	* cccp.c (main): Delete duplicat p++ left in last change.
+
+	* Makefile.in (GNULIB1, GNULIB1_TARGET): Renamed from GNULIB*.
+	(gnulib1.portable, gnulib1.target): Renamed from gnulib.*.
+	They now make a file named gnulib1, from gnulib1.c.
+	(LIB1FUNCS, LIB1FUNCS_EXTRA): Renamed from LIBFUNCS*.
+	(for-bootstrap, rest.encap): Depend on gnulib, not GNULIB2_TARGET.

+	* cplus-class.c (finish_struct): Conditionalize EMPTY_FIELD_BOUNDARY
+	on whether or not it is defined.  Similarly for	PCC_BIT_FIELD_MATTERS. 
+

+
+	* cse.c (fold_rtx): When folding dispatch table, stay inside bounds.
+
+Wed Jan 16 08:11:48 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* reload.c (find_reloads_toplev): Fix typo in recent change.
+
+	* reload1.c (eliminate_regs): If we have a non-paradoxical
+	(subreg (pseudo)) and the pseudo has an equivalent memory
+	location, replace the SUBREG because find_reloads may do it.
+
+Tue Jan 15 01:41:28 1991  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* loop.c (scan_loop): Condition for movability was wrong.
+	A reg that isn't necessarily set may be unsafe
+	even if used only inside the loop.
+	However, a reg used only in the same basic block after the set is safe.
+	So is a reg that isn't a user-level variable.
+
+	* loop.c (loop_optimize): Reverse order of scanning loops.
+
+	* loop.c (scan_loop): After skipping the insns of a libcall sequence,
+	ignore notes when searching back to find the last insn of the seq.
+

+	same.
+
+	* cplus-lex.c (input_from_saved_text): New function.  Set string
+	source for FILE pointer.
+	(yylex, do_pending_inlines): Call it.
+
+	* cplus-parse.y (stmts, stmt): Type is now `tree'.  Some actions
+	fixed to return it.
+
+	* cplus-lex.c (reinit_parse_for_block): New function, with most of
+	the guts of reinit_parse_for_method.  Magic argument IS_TEMPLATE
+	chooses a set of error messages.
+	(reinit_parse_for_method): Call it.
+	cplus-template.c (reinit_parse_for_template): New function, also
+	calls reinit_parse_for_block.
+
+Mon Jan 14 07:20:36 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* loop.c (skip_consec_insns, move_movables, strength_reduce): Don't
+	call find_reg_note on a NOTE.
+
+Sun Jan 13 15:45:23 1991  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* cccp.c: Separate namespace for assertions.  Don't expand macros
+	inside assertions in #if.  Allow arbitrary token sequences.
+	(rescan): Special handling after `#' if assertions_flag.
+	(expand_to_temp_buffer): New arg sets assertions_flag. Callers changed.
+	(eval_if_expression): Pass 1 for that arg.
+	(skip_paren_group): New function.
+	(assertion_hashtab, ASSERTION_HASHSIZE, ASSERTION_HASHNODE): New.
+	(assertion_install, assertion_lookup, delete_assertion): New functions.
+	(T_ASSERTION): Deleted.
+	(tokenlist_list): Renamed from arglist_list.
+	(read_token_list): Renamed from read_keyword_list.  Much changed.
+	Copy the strings into the heap.
+	(free_token_list): Renamed from free_keyword_list.  Free the strings.
+	(do_assert, do_unassert): Considerably changed.
+	(check_assertion): Somewhat changed.
+	(check_macro_name): Extra arg contributes to error message.
+	* cexp.y (yylex): Parse everything as a name if keyword_parsing.
+	(rule for assertions): Set, then clear, keyword_parsing.
+	(keywords): Allow empty sequence.  Allow nested parens.

+
+	* c-typeck.c (build_unary_op): Make better code for simple casts.
+

+
+	* regclass.c (regclass): reg_n_sets is one per set.  It does not

+
+	* cplus-class.c (modify_vtable_entries): In case we are modifying
+	the main vtable, start with the vtable that comes from the immediate
+	baseclass, not the most base class.  This is needed because later

+

+
+	* expmed.c (emit_stor_flag): Try to convert some comparisons with

+	Explicitly test sign bit of STORE_FLAG_VALUE rather than testing it
+	for being less than zero.

+	Use GET_RTX_CLASS instead of comparison_code_p.

+	saving the change.  If in_group == 0, call apply_change_group.
+	(apply_change_group): If recog_memoized fails, see if we have a

+	agree with the order written.

+
+	* sparc.md (fix_truncdfsi2 recognizer): xoperands must have 3

+
+	* calls.c (emit_call_1): If we have call_pop, use it if we have

+	relational_op.
+	* tm-vax.h (PRINT_OPERAND_PUNCT_VALID_P): "C" is not punctuation.
+
+	* reload1.c (reload_as_needed, forget_old_reloads_1): Don't clear
+	reg_has_output_reload and reg_is_output_reload for each insn, just

+
+	* emit-rtl.c (emit_insn_before, emit_insn_after, emit_insn): Return

+	We no longer make a SEQUENCE with XVEC == 0, so don't test for it.

+
+	* cplus-typeck.c (c_expand_return): Handle case when we try

+	be called from gcc.c.
+
+	* tm-rs6000.h (REG_ALLOC_ORDER): Put r12 after r13; it might be

+
+	* sparc.md: cc_status no longer handles condition code updates.
+	Instead, condition codes are explicitly set and used via
+	hard register 0.  Special attributes specific to condition codes
+	(such as whether conditional branches should test the integer or
+	floating-point condition codes, or that the condition codes cannot
+	be tested for a condition which would test the overflow bit) are
+	handled by encoding the attribute in the mode for the condition
+	code register.
+	(type attributes): type "unary" insns have one input operand (1)
+	and one output operand (0)
+	type "binary" insns have two input operands (1,2) and one output (0)
+	type "compare" insns have one or two input operands (0,1) and no output
+	type "move" and type "arith" have been deleted.
+	(prescan attribute): Deleted.  Machine description now puts
+	floating-point zero in registers when needed.
+	(use_cc attribute): Deleted.
+	(fpcc define_delay): No longer depend on "use_cc" attribute.
+	Also, fpcc delay characteristics hold for "fpcc" type insns.
+	(cc attribute): Deleted.
+	(cmpxx patterns): Now written as `define_expand's so we can stow
+	away operands.	When the pattern that will use the results of the
+	conditional test is emitted, it can use these operands to figure
+	out the right way to emit the compare.
+	(bcc patterns): Rewritten to emit comparison (based on stowed-away
+	info) before emitting branch.
+	(scc patterns): Handle all the cases with branch-free code.
+	Added new pattern to recognize (x + (i == 0)).
+	(movsi pattern recognizer): Split into two patterns so that e.g.
+	"(set:SI (mem:SI ...) (const_int 5))" is never considered valid.
+	Instead this has to be a two-insn sequence.
+	(mov{hq}i pattern recognizers): Ditto.
+	(movstrsi): Force operands[2] out of memory if it was in memory.
+	({zero,sign}_extendXY): Now written as `define_expand's instead of
+	`define_insn's for more accurate machine modeling.
+	Added new pattern to optimize bit-field compares.
+	(floatsisf2 patterns): Delete redundant setting of "in_call_delay"
+	attribute.
+	(fix_trunc{sf,df}si2 pattern): Use clobberable register in which
+	the conversion can take place.	Used to use %f30,%f31.
+	({add,sub}di3 pattern): Put explicit clobber of (reg 0) in the
+	pattern.
+	(negdi2 pattern): Ditto.
+	Added new patterns to handle merging of addition/subtraction with
+	condition code testing (with (reg:CC_NOOV 0)).
+	({and,ior,xor}cbsi3 pattern): Obsolete.	 Deleted.
+	Added patterns to represent setting of condition codes in addition
+	to performing logical operations.

+	to use a C action instead of a simple template.
+	(ash{l,r}{hi,qi}3): Define patterns for shifts on sub-SImode
+	operands.
+	(jump pattern): Use `*' print code to obviate the need for a C
+	action when a template can do.
+	(tablejump pattern): Ditto, with `^' code as well.
+	Deleted `define_split's that were used to handle mem-mem moves in
+	the case of PIC generation.  Since all move insns are emitted and
+	maintained as SPARC-valid insns, these should no longer be needed.
+	(various patterns): (HI ...) is spelled (HI:SI ...).  Also, use
+	`gen_lowpart' instead of building subregs directly.
+	New `define_split's were added to split scc insns into simpler
+	components which have single-insn templates.
+	Fixed a return peephole when returning a SFmode value (it was
+	missing the "ret"!).
+	Lots of complicated peepholes that brought cc testing and
+	arithmetic operations together were deleted.  This is because the
+	combiner should now handle all these cases.
+
+	* out-sparc.c (sparc_compare_op{0,1}): New global variables.
+	Used to hold the operand(s) to compare insns in lieu of emitting a
+	compare.

+	(cc_arithop): Now returns 0 for PLUS and MINUS.
+	(cc_arithopn): Now returns 0 for XOR.
+	(gen_compare_reg): New function.
+	(sparc_address_cost): Simplified because it turns out it doesn't
+	matter what is returned for illegitimate addresses.
+	(hard_regno_mode_ok): Updated to use these new #defines.
+	(C_MODES): New #define, for condition code modes.
+	(S_MODES): Ditto, for single-word (and smaller) quantities.

+	(REG_CC0_RTX, CC0_REGNUM): Deleted.
+	(EXTRA_CC_MODES): New modes CC_NOOVmode and CCFPmode.  The former

+	(SELECT_CC_MODE): New macro.
+	(FINAL_PRESCAN_INSN): Deleted.
+	(CC_* macros): Deleted.
+	(PRINT_OPERAND_PUNCT_VALID_P): New valid chars are '#' (for
+	whether to print a noop or not), '*' (for whether to print a ",a"
+	or not), and '^' (for whether to emit code for PIC branch or not).
+	(PRINT_OPERAND{,_ADDRESS}): Replace calls to fprintf by calls to
+	fputs where that is convenient.
+
+	* expr.h, cplus-dbxout.c: #ifdef BYTES_BIG_ENDIAN should be #if.
+
+	* reload.c (struct replacement): Add new field subreg_loc.

+
+	* loop.c (get_condition): Try a little harder to find the setter of

+	If result is constant, just return it.
+	Accepts an argument saying how to normalize the result and does

+	(do_store_flag): Rewritten, now lets emit_store_flag do most of
+	the work.
+	Handles the special-case of comparing a single bit with zero.,
+	Add additional argument ONLY_CHEAP; if non-zero, fail if it looks like
+	this will be an expensive operation; all callers changed.
+	If it looks like it will be possible to do a store-flag operation,
+	call emit_store_flag; if it can't do it, emit as assignments and a
+	jump.  If it doesn't look possible to do a store-flag operation, return
+	zero before expanding anything.
+	* final.c: (final_scan_insn): Don't check STORE_FLAG_VALUE; if the

+	(expand_exit_loop{,_if_false},expand_continue_loop): Accept pointer
+	to nesting structure, substitute loop_stack if 0 (same behavior as
+	before when there was no argument), so F90 CYCLE and EXIT statements
+	(like C's continue and break stmts) can refer to other than the
+	innermost loop.
+	(expand_start_cond): Uses new names for if-related labels that
+	reflect addition of "elseif" call, and sets endif_label to whatever
+	exit_label gets set to (so we don't generate two identical labels
+	for languages from which if is exitable via expand_exit_something).
+	(expand_start_elseif): New function, used by Fortran.
+	(expand_start_else): Moved above _end_cond so these four functions
+	appear in the order they get called; uses new names, and fills in
+	only endif_label if needed, not exit_label.
+	(expand_end_cond): Handles end of any if, not just if-without-else.
+	Generates both labels for next else/elseif pending (there was none)
+	and the endif itself, if they exist (and there will always be at least
+	one).
+	(expand_end_else): Gone, call expand_end_cond instead.
+	* c-parse.y, cplus-parse.y, objc-parse.y: Pass new 0 argument to

+	and change their return types accordingly.

+	* recog.c (check_asm_operands): Move to here; no longer static.
+	(validate_change): Don't assume change is valid is asm_noperands >= 0.
+	If recog_memoized returns < 0, accept change if asm_noperands >= 0
+	and check_asm_operands returns non-zero.
+	(apply_change_group): Likewise.
+	(validate_replace_rtx_1): Swap operands on commutative operation
+	if first is constant.
+	Use plus_constant to simplify a PLUS with CONST_INT as second operand.
+
+	* reload.c (find_equiv_reg): We must have a stable SP if GOAL is
+	a MEM that uses SP.
+
+	* combine.c (try_combine): Don't do anything if I2 or I1
+	has an ASM_OPERANDS and CLOBBERS; we'll need those clobbers
+	and it is too messy to try to get things set up correctly.
+
+Sun Dec	 9 22:07:41 1990  Richard Stallman  (rms at mole.ai.mit.edu)

+Sat Dec	 8 10:40:00 1990  Tom Wood  (wood at dg-rtp.dg.com)
+
+	* m88k.md (attributes): Reorganize and include a block diagram.
+	Make better use of defaults.
+	* m88k.md (peephole), out-m88k.c, tm-m88k.h (short_branch): Add
+	the sparc peepholes for changing bsr/br into bsr.n/addu or

+
+	* make-m88k, make-m88kdgux: Say how to create m88k-trace.asm.

+
+	* tm-m88k.h, out-m88k.c, m88k.md: More cleanups: introduce
+	POWER_OF_2 for tests (x && (x & (x-1) == 0); rename predicate
+	functions *_p instead of *_operand; cleanup addsi3 insns; simplify
+	udivsi3 insns; simplify memory shift insns; make LOW_SUM and HIGH
+	SImode instead of VOIDmode; add a predicate to the increment and
+	test peephole insn; deal with setting SFmode to zero; delete bogus

+	xm-m88kdgux.h.
+	* tm-m88k.h, out-m88k.c, m88k.md: Eliminated the fixed literal

+
+Sun Dec	 2 17:47:28 1990  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+

+	for changed vector.
+
+	* out-rs6000.c (output_epilogue): Fix typo restoring general registers.
+	(print_operand): Add new option %H.
+	* rs6000.md: Add (clobber (reg:SI 64)) to many patterns even though
+	they don't clobber MQ to allow combining to work well.	This will be
+	removed once combine knows how to add clobbers when required.
+	Change patterns to reflect new canonicalization rules.
+	Where we have (and (xshift)), add patterns for (zero_extend (xshift)).
+	(andsi3, xorsi3): Fix bug in case where two insns are needed.
+	(moveti): Don't call change_address when in reload.
+	(sign_extend): Add patterns for sign extend preceeded or followed by
+	one of the shifts it will do.  Use %H to output the merged shift.
+
+	* out-romp.c (print_operand): Allow exact_log2 result to be zero.
+	* romp.md: Likewise.
+	* tm-romp.h (CONST_OK_FOR_LETTER): Likewise.
+
+	* a29k.md (type attribute): Add types for floating-point insns.
+	(in_delay_slot attribute): Update to allow for new types.
+	(function_unit definitions): Add definitions for floating-point units.

+	(movsi, movhi, movqi): No need to support special->special copies.
+	Support consthz insn on 29050.
+	(compare, scc, and branch insns): Rework to not use cc0.  Use a pseudo
+	register instead.  Compare doesn't generate any code, but merely
+	saves the operands.  scc and branch then emit the appropriate compare
+	and jump (if branch) insns.

+	(peepholes): Remove peepholes to convert jumps to scc insns; now
+	done in jump.c.

+	Add new code %J.
+	* tm-a29k.h (TARGET_VERSION): Say if compiling for 29050.
+	(TARGET_FLAGS): Add -29000 to turn off support for 29050; this is
+	still the default.
+	(various register macros): Add support for the floating-point
+	accumulators on the 29050.
+	(CONST_OK_FOR_LETTER): Use 'O' for a constant that can be set using
+	conthz on the 29050; keep old definition for 29000.
+	(STORE_FLAG_VALUE): Now 0x80000000.
+	(ASM_FILE_START): Write ".cputype 29050" when compiling for 29050.
+
+	* combine.c (subst): Put NOT, NEG, MULT, PLUS, and MINUS as the
+	first operand of commutative operations.  Note that NOT used to be
+	put as the second operand but it has always been assumed that 
+	MULT would be the first operand in address expressions, so we have
+	to change the previous canonicalization.  This is possible now that we
+	have eliminated the andcbm3 operations.
+	* i860.md (andnot): Remove obsolete andcbsi3 name and place NOT
+	as first operand.
+	* m68k.md (fpm*): Delete patterns with MULT as second operand and
+	use "@" construct when possible.

+	Delete patterns with NOT as second operand.
+	(xor.c): Rewrite in new canonical form.

+	Remove obsolete names andcbsi3, iorcb3, and xorcbsi3.
+	Rewrite xnor into new canonicalized form.
+	Add mode to HIGH and LO_SUM operations.
+	* vax.md (bic*): Remove obsolete andcbm3 names.
+	Put NOT as first operand when both generating and recognizing RTL.
+	(jlbc): Rewrite with NOT as first operand.
+

+
+Sat Dec	 1 16:31:30 1990  Ron Guilmette	 (rfg at ncd.com)
+
+	* dwarfout.c (lookup_filename, dwarfout_finalize): changed from
+	maintaining a linked list of filename entries to maintaining an
+	(expandable) array of filename entries instead.	 Also, changed
+	code so that *all* filename strings are output (to the .files
+	section of the asm file) in one swell foop just as the asm file is
+	being finalized rather than writing out new filenames one-by-one
+	as they arise (as previously). This circumvents a problem caused
+	by rfg's naive assumption that assemblers kept a stack of prior
+	section names (of depth > 1) which could be successively popped
+	via multiple `previous' directives.  For some assemblers, the
+	depth of the stack is only 1 and they can get confused if you do
+	two (or more) `previous' directives in a row.  Anyway, it is no
+	longer either necessary or useful to do that, so who cares.
+
+	* dwarfout.c: added code to output newlines to the asm file just
+	prior to each and every change of section (for better readability
+	of the asm files).
+
+	* dwarfout.c: changed code so that if DWARF_DESCRIBE_USED_EXTERNS
+	is defined, it forces DWARF_LOCATION_ATTRIBUTES to also be defined.
+
+	* dwarfout.c: changed code so that if DWARF_LOCATION_ATTRIBUTES
+	is defined, it forces DWARF_DESCRIBE_FILES to be defined (to `1').
+
+	* dwarfout.c: changed code so that if DWARF_DESCRIBE_FILES is not
+	already defined (in the user's tm.h file) it will automatically be
+	defined (by default) to `1'.  Also changed all instances of
+	`#ifdef DWARF_DESCRIBE_FILES' to `#if DWARF_DESCRIBE_FILES'.
+	The user must now intentionally *disable* this feature (by
+	defining DWARF_DESCRIBE_FILES to `0' in his tm.h file) if he
+	wishes to have the additional information about files suppressed.
+
+	* dwarfout.c: changed comments relating to optional defines for
+	extended GNU DWARF features to include more information and to
+	add some additional clarity.

+	We are allowed to reverse floating-point EQ and NE comparisons.
+
+	* combine.c (subst): Call simplify_and_const_int for all AND
+	and ZERO_EXTEND cases and all cases where we make one of them.
+	Remove all other code in AND and ZERO_EXTEND cases.
+	(simplify_and_const_int): Rewritten to follow a consistent model
+	of tracking what AND's need to be done and which bits are not
+	significant.  Consistently try a ZERO_EXTEND for all cases where
+	the result is an AND with a mode-wide mask.  Move all remaining
+	cases from AND any ZERO_EXTEND cases from subst.

+
+Fri Nov 30 10:39:04 1990  Michael Tiemann  (tiemann at cygnus.com)
+
+	* cplus-decl.c (finish_function): Use CLASSTYPE_ASM_WRITTEN instead
+	of TREE_USED to indicate that we need debugging info for
+	TTYPE.
+	Note that nobody ever sets EXTENDED_DBX_DEBUG.	For now,
+	change to test DBX_DEBUG.  For later, change everything to
+	key off of EXTENDED_DBX_DEBUG.	
+	Also, set `warn_return_type' to one always, since this warning
+	is too valuable to lose.
+	* cplus-tree.c (lang_output_debug_info): Don't test TREE_USED.	That
+	field is already used by other routines, and we have all we need now
+	in CLASSTYPE_ASM_WRITTEN.

+	(record_dead_and_set_regs): Set reg_last_value to source

+	(subst): Use reg_last_set_value instead of interpreting the
+	insn in reg_last_set as if it was a single SET.
+
+	* combine.c (gen_lowpart_for_combine): Call gen_lowpart for CONST_INT.
+	When making a new MEM, copy MEM_VOLATILE_P and MEM_IN_STRUCT_P.
+	If cannot recognize the argument, just form a SUBREG; usually,
+	it won't be recognized, but sometimes will allow further
+	simplifications.
+
+	* regclass.c (reg_scan): Save size of uid map; reallocate if
+	we have more registers than we allocated.

+	* tm-m88kdgux.h, tm-v88r32.h, tm-m88ksvr4.h: New files.
+	* xm-m88kdgux.h, xm-v88r32.h, xm-m88ksvr4.h: New files.
+	* make-m88k, make-m88kdgux: New files.
+	* config.gcc (m88k-dgux, m88k-v88r32, m88k-svr4): New alternatives.
+
+	* gvarargs.h, gstdarg.h: Include alternate file for m88k.
+
+	* expr.c (expand_expr): For ARRAY_REF, preserve const and volatile.
+
+	* expr.c (expand_builtin): Handle strcmp and memcmp with function calls
+	if can't be open coded.
+
+	* function.c (expand_function_end): Round trampoline addr to init.
+	(round_trampoline_addr): Fix braino in alignment.
+
+Thu Oct 25 14:54:18 1990  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* jump.c: Now includes insn-config.h.
+	(jump_optimize): inequality_comparisons_p takes only one operand again.
+	(can_reverse_comparison_p): Handle case where a register is used
+	for the condition code; if we can't easily find the COMPARE that
+	was used to set the register, say we can't reverse the comparison.
+	* Makefile.in (jump.o): Now includes insn-config.h.
+
+	* jump.c (jump_optimize): Put back change removed on Oct 21st;
+	emit_store_flag has now been updated.
+
+	* rtlanal.c (inequality_comparisons_p): Reject any ordered
+	comparison; we need not just reject when comparing against
+	cc0_rtx.
+	* recog.c (next_insn{,s}_test_no_inequality): inequality_comparisons_p
+	again has only one operand.
+	* genattrtab.c (cc0_rtx): No longer needed; remove change of Oct 21.
+
+	* genconfig.c (have_cc0_flag): New variable.
+	(walk_insn_part): Set it when we see CC0.
+	(main): Write #define HAVE_cc0 when it is set.
+	* flow.c: Now includes insn-config.h.
+	* Makefile.in (flow.o): Likewise.
+
+	* combine.c (subst): If X and FROM are the same register number,
+	but in different modes, force the combine not to be done.
+	Add missing initialization of undobuf.storage.
+
+Thu Oct 25 11:34:35 1990  Michael Tiemann  (tiemann at cygnus.com)
+
+	* sched.c (new_sometimes_live): Protect this function in case it is
+	called with (OFFSET,BIT) that evaluates to >= MAX_REGNO.
+
+	* jump.c (sets_cc0_p): Conditionalized to abort if called when
+	machine does not support cc0.
+
+	* rtlanal.c (reg_set_p): Now non-static.
+	* rtlanal.c (rtx_varies_p): Handle LO_SUM more accurately.
+	* rtlanal.c (find_next_ref): New function.  Returns the insn that
+	next references REG after INSN, or 0 if REG is clobbered before next
+	referenced or it cannot easily find a reference to REG.
+
+	* recog.c (next_insn_tests_no_inequality): Conditionalized on
+	HAVE_cc0.
+
+	* rtlanal.c (inequality_comparisons_p): Takes new argument
+	THIS_CC0_RTX which is the rtl for the condition code value we are
+	concerned about testing.  All callers changed.
+
+	* flow.c (propagate_block,mark_used_regs): Conditionalize
+	specialized cc0 handling only if HAVE_cc0 is defined.
+
+	* genemit.c (gen_exp): In REG case, If CC0_REGNUM is defined,
+	save space by using REG_CC0_RTX instead of allocating a new
+	(REG, mode, CC0_REGNUM) rtx if the mode is SImode.
+
+	* final.c (output_addr_const): Handle PC for P.I.C. code generation.
+	Also, put parens around CONST expressions so that precedence can be
+	maintained.
+	* final.c (final_scan_insn): Don't look for redunant compares
+	except when HAVE_cc0 is defined.
+	Also, use `find_cc' to locate the rtx functioning as the
+	condition code register in order to perform appropriate calls
+	to `alter_cond'.
+
+	* expr.c (expand_expr): Supply missing arg in calls to `store_expr'.
+
+	* expmed.c (emit_store_flag): New argument COMPARISON is the
+	comparison operation whose result we store.
+
+	* recog.c (offsettable_address_p,adj_offsettable_operand): Use
+	`plus_constant_for_output' instead of `plus_constant' since we
+	are testing conditions which rely on being able to add small
+	offsets to e.g. LO_SUM operands.
+	* explow.c (plus_constant): No special handling for LO_SUM.  It is
+	not valid to add a constant to a term with LO_SUM, since the
+	constant may need to be added to the high bits that form the sum,
+	and those high bits are not readily available.
+	* explow.c (plus_constant_for_output): Same as `plus_constant'
+	except that we do allow adding constants to LO_SUM terms.  This
+	function works only in special cases such as for
+	`adj_offsettable_operand' and `offsettable_address_p'.
+
+	* emit-rtl.c: Declare reg_cc0_rtx which is like cc0_rtx, but
+	is a register instead of a special form.  reg_cc0_rtx should
+	be used when representing the condition code register on a
+	machine where condition codes are only set if explicitly set.
+	For machines which allow arbitrary registers to be used as
+	condition code registers (such as the MIPS and 88k), normal
+	pseudo registers should be used instead.
+	* emit-rtl.c (next_cc0_user,prev_cc0_setter): Conditionalized
+	on HAVE_cc0.
+	* emit-rtl.c (find_cc): New function.  Given INSN, returns
+	the rtx of what functions as the condition code register for
+	INSN.  On machines which use cc0_rtx, this is always cc0_rtx.
+	On machines which have a dedicated register for cc0, this is
+	that register.	On machines which allocate pseudos for holding
+	condition codes, this is the pseudo found in a REG_CC0 note.
+	Otherwise, this function returns 0.
+	* emit-rtl.c (init_emit_once): Allocate `reg_cc0_rtx' if
+	CC0_REGNUM is defined.
+
+	* cse.c (make_regs_equiv): Don't consider making a reg
+	equivalent to another reg whose class is NO_REGS.
+	* cse.c (canon_reg): Don't canonicalize a register to
+	one whose class is NO_REGS.
+	* cse.c (fold_rtx): Conditionalize code for handling cc0_rtx
+	with HAVE_cc0.
+	* cse.c (predecide_loop_entry): Generalize code to use either
+	a register or cc0_rtx.
+	* cse.c (cse_insn): Conditionalize code for handling cc0_rtx
+	with HAVE_cc0.
+
+	* combine.c (combine_instructions,try_combine,subst):
+	Conditionalize code handling cc0_rtx with HAVE_cc0.
+	* combine.c (simplify_set_cc0_and): Abort if HAVE_cc0 is not
+	defined.
+	* combine.c (try_distrib): Add break at end of switch cases.  It is
+	dangerous to leave the last cases of a switch statement to fall
+	through since new cases added after will get fallen into.
+
+	* recog.c (validate_change): Always succeed for an asm insn,
+	since recog always fails to recognize asm insns.  This is
+	needed for virtual register instantiation in asm insns.
+
+	* cse.c (cse_main): When following jumps, notice whether a
+	particular basic block causes CSE_JUMPS_ALTERED to become set.	When
+	this happens, repeat the scan.
+	* cse.c (refers_to_mem_p): Changed parameter name REG to BASE,
+	which is more accurate.	 Also, taught it how to cope with
+	LO_SUM rtl constructs.
+
+Wed Oct 24 15:36:12 1990  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* calls.c (store_one_arg): Accept additional arg, FNDECL.
+	Don't save argument area if it is within the REG_PARM_STACK_SPACE
+	area, but mark the area in use.
+	(expand_call): If ACCUMULATE_OUTGOING_ARGS and REG_PARM_STACK_SPACE,
+	treat the stack area for the registers as be clobbered by the called
+	routine (e.g., if it was compiled without -O) and save and restore
+	it if it was previously used for arguments in a similar manner to
+	the remainder of the argument area (done by store_one_arg).
+
+	* calls.c (expand_call): Support new description macro,
+	STACK_PARMS_IN_REG_PARM_AREA.
+	* function.c (assign_parms): Likewise.
+
+Wed Oct 24 12:47:21 1990  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* c-typeck.c (build_array_ref): Use main variant for value type.
+
+	* genoutput.c (output_prologue): Let SEPARATE_AUX_OUTPUT
+	cause aux-output.c not to be included.
+	Makefile.in (aux-output2.c): Copy aux-output.c and then compile it.
+
+	* reload.c (subst_reg_equivs): Treat HIGH like other constants.
+
+	* reload.c (push_reload): When testing hard reg for validity,
+	test subsequent regs only against class, not for HARD_REGNO_MODE_OK.
+
+Tue Oct 23 22:49:33 1990  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* cccp.c (collect_expansion): Skip ## at start after the error.
+
+	* gcc.c (default_compilers): Handle - as suffix.
+	(main): Make that a special case; it matches only exactly `-'.
+
+Tue Oct 23 22:40:33 1990  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* romp.md (store{s,h,q}i pattern): Allow "b" for clobbered pseudo
+	in addition to "d" in first alternative.
+
+	* reload1.c (eliminate_regs): IF_THEN_ELSE isn't a unary operation.
+
+Tue Oct 23 20:35:13 1990  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* m68k.md (zero-extend QI): When pushing, store value at 1(sp).
+
+Mon Oct 22 12:27:08 1990  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* cccp.c (rescan): In the loop that handles numbers, discard \newline.
+	Also make `..' terminate a preprocessing number.
+
+	* Makefile.in (tmpgnulib, stamp-gnulib2): Do `set -e'.
+
+	* gcc.c (default_compilers): Give __GNUC__ value 2.
+	Don't define it for .S files.
+
+Mon Oct 22 07:33:42 1990  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* optabs.c (emit_indirect_jump): New function; now checks predicate
+	of indirect_jump.
+	* stmt.c (expand_computed_goto, expand_goto): Use new function instead
+	of directly emitting indirect jump.
+
+	* flow.c (mark_set_1): Make LOG_LINKS for hard registers.
+	* combine.c (subst): Make new macro COMBINE_RTX_EQUAL_P which
+	considers things equal if they are the identical RTX or the same
+	register with the same mode; use to see if something changed and
+	if we have a match.
+
+	* cccp.c (S_ISREG): Use argument instead of global.
+	(main): Correct sense of S_ISREG usage.
+	(check_precompiled): Use S_ISREG.
+
+	* flow.c (mark_used_regs): Don't allow reg_next_use to point to
+	a NOTE; either point it to replacement insn or invalidate it.
+
+Mon Oct 22 00:13:12 1990  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* c-parse.y (xdecls): No warning unless -pedantic.
+
+Sun Oct 21 17:49:24 1990  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* genattrtab.c (cc0_rtx): Define, referenced in rtlanal.c.
+
+	* jump.c (jump_optimize): Remove code that depends on changes to
+	emit_store_flag that haven't been made yet.
+
+	* expmed.c (extract_bit_field): Correctly check for bitfield
+	completely filling a mode.
+
+	* out-romp.c (output_epilogue): Correctly write number of words of
+	arguments into trace table.
+
+	* calls.c (store_one_arg): Fix error in change of Oct 19th.
+
+	* reorg.c (mark_target_live_regs): Revert back to old behavior
+	of scanning all insns, even those in delay slots.
+	(fill_simple_delay_slots): Need only call update_block if we move
+	an insn across a label.
+
+	* Makefile.in (LIBFUNCS): Use consistent naming convention for
+	comparison routines; gnulib.c was always correct.
+
+	* function.c (assign_parms): Don't overwrite DECL_INCOMING_RTL when
+	we are called for the second time.
+
+	* integrate.c (initialize_for_inline): Don't make a new return label
+	here; the maximum label number has already been computed.
+	(save_for_inline_copying, save_for_inline_no_copy): Do it here instead.
+
+	* reload.c (find_reloads_address): For indirect address where the
+	underlying address is also invalid, ensure that we substitute into
+	the MEM that we will use.
+
+Sun Oct 21 14:12:47 1990  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* reload.c (find_equiv_regs): Reject reg that overlaps goal.
+
+	* expmed.c (extract_bit_field): For big fields, make sure
+	value really goes in the target.
+
+	* expr.c (expand_builtin): Delete __builtin_varargs.
+	(EXPAND_BUILTIN_SAVEREGS): New macro says how to do __builtin_saveregs.
+
+	* calls.c (expand_call): No "can't inline" warning if -fno-inline.
+
+	* stddef.h: Add missing #endif.
+
+Sat Oct 20 14:33:14 1990  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* function.c (round_trampoline_addr): New function.
+	(trampoline_address): Use that.
+
+Fri Oct 19 15:13:31 1990  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* calls.c (store_one_arg): Don't mark stack area used until after
+	we have written into it; if we do it before, the restore might
+	clobber a function result being put into that stack area.
+
+	* objc-actions.c (print_lang_statistics): Add empty function.
+
+	* recog.c (inequality_comparisons_p): Deleted from here.
+	* rtlanal.c (inequality_comparisons_p): Moved to here; not static.
+
+	* a29k.md (extendhisi2): Fix typo in define_split.
+
+	* Makefile.in (integrate.o): Includes integrate.h.
+	(reorg.o): Includes insn-flags.h.
+
+Fri Oct 19 14:49:26 1990  Michael Tiemann  (tiemann at cygnus.com)
+
+	* sdbout.c (sdbout_symbol): If a variable belongs to an inline
+	function, the decl's rtl may not be rewritten by alter_reg.  So if
+	we have a variable allocated to a pseudo, just get the hard register
+	number from `reg_renumber'.  ?? But I thought that COFF was so
+	losing that it was decided one could not represent debug info for
+	inline functions in COFF.
+
+Fri Oct 19 13:21:25 1990  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* fold-const.c (split_tree): Use NEGATE_EXPR to negate *conp.
+
+Fri Oct 19 00:15:21 1990  Michael Tiemann  (tiemann at cygnus.com)
+
+	* version.c: Bumped to 1.90.03.
+
+	* tree.c: Added facility for gathering statistics on the number of
+	tree nodes allocated and the size in bytes they occupy.	 The
+	statistics are by tree_node_kind, which is almost like using the
+	tree code letter, but has more resolution for dealing with different
+	kinds of `x' nodes.  The facility is enabled by compiling the
+	compiler with -DGATHER_STATISTICS and using the -fstats flag.
+
+	* expr.c (do_tablejump): Emit a BARRIER after the jump that performs
+	the tablejump.
+
+	* cplus-typeck.c (c_expand_return): Rewritten so that the function
+	value return register is not used except as a target of the function
+	return value.
+
+	* cplus-tree.c (build_cplus_new): New argument WITH_CLEANUP_P
+	controls whether this functino should build its result with a
+	cleanup or not.	 All callers changed.
+
+	* cplus-lex.c: File updated to latest changes to c-parse.y's lexical
+	analyzer.
+
+	* cplus-except.c (cplus_expand_raise): New parameter FOR_RERAISE
+	is used to control whether to output extra gotos or not.  When
+	nonzero, the compiler can avoid writing out the extra gotos that are
+	otherwise needed to avoid warning messages.
+
+	* cplus-decl2.c (flag_short_double): Add support for this option.
+
+	* cplus-decl.c (finish_function): Always cause returns to jump to
+	the return label.  This allows -Wreturn to give meaningful error
+	messages.
+
+	* jump.c (invert_exp): Make this non-static.
+	(jump_optimize): Reorganization and simplification of main inner
+	loop.  Comments added explaining what the optimizers are looking
+	for.  New optimization added that optimizes for consecutive testing
+	of an inequality test followed by an equality test (or vice-versa).
+	Changes made to accommodate reorg.c on Sparc.  Code for
+	cross-jumping return statements was previously dead in this
+	function; as a result of the reorganization, it is now live.
+	(find_cross_jump): Added temporary variable PREV1 to hold return
+	value of `prev_nonnote_insn' instead of calling the function 3 times
+	in a row.  Also changed so that USE or CLOBBERS are not cross-jumped
+	unless some real insns are also cross-jumped.  This helps reorg.
+	(redirect_jump): Fixed a return that returned no value so that it
+	returns 1.
+	(rtx_renumbered_equal_p): Test that reg_renumber is nonzero before
+	using it.  We may want to call this function earlier than by the
+	time that array has been initialized.
+
+	* integrate.c (save_for_inline_{copying,nocopy}): New functions to
+	replace `save_for_inline'.  save_for_inline_copying saves the rtl
+	for inline functions by copying the rtl to the
+	maybepermanent_obstack.	 It is called when the rtl of the current
+	function is going to be compiled immediately.
+	save_for_inline_nocopy takes advantage of the fact that inline
+	function rtl is already allocated to the maybepermanent_obstack, and
+	need therefore not be copied if it's not going to be modified by the
+	compiler (such as by `rest_of_compilation').
+	({initialize_for,finish}_inline): New helper routines for
+	save_for_inline_... functions.
+	(note_modified_parmregs): Function called by `mark_stores' to note
+	whether parameters are assigned to in the body of an inline
+	function.
+	New interface, integrate.h, provides declarations for functions used
+	by other routines that might want to copy chunks of rtl.
+	({save,try}_constants): Now global (for integrate.h).
+	(mark_stores): Ditto.
+	(try_fold_condition): Ditto.
+
+	* dbxout.c (dbxout_symbol): If a variable belongs to an inline
+	function, the decl's rtl may not be rewritten by alter_reg.  So if
+	we have a variable allocated to a pseudo, just get the hard register
+	number from `reg_renumber'.
+
+	* varasm.c (output_const_pool): No longer static.
+	(assemble_variable): Do output debugging information for global
+	register variables.  GDB does the right thing for global register
+	variables.
+
+	* toplev.c: New flag `warn_inline' for warning when a function
+	declared inline was not in fact inlined.  Also, new flag
+	`flag_no_inline' which disables function inlining, but retains
+	other properties of inline functions (such as lazy compilation
+	and write-only-if-needed).
+	* toplev.c (compile_file): Changed logic for inline function
+	handling to work with `warn_inline' and `flag_no_inline'.
+	Also modified to call `save_for_inline_nocopy' when insns are to be
+	saved but not immediately compiled.
+
+	* function.c (instantiate_decls): If instantiating a function
+	which was saved for inline expansion, preserve the rtl created
+	by the instantiation as well.
+
+	* flags.h (flag_no_inline): New flag; if nonzero, then no
+	calls are inlined, regardless of their declaration.  We still
+	save the insns for these functions in DECL_SAVED_INSNS so that
+	the functions need not be written if they are never called.
+
+	* calls.c (expand_call): If `flag_no_inline' is set, don't
+	inline the call, regardless of whether it was declared inline
+	or not.
+
+Thu Oct 18 13:10:26 1990  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* rtl.def (CODE_LABEL): Add new string field.
+	* rtl.h (LABEL_NAME): Define macro for access.
+	* emit-rtl.c (gen_label_rtx): Initialize it to 0.
+	* stmt.c (expand_label): Store proper name of label.
+	* final.c (final_scan_insn): Call sdbout_label.
+
+	* tree.h (built_in_function): Add BUILT_IN_VARARGS.
+	* c-decl.c (init_decl_processing): Declare __builtin_varargs.
+	* expr.c (expand_builtin): Generate code for it.
+	Uses new macro EXPAND_BUILTIN_VARARGS.
+
+	* sdbout.c (SDB_IS_FAKE): Macro deleted.
+	(MAKE_LINE_SAFE): New macro.
+	(sdbout_begin_block, sdbout_end_block, sdbout_end_function): Use it.
+	(sdbout_one_type): Delete spurious second arg in all callers.
+	(sdbout_types, sdbout_end_function):
+	Use sdbout_dequeue_anonymous_types.
+	(sdbout_label): New function.
+
+	* expr.h (FUNCTION_ARG_BOUNDARY): Default is now PARM_BOUNDARY.
+
+	* gvarargs.h, va-*.h (va_dcl):
+	Add ellipsis so current_function_varargs is set.
+
+	* jump.c (jump_optimize): Exit push-optimize loop at end of insns.
+
+Thu Oct 18 07:09:06 1990  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* reorg.c: Major reorganization.  Many special cases have been moved
+	into more general code and an overall restructuring has been done.
+	Numerous bugs have been fixed.	Highlights:
+	(dbr_schedule): First make list of all insns needing filling.  Then
+	iterate for two passes.	 In each pass, try two methods of filling
+	delay slots, then do some canonicalizations, which may create more
+	insns to fill.
+	(fill_simple_delay_slots): Now uses list of insns that need filling,
+	rather than making such a list.
+	Enhance code that finds insns when code paths merge to allow multiple
+	uses of the label as long as all uses are in the skipped code.
+	(struct resource): Notice volatile memrefs.
+	(stop_search_p): Allow option to continue when label is reached.
+	(find_end_label, make_return_insns): New functions; when we have a
+	filled branch that is really a RETURN, first convert it to a jump
+	to a return label and then later see if the insns in the delay slots
+	are also valid for a RETURN.
+	(mostly_true_jump): Test for branch to loop beginning rather than
+	branch at end of loop.	Also, conditional return insns predict false.
+	(own_thread_p): New function to replace fall_through_to_p.
+	(try_merge_delay_insns): Only support merging insns already in an
+	insns delay list.
+	(get_branch_condition, condition_dominates_p): New functions.
+	(steal_delay_list_from_{target,fallthrough}): New functions to
+	replace steal_delay_list.
+	(redundant_insn_p): New function.
+	(update_block, mark_target_live_regs, dbr_schedule): When moving
+	an insn not at the front of the basic block to a delay slot,
+	leave a "ghost" USE so that we can track things livened and killed.
+	(fill_slots_from_thread): Eliminate use of static vars for number
+	of slots to fill and already filled.
+	Try to modify an insn that follows a register-register copy to use
+	the original register; this may create a delay-slot opportunity.
+	(try_hoist_target{,_1}): Deleted.
+	(relax_delay_slots): Rewritten to just perform canonicalizations
+	previously done elsewhere.  No actual delay slot filling is done
+	here.  Any new delay slots created will hopefully be filled in the
+	next pass around the loop in dbr_schedule.
+
+	* expr.c (emit_push_insn): Don't try to compute a SUBREG of a
+	hard register in a non-integer mode when pushing a "partial" arg.
+
+	* recog.c (validate_change, apply_change_group): After reload, ensure
+	that operands meet the constraints by calling constrain_operands.
+	(validate_replace_rtx_1): Consider two rtx equal if they refer to
+	the same register.
+
+	* jump.c (jump_optimize): Extend change of Oct 16th to handle
+	the other usage of find_equiv_reg; remove invalid death notes there.
+
+	* rs6000.md, tm-rs6000.h, out-rs6000.c, xm-rs6000.h, make-rs6000:
+	New files.
+
+	* out-a29k.c (extract_subword): Use gen_{high,low}part from
+	an FP CONST_DOUBLE if host and target float formats are the same
+	or REAL_IS_NOT_DOUBLE.
+
+	* out-romp.c (output_fpop, output_fpops): Provide fr0 as a scratch
+	register unless it is used in the insn.
+
+	* romp.md: In combined set CC0 and move, optimize case where move
+	is nop.
+	(DF moves): Fix typo in generation of `get' insn.

+	(LEGITIMATE_CONSTANT_P): Data block addresses of functions are not
+	valid operands.

+
+	* cse.c (invalidate, refers_to_mem_p, cse_rtx_addr_varies_p):
+	Consider (plus (reg) (const_int)) to be a fixed address if REG

+
+	* genrecog.c (enum routine_type): Use to distinguish two types of
+	routines that we write: recog and split_insns.
+	(make_split_sequence): Write out extern for gen_split_ function.

+	(expand_expr, case *_DECL): Return constant address if

+Sat Aug 25 11:43:09 1990  Michael Tiemann  (tiemann at cygnus.com)
+
+	* final.c (alter_cond): Handle CC_INVERTED.
+
+	* conditions.h (CC_INVERTED): New flag indicating that the condition
+	tested leaves the falgs set opposite to the condition tested.  This
+	is unsafe for IEEE floating point operations, but useful for integer
+	operations which can combine with condition-code setting operations.
+
+	* c-parse.y (position_after_white_space): New function.	 Skips
+	all of the whitespace at the current location in the input
+	file, taking NEXTCHAR into account.  Changed all callers of
+	`skip_white_space' in grammar to use this function instead.
+
+	* genrecog.c (main): Generate code which is more easily optimized by
+	GCC's cse.  In particular, start each recognizer with the address of
+	`recog_operands' in a register.
+
+	* reload.c (combine_reloads): Can only combine reloads if the
+	register we find can hold the entire output reload (i.e., SFmode

+	* combine.c (combine_instructions): Fixed typo in comment.
+
+	* function.c (expand_function_end): Emit a barrier after a RETURN
+	jump.
+
+	* Added diffs for new instruction scheduling code.
+	* emit-rtl.c (try_split): Moved here from reorg.c and made
+	public.	 Both instruction scheduling and delayed branch
+	filling now use the same code to split insns.
+	* flags.h: Add new flags FLAG_SCHEDULE_INSNS for instruction
+	scheduling before register allocation and
+	FLAG_SCHEDULE_INSNS_AFTER_RELOAD for insn scheduling after
+	register allocation.
+	* recog.c (constrain_operands): Recognize pseudo registers as
+	registers for the purpose of insn constraint matching before
+	register allocation.  Otherwise, the insn scheduler assumes
+	the operands will be memory, which is usually wrong (and
+	causes it to build bad schedules).
+	* sched.c (order_calls): New function.	For two CALL_INSNS in
+	the rtl chain, we set up a constraint that the second
+	CALL_INSN may not be scheduled to run before the first.
+	(sched_analyze_*): Three kinds of dependencies (true, anti,
+	and output) constrain the order in which insns can be
+	rearranged and still preserve their execution semantics.
+	We now handle dependencies for pseudo and hard register usage
+	and for memory usage in these functions.
+	(launch_links): The ordering of which newly ready insns to
+	execute is now preserved according to their `priority' in the
+	insn chain, and no longer on their order in the dependency
+	list from which they were launched.
+	(schedule_block): Removed support for trying to schedule insns
+	taking branch delays into account.  Reorg.c should be hacked
+	to understand which insns to pull into delay slots and which
+	insns to leave alone.
+	(schedule_block): (Re-)compute all register life information here.
+	No longer dependent on flow to keep `basic_block_live_at_end'
+	allocated.
+	(schedule_insns): Recompute LABEL->BASIC BLOCK mapping, so we
+	can compute register life information.
+	* rtl.c (add_dependence): New function to add and remove insn
+	dependencies.  If an insn (I2) must execute after another
+	(I1), we add an INSN_LIST containing I1 to I2's	LOG_LINKS.
+	If such an INSN_LIST is already in I2's LOG_LINKS, we don't
+	add a second.
+	(remove_dependence): Similar, but removes dependencies.	 May
+	not actually be needed.
+	* toplev.c (compile_file,rest_of_compilation): Added code for
+	dumping info about insn scheduling.
+
+Fri Aug 24 17:24:03 1990  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* Implement `aligned (INTEGER)' attribute for real.
+	* c-parse.y (attrib): Really record info for `aligned' attribute.

+	(initdcl, notype_initdcl, component_declarator): Handle that info.
+	* c-common.c (decl_attributes): New function.
+
+Fri Aug 24 07:12:05 1990  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)

+
+	* local-alloc.c (block_alloc): Don't update qty_birth for a
+	register whose quantity is <= 0.
+
+	* fold-const.c (decode_field_reference): Actually obtain unsigned
+	type where one is wanted.
+	(merge_component_references): Correctly test for mutually exclusive
+	conditions.
+
+Thu Aug 23 14:56:44 1990  Richard Stallman  (rms at mole.ai.mit.edu)
+
+	* c-typeck.c (digest_initializer): No pedantic warning for string
+	and array of unsigned char.
+
+	* tree.c (get_identifier): Do id_clash_len stuff if length equals that.
+
+Thu Aug 23 10:30:10 1990  Michael Tiemann  (tiemann at cygnus.com)

+	* config.gcc (a29k-unix): New target.
+
+	* calls.c (expand_call): Allow FUNCTION_ARG to return an EXPR_LIST
+	specifying multiple registers to load.
+	(store_one_arg): Likewise; also delete handling of fully-in-register
+	case, which hasn't been handled here for a while.
+	* expr.c (emit_library_call): Our subset of calling sequence for

+
+	* tree.def (BIT_FIELD_REF): New tree code.

+	Remove pair of NEGATE_EXPRs and BIT_NOT_EXPRs.
+	Convert "- (a - b)" to "b - a" for non-floating-point.
+	ABS_EXPR applied to ABS_EXPR or NEGATE_EXPR is ABS_EXPR of inner arg.
+	Convert "a + (-b)" to "a - b" and "a - (-b)" to "a + b".
+	If adding ANDs with constants that have no bits, in common, try
+	bitwise-or, since we may then be able to distribute the operation,
+	e.g., (a & 7) + (a & 0x70) -> a & 0x77.
+	Add missing last arg to operand_equal_p call.
+	Call distribute_bit_expr for BIT_AND_EXPR and BIT_IOR_EXPR.

+	Don't cross-jump into the middle of a USE-CALL_INSN-CLOBBER
+	block; doing so can confuse reorg.c.
+
+	* optabs.c (expand_binop, expand_binop, expand_twoval_binop):
+	If predicate doesn't match, ensure that operand is in a pseudo
+	register.  Current code assumes that any register will suffice,
+	but an insn may want to reject certain hard registers.
+	(expand_unop, emit_unop_insn, emit_cmp_insn): Likewise.

+Sat Aug	 4 15:29:09 1990  Michael Tiemann  (rms at sugar-bombs.ai.mit.edu)
+
+	* function.c (assign_parms): For parms passed by reference,
+	make the memory object's mode agree with the parm's original
+	type mode.
+	* calls.c (expand_call): Fixed braino in building argument
+	reference when FUNCTION_ARG_PASS_BY_REFERENCE is defined.
+
+	* varasm.c (assemble_variable): Hack our way around the problem
+	that static class members look like initialized variables for the

+	common mistake of forgetting the function body.
+
+	* cplus-typeck.c (build_component_ref): Make better error message

+
+	* cplus-search.c (get_base_distance): Changed to follow leftmost
+	path only when PARENT == TYPE_MAIN_VARIANT (PARENT).
+
+	* cplus-class.c (modify_vtable_entries): Call get_base_distance

+
+	* final.c (leaf_function_p): Delete line advertently retained
+	after change of July 29.
+
+	* reorg.c (optimize_skip, try_hoist_target): Don't invert jump
+	unless can_reverse_comparison_p says it is OK.	Use invert_jump
+	to do it.
+	(fill_simple_delay_slots): Another way flow of control can merge is
+	for two insns to jump to the same place; try to get insns from there.
+	(mostly_true_jump): Return 2 for a jump very likely to be true (the
+	branch back to the start of a loop).
+	(fill_slots_from_thread): Accept new arg LIKELY.  If true, see if can
+	put increment in delay slot and undo it after the end of the loop.
+	(fill_eager_delay_slots): Pass new arg to fill_slots_from_thread.
+	If previous insn is conditional jump that also didn't get a delay
+	slot, see if swapping targets helps.

+
+	* cccp.c (MAKE_POS): Avoid constant of uncertain signedness.

+	* reorg.c: No longer uses tree.h.
+	(dbr_schedule): Get result RTL from current_function_return_rtx instead
+	of reading it from current_function_decl.
+	* Makefile.in (reorg.o): No longer depends on TREE_H.
+
+	* cse.c (remove_invalid_refs): Only invalidate an entry if it 
+	references the actual register, not merely something sharing its
+	quantity.
+	(cse_insn): Don't abort if SRC and SRC_EQUIV map to different
+	hash classes.  Merge them instead.
+
+	* romp.md (mulsi3): Emit call to lmul$$ as a regular insn
+	rather than a CALL_INSN.
+	(divsi3, modsi3, udivsi3, umodsi3, call_libfcn): Deleted.
+	(divmodsi4, udivmodsi4): New patterns to call ldiv$$ and uldiv$$

+
+Wed Aug	 1 21:56:08 1990  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
+
+	* c-parse.y (yylex): Don't warn about non-decimal unsigned by default

+
+Mon Jul 30 07:38:55 1990  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* jump.c (invert_jump): Don't do anything with labels if NLABEL 
+	equals JUMP_LABEL.
+	(redirect_jump): Don't try to reference LABEL_NUSES if olabel is
+	zero (meaning this is a return insn).
+	(redirect_exp): Handle case of converting return to jump to
+	label.
+
+	* dbxout.c (dbxout_parms): Allow parameter at zero offset from

+
+	* optabs.c (expand_twoval_binop_convert): Deleted.
+	(expand_twoval_binop): Rework to be handle predicates, modes, and
+	failures in a manner consistent with expand_binop.
+	Move code from expand_twoval_binop_convert inline and rework to
+	no longer hard-wire SImode and to handle failure.
+
+	* config.gcc: Finish change of July 24th to have make_var_file depend
+	on host machine.
+
+	* jump.c: Now includes insn-flags.h.
+	(jump_optimize): Try to put a RETURN at the end of the function if
+	control flows through to it.
+	JUMP_LABEL can now be zero for a RETURN or conditional RETURN.
+	Try to convert jump to end of function into (possibly conditional)
+	RETURN.
+	Use next_active_insn instead of next_real_insn; these do the same
+	thing prior to reload, after which USE and CLOBBERs don't matter.
+	redirect_jump may now fail so don't set CHANGED if it does.
+	Delete optimization of jump to RETURN; now subsumed by follow_jumps.
+	Reset INSN_CODE if changing conditional jump to unconditional.
+	(cond_jump_p): Conditional RETURN is conditional jump.
+	(follow_jumps): Change argument name to AFTER_RELOAD.
+	If not after reload, do not chain across a USE or CLOBBER.
+	Recognize RETURN insns.
+	(tension_vector_labels): Likewise.
+	(redirect_jump, redirect_exp): If NLABEL is zero, turn JUMP into a
+	(possibly conditional) RETURN; use validate_change to see if such an
+	insn exists. 
+	Now returns non-zero if succeeds, 0 otherwise.
+	Unconditional RETURN looks like (RETURN), not (SET (PC) (RETURN)).
+	(thread_jumps): Ignore any type of RETURN insn.
+	* Makefile.in (jump.o): Depends on insn-flags.h.
+	* loop.c (strength_reduce): Don't confuse conditional return with
+	jump to top of loop when LOOP_TOP == 0.
+	* final.c (leaf_function_p): No longer static; no longer takes an arg.
+	(final_start_function): Don't pass START to leaf_function_p.
+	* romp.md (return pattern): Convert to a named pattern.
+
+Sun Jul 29 16:05:27 1990  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)

+
+	* reorg.c (fill_slots_from_thread): Restore inadvertantly deleted

+
+Fri Jul 27 19:53:18 1990  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* Makefile.in (reorg.o): Depends on tree.h, basic-block.h, regs.h,

+	and ASM_OUTPUT_SHARED_LOCAL.
+
+	* tm-encore.h (SHARED_SECTION_ASM_OP): New macro.

+	only if little-endian.
+
+Thu Jul 26 23:19:15 1990  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
+
+	* expmed.c (expand_shift): Consistently call protect_from_queue
+	before doing anything else.
+	Always put operand1 of extzv into a register because it is SImode
+	and we assume that this means a register.
+
+Thu Jul 26 14:18:11 1990  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* varasm.c (assemble_variable): Delete dead code.
+	DATA_ALIGNMENT takes tree and current alignment and gives new
+	alignment for a non-automatic variable of that type.
+	Also apply CONSTANT_ALIGNMENT to the initial value; it now takes
+	the constant and old alignment and gives the new alignment.
+	Adjust DECL_ALIGN to the resulting alignment.
+	Use floor_log2 consistently instead of duplicating its function.
+	(get_or_assign_label): Use CONSTANT_ALIGNMENT instead of DATA_ALIGNMENT
+	and pass type instead of decl.
+	* expr.c (get_pointer_alignment): Rework to: distinguish reliably
+	between expressions giving the address and those giving the item being
+	addressed; use the alignment from the type of the object being
+	pointer to; return 0 if the type is not a pointer; and other 
+	miscellaneous changes.
+	(string_constant): Skip CONVERT_EXPR and NON_LVALUE_EXPR as well
+	as NOP_EXPR.
+	(expand_builtin): Allow get_pointer_alignment to fail, in which case
+	we call the actual function.
+	* stmt.c (expand_decl): Set actual alignment obtained into DECL_ALIGN
+	since it may be better aligned than required and get_pointer_alignment
+	can take advantage of this.
+	* tm-gmicro.h, tm-pyr.h, tm.romp-h: Add or replace definitions of
+	CONSTANT_ALIGNMENT to word-align string constants and
+	DATA_ALIGNMENT to word-align character arrarys for builtin memory
+	functions.
+
+	* fold-const.c (rshift_double): Reset carry after each shift of
+	one bit.
+
+	* vax.md (ashrsi3): If right shift by constant, emit as ASHIFTRT.

+	(fold_rtx): Convert shift with negative constant count to shift in
+	the opposite direction.
+	* combine.c (subst): Likewise.
+
+	* emit-rtl.c (init_emit_once): Initialize arg_pointer_rtx before
+	struct pointer and static chain values in case they want to use it.

+
+	* fixincludes: Handle uses of _IO* followed by spaces.
+	Change redirections for cd when testing that directory exists.
+
+	By Tiemann:
+
+	* emit-rtl.c (next_cc0_user): Handle insns in which cc0
+	is set and used in the same insn.
+
+	* final.c (leaf_function_p): Look inside INSNs which contain
+	a delayed-call sequence.
+	(final_start_function): Test `only_leaf_regs_used' before
+	`leaf_function_p', since that is likely to be faster.
+	(final_scan_insns): Normally we don't have NOTICE_UPDATE_CC
+	take action when processing the path of an annulled branch,
+	since that path does not affect the cc's of the fall-through
+	insns at all.  However, we cannot always ignore the effect of
+	the cc's when processing a delayed annulled branch: when the
+	delayed annulled branch follows a label and carries a
+	REG_CC_STATUS note, that note must be processed.
+
+	* genattr.c (main): Generate #defines for annulled branches
+	which are consistent with documentation.
+
+	* reorg.c: Finish recent rework by modifying code specific to
+	machines that have annulling branches.
+
+	* c-common.c (merge_component_comparisons): Previous logic did
+	not handle cases of (A == 1) && (B == 1), (A != 0) && (B != 0),
+	and (A != 1) || (B != 1).  Fixed by expanding the logic out
+	longhand and letting the compiler do the proper cross-jumping.
+
+	* tm-vms.h (ASM_OUTPUT_EXTERNAL): Use assemble_name.
+
+	* expr.c (expand_expr): For BIND_EXPR, do the init for all vars.
+
+	* stupid.c: Include flags.h.
+	* genrecog.c (main): Make insn-recog.c include flags.h.

+
+	* cplus-except.c (cplus_expand_end_except): If the user gives a
+	default handler, the exception is considered caught in that
+	handler.
+	* cplus-parse.y (except_stmts): Rest of fix went here, in DEFAULT
+	case.
+
+	* cplus-decl.c (finish_decl): Don't emit cleanups twice.

+	* cplus-decl.c (finish_function): Throw away more code if we have
+	an inline function from the interface.
+
+	* cplus-class.c (add_virtual_function): Set DECL_VINDEX from the
+	virtual function which comes from the vtable shared by
+	CURRENT_CLASS_TYPE, if possibe.
+
+	* cplus-typeck.c (build_binary_op): Call `default_conversion'
+	after doing type instantiation.
+
+	* cplus-init.c (build_new): New 2.0 interpretation: `new int (10)'
+	means allocate an int, and initialize it with 10.
+
+	* cplus-init.c (emit_base_init): Completion of fix for virtual
+	function table initialization.	@@ BTW, this may now cause extra
+	virtual function table initializations.	 They will all be correct,
+	but they may also be redundant.	 GCC's optimizer doesn't know how
+	to remove even the simplest such redundancy.

+

+	(emit_delay_sequence): Always write SEQUENCE as INSN.  Many routines
+	changed to reflect this.
+	(fill_simple_delay_slots): Loop for merge point when target of jump

+	Only create label when we know we will need it.
+	Simplify unnessarily complex call to safe_from_p.
+	(expand_expr): Make new variable UNSIGNEDP and use it instead
+	of TREE_UNSIGNED (type).  Also, consistently use existing
+	variable TYPE instead of TREE_TYPE (exp) and similarly for MODE.
+
+Tue Jul 24 13:50:33 1990  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)

+
+	* jump.c (mark_modified_reg): New function.
+	(thread_jumps): Look at insns between target of first jump and the

+	Use prev_nonnote_insn instead of explicit loop.

+
+	* jump.c (thread_jumps): New function to optimize the case where one
+	conditional jump jumps to another testing the same condition.  This

+	faster.	 Also, test the first letter of each string before calling
+	the string comparison function.
+
+	* toplev.c: Add new flags FLAG_THREAD_JUMPS and FLAG_PIC.  The
+	former gives better common sub-expression elimination while the
+	latter tells the compiler to emit position-independent code.
+	(rest_of_compilation): Thread jumps if requested.
+
+	* stor-layout.c (layout_{record,union}): For loop bodies meant only
+	for FIELD_DECLs, make sure we have a FIELD_DECL before proceeding.
+
+	* stmt.c (expand_end_case): Use ADDR_DIFF_VEC if FLAG_PIC is

+	(primarily branch scheduling) after register allocation.
+
+	* local-alloc.c (local_alloc): If defined, execute
+	ORDER_REGS_FOR_LOCAL_ALLOC.
+
+	* genrecog.c (struct decision): Extended to handle DEFINE_SPLITs.
+	(write_tree): Split into three subroutines: `write_tree_1' which
+	does the main work, `write_tree' which does the original job, and
+	`write_split_tree' which builds the recognizer for insn splitting.
+	(add_to_sequence): Handle MATCH_OP_DUP.
+	(main): Bui.Build both insn->insn_code and insn->insn_list
+	recognizers.
+	Also, fixed comment at the top of the file.

+	* genoutput.c (main): Handle DEFINE_SPLIT.
+	* genconfig.c (main): Handle DEFINE_SPLIT and MATCH_OP_DUP.
+	* genattrtab.c (main): Handle DEFINE_SPLIT.
+
+	* fold-const.c (various places): Use `build1' constructor instead of
+	`build' constructor whenever possible.
+
+	* final.c (final_scan_insn): If we know the status of the condition
+	codes at a particular JUMP_INSN (by dint of the fact that it has a
+	REG_CC_STATUS note), set CC_STATUS to reflect that value.
+	(only_leaf_regs_used): @@ For some reason the frame pointer register
+	is not marked live, even when it is.  If FRAME_POINTER_NEEDED is
+	nonzero, set REGS_EVER_LIVE[FRAME_POINTER_REGNUM] to 1.
+
+	* expr.c (emit_library_call): Round ARGS_SIZE.CONSTANT up, not down.
+	Use new macro MAX to accomplish this.
+	(safe_from_p): Don't check that EXP is nonzero.	 Instead, make
+	caller check (only in one place) that argument to `safe_from_p' is
+	non-zero.
+	(expand_expr): In COND_EXPR case, make sure that the predicate is
+	safe from the two conditions.  Lossage occured in a construct of the
+	form (c = c < 0 ? d : -d).
+
+	* explow.c (plus_constant): Handle LO_SUM rtl.
+
+	* c-typeck.c (build_binary_op_nodefault): If optimizing, try merging
+	component refs and/or comparisons into larger operations.
+
+	* c-common.c (rewrite_for_merged_ref): New function.  Canonicallizes
+	expressions to be recognizable as candidates for merged
+	COMPONENT_REF operations.
+	(make_merged_ref): Builds custom FIELD_DECLs for accessing multiple
+	bits in a byte simultaneously.
+	(merge_component_comparisons): Optimize COMPONENT_REFs in
+	expressions that look like (x.p == y.p && x.q == y.q) or
+	(x.p != y.p || x.q != y.q).  Also optimize (x.p == c1 && x.q == c2),
+	where C1 and C2 are known constants.
+
+	* c-lang.c (print_lang_statistics): Added new hook function.
+	Currently does nothing for C.
+
+	* c-convert.c: Use `build1' constructor instead of `build'
+	constructor whenever possible.
+
+	* cplus-typeck.c (build_binary_op_nodefault): Call this function for
+	better applicability of the merged component ref optimization. 
+	Also, add more recognized cases.
+
+	* cplus-type2.c (merge_component_comparisons): Code improved, and
+	moved to c-common.c.
+
+	* cplus-parse.y (operator_name): Recognize `operator,'.
+	(expr): On parsing ',', call `build_x_compound_expr' instead of
+	`build_compound_expr'.

+	of a type.
+	(component_declarator0): Set CURRENT_DECLSPECS from the bitfield
+	type.
+
+	* cplus-method.c (hack_wrapper): Rename parameter TYPE to CNAME,
+	since it is a type name we pass in, not a type.
+
+	* cplus-lex.c (opname_tab): Add `operator,'.

+	declarations should be considered as having "gotten a semicolon".

+	* cplus-init.c (build_delete): Rest of changes to reimplement new
+	destructor mechanism.
+	(build_vbase_delete): Fix bug whereby arrays of length 0 and 1 were
+	not being correctly handled.  Also, where elsements were not being
+	deleted.  Use new destrouct calling convention.
+	(various places): Change TYPE_HAS_CONSTRUCTOR to
+	TREE_HAS_CONSTRUCTOR where appropriate.
+
+	* cplus-expr.c (cplus_expand_expr): Use `emit_block_move' to copy
+	data from RETURN_TARGET to CALL_TARGET in case they do not line up
+	normally.
+
+	* cplus-decl2.c (finish_file): No need to call `build_vbase_delete'
+	on top-level objects anymore, since destructors now do the right
+	thing.
+
+	* cplus-decl.c (finish_function): Implement new destructor
+	mechanism: destroy virtual baseclass objects if (in$charge & 2) is
+	nonzero.  Deallocate if (in$charge & 1) is nonzero.
+
+	* cplus-cvt.c (build_up_reference): Use TREE_HAS_CONSTRUCTOR, not
+	TYPE_HAS_CONSTRUCTOR on non-TYPE tree nodes.
+	(build_up_reference): Only build up references between compatible

+
+	* cplus-class.c (build_vbase_path): Recover from bad parse errors.
+	(build_method_call): Implement new ctor/dtor semantics to allow
+	differentiation between tearing an object down and deallocating it.

+
+	* ALL GNU C++ files: Use new macro IDENTIFIER_TYPE_VALUE to lookup
+	type value of an identifier.  Also implement related macros

+	Searches an rtx for any reference to the given register, and
+	returns the register rtx used if any.
+	(split_hard_reg_notes): New function.  Handles the case where a

+	REG_UNUSED note which mentions the same register.
+	(update_links): Add call to new function split_hard_reg_notes.
+	Correctly handle the case when the dest of the original insn was a
+	multi-word register which was split in the split insns.  In this

+	dest, if any such exists.
+
+	* unroll.c (reg_dead_after_loop): Check that a CODE_LABEL which is
+	the target of a JUMP_INSN has a non-zero PREV_INSN field before

+Tue Jun 25 07:39:29 1991  Matthew Self  (mself at next.com)
+
+	* varasm.c (const_hash, compare_constant_1, record_constant_1):
+	For ADDR_EXPR's, don't hash address of SYMBOL_REF.  Only use
+	offset and name of symbol.  This allows constructors which
+	contain pointers to identical string literals to be uniqued.
+
+	* loop.c (loop_optimize, init_loop):  Moved call to
+	gcc_obstack_init() from loop_optimize() to init_loop().
+

+
+	* reload1.c (modes_equiv_for_class_p): Only fail if registers in
+	CLASS that can hold ALLOCATE_MODE can't also hold OTHER_MODE.  Do
+	not fail for the reverse test.  ALLOCATE_MODE is always a larger

+	uses when allocating spill registers.  Rewrite comments to explain
+	new behaviour.
+	(reload): Change call to modes_equiv_for_class_p to match new
+	semantics.
+
+	* combine.c (simplify_shift_const): When simplifying (ashiftrt
+	(ashift inner_const_int) const_int), was checking the wrong number of
+	high order bits of inner_const_int.  Also correct typos in comments.
+
+	* c-convert.c (convert_to_integer): Must also check ARG1 for
+	unsignedness, because ARG0 could be a constant when EXPR is a
+	MINUS_EXPR.
+
+	* combine.c (try_combine): When splitting, it is not safe to use
+	I2DEST if it is referenced by NEWPAT.
+
+	* combine.c (distribute_notes): After converting REG_DEAD notes to
+	REG_UNUSED notes, clear PLACE if it already has a REG_UNUSED note,
+	to prevent adding a duplicate REG_UNUSED note.

+
+	* optabs.c (expand_float): Always do conversions to FMODE in the
+	signedness of the input.

+
+	* reload1.c (eliminate_regs): Copy reg_equiv_memory_loc in case
+	it is shared and we make a reload inside it.
+
+	* stupid.c (stupid_mark_refs): Registers that aren't used must die
+	in the insn after their birth so they conflict with other outputs.
+
+	* vax.md: Replace patterns to convert (and (ashiftxx))
+	into (and (rotatexx)) with the patterns that are actually made
+	by combine.
+	We can allow offsettable addresses for operand 0 and it is not
+	early-clobber.
+
+	* out-rs6000.c (secondary_reload_class): Correctly interpret result of
+	true_regnum.
+
+	* out-rs6000.c (output_toc): Write FP constants in TOC.
+	* tm-r6000.h (TARGET_FP_IN_TOC): New flag.

+
+	* cse.c (cse_set_around_loop): Fix typo in call to note_mem_written.

+	insn.
+
+	* expr.c (expand_expr, case COND_EXPR): Correctly handle X ? A : X + 1.
+	Previous change called invert_truthvalue which can modify EXP; we now
+	call it a second time to undo its action if do_store_flag fails.
+
+Sat Jun 22 02:37:59 1991  James Van Artsdalen  (james at bigtex.cactus.org)
+
+	* cse.c (cse_set_around_loop): Don't try to initialize an
+	automatic structure.

+	* reg-stack.c (compare_for_stack_reg): If both operands to a
+	compare are the same stack reg, don't process death on the second.
+
+	* i386.md (all float patterns): Don't allow constants in the
+	operand predicates.

+	dealing with line-number notes.
+	(unlink_notes): Put line-number notes in LINE_NOTE for reuse.

+	reordering is complete, restore the line-number notes as needed.
+	(schedule_insns): When debugging information is present, allocate
+	and initialize line_note and line_note_head.  After scheduling,
+	walk the insns to delete redundant line-number notes.

+
+	* old-sparc.c, out-old-sparc.c, tm-old-sparc.h: Delete obsolete
+	files.
+
+	* loop.c (loop_number_exit_labels): Expand comment.  Mention that
+	returns are not included because all bivs and givs are pseudos and
+	hence must be dead after a return.

+	table being out of range.
+	For ADDR_DIFF_VEC, return a MINUS or (truncate (minus L1 L2)).
+	(fold_rtx, case PLUS): If we have (plus X (label_ref L)), see
+	if X is equivalent to (minus L1 L2).
+	(cse_insn): Put (minus L1 L2) in `src_const' so it gets in a
+	REG_EQUAL note and gets put in the hash table.
+	If we are branching to a jump table, we are really branching to
+	immediately after the jump table
+	Remove special-case kludge for ADDR_DIFF_VEC; now handled properly.
+
+	* vax.md (casesi): Make pattern agree with machine instruction;
+	specifically, index is multiplied by two and the comparison is LEU,
+	not LE.

+
+	* sparc.md: Remove special-case shift insns which load and shift

+
+	* c-common.c (decl_attributes): Warn if requested alignment is not

+	to take effect.
+	
+	* varasm.c (assemble_variable): Warn if DECL_ALIGN is greater than

+	with correct args.
+
+	* stor-layout.c (layout_record, layout_union): Do not clamp struct

+
+	* c-parse.y (unary_expr):  When alignof is applied to an expression,
+	call c_alignof_expr so that we can check DECL_ALIGN instead of calling
+	c_alignof (TYPE_ALIGN (TREE_TYPE (expr))).
+
+	* c-typeck.c (c_alignof_expr):  New function to compute alignof for

+	* expmed.c (store_bit_field, extract_bit_field): Don't use
+	gen_highpart for multi-word fields; instead, loop and use
+	operand_subword.  We now support fields more than two words long.
+	(mask_rtx, lshift_value): Just pass high and low words to
+	immed_double_const; it will mask and choose CONST_INT vs. CONST_DOUBLE.
+	* expr.c (convert_move): Use operand_subword instead of gen_highpart.
+	Don't assume GET_MODE_SIZE (DImode) > UNITS_PER_WORD.
+	(move_block_to_reg): Add MODE arg.
+	Use operand_subword_force.

+
+	* function.c (find_replacement): New function.
+	(fixup_var_refs_insns): Pass pointer to listhead of (new)
+	fixup_replacement structures; if any entries were pseudos, copy from

+Mon Jun  3 17:19:40 1991  Michael Tiemann  (tiemann at cygint.cygnus.com)
+
+	* cplus-expr.c (decl_in_memory_p): New function.
+	* cplus-typeck.c (mark_addressable): Test `decl_in_memory_p' instead
+	of testing memory_operand, since the DECL_RTL of a decl may be a
+	(MEM ...) by not a valid memory address.
+
+	* cplus-typeck.c (mark_addressable): When we decide that a static
+	const variable must go to memory, make sure that its rtl is
+	allocated from the correct obstack.

+	* cplus-decl.c (grokdeclarator): Replace undocumented BREAK_C_TAGS
+	#define control with comments explaining why or how it is correct
+	for GNU C++ to break C's notions of what a tag is.
+
+	* cplus-call.c (convert_harshness): Replace undocumented #if
+	AMBIGUOUS_WORKING control with a comment explaining the actions
+	where this control used to be.

+
+	* tm-i386.h (TRAMPOLINE_TEMPLATE):  Changed a 040 to 0xe0;
+	this is the proper code for a jmp [%eax] instruction.

+

+	for case where I1 and I2 both feed I3.
+	(distribute_notes): Don't interpret setting a reg as a use of the
+	reg; use new reg_referenced_p and simplify code.
+
+	* flow.c (propagate_block): Ensure that LOOP_DEPTH is correct at all
+	insns in a basic block, otherwise reg_n_refs will be set incorrectly.
+
+	* recog.c (validate_replace_rtx_1): Don't change mode of memory
+	reference that is mode-dependent.
+	Don't make a MEM with a larger mode than original.
+
+	* combine.c (try_combine): Disable code to check MODES_TIEABLE_P
+	added May 20th and 22nd; this should not be needed now that
+	LIMIT_RELOAD_CLASS has been added to reload.
+
+	* flow.c (mark_set_1): Allow for the fact that stack pushes don't have
+	REG_INC notes.
+	* local-alloc.c (optimize_reg_copy): Likewise.

+
+	* reorg.c (mark_set_resources): #ifdef PUSH_ROUNDING, mark SP as always

+
+Fri May 31 16:11:57 1991  Ken Raeburn  (raeburn at watch.com)
+
+	* cplus-lex.c (process_next_inline): Set line number and filename if
+	more inline data is to be processed.
+	(store_pending_inline): Treat FUNCTION_TYPE like METHOD_TYPE.  Use
+	current_class_type instead of extracting it from method type; the
+	two should be the same, and the latter doesn't work for statics.
+
+	* cplus-decl.c (start_decl): When constructing templates, use
+	original name of function rather than "mangled" name.  Look for
+	FUNCTION_DECL, not FUNCTION_TYPE, when deciding how to push the
+	new decl.
+	(start_method): Default inlining does not apply to template
+	expansions.
+
+	* cplus-pt.c (pending_template_expansions): Moved declaration to
+	start of file.
+	(tsubst): For FUNCTION_DECL, use original name of source, not
+	mangled name.
+	(instantiate_template): Local variables now non-static.  Fill in
+	pending-inline field of new decl, rather than template-info, and
+	chain into either pending-inlines or pending-template-expansions.
+
+	* cplus-typeck.c (build_x_function_call): If a template is found,
+	treat it as an overloaded declaration.
+
+Fri May 31 14:20:45 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* Makefile.in (all.cross): New target.

+
+Fri May 31 11:43:31 1991  Matthew Self  (mself at next.com)
+
+	* tm-next.h (EXTRA_SECTION_FUNCTIONS):
+	Add new constructor and destructor sections.
+	(MAX_OFILE_ALIGNMENT): Define as 2^15 for Mach-O.
+	(ASM_OUTPUT_ALIGN): Use .align, not .even.  Allow alignments > 2.
+	(CPP_PREDEFINES): Added -Dm68k since some code expects this.
+
+Fri May 31 05:41:51 1991  Michael Tiemann  (tiemann at cygint.cygnus.com)
+
+	* cplus-class.c (pushclass): New argument value for MODIFY accepted.
+	* cplus-decl2.c (build_push_scope): Call `pushclass' with MODIFY == 3.
+
+	* cplus-decl.c (finish_function): Set TREE_PUBLIC and TREE_EXTERNAL
+	bits on functions according to #pragma interface/implementation,
+	regardless of whether or not the function's inline.  This fixes the
+	bug of needless code replication with -fno-inline.
+
+Thu May 30 17:39:53 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* expr.c (expand_expr):

+Thu May 30 17:36:45 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* cse.c (count_reg_usage, delete_dead_from_cse): New functions.
+	* toplev.c (rest_of_compilation): Call delete_dead_from_cse immediately
+	after the first cse pass.
+
+	* local-alloc.c (validate_equiv_mem_from_store, validate_equiv_mem):
+	New functions, to find cases where a REG is equivalent to a MEM.
+	(optimize_reg_copy): New function.
+	(update_equiv_regs): Call these new functions.
+	Look for a register used in only one basic block being stored into
+	memory.
+	Keep track of loop depth so we can find regs used only once, but
+	inside a loop.
+	* reload1.c (reload): Use single_set when looking for an insn
+	that initializes a register.
+	If making a REG equivalent to a MEM, the insn with SET_DEST being
+	the register isn't always the one making the equivalence, since the
+	equivalence might be occurring due to a store into MEM; in that
+	case set reg_equiv_init to the latter insn.
+
+Thu May 30 14:23:01 1991  Ken Raeburn  (raeburn at watch.com)
+
+	* Pending expansions processed at end-of-file can be processed out
+	of order, so freeing the associated data from the obstacks is not
+	possible.
+	* cplus-tree.h (struct pending_inline): New field can_free
+	indicates whether to free the text after processing it.
+	* cplus-lex.c (do_pending_inline, process_next_inline): If
+	can_free flag is set, specify inline-text obstack, otherwise null
+	pointer.
+	(cons_up_default_function): Clear flag.
+	(reinit_parse_for_method): Set it.
+	(store_pending_inline): Clear it when changing obstacks.
+	(pending_template_obstack): Deleted.  References changed to use

+
+	* cplus-lex.c (store_pending_inline): Set DECL_PENDING_INLINE_INFO
+	value after swapping obstacks, not before.
+
+Thu May 30 07:23:18 1991  Michael Tiemann  (tiemann at cygnus.com)
+
+	* va-sparc.h: Has to be a char * to be compatible with Sun.
+	i.e., we have to pass a `va_list' to vsprintf.  Also, fixed
+	bug in passing vararg structs.
+
+Thu May 30 00:32:18 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* configure: Delete Makefile.tem before writing it.

+	(DECL_TEMPLATE_INFO): Accessor macro for above.
+	(TEMPLATE_EXPANSION_NAME_P): Deleted.
+	(push_overloaded_decl_top_level): Added declaration.
+	(TEMPLATE_TYPE_TPARMLIST, TEMPLATE_TYPE_IDX,
+	TEMPLATE_TYPE_SET_INFO, TEMPLATE_CONST_TPARMLIST,
+	TEMPLATE_CONST_IDX, TEMPLATE_CONST_SET_INFO): New macros for
+	accessing fields of TEMPLATE_..._PARM nodes.
+	(struct pending_inline): New fields for names and values to bind
+	to them while processing.
+	(struct template_info): Definition moved here from cplus-pt.c.
+	(instantiate_template): Added declaration.
+	(instantiate_class_template): Ditto.
+	(processing_template_{decl,defn}): New variable declarations.
+
+	* print-tree.c (print_node): Provide missing argument to
+	print_node for `bitpos' field.  Display `virtual' flag, and (for
+	function and method types) `class' field; these are only used by
+	C++ that I'm aware of, but are defined in common code, so they
+	should be displayed here.
+
+	* cplus-parse.y (template_def): Separate set of derivations, for
+	class and function templates.  Template_def is a type of extdef;
+	extern_lang_string before template_def is not permitted.
+	(fn_tmpl_end): New nonterminal, anything that signals the end of
+	the portion of a template that we should parse.
+	(yyprint): Define only if YYDEBUG.  Handle TYPESPEC.
+	(datadef): Complain at class template override declaration if that
+	specialization has already been produced by expansion.  Template
+	definitions no longer belong here.
+	(tmpl.2): Always call instantiate_class_template; let it decide
+	whether or not to go through with it.
+	(template_instantiation): Put decl in global scope only if not
+	already there.
+	(typespec, scoped_typename): Scoped typename inside template type
+	should be a scoped_typename, not a typespec.  However, a
+	template_type should be allowed as a typespec.
+	(structsp): Don't undo template name overload here.  Deleted
+	derivation from template_type.
+	(named_class_head_sans_basetype): Don't overload template name.
+	(LC): Do it here.
+	(notype_declarator): For scoped_id derivations, don't call
+	build_push_scope if the scoped_id is a SCOPE_REF.
+	(scoped_id): Moved old typespec-from-template_type rule here.
+	Call resolve_scope_to_name only if template parms aren't involved.
+
+	* cplus-pt.c (struct template_info): Definition deleted.
+	(templates, current_template_info): Variables deleted.
+	(processing_template_{decl,defn}): New variables.
+	(push_template_decls, pop_template_decls): Accept parmlist and
+	arglist as separate arguments, instead of deriving both from the
+	template.  If class_level is non-zero, push and pop a level,
+	making it transparent to tags.  Removed some pointless checks from
+	pop_template_decls that are only needed in push_template_decls,
+	and some assertions from both.  Callers changed.
+	(uses_template_parms): Return non-zero iff argument refers to any
+	TEMPLATE_*_PARM nodes.
+	(tsubst): Walk tree, substituting for template parms, returning
+	new tree.
+	(type_unification): Rewritten a bit, to make it work.  New
+	argument nsubsts is pointer to place to record number of
+	substitutions made when matching.
+	(unify): Renamed from unify1.  Rewritten completely, to work.
+	Still may need extending for some tree node types.
+	(do_pending_expansions): At end-of-file, expand any templates not
+	yet expanded which were actually needed.  Needs work to accomodate
+	latest specs.
+	(process_template_parm): Simplified slightly.  Non-type parms
+	should be marked read-only; aggregate types are not allowed, since
+	equality checks don't work.
+	(end_template_parm_list): Moved to after process_template_parm.
+	Push a level, and push decls for TEMPLATE_*_PARMs.  Set
+	processing_template_decl flag.
+	(end_template_decl): For non-class templates, build a
+	TEMPLATE_DECL and store the regular decl in its result field.
+	Context and other values get copied over too.  Call poplevel to
+	get rid of the TEMPLATE_*_PARM decls, and call
+	dont_forget_overload to avoid losing the declaration later.  Clear
+	processing_template_decl flag.  Call get_pending_sizes, so later
+	function compilation doesn't try to evaluate sizes of templates.
+	(mangle_class_name_for_template): Convert type/non-type check from
+	switch to if test.  Added support for ENUMERAL_TYPE, REAL_TYPE,
+	and POINTER_TYPE parms.
+	(instantiate_class_template): Renamed from old
+	instantiate_template.  Don't expand if type size is set, or if
+	being-defined flag is set, or use-template flag is non-zero.  If
+	other-template parms are used in the parm list, construct a simple
+	RECORD_TYPE node and return it.  Catch case of template declared
+	but not defined before use.  Renamed argument from class to
+	classname.  Set processing_template_defn flag.
+	(instantiate_template): New routine; constructs new decl node
+	given TEMPLATE_DECL node and template arg vector.
+	(end_template_instantiation):  Set use-template field to 2 ("did
+	use template").  Clear processing_template_defn flag.
+	(reinit_parse_for_template): Get template-info ptr from decl node.
+	Store template parm vector in it.
+	(pending_template_expansions): List of templates that may need
+	expanding later for function or class data definitions.
+
+	* cplus-method.c (build_overload_value): Ensure tree code is
+	PARM_DECL.  Handle ENUMERAL_TYPE like INTEGER_TYPE.  For DImode
+	values, compare against integer_zero_node instead of constructing
+	another one.  Added support for POINTER_TYPEs.  If not
+	REAL_IS_NOT_DOUBLE, support real values as well.
+	(build_overload_name): Accept TEMPLATE_*_PARM nodes, but generate
+	a string that should cause some assembler errors.
+
+	* cplus-ptree.c (print_lang_decl): Retrieve template-info from its
+	new place.
+	(print_lang_type): For TEMPLATE_TYPE_PARM, print its (short) info
+	and return.  For RECORD_TYPE, print use-template and interface-*
+	fields.
+
+	* cplus-search.c (push_class_decls): Don't call
+	push_template_decls; the bindings of template parameter names
+	should be associated with the template body, not with the class.
+	Do overload the template name, however.
+	(pop_class_decls): Don't call pop_template_decls.
+
+	* cplus-call.c (build_method_call): Changed to recognize
+	constructor of template class.
+	(build_overload_call): Add in number of template substitutions as
+	extra cost of a candidate function.  For template decls, try
+	unification and instantiation before evaluating cost of result.
+	This too is incorrect in terms of the spec, but it's a starting
+	point for later work.
+
+	* cplus-class.c (finish_struct): If structure is named, undo
+	overload of its name as a template.
+	(pushclass): If prev_class_type was a template class, pop it; the
+	decls are handled wrong and should be re-entered.
+
+	* cplus-decl.c (poplevel): Assert that the current level is not
+	global.
+	(push_to_top_level): Include global scope when looking for old
+	values, because class bindings aren't listed in any other one
+	place.
+	(push_overloaded_decl_top_level): New function; like
+	push_overloaded_decl, but places decl in global binding level.
+	(dont_forget_overload): New function; removes decl from list of
+	overloads to be forgotten when scope is exited.
+	(start_decl): If template parms are used, construct a
+	TEMPLATE_DECL node referencing the current decl.  For function
+	templates, call push_overloaded_decl; for class template members,
+	chain them into the class template definition.
+	(grokdeclarator): Don't try determining size of a
+	TEMPLATE_CONST_PARM node.  For template class-data decls,
+	construct a phony VAR_DECL node and return it.
+
+	* cplus-decl2.c (grokfield): For static class data, use
+	build_overload_name result, instead of copying class name, since
+	the latter could be a human-readable template class name.  (If
+	NEW_OVERLOAD_SCHEME is not defined, do this only if the class has
+	a template-derived name.)
+
+	* cplus-lex.c (pending_template_obstack): New variable; obstack
+	for pending-template stuff to be saved to end-of-file.
+	(init_lex): Initialize it.
+	(default_def): New variable; used for default definition of copy
+	constructors and destructors.
+	(do_pending_inlines): Figure out whether text is in an obstack,
+	and which one, for calling feed_input.  Push template decls if
+	needed, as specified in pending_inline data.  Pass current
+	pending_inlines pointer back in PRE_PARSED_FUNCTION_DECL instead
+	of next.
+	(process_next_inline): Ditto.  Pop pending inline data if needed.
+	(store_pending_inline): New function.  Decides which obstack to
+	store a pending definition on, and which list to chain it into.
+	(reinit_parse_for_method): Call it.
+	(reinit_parse_for_block): If character passed in is '=', look for
+	a semicolon to end the block; don't require a {} block.  Don't pad
+	to 8 bytes on USG, since we aren't feeding input via stdio any
+	more.  Also, use newlines instead of # directives for advancing
+	line number only a few lines.
+	(cons_up_default_function): Punt padding for USG stdio, since we
+	aren't using it any more.  Use default_def for definition.  Call
+	store_pending_inline to save it away.
+	(identifier_type): For TEMPLATE_DECL, DECL_RESULT field non-null
+	indicates a non-type template, so don't return PTYPENAME.
+	(yylex): If end-of-file and input isn't redirected, call
+	do_pending_expansions and maybe start yylex over.  Don't check
+	TEMPLATE_EXPANSION_NAME_P; a proper name transformation system
+	will eliminate conflicts.  Try for SCOPED_TYPENAME with PTYPENAME
+	too.

+	cast is missing argument.
+
+	* cplus-tree.h (interface_unknown): Add a declaration for this
+	variable.
+
+	* cplus-type2.c (store_init_value): Normally initialized PIC data
+	must be laid into the text segment and then copied into the data
+	segment.  But cecause of special things we do for ctors and dtors
+	(the only things that can reference such things), we can leave
+	vtables in initialized data space.
+
+	* cplus-decl.c (finish_decl): Use #pragma interface knowledge if
+	available for processing initialized variables of type const.

+	All callers changed.
+	If insn stores into the same, nonvolatile, MEM as recorded in
+	last_mem_set, it is dead.
+	(mark_set_1): If writing into register mentioned in last_mem_set or
+	writing into memory, clear last_mem_set.
+	Record last MEM written.
+	(find_auto_inc): New function, from mark_used_regs.

+	(mark_used_regs, case MEM): Clear last_mem_set.
+	Call find_auto_inc; move code to there.
+	(mark_used_regs, case SET): Don't call recursively on MEM if it is
+	SET_DEST, instead call find_auto_inc ourselves.

+
+	* out-m88k.c (emit_bcnd): Use bxx when optimizing so jump_optimize

+	get_condition to find the values being compared.
+
+	* m88k.md: Don't use operand0 or operand1.

+
+	* gcc.c (process_command): Warn if -x follows last input file.
+

+	(mips_const_double_ok): Allow normal FP constants (not Infinity,
+	Nan, etc) to be used as operands when using the MIPS assembler.
+	(simple_memory_operand): Combine GP memory references from
+	gp_memory_operand.  Delete gp_memory_operand.

+	(cmp_op): Return true if comparison operator.
+	(uns_cmp_op): Return true if unsigned comparison.
+	(mips_move_1word): New name for mips_move_instructions.  Also, loads

+	define_expand, to set up block moves.  At present, unless -mmemcpy
+	is used, moves of less than 32 bytes, get straight line code, all

+	(init_cumulative_args): Take libname as third argument.
+	(function_arg_partial_nregs): Fix bug, to not return a negative
+	number when passing small structs in registers.
+	(compare_collect, compare_restore): Remove these functions, since

+	comparison operator bits.  Initialize mips_print_operand_punct to
+	return TRUE for each of the valid punctuation characters used in
+	print_operand.
+	(print_operand): %X now prints 32 bit ints in hex format.  %z now
+	prints $0 if the operand is the constant integer 0.  %(, %) now turn
+	on/off both .set noreorder/.set nomacro.  %<, %> turns on/off .set
+	nomacro.  %* turns on both .set noreorder and .set nomacro if
+	filling delay slots.  %! turns on .set nomacro if filling delay
+	slots.
+	(compute_frame_size, save_restore, function_prologue,
+	function_epilogue): Change the calling sequence of
+	compute_frame_size to save everything in a global structure, which
+	has an initialized field to indicate that compute_frame_size needs
+	to be called.
+	(function_prologue): INIT_CUMULATIVE_ARGS now takes 3 args.
+	(function_epilogue): If current_function_epilogue_delay_list is
+	non-null, use that to fill the final delay slot.  Also, make sure
+	the various asm .set's are reset properly.  Write interesting

+	(mips_epilogue_delay_slots): New function to return # of delay slots
+	the epilogue needs.
+	(null_epilogue):  Return true if the function has a null epilogue,

+	change some names.
+	(mode attribute): New attribute to describe the insn's result mode.

+	1 word instructions, 'R' for multiword instructions.
+	(unnamed patterns): Provide names for all patterns, so that -dp will
+	pinpoint exactly which pattern is used.
+	(*divsi3, *divmodsi4, *modsi3): If optimizing and not -mdebugc, use
+	the *divmodsi4 patterns, so that the opimizer will only use 1 divide
+	if doing a = b / c; d = b % c;  This replaces the peepholes, which
+	previously were used for this.  If not optimizing, use the normal
+	div/mod patterns.
+	(zero_extendqihi2, extendqihi2): Allow zero/sign extending from
+	memory.
+	(fixuns_trunc{df,sf}si2): Use generator patterns to generate

+	(negsi2): Change to a define_expand, which uses minus.
+	(one_cmpsli2): Change to a define_expand, which use the nor pattern.
+	(cmp*, b*): Redo comparison/branch completely to save things in
+	global variables, call the common C code to expand the branch, and
+	provide match_operators to do the actual branch.
+	(s*): Provide for the ability to set a register with an integer
+	comparison, without using a branch.
+
+	* make-decrose (AUX_OUTPUT2): Delete macro, since aux-output.c is
+	always compiled separately now.
+	(LANGUAGES): Suppress G++, Objc temporarily.
+	(cse.o): Rebuild cse if the config files change, to get new cost
+	functions, no longer rebuild calls/function since the FUNCTION_ARG
+	macros just call functions in out-mips.c.
+	(SRCS): Change $(AUX_OUTPUT2_SRC) to aux-output.c.
+
+	* make-mips (AUX_OUTPUT2): Delete macro, since aux-output.c is

+	(mips-tfile): Rules to build mips-tfile.
+	(mips-tdump): Rules to build mips-tdump.
+	(LANGUAGES): Suppress G++, Objc temporarily, build mips-tfile.
+
+	* mips-tfile.c (whole file): New file to put the MIPS specific debug
+	information into the object file, after the assembler has been run.
+	This is needed because the MIPS assembler provides no method of
+	setting up the debug information for local variables.  This is
+	enabled by the make-mips Makefile modifier.
+
+	* mips-tdump.c (whole file): New file to dump the contents of the
+	MIPS ECOFF symbol table in a symbolic format.  This is not currently
+	built by default, but make-mips contains rules to build it.

+
+	* tm-sparc.h (GO_IF_LEGITIMATE_ADDRESS): Don't accept a SYMBOL_REF
+	sum if FLAG_PIC is not 1.  This forces the -fPIC to take effect,
+	even when the optimizer knows how to stitch together HIGH and LO_SUM
+	combinations.
+	(PRINT_OPERAND): Move body to out-sparc.c.
+	* out-sparc.c (print_operand): New function, implementing actions of
+	old PRINT_OPERAND macro.  Comments written for all cases.

+	was completely backward.
+
+	* dbxout.c, cplus-dbxout.c (dbxout_parms): Also test that TREE_TYPE

+
+	* cplus-init.c (build_up_reference): Check FLAGS parameter to see if

+	temporary.
+	(various places): Change calls to `build_up_reference' that used to
+	use an explicit `1' to use LOOKUP_PROTECT instead.
+	(build_offset_ref): Use IDENTIFIER_TYPE_VALUE macro to the the type
+	associated with CNAME.
+
+	* cplus-class.c (build_vbase_path): Fix 11 May change by only
+	changing TREE_TYPE (EXPR) if NULL_EXPR.  We might build different
+	vbase paths for the same expr in multiple inheritance
+	initialization.
+
+	* Makefile.in: Change sed script so it matches '^# ' instead of just
+	'^#'.  This allows processing of md files with #if/#endif controls

+
+	* stmt.c (warn_if_unused_value): Don't warn about EXIT_EXPRs.

+	* cplus-search.c, cplus-xref.c: Likewise.
+	* cplus-class.c (prev_class_type): Not static; defined in cplus-tree.h.
+	* cplus-decl.c (builtin_function, auto_function): Don't put & in
+	front of function name.

+
+Sun May 26 22:47:35 1991  Michael Tiemann  (tiemann at cygint.cygnus.com)
+
+	* cplus-decl.c (make_temporary_for_reference): New function.  Split
+	out code from `grok_reference_init' so we could call it in two
+	places: where it was called before, and when initializing a
+	reference through a constructor for a temporary.
+	(grokdeclarator): Give error message instead of aborting if user
+	gave method qualifiers for function decl.
+	(start_function): Switch to temporary obstack before computing
+	destructor and constructor labels, and before building the
+	function's RESULT_DECL.
+
+	* cplus-decl.c (store_parm_decls): Make a cleanup that controls the
+	action of the garbage collector.  This ensures that the call to
+	__gc_pop doesn't get skipped in the function issues a return stmt.
+	* cplus-gc.c (expand_gc_prologue_and_epilogue): Work with new
+	cleanup model.
+
+	* cplus-gc.c (build_i_desc): Figure out whether the i_desc should

+
+	* expr.c (force_operand): When calling recursively, use
+	a temporary to force evaluation of calls.  The C language

+
+	* reload1.c (choose_reload_regs): Process reload in first pass if
+	a subsequent reload requires fewer registers.
+	Change criteria for processing from being a strict superset to

+
+	* local-alloc.c (qty_compare, qty_compare_1): Make priority function
+	the same as in global-alloc: quantities with shorter lives are
+	allocated first.  This can speed up some code by a factor of three.

+
+	* reload1.c (emit_reload_insns): Fix some minor bugs in making

+
+	* tm-next.h (EXTRA_FORMAT_FUNCTIONS): Fix typo.

+

+
+	* reload.c (find_reloads): Pre-compute preferred classes for each

+	REJECT is now only 1/3 as costly as LOSERS; ? adds 3 to REJECT so
+	that it's semantics don't change.
+
+	* expr.c (compare_from_rtx): Do EQ and NE comparisons unsigned since
+	they are usually cheaper and will cse with comparisons against zero
+	which are already unsigned.
+
+	* reload1.c (choose_reload_regs): Don't try to access reload_out
+	for disabled reload (reload_strict_low may not have been cleared).
+
+	* reload1.c (choose_reload_regs): Don't let optional reloads inherit
+	spill regs until all non-optional reloads have been allocated spill
+	regs.
+	We can use find_equiv_reg even if must_reuse, we just can't get a

+
+	* expr.c (do_tablejump): When using LABEL_REF in arithmetic, make it
+	in Pmode instead of VOIDmode.
+
+	* function.c (fixup_var_refs_1): Don't try to make paradoxical

+
+	* jump.c (find_cross_jump): Fixed 18 May change to use

+	Don't use CC0; add CCUNSmode and CCFPmode.
+	(FIXED_REGISTERS): r31 (fp) is no longer fixed.
+	(REG_CLASS_FROM_LETTER): Remove 'd' for GENERAL_REGS; 'r' already
+	means this.
+	(CONST_DOUBLE_OK_FOR_LETTER): If we can move a constant in two insns

+	(LEGITIMATE_CONSTANT_P): Always return 1.
+	(FIXUNS_TRUNC_LIKE_FIX_TRUNC): Do not define.
+	* rs6000.md: Don't use CC0; instead use a pseudo which will be assigned

+	Delete "cc" attribute and add "type" attribute.
+	Define delays for cc-setting insns and for loads.
+	Replace `d' constraint with `r'.
+	Delete patterns for HImode and QImode arithmetic operations.
+	Handle putting "easy" DFmode or SFmode constant into a register.
+	Rework compare and branches; add scc insns.
+	Fix up decrement-and-branch insns, but they still won't be used yet.
+	(call insns): Use pseudo for "lr" in indirect calls.
+	(movdf, movsf): Explictly handle need to use memory to copy between
+	general and FP registers.

+
+Sat May 18 03:51:06 1991  Michael Tiemann  (tiemann at cygint.cygnus.com)
+
+	* cse.c (FIXED_BASE_PLUS_P): Since this is used when called from
+	`expand_inline_function', also catch the case where the base
+	register is VIRTUAL_STACK_VARS_RTX.
+	(simplify_binary_operation): In EQ and NE case, convert a COMPARE
+	operand to something we can optimize.
+	(refers_to_mem_p): Handle the case when `base' is a LO_SUM.
+	* integrate.c (FIXED_BASE_PLUS_P): Define this to recognize offsets
+	from the various virtual registers.
+	(expand_inline_function): Expand exprs using EXPAND_SUM so as to get
+	stack frame addresses instead of pseudos.  This yields much better
+	cse (at little cost) for GNU C++.  Also, test FIXED_BASE_PLUS_P as
+	an alternative to CONSTANT_P to record a known register value.
+	* jump.c (find_cross_jump): If we are processing a cross jump and
+	the insns fail to match, try looking for a REG_EQUAL note that makes
+	them equivalent insns.  If found, keep going.  This is important for
+	merging cleanup codes when one cleanup path gets frame address in a
+	register when the other path gets the frame address explicitly.
+
+	* cplus-init.c (build_delete): Fixed residual use of 1-based
+	indexing to use 0-based indexing instead.
+
+	* cplus-decl2.c (grokclassfn): Fix raeburn's May 12 change so that
+	destructors still have the same name.
+
+	* cplus-decl.c (decls_match): Remove dependence on MERGED.

+	* cplus-class.c (build_vbase_path): Fixed bug in computing offsets
+	for exprs which are FIXED_TYPE_P.
+	(build_vfn_ref): Change initializer for REF from 0 to NULL_TREE.
+
+	* cplus-decl.c (maybe_build_cleanup): Add LOOKUP_NONVIRTUAL to flags
+	argument in call to `build_delete' if DECL does not use virtual
+	baseclasses.  If it does, we go through a function call to save
+	space, unless FLAG_EXPENSIVEO_OPTIMIZATIONS is nonzero.  ??Better
+	approach is to know, in expand_cleanups, to clear `flag_no_inline'
+	during the cleanup's expansion.
+
+	* cplus-*.c (various places): Add LOOKUP_DESTRUCTOR to all places
+	where we know we are calling a destructor for a non-null object.
+
+	* stmt.c (fixup_gotos): Run destructors on cleanups that come
+	from the block being exited, in addition to any inner blocks
+	for which LABEL is now defined.
+	(expand_return): Take care of destructors that occur in the
+	current binding level.
+	(fixup_cleanups): If we emitted no insns, don't change *BEFORE_JUMP.
+
+	* rtlanal.c: Define `target_flags' here...
+	* toplev.c: ...not here.  This enables us to link gen* programs
+	which might, through rtlanal.o, pull in references to `target_flags'
+	that are never used.
+
+	* function.c: Add declaration for `current_function_uses_const_pool'.
+	* expr.h: Add extern declaration for that variable.
+	* function.h (struct function): Add a slot named
+	`uses_const_pool' for `current_function_uses_const_pool'.
+	* function.c ({push,pop}_function_context): save and restore the
+	value of `current_function_uses_const_pool'.
+	* rtl.h (FUNCTION_FLAGS_USES_CONST_POOL): Defined to be 0200.
+	* integrate.c (initialize_for_inline):
+	FUNCTION_FLAGS_USES_CONST_POOL now contributes to the value of
+	`function_flags'.
+	(output_inline_function): Restore `current_function_uses_const_pool'
+	from `function_flags'.
+	(save_for_inline_copying): Only call `save_constants' if
+	`current_function_uses_const_pool' is nonzero.
+	(save_for_inline_nocopy): Ditto.
+	(save_constants): Tweaked to perform its treewalk faster.  Notably,
+	it no longer accepts ptrs to NULL rtl.  All callers changed.
+	* varasm.c (force_const_mem): Set `current_function_uses_const_pool'
+	if we create a constant pool reference.
+
+	* cplus-parse.y, c-parse.y: Add new function `set_yydebug'.  If
+	YYDEBUG is defined, sets `yydebug' to VALUE.  Otherwise, prints
+	warning that operation is invalid.
+	* toplev.c (main): Call `set_yydebug' instead of setting `yydebug'
+	directly.  This allows user to turn YYDEBUG off for faster parsing.
+
+	* cse.c (simplify_binary_operation): Eliminate abort when passed
+	DImode operands.
+
+Fri May 17 21:56:41 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)

+
+	(maybe_build_cleanup): Don't call `convert_force' on the return

+	problematic on some machines (i.e. MIPS).
+
+	* cplus-init.c (init_vfields): Use TREE_TYPE (VFIELDS) to find the
+	type for which the VFIELD was last distinguished.  This picks up

+
+	* expmed.c (synth_mult): Make it handle t == 0. Improve comments.
+	Use (max_cost <= add_cost) instead of (max_cost < add_cost) to
+	determine if we should fail early (to better prune the search).  
+	Remove loop with n from factor synthesis.  Remove -2 bias from m
+	loop (for clearity).  Add code to use load-effective-address
+	instructions.  Use bit-fiddling instead of loop to determine q in
+	the last synthesis case.

+	(build_vbase_path): Test NONNULL to decide whether a COND_EXPR is
+	actually needed.
+	(finish_struct): Another sort of hard virtual function to deal with
+	is one which comes from the non-leftmost baseclass, and who's index
+	is different between that class and the main derived class.  Use new
+	variable DOING_HARD_VIRTUALS to control when we punt and when we
+	plow through.
+	(modify_vtable_entry): If we find at this point that we have a hard

+	we'll have to rewrite this to actually use it.
+
+	* cplus-gc.c (type_needs_gc_entry): Don't need a GC entry for
+	ERROR_MARK_NODE.
+
+	* cplus-init.c (build_new): Set TREE_CALLS_NEW on RTL_EXPR.  This
+	gives us a case that `fixed_type_p' can grok.
+
+	* cplus-lex.c (identifier_type): Make this __inline if compiling
+	with GNU C.
+	(tree_node_kinds): Renamed to `tree_node_counts'.
+
+	* cplus-parse.y (various places): Take advantage of default rule

+	(finish_decl): Don't crash if TYPE is error_mark_node.
+
+	* fold-const.c (split_tree): When splitting the tree, don't call

+	conversion of one pointer type to another can cause the pointer's
+	value to change.
+
+	* tree.c (get_identifier): Speed up `get_identifier' by about a
+	factor of 2.  This becomes noticable with the long names used for
+	C++ overloading.
+	(tree_cons): Make this most frequent user of `make_node' perform its
+	actions inline.
+
+	* calls.c (expand_call): Eliminate many (most) calls to strcmp by

+
+	* cse.c (simplify_binary_operation): Remove obsolete code to convert
+	negative shift counts to the opposite shift.
+	Don't fold invalid shifts since they may trap (e.g., on Vax).

+	arithmetic simplifications.
+
+	* expr.c (do_jump): ADDRESS_EXPR is not always zero, unfortunately.
+

+	now that we know they can occur.
+
+	* reload.c (decompose): Handle SCRATCH; it can't conflict with

+	* output.h: No longer need to define operand-predicate functions.
+	* configure: (m88k/dg): Only difference between xm-m88k{,dgux}.h was
+	definition of SEPARATE_AUX_OUTPUT, so we don't need xm-m88kdgux.h.
+	* xm-m88kdgux.h: Deleted.
+	Fix typo setting `target' in Makefile.
+	* Makefile.in (AUX_OUTPUT2): Deleted.
+	(OBJS): Remove AUX_OUTPUT2 and add aux-output.o.
+	(aux-output2.o): Now aux-output.o.
+	(insn-output.o): No longer depends on aux-output.c.
+	* make-m88kdgux (AUX_OUTPUT2): No longer define.
+	* tm-m68k.h, tm-romp.h, tm-sparc.h: Define functions in out-*.c and
+	used by insn-output.c.
+	* tm-m88k.h: Remove conditionalization for SEPARATE_AUX_OUTPUT; now

+	No longer define predicate functions; done by genoutput.c.
+	* tm-mips.h: No longer define SEPARATE_AUX_OUTPUT.
+	* out-*.c: Add includes previously present in insn-output.c.

+
+Fri May  3 01:05:44 1991  Micheal Tiemann  (tiemann at pogo.gnu.ai.mit.edu)
+
+	* sdbout.c (sdbout_one_type): TYPE_FIELDs may contain other kinds of
+	_DECL nodes than just FIELD_DECL nodes (in GNU C++, at least).
+	Don't look through such nodes until further mods are made to handle
+	them better.
+
+Thu May  2 14:43:48 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

+
+	* cccp.c (hack_vms_include_specification): Modified conversion of
+	unix filenames to VMS filenames, if no VMS device or directory is
+	present, and a unix style directory name is present, then use the
+	first unix directory name as the VMS device spec. This is only
+	used in '#include <...>' type includes, when the include file has
+	not been found in the standard locations.
+
+Thu May  2 10:06:47 1991  Micheal Tiemann  (tiemann at pogo.gnu.ai.mit.edu)
+
+	* cplus-decl.c (init_decl_processing): Call init_gc_processing if
+	-fgc is requested.
+	* cplus-init.c (build_new): Argument to build_compound_expr must be
+	a TREE_LIST all the way.  The last elt of the chain cannot be an
+	_EXPR.
+

+
+	* expr.c (expand_expr, case CONVERT_EXPR): Pass bitsize to store_field

+
+Wed May  1 08:04:44 1991  Michael Tiemann  (tiemann at cygnus.com)
+
+	* Makefile.in: Handle new cplus-*.c files.
+
+	* cplus-typeck.c (common_base_type): Make this function recursive.
+	(build_component_ref): Test whether or not a FIELD_DECL, not whether
+	or not a VAR_DECL||CONST_DECL||TYPE_DECL.
+
+	* cplus-parse.y: Fixed grammar so that template type decls could be
+	used.  Previously, support existed for template decls following
+	types, but not as types.
+	* cplus-pt.c ({push,pop}_template_decls): New functions.
+	(instantiate_template): Call `push_template_decls'.
+	(end_template_instantiation): Let `poplevel' restore old bindings.
+	No need to clear out extra stuff.
+	(pushclass, popclass): Call `{push,pop}_template_decls' if the class
+	we are pushing or popping has template arguments.  These arguments
+	go at class level.
+
+	* cplus-method.c (build_opfncall): Test TRY_SECOND before testing
+	possibly uninitialized XARG2.
+
+	* cplus-lex.c (init_lex): Initialize NODE_TABLE, OPNAME_TAB and
+	ASSIGNOP_TAB to hold zero.  Since these come from malloc'd memory,
+	we cannot trust them to be initialized on startup.
+
+	* cplus-init.c (expand_aggr_init_1): When initializing through a
+	TARGET_EXPR for objects of the same type (e.g., X a = X (10);)
+	use EXP's DECL_RTL as the DECL_RTL of the TARGET_EXPR.
+
+	* cplus-decl2.c (finish_file): Handle new flag `-fgnu-binutils'.
+	When zero, don't use GNU extensions to a.out format.  ???Should be
+	merged into varasm.c.
+
+	* cplus-class.c: Added support for `dossiers'.  This support is
+	implemented by extending the virtual function table and by giving
+	all C++ objects a virtual function table to hold it's dossier.
+	* cplus-decl.c (record_builtin_type): New function to construct
+	dossier information for built-in types.
+	(output_builtin_tdesc_entries): To keep repeated information under
+	control, we only output this information for the file that contains
+	`main'.
+	(init_decl_processing): Many dossier-related changes.	
+	(init_lex): Recognize new reserved words `headof' and `classof' if
+	-fgc.
+	* cplus-parse.y: Grammar now recognizes `headof' and `classof'
+	expressions.
+	* cplus-method.c: Added dossier constructors here.
+	* cplus-tree.h (CLASSTYPE_DOSSIER): New macro: `dossier' is a new
+	field in lang_type.
+	* cplus-typeck.c (convert_for_assignment): Handle
+	`class_star_type_node'.
+
+	* cplus-class.c: New variable current_class_depth.  Used to tell
+	what class nesting level the compiler is at.
+	* cplus-decl.c (grokdeclarator): Now supports references to decls
+	that come from nested types.  For example, int foo::bar (foo_tag);
+	where `foo_tag' is a tag that comes from foo.  Previously this was
+	supported only as int foo::bar (foo::foo_tag);
+	* cplus-decl2.c (build_push_scope): build a SCOPE_REF node while
+	pushing into the context for the scope.  When `grokdeclarator' sees
+	one of these nodes (distinuished by its TREE_COMPLEXITY being set to
+	the current_class_depth), it processes the decl and pops the scope.
+
+	* cplus-class.c (build_vbase_path): Trust objects that are
+	`fixed_type_p'.  Also, don't assume an object is non-null unless
+	flag says this is explicitly so.  InterViews creates and may
+	manipulate (via delete) lots of null objects.
+	(build_vfn_reference): Use IS_AGGR_TYPE test on type, not in
+	INSTANCE.
+	(resolves_to_fixed_type_p): New argument NONNULL is used in case we
+	know and object to be non-zero.  All callers changed.
+
+	* cplus-call.c: New file, from file cplus-class.c.  Contains code to
+	generate method calls.
+ 	* cplus-class.h: New file, contains common declarations for
+	cplus-class.c and cplus-call.c.
+
+	* cplus-class.c (finish_struct_bits): Don't leave last_conversions
+	uninitialized.
+
+Tue Apr 30 17:14:00 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

+
+	* tm-decstatn.h (CPP_PREDEFINES): Define __mips and __LANGUAGE_C.
+
+	* explow.c (allocate_dynamic_stack_space): Compensate if
+	STACK_POINTER_OFFSET throws off the alignment.
+
+	* loop.c (strength_reduce): Typos setting not_every_iteration.

+
+	* varasm.c (output_addressed_constants): Return and indication of
+	whether the variable requires link-time relocations.
+	(assemble_variable, get_or_assign_label): Use this value when
+	choosing the section.  Use the data section for variables and
+	constants that are otherwise read-only when -fpic is given and
+	when link-time relocations are required.
+	* tm-*.h (SELECT_SECTION): Accept a new second parameter RELOC.
+
+Tue Apr 30 10:24:36 1991  Tom Wood  (wood at dg-rtp.dg.com)
+
+	* rtl.h (NOTE_INSN_LOOP_VTOP), rtl.c (note_insn_name): Add a new
+	note indicating the virtual top of a loop.
+	* jump.c (duplicate_loop_exit_test): Mark the duplicated exit code
+	in the loop as the virtual top of the converted loop.
+	(squeeze_notes): Move loop-vtop notes as well.
+	* loop.c (scan_loop): When a loop-vtop note is encountered, reset
+	`maybe_never' and `call_passed'.
+	(strength_reduce): Similarly, reset `not_every_iteration'.
+
+Tue Apr 30 08:15:50 1991  Michael Meissner  (meissner at osf.org)
+
+	* expr.c (do_store_flag): Move the join label after setting the
+	target value to 0, rather than before, which generates code that
+	always stores 0 into the target if the machine does not have a
+	builtin scc operation.
+
+Tue Apr 30 06:26:36 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* reload1.c (reload): When making reg_equiv_mem and reg_equiv_address
+	from reg_equiv_memory_loc, clear the one we aren't setting; it might
+	have been previously set.
+
+	* final.c (final_scan_insn): Correctly handle when the first insn in a
+	SEQUENCE is a JUMP_INSN that forces restoration of a comparison
+	previously thought unnecessary.
+
+	* fold-const.c (fold, case PLUS_EXPR): If we have 2 * real_cst, 
+	fold into a new constant instead of making real_cst + real_cst.
+

+	(resolve_scope_to_name): Look at fields of current type as well as
+	tags, in case of local typedefs.

+	for lexer to recognize.
+	cplus-lex.c (yylex): Turn it into END_OF_SAVED_INPUT.
+	(process_next_inline): Require it after inline function body.
+
+	* cplus-lex.c (do_pending_inlines): Don't save away current
+	file/line-no info; character input processing should do that.
+	(yyungetc): Turn conditional abort into assertion test.
+	(note_list_got_semicolon): Since variable "type" is available, use
+	it rather than recompute.

+
+	* cplus-parse.y (temporary_scope): New variable.
+	(object and scoped_id actions): Set it to current type.
+	(many other actions): Clear it.
+	(scoped_typename): Now derivable also from scoped_id and TYPENAME.
+	cplus-lex.c (yylex): If temporary_scope is set, use it to
+	determine type of current token being examined, instead of looking
+	always in the global scope.  (Can't properly do nested template
+	classes otherwise.)
+
+	* cplus-ptree.c (print_lang_decl): Print out template-info,
+	original-name, decl-main-variant, and pending-inline-info nodes if
+	not null.
+
+	* cplus-pt.c (mangle_class_name_for_template): For negative
+	numbers, use "m" prefix rather than printf's "-".
+	(overload_template_name): Test more assertions.  Use
+	SET_IDENTIFIER_TYPE_VALUE macro.
+	(lookup_template_class): Assert template decl node is non-null.
+	Push to permanent obstacks for new allocations.
+	(instantiate_template): Return new class type in a list.
+
+	* cplus-pt.c (undo_template_name_overload): Clear type local
+	definition of template name.

+	cplus-parse.y (structsp actions): Ditto.
+	(named_class_head_sans_basetype): Don't call
+	overload_template_name here.
+	(named_class_head): Call xref_tag, to define a tag, before calling
+	it here.

+	they have no values.
+	(yyprint, YYPRINT): New function and macro to work with debugging
+	code added to bison.

+	(template_instantiation): Call overload_template_name right away.
+	(primary -> .scope new '(' typename ')' '[' ...): Detect and warn
+	about this construct, which appears to be recognizeable, though
+	disallowed by the ARM.
+	(primary -> delete[]): Return error_mark_node.
+	(primary -> obj TYPESPEC::~TYPESPEC()): Catch, parse as valid.
+	Returned value not determined yet.
+	(typespec): No longer derived from PTYPENAME.
+	(LC): Added missing semicolon at end of rule.

+
+	* loop.c (scan_loop): When see a REG_EQUAL note, check for both
+	the move_insn and the REG_RETVAL case, since they can occur together.
+	(move_movables): For the move_insn case, handle library calls just
+	like the older normal case code below, that is, skip to the end of a
+	library call when when see a REG_LIBCALL note, and delete an entire
+	library call if when see a REG_RETVAL note.
+
+Mon Apr 29 12:58:19 1991  Jim Wilson  (wilson at cygnus.com)
+
+	* sched.c: (schedule_block): Rewrite code that computes which
+	registers are live at the end of the block.  Compute this from
+	basic_block_live_at_start info of current block, instead of from
+	all reachable blocks.  Previous code failed if one of the
+	reachable blocks consisted of dead code.
+	(sched_note_set): Set bb_live_regs when DEATH is false.
+
+	* sched.c: Update copyright.  Correct various problems with
+	indentation and white space.

+	(find_symbolic_term): New function.  Recursively search an rtx for
+	a SYMBOL_REF or a LABEL_REF and return pointer to one if found.
+	(memrefs_conflict_p): No longer needs to call canon_rtx on
+	operands of a plus.  Now handles case of two addresses with

+	(redirect_tablejump): Likewise.

+	* cplus-tree.h (DECL_GC_OFFEST): New macro for gc.
+	* cplus-tree.h: Rearrange CLASSTYPE_ASSOC and CLASSTYPE_BASETYPES so
+	that the former now uses TYPE_LANG_SPECIFIC storage, and the latter
+	uses TYPE_BASETYPES.
+	* cplus-tree.h: Change overload names of new and delete to `nw' and
+	`dl'.  Formerly, `new' was being seen as `ne', the encoding for `not
+	equal'.
+

+	cross-reference information such as a class browser or program
+	analyzer would use.
+
+	* cplus-gc.c: New file.  Add support for garbage collection.
+	* cplus-decl.c (finish_decl): Tie decls to their places in the
+	garbage collector.

+	reg_or_nonsymb_mem_operand and constraint `m' in place of `Q'.

+	* m88k.md (symbolic store patterns): These patterns are all
+	unnecessary and are deleted.
+	* out-m88k.c (emit_move_sequence): Eliminate the case that

+	patterns, but isn't needed.
+	(symbolic_memory_operand): Delete, no longer used.
+	(output_prologue): Don't check for suspicious register elimination
+	changes.
+	* tm-m88k.h (GO_IF_LEGITIMATE_ADDRESS): Treat the frame pointer

+
+Tue Apr 23 15:08:03 1991  Jim Wilson  (wilson at cygnus.com)
+
+	* out-sparc.c (output_scc_insn): Clean up and expand comments.
+	Don't assume that JUMP_LABEL fields are always valid, they aren't
+	when compiling without optimization.
+
+Mon Apr 22 13:56:43 1991  Michael Tiemann  (tiemann at cygnus.com)
+
+	* cplus-class.c (prepare_fresh_vtable): Thoroughly update virtual
+	function tables that come from baseclasses to contain the latest
+	overrides from derived classes.  This was done (in a different way)
+	for virtual baseclasses, but left undone for non-virtual
+	baseclasses.
+	(finish_struct_bits): Use assoc lists instead of class basetype list
+	to walk through the classes base classes.  This gives us more
+	relavant classes to check against.
+	* cplus-init.c (init_vfields): New function to recursively walk
+	objects and make sure their vfields are initialized.
+	* cplus-init.c (emit_base_init): Call `init_vfields' from top level.

+	* cplus-cvt.c (various places): Ditto.
+
+	* cplus-class.c (finish_struct): Add TYPE_DECLs to the list of a

+	inline', don't give it global visibility, regardless of what #pragma
+	interface/implementation suggests.
+
+	* cplus-decl.c (finish_function): ??? Questionable change for PIC:
+	don't let constructors and destructors that manipulate vtables go
+	inline, since this somehow reduces page sharing.  Really???
+
+	* cplus-except.c (init_exception_processing): Use `pushdecl' to
+	install global info that this function sets up.  That way later
+	decls can override this info (such as with an inline function).
+
+	* cplus-init.c (build_vec_delete): Set TREE_SIDE_EFFECTS of
+	controller.  Otherwise the loop won't execute.
+
+	* cplus-method.c (prepare_inline): Rewritten and simplified.

+
+	* cplus-tree.c (lang_output_debug_info): Only output nested type if
+	we would also output enclosing type.
+
+	* cplus-typekc.c (c_expand_return): Use pseudo for intermediate
+	return value if necessary.  GCC can't read the function return
+	registers in an inline functino when the return value is being
+	ignored.

+	* sched.c (sched_analyze_2): Don't recurse on constant rtx's.
+	This is necessary so that the cc0_rtx in CONST_DOUBLEs won't be seen.
+	(sched_analyze): Call sched_analyze_insn for JUMP_INSNS	also, so
+	that cc0 users will get an automatic dependence on their previous
+	insn.
+	(launch_links): Ifdef out special treatment of insns which set the
+	condition codes.  This is obsolete, and was SPARC specific anyways.
+	(new_sometimes_live): Clarify code that aborts if regno is greater
+	than max_regno.
+	(schedule_block): If the last insn sets cc0, then it must always
+	be left	in place.

+	CLOBBER in an insn created by splitting needs a REG_DEAD or
+	REG_UNUSED note added.
+	(update_links): Ignore REG_EQUIV and REG_EQUAL notes on insns that
+	have more than one set.  Generalize flow analysis of the sets in
+	the new insns so that it can handle new insns which have multiple

+	use \'s to make proper multi-line macro definition.
+
+Thu Apr 18 13:40:01 1991  Jim Wilson  (wilson at cygnus.com)
+
+	* loop.c (check_dbra_loop): Reenable no_use_except_for_counting code
+	which was mistakenly ifdefed out as buggy.  The actual bug was in

+
+	* local-alloc.c (block_alloc): Handle case where the last insn of
+	a REG_NO_CONFLICT block requires some CLOBBERs, but is a single SET.
+
+	* out-romp.c, out-rs6000.c (next_insn_tests_no_unsigned): If a
+	REG_UNUSED note for (cc0) is present on INSN, return 1.
+
+	* jump.c (delete_jump): If the previous insn sets cc0 but we can't
+	delete it for some reason, add a REG_UNUSED note for cc0 in that insn.
+
+	* out-a29k.c: Rename input_operand to in_operand and output_operand
+	to out_operand to avoid conflict with output_operand in final.c.
+	* a29k.md: Likewise.
+	(call patterns): Don't put SYMBOL_REF in MEM for recursive call;
+	it might not be recursive if inlined; let cse do it later.
+	* tm-a29k.h (RTX_COST, ADDRESS_COST): All addresses have the same
+	cost, but MEM is expensive.
+

+	error message, otherwise set up mips_reg_names.  Set up the
+	mips_rtx_classify array.
+	(print_options): New function instead of a long macro.  Add %C to
+	print part of the opcode for a branch condition, %N to print the

+	(ENCODE_SEGMENT_INFO): New macro, set SYMBOL_REF_FLAG (ie, volatil)
+	if refering to an item via the gp pointer.

+	(ADDITIONAL_REGISTER_NAMES): Define both names for the gp registers,
+	so people can use either $r4 or a0 in asm statements.

+
+Tue Apr 16 15:00:51 1991  Jim Wilson  (wilson at cygnus.com)
+
+	* unroll.c (final_giv_value): Use expand_binop instead of
+	gen_sub2_insn when emitting subtract insns, since expand_binop
+	will work for any operands.
+
+	* sched.c (schedule_insns): Don't split no-op moves; doing so
+	breaks the code that handles REG_NO_CONFLICT blocks.
+	(update_links): Delete the code that prints a warning for
+	REG_EQUAL notes where the original dest can't be found.  This no
+	longer occurs because of the above change.
+
+	* sched.c: Generalize memory aliasing code so that it will work on
+	non-RISC machines.  Instead of saving just the insn on the pending
+	lists, now saves both the insn and the mem rtx.  Old variables
+	pending_read and pending_write replaced with pending_read_insns,
+	pending_read_mems, pending_write_insns, and pending_write_mems.
+	(read_dependence, true_dependence, anti_dependence,
+	output_dependence): Now passed a MEM rtx instead of a PATtern.
+	(add_insn_mem_dependence): New function.  Adds an insn and a mem

+	(schedule_insns): Likewise.
+
+Tue Apr 16 12:31:07 1991  Jeffrey A. Law  (law at mole.gnu.ai.mit.edu)
+
+	* Makefile.in (install-man): Look for protoize.1 and unprotoize.1
+	in the current directory, not $(srcdir)
+	(install-headers): Use basename to strip off $(srcdir) from 
+	include files when installing and changing mode.

+	* rs6000.md (extendqixi2): Add CLOBBER to the first SET as well as
+	the second.
+	(load_multiple): Fix typo in operand number and add newline.
+
+	* reload.c (find_reloads_address_1): Pass actual location of a
+	MEM used in an address; also handle the case when the MEM was
+	copied.  Ensure we reload the copy, not the original address.
+
+	* reload1.c (eliminate_regs, case {INSN,EXPR}_LIST): Correctly handle
+	the cases when one or more operations is (nil).
+
+	* local-alloc.c (block_alloc): Check for REG_EQUAL on list insn
+	of REG_NO_CLOBBER sequence, not first.
+	(no_conflict_p): Set LAST and use INSN instead of P for loop start.
+
+Mon Apr 15 12:55:12 1991  Jim Wilson  (wilson at cygnus.com)
+
+	* loop.c (strength_reduce): Don't emit an insn after loop_end to
+	set the final value of a reversed biv.  There is already an insn
+	there setting the biv's proper final value.
+
+Sun Apr 14 18:32:05 1991  Michael Tiemann  (tiemann at cygnus.com)
+
+	* gnulib1.c (various functions): Added declaration of INTIFY to
+	every function which has a FLOAT_ARG_TYPE argument or return value.
+
+Sun Apr 14 18:31:59 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* c-decl.c (store_parm_decls): Traditional float parm becomes double.
+
+Sat Apr 13 17:35:07 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* m68k.md (storing 32-bit field with movl): Allow any immediate arg 3.
+
+	* expmed.c (store_bit_field): For fields bigger than a word:
+	Avoid special use of SImode, and don't crash if VALUE is CONST_INT.
+
+Fri Apr 12 02:04:46 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* reload.c (find_reloads): Like prev change here, for optional reloads.
+
+	* tm-sparc.h (FUNCTION_BLOCK_PROFILER): Must set %o0 to the address
+	LPBX0 by adding in the low part of the address before calling
+	___bb_init_func.
+
+	* tm-next.h (ASM_OUTPUT_CONSTRUCTOR, ASM_OUTPUT_DESTRUCTOR):
+	New macros.  Place reference to constructor or destructor into
+	constructor or destructor section.
+
+	* tm-next.h (EXTRA_SECTIONS, EXTRA_SECTION_FUNCTIONS):  Add
+	new constructor and destructor sections.
+
+	* jump.c (squeeze_block_notes,squeeze_notes): Chage the name of
+	squeeze_block_notes to squeeze_notes.  Also handle LOOP_BEG, LOOP_CONT
+	and LOOP_END notes, since these must remain in their original order.
+
+	* cccp.c (skip_to_end_of_comment): Handle warn_comment.
+
+	* m68k.md (dbra patterns): Use `=' in constraint of op 0.
+
+	* gcc.c (process_command): Handle -save-temps.
+	(do_spec_1): Handle %g like %b if -save-temps.
+	(verbose_flag): Renamed from `vflag'.

+
+Fri Apr 12 00:57:48 1991  Jim Wilson  (wilson at cygnus.com)
+
+	* sched.c: Update all comments to reflect source changes.
+	Make old_live_regs a static global, instead of local to schedule_block.
+	Schedule_block is now void, since its return value was always 1.
+	Rename last_function_call_not_const to last_pending_memory flush.
+	This can not be a CALL_INSN or a INSN that writes memory.
+	New variable pending_lists_length so that the lists can be flushed
+	when they get too long.
+	Use GET_RTX_CLASS instead of multiple GET_CODE calls whenever it
+	makes sense.
+	(read_dependence): New Function.  Returns one if two reads are
+	dependent.  This can happen if both are volatile reads.
+	(true_dependence, anti_dependence, output_dependence): Two volatile
+	memory access are always dependent.
+	(order_calls): Function deleted.  It was very short, it was only called
+	once, and it no longer did what its name implied.  Its one call was
+	replaced with the body of the function.
+	(sched_analyze_1): Correctly handle stripping of SUBREGs, etc from
+	the set dest.
+	If the pending lists are longer than 32 when processing a memory
+	write, then make this write depend on all previous and all future
+	memory accesses so we can flush the pending list.  This is necessary
+	because the algorithms used are O(N*N).
+	(sched_analyze_2): For memory reads, check whether it is read
+	dependent on any previous memory read (this can happen if both reads
+	are volatile).
+	(sched_analyze_insn): Replace call to order_calls with the body of
+	that function.
+	(sched_analyze): Don't clear last_memory_pending_flush for a non-const
+	call, since any future call must still depend on all previous memory
+	accesses.
+	(sched_note_set): Correct handling of SUBREGs, etc.  For partial sets
+	of a register, must treat this exactly the same way as flow.c, i.e.
+	a partial set of a register does not kill the register.  Delete
+	ifdefed out code which is obsolete.

+	emit a label after the last insn to be deleted, to ensure that no
+	delete_insn call will delete past that point.
+	(precondition_loop_p): Use global loop_* variables setup by
+	loop_iterations, instead of trying to calculate their values again.
+	(copy_loop_body): Don't emit copies of the start_label.
+	(approx_final_value): COMPARISON argument now passed as the pair
+	COMPARISON_CODE and COMPARISON_VALUE.
+	(find_splittable_regs): When completely unrolling a loop, and the

+	create a new register to hold its initial value for splitting.
+	(loop_iterations): Set the new global variables loop_*.
+	If the comparison value is an invariant register, then search the insns
+	before the loop to try to find a constant value for the register.

+
+	* combine.c (gen_lowpart_for_combine): Copy code for CONST_DOUBLE
+	from gen_lowpart instead of calling it; it will abort for certain
+	floating-point cases, while we will just surround the object with
+	a SUBREG.
+
+Thu Apr  4 22:31:36 1991  Jim Wilson  (wilson at cygnus.com)
+
+	* unroll.c (new file): Implements loop unrolling.  Completely
+	unrolls small constant bounded loops.  Unrolls other constant
+	bounded loops by an amount modulo the number of iterations so that
+	only one exit test is needed.  Preconditions loops whose iteration
+	count can be calculated at run time, so that only one exit test
+	is needed.  Can also unroll any other loop by having multiple
+	copies of the exit tests.  Tries to simplify addresses while
+	unrolling.
+
+	* tree.def: BLOCK trees have 4 fields, not 5.
+
+	* toplev.c: Add new flag -dt to dump RTL after the second cse pass.
+	Define two new flags, flag_unroll_loops and flag_unroll_all_loops,

+	after delayed branch reorganization.
+
+	* stmt.c (find_loop_tree_blocks): New function.  Creates a mapping

+	trees corresponding the loop indicated by LOOP_NUMBER, so that the
+	BLOCK notes inside the loop will still match the BLOCK trees for
+	the loop.
+
+	* rtl.h: Document the new named pattern
+	"decrement_and_branch_until_zero".  Add macros to access new
+	field of inline_header rtx, which holds a pointer to the function's

+
+	* rtl.def: New entry for inline_header to hold a pointer to the
+	function's original DECL_INITIAL tree.
+
+	* loop.h (new file): Move many declarations from loop.c to the new
+	file loop.h, and change some from static to extern, so that they
+	can be shared with unroll.c.  Also globalize names for variables
+	changed from static to extern.
+
+	* loop.c: Move many declarations from loop.c to the new	file loop.h,
+	and change some from static to extern, so that they can be shared
+	with unroll.c.  Add misc comments to better explain the code.
+	Change name of global arrays loop_start and loop_end to
+	loop_number_loop_starts and loop_number_loop_ends so that they won't
+	be confused with local loop_start and loop_end variables.
+	New variables loop_number_exit_labels, loop_number_first_block,
+	loop_number_last_block, loop_number_block_level, loop_n_iterations.
+	Old_max_reg renamed to max_reg_before_loop.  Max_uid renamed to

+	support.  Add call to find_loop_tree_blocks to create the BLOCK tree
+	to loop map needed when unrolling and outputting debugger info.
+	(scan_loop): Fix setting of maybe_never of label/jump.  The old code
+	always failed.
+	(prescan_loop): Delete obsolete code.
+	(find_and_verify_loops): Add code to initialize
+	loop_number_exit_labels.
+	(mark_loop_jump): Add code for keep chain of loop_number_exit_labels
+	for each loop.
+	(invariant_p): LABEL_REFs are not invariant when doing loop unrolling.
+	Remove static from definition, so that it can be called from unroll.c.
+	(strength_reduce): Change name of variable maybe_never to
+	not_every_iteration, to help emphasize that it is not the same
+	as the variable maybe_never in the code motion code.  Modify code
+	that computes its value so that it will be false more often, resulting
+	in better code.
+	(strength_reduce): Added code to call the new loop unrolling
+	functions, e.g. unroll_loop, loop_iterations, etc.
+	(strength_reduce): New code to handle biv's and giv's which must
+	be set to their final_value after the loop exits.
+	(strength_reduce): Reversed giv's and biv's must have their values
+	calculated differently.  Add new field reversed to struct induction,
+	and code to check and use its value.
+	(strength_reduce): Only check value of bl->nonneg for architectures
+	that have a decrement_and_branch_until_zero instruction.
+	(find_mem_givs): New argument loop_start.
+	(record_giv): New argument loop_start.
+	The always_computable field for DEST_ADDR givs is always set true.
+	New code to check for case of spaghetti code, in which case the

+	(check_final_value): New function. For givs which are not otherwise
+	replaceable, try to calculate their final value, and then try
+	to use this to make them replaceable.
+	(update_giv_derive): Skip inner loop if giv is known to be underivable
+	at the beginning.  Must set cant_derive if we pass an insn that
+	modifies the giv's biv, and we can't calculate an adjustment.
+	(emit_iv_add_mult): Remove static definition so that it is callable
+	from unroll.c.
+	(check_dbra_loop): Reversed biv's must be marked as such, so that
+	they can be treated specially in the rest of loop.c.
+	(final_biv_value): Moved to unroll.c, alongside the new function
+	final_giv_value.  Extensively rewritten to work for most common
+	cases.
+	(update_reg_last_use): Verify that insns have a valid luid before
+	trying to use it.  Don't perform any action if no value luid.
+	(get_condition): Correct initial comment.
+	(get_condition_for_loop): Remove static definition so it is callable
+	from unroll.c.
+
+	* integrate.h: Replace `tree' use in definition with

+	this file is included.	
+
+	* integrate.c (initialize_for_inline): Pass additional argument,
+	the DECL_INITIAL (fndecl) tree, to gen_inline_header_rtx.  Update
+	and correct comment.
+	(save_for_inline_copying): Copy the decl tree, so that virtual reg
+	instantiation, and loop unrolling, won't affect the saved tree.
+	(copy_decl_tree): New argument, functionbody, which distinguished
+	between calls from save_for_inline_copying and calls from
+	expand_inline_function.
+	(copy_rtx_and_substitute): Return orig instead of aborting when
+	inline_target is zero so that loop unrolling can use this code.
+
+	* gcc.texinfo: Document the new optimization flags -funroll-loops
+	and -funroll-all-loops, the new dump option -dt, and the new named
+	pattern	"decrement_and_branch_until_zero".
+
+	* flags.h: Define two new flags, flag_unroll_loops and
+	flag_unroll_all_loops.
+
+	* emit-rtl.c (gen_inline_header_rtx): New argument
+	original_decl_initial.  Pass to gen_rtx call.
+
+	* alliant.md, m68k.md: Name the pattern that uses the REG_NONNEG
+	note to "decrement_and_branch_until_zero".
+
+	* Makefile.in: Add source file unroll.c and header file loop.h to
+	the cc1 dependencies.  Add *.cse2 to the list of files deleted by
+	`make clean'.

+	be done	for an explicit call to objc_msgSend (this should never
+	happen, but just in case).
+
+	* emit-rtl.c (gen_lowpart): Reverse #if for CONST_DOUBLE case.
+
+Thu Apr  4 13:27:02 1991  Michael Meissner  (meissner at osf.org)

+	changing mode of a MEM.
+	(gen_lowpart_for_combine): Likewise.

+	operands properly.
+
+	* expr.c (expand_expr, case NOP_EXPR): If no target was specified,
+	use convert_to_mode instead of convert_move; this may return a SUBREG.
+

+	If testing A & CONST and the result fits in a smaller mode, try
+	the compare there.
+
+	* cse.c (simplify_binary_operation): If eliminating reference to
+	operand, verify	that it has no side effects.

+
+	* cplus-type2.c (digest_init): Strip NON_LVALUE_EXPRs.
+
+	* cplus-tree.c (__eprintf): Added this function from gnulib2 until
+	gnulib configuration is worked out.
+
+	* cplus-parse.y (member_init): Call do_member_init.  Previous code
+	was wrong (using a goto to factor common code) because the parse

+	(move_movables, strength_reduce): Pass new parameter to replace_regs.
+	* jump.c (duplicate_loop_exit_test): Make new pseudos for pseudos
+	used only in loop exit test; this prevents unnecessay sharing
+	between code inside and outside of loop.
+	* toplev.c (rest_of_compilation): Call reg_scan before jump.
+
+	* combine.c (distribute_notes): If we are searching back for the last
+	use of a register I3 and I2 no longer use and the last use is a SET
+	of that register, place a REG_UNUSED note instead of a REG_DEAD note.
+	No longer need handle REG_DEAD note for output of I3; it will now be
+	a REG_UNUSED note.
+
+	* combine.c (try_combine): If I3SRC is a register and I2 is a
+	multi-output insn, see if we can replace one of the outputs with
+	I3DEST.  If so, move LOG_LINKS pointing at the other outputs to
+	now point to I3 instead of I2.

+	(significant_bits): Return mode mask if mode wider than host int.
+	Don't get confused by (zero_extend (const_int ..)) and similar where

+	Arithmetic operations now always have same modes on operands as
+	on the result.
+
+	* jump.c (jump_optimize): Set this_is_{simple,cond}jump at the start
+	of loop, not in middle, and use consistently.
+	Use can_reverse_comparison_p in case where we make scc insn.
+	Don't use can_reverse_comparison_p when we call invert_jump.
+	Use indirect_jump instead of indirect_exp.
+	Check invert_jump's result before making any other changes; handle
+	failure.
+	Simplify code that looks for and deletes USE insns.
+	(jump_back_p): Call can_reverse_comparison_p only if we have to
+	reverse the comparison.
+	(can_reverse_comparison_p): Accept comparison expression and insn
+	it comes from.
+	Rework to be more general now that we have MODE_CC and tighten
+	up a bit.
+	(invert_jump): Allow invert_exp and redirect_jump to fail.
+	(invert_exp): Only invert jump, don't change target.
+	If can reverse comparison code, try it using validate_change.
+	If that doesn't work, swap the arms of the IF_THEN_ELSE.  If that
+	doesn't work, return 0.
+	(redirect_exp): Now static.
+	* expr.c (do_jump_for_compare): Call invert_jump to invert jump
+	to false label after emitting jump; if this fails, convert to
+	jump around unconditional jump to false label.

+	avoids inverting branches.
+	* reorg.c (optimize_skip, relax_delay_slots): Always allow invert_jump
+	to fail.
+	* rtlanal.c (single_set): Return 0 if not INSN, CALL_INSN,
+	or JUMP_INSN.
+
+	* reload1.c (eliminate_regs): If any eliminable regs occur in a USE,
+	eliminate them.
+
+Tue Mar 26 00:09:18 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

+	genoutput and output the INSN_UID as well.
+	* rtl.c (insn_name_ptr): Provide an alternate definition to avoid
+	link errors when rtl.o is not linked with insn-output.o.
+	(print_rtx): When printing the INSN_CODE field of an insn, print

+	* flow.c (reg_first_use): Deleted.

+	as globals.  These are registers that were never set.
+	(allocate_for_life_analysis): Don't allocate reg_first_use.
+	(propagate_block): Search for cc0-setting insn with prev_nonnote_insn.
+	(mark_set_1): Don't set reg_first_use.

+	* global-alloc.c (global-conflicts): Dead outputs are now denoted by
+	REG_UNUSED notes, not REG_DEAD.
+	* reload.c (find_dummy_reload): Delete test of REG_UNSET; add test
+	of REG_UNUSED.
+	(find_equiv_reg): Don't re-use an output marked as REG_UNUSED;
+	we want these notes to be accurate; this would rarely win anyway.
+	* reload1.c (emit_reload_insns): Test REG_UNUSED to see if an
+	output won't be used any more.
+	* reorg.c (mark_target_live_regs): Use REG_UNUSED notes to kill	
+	registers dead after an insn.
+	* rtl.c (reg_note_name): Delete REG_UNSET, add REG_UNUSED.
+	* rtlanal.c (single_set): Ignore a SET whose output has a REG_UNUSED
+	note.
+	* sched.c (update_first_use): Deleted.
+	(update_links): No need to call update_first_use.
+
+	* local-alloc.c: Major changes to use REG_UNUSED notes, make
+	handling of only-set registers more consistent, and allow
+	two consecutive CLOBBERs to share a register.  Also, avoid loops
+	over all register each basic block; eliminating these make local-alloc
+	three times faster!
+	Quantity numbers now start at zero.
+	(qty_first_reg, reg_next_in_qty): New variables.
+	(qty_clobber): No longer needed.
+	(reg_qty): -1 if register cannot be allocated by local-alloc.
+	Now undefined for hard registers.

+	Initialize reg_qty once per function.
+	Don't initialize qty_... vars that are always set before use.
+	(block_alloc): Delete insn_map, max_uid, and call_used.
+	Insn numbers start at 1 and we have two entries in regs_live_at
+	for each insn.
+	Search for REG_NO_CONFLICT block when we see a CLOBBER insn; this
+	avoids having already seen sets to the output register.
+	Call wipe_dead_reg for anything in a REG_UNUSED note.
+	Delete references to reg_first_use.
+	Don't check for invalid birth and death here.
+	Don't call qsort if we have 0 or 1 quantities.
+	Find all registers for a quantity using reg_next_in_qty chain instead
+	of looping over all pseudos.
+	(combine_regs): Refine tests to agree with new conventions.  
+	Never tie pseudos if SREG already has a quantity assigned.
+	When updating size, use reg_next_in_qty instead of looping over
+	all registers.
+	(reg_is_set): Just call reg_is_born.  Where it is born depends on
+	whether we have a CLOBBER or not.  Birth location is now twice
+	the insn number.
+	(reg_is_born): Handle case when a hard reg is born before the
+	current insn.
+	Show we don't know the death location.
+	(wipe_dead_reg): Parameters are now just register and an in/out flag.
+	Death locations are now twice the insn number.
+	Support hard regs that die immediately after current insn.
+	Don't make REG_UNSET notes.
+	(find_free_reg): Validate BIRTH and DEATH here.
+	We no longer have qty_clobber.
+	(post_mark_life): Eliminate CLOBBER parameter.
+	(no_conflict_p): Now passed CLOBBER at start of block.  Return 0 if
+	can't find death note or if R1 is a hard register.
+
+	* m68k.md (divsi3, udivsi3): Remove patterns.  Using divmodsi4 and
+	udivmodsi4 produces better code.
+	(divmodsi4, udivmodsi4): If remainder isn't needed, use divsl/divul
+	instead of divsll/divull.
+
+	* integrate.c (expand_inline_function): Remove change of March 20th.
+	Instead, expand args in two passes.  First, expand all that go
+	into registers.  Then do those in memory with store_expr.
+
+	* integrate.c (initialize_for_inline): Put the original copy of the
+	address into ARG_VECTOR; the new one will be modified.
+
+	* reload.c (push_reload): Handle paradoxical SUBREGs on an output
+	as well as an input.
+
+	* flow.c (mark_label_ref): Don't blow up when X is 0.
+
+	* combine.c (make_compound_operation): Fix typos; result of 
+	exact_log2 is interesting if >=0.
+
+	* a29k.md (store_multiple): Allow gen_store_multiple{_no,}_bug to fail;
+	we fail if they do.
+
+	* reorg.c (emit_delay_sequence): Record that we deleted a BARRIER
+	and restore it precisely on those occaisions.
+

+
+Sat Mar 23 18:04:23 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* cse.c (simplify_unary_operation): Add missing cases for ABS and FFS.
+
+	* alliant.md: Eliminate unneeded patterns: HImode zero_extract, 
+	(set (cc0 (subreg ...))), (set (cc0) (and ...)),
+	(and (zero_extend ...) ...), shift right of 24 and 16.
+	Use alternatives to select assembler template when possible.
+	Use const_int_operand instead of immediate_operand when
+	possible to avoid explicit test for CONST_INT.
+	Write add-and-branch patterns with PLUS removed, the way combine
+	produces them.
+
+	* rtlanal.c (refers_to_regno_p): If X is a SUBREG of a hard
+	register, treat it as if it were the appropriate register.
+	CLOBBER doesn't refer to anything.
+	
+	* final.c (final_scan_insn): Use prev_nonnote_insn, not PREV_INSN,
+	to find cc0-setting insn from cc0-using insn.
+
+	* global-alloc.c (find_reg): Don't look for other registers to
+	renumber unless we know that we are sharing registers.
+
+	* emit-rtl.c (end_sequence): Fix typo that prevented speedup of
+	Dec 26th from doing anything.
+
+	* toplev.c (do_abort): New function, just calls abort.
+	(main): Set lang_expand_expr to address of do_abort; abort might be
+	a macro that is more than just a function name.
+
+	* cse.c: (qty_... variables): Refined to be undefined for indices
+	less than MAX_REG.  Thus, we need not intialize them at the start
+	of a basic block and can instead inialize a quantity as we create it.
+	(reg_{next,prev}_eqv): These variables will now be defined only when
+	reg_qty[N] != N and hence need not be initialized every block either.
+	(new_basic_block): Need not initialize reg_rtx for new block; the
+	only time we can inherit values from previous blocks is for hard
+	regs and it doesn't matter in that case.
+
+	* c-parse.y (yylex): Avoid use of size_t; it may not be defined.
+	Cast alloca to (char *).
+
+	* out-romp.c (update_cc): cc_status.value[12] can also be a COMPARE,
+	so use reg_overlap_mentioned_p to see if an insn that modifies a
+	register invalidates cc0.
+
+	* reorg.c (link_cc0_insns): If next insn is a SEQUENCE, the insn
+	using cc0 is the first insn in the sequence.
+	(mark_target_live_regs): Don't assume that a REG_DEAD note always
+	refers to a register.
+
+Sat Mar 23 15:35:59 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* reload1.c (reload_reg_free_before_p):
+	An input reload is use before an output or output address reload.
+
+	* genoutput.c (validate_insn_alternatives): New function.
+	Loop over insn's alternatives to find out how many
+	alternatives the insn pattern is to support.  Verify that if
+	any alternatives are specified for a given operand that the
+	number of alternatives match the numer of alternatives for
+	this insn.
+	(gen_{insn,peephole,expand,split}): Call
+	`validate_insn_alternatives' after scanning the insn.  This
+	sets up the value N_ALTERNATIVES for the insn so that
+	`process_template' can check that the number of alternitves
+	given matches the number of asm choices for `@' constructs.
+
+Sat Mar 23 08:09:57 1991  Michael Meissner  (meissner at osf.org)
+
+	* dbxout.c (toplevel, dbxout_init): Instead of always using `Ltext'
+	as the label at the beginning of the text region, properly localize
+	it, so that machines which do not put leading underscores in front
+	of external names do not have a problem if the user uses `Ltext'.
+	(dbxout_init): Call text_section before putting out localized
+	`Ltext', in case ASM_FILE_START put us into a different section.
+
+Fri Mar 22 19:26:23 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* a29k.md (jumpfdec): Simplify pattern to match what combine will
+	produce; remove reversed pattern.
+	* out-a29k.c (gen_reg_operand): Speed up by not calling
+	register_operand; check register number ourself.
+

+	output reload, which will cause problems.
+
+	* varasm.c (assemble_variable): Ensure DECL_INITIAL is non-zero
+	before we reference it; it might be zero if -fno-common.
+

+	Use const_int_operand as predicate instead of checking for CONST_INT.

+
+	* jump.c (duplicate_loop_exit_test): Make copy of contents of

+
+	* recog.c: Include insn-attr.h.
+	(general_operand): If we have insn scheduling, don't allow paradoxical

+	(unlink_notes): Work from back-to-front instead of front-to-back.
+	(new_sometimes_live): Fix code that looks for an element already in
+	the table.
+	(schedule_block): New variable TAIL_PRIORITY  used to help determine
+	max IPC of scheduled code.  Also, for now we analyze (schedule) all
+	blocks, even ones which won't benfit from scheduling.  This is
+	necessary to keep register live info correct, but has the
+	disadvantage of screwing *all* debug info, not just for the blocks
+	that were scheduled.
+	(update_links): Fix complicated code that was to be a simple
+	head-cons to be a simple head-cons.
+	(schedule_insns): Update REG_LIVE_LENGTH and REG_N_CALLS_CROSSED

+
+	* out-sparc.c (output_block_move): Use `rtx_alloc' instead of
+	`gen_rtx' to cons a CONST_INT whose INTVAL we can change.
+

+	If we are on a machine (like a Vax) that has only arithmetic shifts,
+	convert logical to arithmetic shifts when it doesn't matter 
+	which shift is used (simplify_shift_const canonicalizes to
+	logical shifts).

+	pattern can be split into two insns.
+	(try_combine): If we are combining three insns and can't recognize the
+	new pattern, try to split it.
+	Call new functions below to update insn status.
+	Return insn at which to continue scan.
+	(adjacent_insns_p, add_links, remove_links): Deleted.

+	Be more precise about when we can combine insns involving cc0.

+	If -fexpensive-optimizations, try to simplify I1 or I2.
+	Handle (set (foo) (const_int 0)) followed by a STRICT_LOW_PART
+	assignment to FOO as a ZERO_EXTEND.
+	(subst): Quit very early if X is a root node (like PC0).
+	Remove most canonicalizations done in first switch statement; now
+	done elsewhere.
+	Call simplify_{unary,binary,ternary}_operation.
+	Add cases involving logical and arithmetic operations applied
+	to comparison operators or values with only one significant bit.
+	Add more cases involving ABS since comparisons returning values
+	can be done with ABS.
+	Avoid generating (const (const ...) ...).
+	Convert (xmult (x_extend ...) ...) to a widening multiply.
+
+	(gen_rtx_combine): New function to search for an operation in

+
+	*out-m68k.c (output_function_epilogue):	 Don't output
+	anything if the epilogue was output as RTL.  We detect this
+	by the barrier insn which is always placed after a return
+	insn.  This machine-independent test should probably be moved
+	back into final.c and removed from out-sparc.c and out-m88k.c.
+
+	* out-next.c:  Don't #include "flags.h".

+
+	* Makefile.in (dwarfout.o): Added this rule.
+
+	* dwarfout.c (FT_*_long_long): Added default definitions for all of
+	these extended fundamental type codes to cater to plain vanilla
+	<dwarf.h> file which do not define codes for these fundamental types.
+
+	* dwarfout.c (TREE_UID): Added a local definition of this macro
+	because gcc v2 no longer provides a definition for it and because
+	dwarfout.c needs some way of getting a unique numeric code for each
+	type.
+
+	* dwarfout.c (CLASSTYPE_*): Added some local default definitions
+	for these macros in order to get around the fact that they are
+	currently defined only in cplus-tree.h (and rms wants dwarfout.c
+	to be language independent).
+
+	* dwarfout.c (BITFIELD_OFFSET_*): Added some local macros to help
+	compute various quantities relating to bitfield offsets.
+
+	* dwarfout.c (location_attribute): Changed code which outputs location
+	attributes for bitfield so that it uses gcc2 macros.
+
+	* dwarfout.c (byte_size_attribute): Changed code which outputs the
+	byte_size attribute so that it no longer uses the obsolete
+	DECL_SIZE_UNIT macro (from gcc1).
+
+	* dwarfout.c:  Replaced all uses of the obsolete macro TREE_PACKED
+	to uses of the new gcc2 macro DECL_BIT_FIELD.
+
+	* dwarfout.c (deriv_list_attribute): Fixed typo "decl" => "type".
+
+	* dwarfout.c (output_dies_for_type): Replaced bogus reference to the
+	non-existant routine "output_member_function_type_die" with a proper
+	reference to the routine "output_subroutine_type_die".
+
+	* dwarfout.c (output_symbols_for_block): Fixed calling error which
+	was introduced by rms.
+
+	* dwarfout.c: Replaced all uses of the obsolete macro STMT_SUBBLOCKS
+	with uses of the new gcc2 macro BLOCK_SUBBLOCKS.
+
+	* dwarfout.c (output_symbol): Removed reference to TAG_DECL.  The
+	use of TAG_DECLs was an early idea which didn't work out.
+
+	* dwarfout.c: (dwarfout_init): Changed name from dwarfout_initialize
+	because rms failed to do so when he changed the name in the call.

+	(CONSTANT_ALIGNMENT): Align constructors on word boundaries.

+	define_expand that converts the expansion into the appropriate
+	shifts.  Add insns that do sign extension from memory, which the
+	optimizer will utilitize if the thing being sign extended really
+	comes from memory.  This allows the shifts to compete for CSE, at a
+	potential cost of generating worse code if reload spills a HI or QI
+	register to the stack.

+	argument to the slti instruction, use a hard coded regisiter 0.

+
+	* t-decrose, t-decstatn, t-encrose, t-i386rose, t-mips: Remove
+	collect2 from EXTRA_PASSES, as collect2 does not need installing as
+	collect2.  Also, change the symlink back to a hard link.
+
+	* Makefile.in: Add collect2 to STAGESTUFF as it is something that
+	needs removing or moving to stagen, but it should not be installed.

+
+	* combine.c (simplify_comparison): Swap evaluation of OP0 and OP1 so

+
+	* i386.md (mulhi3,mulsi3): If a multiply by constant 128, use the
+	two operand multiply instead of three operand form: the AT&T
+	assemblers generate incorrect object code for the latter.
+
+Mon Dec 30 17:39:36 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* jump.c (jump_optimize): Complete last change: use expand_and result.
+
+	* reload1.c (emit_reload_insns): Check if reload_in needs a secondary

+
+	* dbxout.c (dbxout_type): Tiemann's DECL_IGNORED_P optimization (Nov
+	20) was a little too drastic: If it succeded, no type info was
+	emitted at all, which made for syntactically invalid stabs.
+	Instead, just set 'full=0',
+	* dbxout.c (dbxout_symbol): Re-write code for TYPE_DECL to be a
+	little cleaner.  It *seems* to work ...

+	put a TImode value in r11 as often.

+	* reload1.c (reload): Pass pointer to something_changed to

+
+	* cp-spew.c (do_aggr): New function. Looks ahead from AGGR to see if

+
+	* m68k.c (output_function_prologue, output_function_epilogue):
+	When saving/restoring only 2 registers, do so with two "movel"

+
+Wed Dec 11 06:45:08 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)

+
+Tue Dec 10 15:41:03 1991  Michael Meissner  (meissner at osf.org)

+	moved to gnulib2.c.
+
+	* Makefile.in (collect2, collect2.o): Change to use the default

+	otherwise, collect2 will create a circular dependency.  Also, pass
+	LDFLAGS when linking.
+
+	* collect-osf.c (write_s_file): Change to the new way of doing
+	constructors and destructors of having an end marker instead of a
+	count.

+	destructors of having an end marker instead of a count.  Cast all
+	alloca calls to be the appropriate pointer type.  Put both
+	constructors and destructors into the data section, because the MIPS
+	tools do not like non-instructions in the .text section.
+
+	* decrose.h (HAVE_ATEXIT): Define, OSF/1 has atexit.

+	needed, since constructor/destructor support moved into gnulib2.c.
+

+
+	* t-decstatn (CCLIBFLAGS, GNULIB2_CFLAGS): Define so that gnulib1
+	and gnulib2 are both compiled with -G 0, in case the users compiles
+	and links this way.  It also fixes a bug where the constructors and
+	destructors that collect2 produces are in the big data section, but
+	gnulib2 thinks they are in the small data section, because it only
+	sees a pointer.
+	(ld): Add -f to remove old ld link to collect2, if it exists.
+
+	* t-mips (CCLIBFLAGS, GNULIB2_CFLAGS): Define so that gnulib1
+	and gnulib2 are both compiled with -G 0, in case the users compiles
+	and links this way.  It also fixes a bug where the constructors and
+	destructors that collect2 produces are in the big data section, but
+	gnulib2 thinks they are in the small data section, because it only
+	sees a pointer.
+	(ld): Add rule to link collect2 to ld.
+	(EXTRA_PASSES): Build collect2 (aka ld).
+
+	* xm-mips.h (alloca): If not GNU C, declare alloca to be char *.
+
+	* mips-tfile.c (add_aux_sym_tir): Move code to record bitfield size,
+	so that it agrees with MIPS ECOFF practice, rather than the
+	documentation, which affects enum bitfields.  Changes from Per
+	Bothner.

+	instruction would modify the hi/lo registers.

+	(mips_move_2words): Move DImode to/from hi and lo registers is now

+	(override_options): Initialize mips_hard_regno_mode_ok.  Restrict

+	a double int for the HI:LO combination.
+	(compute_frame_size): Don't set the initialized member until reload
+	has completed, since otherwise the information may change.
+
+	* mips.md (various): Add 64 bit integer operations for addition,
+	subtraction, negation, and, inclusive or, exclusive or, one's

+	multiply, which the compiler then uses to construct 64 bit
+	multiplies.
+	(mulsi3): Break mul into it's two instructions, and schedule the
+	two nops needed for the mflo instruction.  Don't allow an integer

+	(movdf define_split): Add a define_split to separate the two parts
+	of DFmode register pairs when using GP registers.
+	(mov??_internal): Change condition to call memory_operand, instead
+	of just checking for MEM, which disallows (subreg (MEM)) during

+	(negsi2): Turn back into a real insn instead of just a
+	define_expand for subsi3.

+	define_expand for norsi3.
+	(andsi3, iorsi3, xorsi3): Be more liberal than the real machine, and
+	allow 32 bit constants to improve the code generated for bitfields,
+	at the expense of potentially not moving the constant out of loops.
+	(various): Add = constraint to all clobbers.
+	(fix_trunc*): Go back to old method of using two clobbers, since
+	unoptimized compiles call abort otherwise, when returning the result
+	of truncating a float as a function result.
+
+	* tm-mips.h (delay_type): New enum to express different types of
+	delay slots.
+	(mips_load_reg3, mips_load_reg4): Declarations for more registers
+	to check for needing nops.  Used by multiply/divide to schedule
+	the two nops needed after mfhi/mflo if the next instruction would
+	clobber the register.
+	(CONDITIONAL_REGISTER_USAGE): If -msoft-float, disable all FP
+	registers.
+	(MASK_DEBUG_G): Add comment saying -mdebugg turns of new DImode
+	patterns, in case the code is wrong.
+	(HARD_REGNO_NREGS): All FP registers use register pairs, so that
+	SF in a GP register takes only one register, and SI in a FP
+	register takes 2.
+	(HARD_REGNO_MODE_OK): Change macro to reference the array
+	mips_hard_regno_mode_ok, which is now built in override_options.
+	(CONST_OK_FOR_LETTER_P): 'N' is now for negative numbers, 'O' is
+	an exact power of 2, and 'P' is now for positive numbers.
+	(PREFERRED_RELOAD_CLASS): If -msoft-float, never prefer a FP
+	register.
+	(PREFERRED_RELOAD_CLASS_FM): Delete, since nobody uses it.
+	(FINAL_PRESCAN_INSN): Check for mips_load_reg3 and mips_load_reg4
+	being mentioned.  Also add a missing tab when more than one delay
+	slot.
+	(CONST_COSTS): Make all constant ints cost 0 to lower register
+	pressure according to Richard Kenner.
+	(RTX_COSTS): Adjust costs for DI, SF, and DF modes, and add ABS/FFS
+	costs as well.
+	(REGISTER_MOVE_COSTS): Bump costs for moving between register
+	classes, so that reload doesn't try to store int type values in the
+	floating point registers.

+	* dbxout.c (dbxout_type): Tiemann's DECL_IGNORED_P optimization (Nov

+
+	* cp-parse.y (yyprint): Handle PRE_PARSED_CLASS_DECL.

+
+	* cp-pt.c (overload_template_name): If not class-level, push

+
+	* collect-ld: Always run collect if collect is installed.

+
+	* gnulib2.c (__eprintf): Undef NULL.
+
+	* c-typeck.c (build_array_ref): Ref is volatile if array is volatile.
+
+Fri Nov 15 19:53:41 1991  Jim Wilson  (wilson at wookumz.gnu.ai.mit.edu)
+
+	* c-typeck.c (build_binary_op_nodefault): Delete ERROR_CODE
+	argument because it is always the same as CODE.  Add new argument
+	CONVERT_P, and call default_conversion on the operand trees if
+	true.  Rename to build_binary_op.
+	(old build_binary_op): Deleted because it is now unnecessary.
+	* c-common.c, c-convert.c, c-decl.c, c-tree.h, c-typeck.c: All
+	callers and other references to build_binary_op* fixed.
+	* c-typeck.c (new build_binary_op): Add warning message for
+	comparisons of signed and unsigned variables that won't give the
+	expected result due to unexpected sign extension.
+
+	* expr.c (convert_move): Add TFmode support and clean up code.

+
+	From Per Bothner:
+	* collect2.c: Define vfork as fork for USG.  Rewrite to not use
+	prototypes, so it doesn't need gcc for compilation.
+	(main): No longer uses static sized array for ld arguments, so
+	that long command lines will work.  Vfork ld instead of running
+	via popen with nm.
+	(write_hooks): Use type names not variable names in sizeof calls.
+
+Fri Nov 15 15:01:41 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)

+
+Fri Nov 15 22:22:32 PDT 1991  Mike Stump (mrs at csun.edu)
+
+	* configure: Recognize only canonical names.  Added missing entries
+	for some configurations that obviously have not been tested in a
+	while.
+
+	* config.subr: Massive overhaul.  It claimed to canonicalize
+	the machine specification, but it never really did.  Now it
+	does.  In general, it is not necessary to specify the os for
+	popular machines that have a popular os, or given the os, it
+	can sometimes figure out the vendor.  Added in all the old
+	ways of specifying machines from configure.  Also added
+	support for all (before it was missing a few) of the tm-*.h
+	files.  It now supports the concept of guessing the vendor for
+	a given CPU type.  It now supports the concept of guessing the
+	os version given the vendor and/or the CPU type.  Changed the
+	default os for vax to ultrix, changed the default os for i386
+	to sco.
+
+	* collect-ld:  New file.  It is useful when compiling C++ programs
+	on machines that use collect.  This includes the decstation.

+	(init_reload): Initialize reload_{in,out}_optab.
+	(emit_reload_insns): Handle cases where a secondary reload

+	one from the absolute value of something to PLUS, since we
+	subtract one using a PLUS operation.

+	emit_store_flag.
+	(simplify_comparison, cae IOR): Similarly, for IOR.
+
+	* tm-rs6000.h (BRANCH_COST): Define as 2.

+Thu Nov 14 16:42:19 1991  Michael Meissner  (meissner at osf.org)
+
+	* mips-tfile.c (all): Change small allocation requests to use
+	separate allocation and free functions, instead of using the word8
+	union to hold each request.  In order to support this easily, a free
+	field was added to each small structure that is released.
+	(main): If debugging, print a summary of the number of small
+	allocations, frees, and the number of pages used.
+	(add_procedure, copy_objects): Stuff the pointer to the end symbol
+	into the shash chain, and use it's value to generate the new value

+	we use.

+	also accepts any address.
+
+	* unroll.c (final_biv_value): Make sure the initial value of the biv
+	is invariant if it is used after the loop.
+
+Tue Nov 12 23:16:51 1991  Michael Meissner  (meissner at osf.org)
+
+	* tm-mips.h (ASM_OUTPUT_REG_PUSH, ASM_OUTPUT_REG_POP): Correct so
+	ASM_OUTPUT_REG_PUSH actually does a push instead of pop, and vica
+	versa.  Also make ASM_OUTPUT_REG_POP turn on .set noreorder, and
+	increment the appropriate -mstats load delay counters.
+

+	(block_move_sequence): Call block_move_load_store.  For straight
+	line moves, have two outstanding loads before a store, for newer
+	machines that want two delay slots.
+	(block_move_loop): Call block_move_load_store.  Move 4 words per

+
+	First cut at ANSI-style exception handling (using
+	syntax and semantics of Stroustrup 2nd ed).
+	THIS IS WORK IN PROGRESS!
+	* cp-tree.h:  Declare flag_ansi_exceptions.
+	* gplus.gperf:  Add 'throw' (for ANSI exception handling),
+	and update private/protected/public from (old) cp-lex.c.
+	* cp-hash.h:  New file, generated from gplus.gperf.
+	* cp-lex.c: #include cp-hash.h, instead of requiring
+	manual cut-and-paste when keywords are changed.
+	* cp-lex.c:  Commented out some extern declarations that
+	were conflicting with inlines in cp-input.c.
+	Hooks for ANSI-style exception handling.
+	* cp-parse.y:  Parse ANSI-style exception stuff.
+	* cp-decl2.c:  Define new flag flag_ansi_exceptions.
+	* cp-decl2.c (finish_table):  Off-by-one error in
+	calculating index type.
+	* clus-decl2.c (finish_vtable_vardecl):  Add missing
+	TREE_OPERAND to get dossier decl.
+	* cp-except (cplus_expand_start_except):  Allow NULL name,
+	since there is no distinguished name for ANSI exceptions.
+	* cp-except (cplus_expand_raise):  Too few
+	parameters to expand_expr; add them.
+	* cp-except.c:  New functions for ANSI exceptions:
+	cplus_exception_name, ansi_exception_object_lookup,
+	cplus_expand_throw, ansi_expand_start_catch.
+	These are heavily hacked from similar old functions.
+
+	Try to make -fdossier work better (but more work is needed).
+	(Especially, generate fewer unneeded descriptors.)
+	* cp-class.c (add_virtual_function, finish_struct):  Do not
+	create a vtable just because of -fdossier.
+	* cp-gc.c:  Each type points to an array of fields,
+	instead of an array of pointers to fields.  Ditto for methods.
+	This saves one pointer per field or method by removing
+	unneded extra indirection.  Also other tweaks to save space.
+	* cp-decl.c (init_decl_processing):  Add length of
+	field and method arrays to descriptors, instead of
+	relying on NULL-termination (since we no longer have
+	the extra pointer array).
+	Make the parameter count and required count of
+	method descriptors be shorts.
+	* cp-method.c:  Remove no-longer-needed functions
+	build_i_desc_overload and build_m_desc_overload.
+
+	Other C++ fixes:
+	* cp-dbxout.c (dbxout_symbol):  Class types were
+	emitting only a "t" spec which made gdb unhappy.
+	Kludged it so that it once more emits "Tt".
+	* cp-tree.c (lang_output_debug_info):  Do emit debugging
+	info if this implementation file corresponds the the
+	type's interface, even if nothing is written.
+

+	(PCC_BITFIELD_TYPE_MATTERS): Define this to be 1.
+
+	* out-mips.c (block_move_loop): New function to generate a loop to

+	arguments, rather than a pointer to an array of operands.
+	(expand_block_move): Change block_move_call calling sequence.
+	(expand_block_move): If moving big aligned items, generate a loop to
+	do it, rather than calling memcpy/bcopy.
+	(override_options): If -msoft-float, 'f' constraint picks GP
+	registers.
+
+	* t-decrose (collect): Use ALL_CFLAGS instead of CFLAGS, since this
+	gets the shared library flags in x-decrose.
+

+
+	* tm-m88k.h (MEMORY_MOVE_COST): Define.

+
+	* jump.c (jump_optimize): When looking for a conditional jump
+	skipping an unconditional jump, be sure the conditional jump is
+	not an unconditional jump.
+
+	* combine.c (try_combine): If we make an unconditional jump,
+	be sure it is followed by a BARRIER.

+	of $(CCLIBFLAGS).
+	(gnulib1): Don't copy gnulib1.c into a temporary .c file before

+	Don't call mark_used_regs on dead insns.
+	(insn_dead_p): Use cc0_live to see if a set of CC0 is dead.
+	Correctly test if set of multi-word value is needed; set if dead only
+	if none of the words are needed.
+	(libcall_dead_p): Allow CALL to be in any part of PARALLEL.
+	Use insn_dead_p to see if SET of return register is dead; old code

+	needed.
+	(mark_used_regs): Likewise for REG_DEAD notes.

+
+	* cccp.c (timebuf): Declaration moved out of `special_symbol' and

+	(debug_output): New variable.
+	(main): Accept -g3 option and set debug_output when seen.
+	(main): Moved initializations of `outbuf' and `fp' to before call

+	Pass fp and &output to initialize_builtins so that it can write out
+	artificial #define lines for builtin symbols.
+	Call `output_line_directive' before doing each make_define or
+	make_undef so that when `debug_output' is in effect, we'll
+	get #line 0 directives before each artificial #define or #undef.

+	(make_undef): Added output buffer param so that make_undef could let
+	do_undef do output to stdout.
+	Call do_undef with a real output buffer.

+	like correctly formed #define directives.

+	* c-decl.c (store_parm_decls): Remove non-params from the list before
+	checking to see if the type of any element of the list is complete.
+	(pushlevel):  Fixed bug which caused scope of tagged types to be
+	incorrectly assigned to the outermost {} block of functions rather
+	than to the outermost binding contours of functions.
+	(pushtag):  Revised to clarify code used to find applicable
+	binding level for a tagname.
+	Set TYPE_CONTEXT of new tagged type so that dwarfout.c can tell
+	file-scope tagged types from non-file-scope tagged types.
+	Create a NULL-named TYPE_DECL node for each new tagged type
+	(even incomplete ones).
+	(finish_struct, finish_enum): Don't create NULL-named
+	TYPE_DECL nodes for complete tagged types.  (This is now done in
+	`pushtag' for *all* new tagged type declarations and definitions.)
+
+	* toplev.c (compile_file):  Adjust conditions under which
+	`dwarfout_file_scope_decl' is called during final traversal of
+	the chain of file-scope decls so that it is called also for
+	file-scope TYPE_DECLs.
+	(rest_of_decl_compilation):  Deleted call to `dwarfout_file_scope_decl'
+	for file-scope TYPE_DECLs; call `dwarfout_file_scope_decl' instead of

+	DINFO_LEVEL_* to prevent possible confusion about meaning.
+
+	* flags.h, toplev.c: (enum debug_info_type):  Renamed type from
+	`debugger' and cleaned up definition of type (including deletion
+	of useless EXTENDED_DBX_DEBUG code).
+	(use_gdb_dbx_extensions): Make declarations conditional on
+	DBX_DEBUGGING_INFO being defined.
+
+	* out-i860.c (output_fp_move_double, find_addr_reg):  Add return stmts
+	to avoid warnings when compiling with -Wreturn-type.
+	(output_delayed_branch):  Fix test for CONST_INT values which must be
+	loaded in two instructions (as two halves).
+	(function_epilogue):  Remove ASM_OUTPUT_EPILOGUE_SUFFIX.  (Superceeded
+	by ASM_DECLARE_FUNCTION_SIZE in varasm.c.)
+
+	* xm-i386.h (i386): Define in case the native host compiler doesn't.
+
+	* tm-svr4.h (SVR4): Define this rather than SVR4_target.

+	(tsubst): Check for several common values that won't be modified by

+	(tsubst, case FUNCTION_DECL): Don't return type passed if it has a

+	* jump.c (unsigned_condition, signed_condition): New functions.
+
+	* configure (vax): Set tm_file to tm-vax.h so "configure vax-dec-bsd"
+	works.
+
+	* combine.c (subst, case PLUS, MINUS): Remove some simplifications
+	from here.
+	* cse.c (simplify_binary_operation, case PLUS, MINUS): Put these

+
+	* cp-parse.y (stmts): Fix parsing rules to match C++ semantics
+	better (and hence give the compiler better error recovery).
+
+Thu Oct 17 19:31:15 1991  Ken Raeburn  (raeburn at cygnus.com)
+
+        * cp-pt.c (tsubst): For NEGATE_EXPR, call build1, not build.
+        Handle NOP_EXPR likewise.
+        (unify, case TEMPLATE_CONST_PARM): Copy value to permanent obstack.
+
+        * cp-method.c (PARM_CAN_BE_ARRAY_TYPE): If not already defined,
+        define it to be 1.
+        (build_overload_name): Test to see if it's nonzero, rather than
+        whether it's defined; this permits compilation options to disable
+        it, but leave it enabled by default.  Add one to the array size,
+        since the value retrieved appears to be the maximum index, not the
+        true array size.
+
+Thu Oct 17 19:15:37 1991  Mark Eichin  (eichin at tweedledumber.cygnus.com)
+
+        * cp-pt.c (instantiate_class_template):  has an argument to
+        indicate whether to setup for parsing or not. (All existing cases
+        did a feed input, but if we are trying to set up intermediate nodes
+        while waiting for the parser to return to a template_instantiate
+        site we need to suppress the parsing part of it, which will get
+        redone later.)
+        (tsubst): under case UNINSTANTIATED_P_TYPE, actually instantiate any
+        class templates that are needed for function return values, and set
+        them up as pending templates to be run later.
+
+        * cp-parse.y (primary): since build_x_function_call doesn't
+        require a complete type any more in certain cases, we instantiate
+        any pending templates and then require_complete_type on the
+        remainder. 
+
+        * cp-typeck.c (build_function_call_real): added an argument to
+        optionally skip the require_complete_type... implicit template
+        instantiation has to be postponed, so we won't get a complete type
+        until the parser can grab it.
+
+        * cp-call.c (build_overload_call_real): added an argument do
+        allow choice of build_function_call_maybe or build_function_call
+        based on whether we thought we would require a complete type out of
+        build_function_call. 
+
+Wed Oct 16 09:06:57 1991  Tom Wood  (wood at dg-rtp.dg.com)
+
+	* c-decl.c (store_parm_decls): Fix and disable recording the arg
+	type list for the function indicating the number of arguments.
+	* c-typeck.c (self_promoting_args_p): Allow the arg type to be null.
+
+	* expmed.c (store_bit_field, extract_bit_field): Add checks for
+	MEM_IN_STRUCT_P if the structure reference is a MEM.
+
+Tue Oct 15 18:37:50 1991  Ken Raeburn  (raeburn at cygnus.com)
+
+        * cp-call.c (build_overload_call): If template match fails, still
+        set function field of candidate structure, and set bad_arg field to
+        new magic number -4 to indicate failed type unificiation.
+
+        * cp-class.c (add_method): Call make_function_rtl only if not
+        processing a template declaration.
+
+        * cp-tree.def: New node type, UNINSTANTIATED_P_TYPE, for
+        parameterized types that haven't had parameters filled in yet.
+        Looks like a type node.
+
+        * cp-decl.c (struct binding_level): New flag indicating any name
+        should be accepted when looked up at this level.  This is a kludge
+        to try to deal with methods of parameterized types.
+        (declare_uninstantiated_type_level): Set it.
+        (uninstantiated_type_level_p): Return it.
+        * cp-class.c (pushclass): If the "class" type is
+        UNINSTANTIATED_P_TYPE, flag it in the new binding level.
+
+        * cp-decl.c (push_overloaded_decl): New argument to indicate
+        whether the decl should be forgotten when the current level is
+        exited.  Callers changed.
+        (push_overloaded_decl_top_level): Ditto.
+        (dont_forget_overload): Deleted.
+        (push_overloaded_decl_1): New fn; like push_overloaded_decl, but
+        never forgets.  Intended only for use by auto_function macro.
+        (auto_function): Use it.
+
+        * cp-decl.c (print_binding_level): Print type-shadowed field at
+        each level.  Skip fields with no values.
+
+        * cp-decl.c (adjust_type_value): Use SET_IDENTIFIER_TYPE_VALUE,
+        not set_identifier_type_value.
+
+        * cp-decl.c (pushdecl): Undo Oct 4 back-out of previous change.
+        Set type value of name of passed decl, instead of name of type in
+        passed decl.
+        (pushdecl_top_level): Search type-shadowed fields of outer binding
+        levels, munging outermost one if found to cause it to "restore" the
+        new global value.
+
+        * cp-decl.c (push_overloaded_decl): Don't punt second or later
+        templates of a given name.
+
+        * cp-decl.c (start_decl): Template-handling code moved up, to
+        cope better with variable declarations.  Don't check for incomplete
+        type or constructor requirements when processing template.
+
+        * cp-decl2.c (build_push_scope): If passed error mark node, just
+        return it.
+        (constructor_name): Handle UNINSTANTIATED_P_TYPE.
+
+        * cp-lex.c (identifier_type): Don't return PTYPENAME for function
+        template name.
+
+        * cp-method.c (report_type_mismatch): New magic bad-arg value -4
+        indicates type unification failure.
+        (build_overload_name, case UNINSTANTIATED_P_TYPE): Handle like other
+        template-related types that shouldn't get visibility outside the
+        compiler.
+
+        * cp-parse.y (template_type): Use IDENTIFIER_TYPE_VALUE from
+        name, if expansion doesn't happen.
+        (tmpl.1, tmpl.2): Now type <ttype>.  Value is null or return value
+        from instantiate_class_template.
+        (template_instantiation): Always put copy of decl in global scope.
+        Use pushdecl_top_level instead of setting IDENTIFIER_GLOBAL_VALUE
+        slot.
+        (LC): If type has been or is being defined, push a new type with the
+        same name, to avoid conflict.
+        (try_for_typename): New type <itype>.  Value is non-zero iff type to
+        be pushed uses no template parms and isn't error_mark_node.
+        (scoped_id): Return error_mark_node for template parameter uses, and
+        leave error_mark_node alone.  Only pop class if try_for_typename
+        value is non-zero.
+        (scoped_typename): Ditto.
+
+        * cp-pt.c (end_template_decl): If template decl/class head arg is
+        null, punt.  For non-type templates that didn't come in as template
+        decls, clear public flag.  Such cases shouldn't arise any more; just
+        put in abort call for now until we're sure.  Comment out code for
+        forcibly removing temporary values of template type parms; Michael
+        broke the code and fixed the original problem.  Handle error case
+        where decl to be pushed might be null.
+        (coerce_template_parms): Handle arg list as TREE_VEC as well as
+        TREE_LIST.  If arg list uses template parms, return
+        UNINSTANTIATED_P_TYPE node.
+        (uses_template_parms, case UNINSTANTIATED_P_TYPE): Return 1.
+        (instantiate_class_template): Now returns tree -- error_mark_node or
+        NULL_TREE or class type; callers and decls changed.  Assign
+        TYPE_NAME field when building new RECORD_TYPE and TYPE_DECL nodes.
+        Don't need to do extra poplevel any more.
+        (tsubst): Handle UNINSTANTIATED_P_TYPE, MINUS_EXPR, PLUS_EXPR,
+        NEGATE_EXPR.
+        (undo_template_name_overload): Don't need to explicitly clear type
+        field any more.
+        (overload_template_name): Push a TYPE_DECL, instead of explicitly
+        setting type value field.
+        (end_template_instantiation): Don't need to pop a level any more.
+        (reinit_parse_for_template): Throw away saved block for null or
+        error template node.
+        (type_unification): Handle variadic functions, and functions with
+        default values for arguments.
+        (unify): Handle TREE_VEC and UNINSTANTIATED_P_TYPE.
+
+        * cp-ptree.c (print_lang_type): Handle UNINSTANTIATED_P_TYPE.
+
+        * cp-tree.h (push_overload_decl): Declare here, not in
+        cp-decl.c.
+        (TEMPLATE_TYPE_* macros): Delete unused (and now incorrect)
+        versions.

+	accessed via their CLASSTYPE_ASSOC field.
+
+	* cplus-tree.h (lang_type): Delete fields OFFSET,
+	MAIN_CLASS_VARIANT, NEXT_CLASS_VARIANT, VIA_PUB_OR_VIRT.

+	the assoc for the type.
+	(CLASSTYPE_VIA_*, SET_CLASSTYPE_VIAS): Deleted.
+	(CLASSTYPE_OFFSET*): Deleted.
+	(CLASSTYPE_N_BASECLASSES): Now uses type's assoc.  TYPE_BASETYPES
+	field is unused.  Next change will make TYPE_BASETYPES hold the
+	assoc field.
+	(CLASSTYPE_VBASE_SIZE): Use slot in TYPE_LANG_SPECIFIC instead of
+	sneaking it into the TREE_TYPE field of the basetypes.
+
+	(ASSOC_TYPE): Deleted.  Now use ASSOC_VALUE everywhere.
+	(ASSOC_{BASETYPE,BASETYPES}): New macros.  Both are operations on
+	assocs and return assocs.
+	(CLASS_ASSOC_BASETYPE): New macro.  This performs roughly the same
+	function that CLASSTYPE_BASECLASS used to, but it retains no assoc
+	info in the type it returns.
+	(ASSOC_NEXT_ASSOC): New macro used for traversing assoc chains built
+	up by search routines.
+	(ASSOC_VIA_{PUBLIC,VIRTUAL}): New macros for accessing inheritance
+	information.  CLASSTYPE_VIA_{PUBLIC,VIRTUAL} no longer used.
+	(ASSOC_CID): New macro.

+	(DECL_ANON_UNION_ELEM): Deleted.  Now anonymous union decls are
+	distinguished as FIELD_DECLs with NULL DECL_NAMEs and UNION_TYPE

+	relationships (get_base_type and get_base_distance) to use this macro.

+	* cplus-type2.c (basetype_or_else): Change interface to use/return an
+	assoc instead of a type.  Change name to base_assoc_or_else.
+
+	* cplus-tree.c (build_classtype_variant): Deleted.
+	(copy_type_lang_specific): Deleted.
+	* all cplus-* files: Everything that used to use CLASSTYPE_OFFSET on
+	types now uses ASSOC_OFFSET on assocs.
+
+	* cplus-class.c (propagate_basetype_offsets): Change interface to use
+	assocs instead of types.  Change name to propagate_assoc_offsets.
+	* cplus-search.c (get_base_type): Ditto; name changed to

+	ASSOC_BASEINIT_MARKED instead of CLASSTYPE_MARKED6.
+	(finish_base_struct): New argument ASSOCS is the list of assocs that
+	describe the basetypes of T.
+
+	* cplus-tree.c (make_lang_type): Always initialize
+	CLASSTYPE_VBASE_SIZE to integer_zero_node.  To test if a class has
+	virtual baseclasses, test CLASSTYPE_VBASECLASSES, not
+	CLASSTYPE_VBASE_SIZE.
+
+	* cplus-class.c (finish_struct): Rewritten to use assocs instead of
+	types where appropriate.
+
+	* cplus-search.c (get_base_distance): Change interface to use assocs
+	or types.  Also, PATH_PTR argument is now an assoc chain, not a
+	TREE_LIST.  Algorithm to find leftmost path is now more efficient.
+	(compute_visibility): Uses assoc chain instead of TREE_LIST of
+	types.
+	(recursive_bounded_basetype_p): New function.
+	(dfs_walk, dfs_* functions): Change to be called with assocs instead
+	of types.
+	(breadth_first_search, all bfs_*): Ditto.

+	on assoc chains.
+
+	* cplus-class.c (build_vtable, prepare_fresh_vtable,

+	instead of types.  Use macro ASSOC_VTABLE_PATH_MARKED on the assocs
+	instead of CLASSTYPE_MARKED3.  Use macro ASSOC_NEW_VTABLE_MARKED on
+	the assocs instead of CLASSTYPE_MARKED4.
+
+	* cplus-dbxout.c: Now needs to know more about assocs.  When assocs
+	are put in the TYPE_BASETYPEs field, it should not need to know
+	about lang_type.
+
+	* cplus-decl.c (xref_tag): Rewritten to build proper assoc lists.  No
+	longer builds basetype lists.
+	(finish_function): Make `flag_no_inline' really take effect.
+
+	* cplus-tree.c (make_assoc): Changed for new assoc structure.  The
+	fields in assocs are now: VALUE (pointer to TYPE that this assoc is
+	for), OFFSET (the byte offset of this basetype in the whole object),
+	VTABLE (the virtual function table that should be used to initialize
+	objects controlled by this assoc), VIRTUALS (the virtual functions
+	to use for initializing VTABLE), BASETYPES (a TREE_VEC of basetypes
+	that this assoc has, or NULL_TREE if none), NEXT_ASSOC (a temporary
+	slot used to point to the next assoc in an assoc chain),
+	VIA_{PUBLIC,VIRTUAL} bits saying whether this assoc is a basetype of
+	its parent via public or virtual inheritance.
+
+	* cplus-ptree.c (print_lang_type): Modified as necessary to cope with
+	new inheritance structure.
+
+	* cplus-search.c (get_base_type_1): This function was unused and
+	wrong.  Deleted.
+
+	* cplus-tree.c (layout_basetypes): Take new arg ASSOCS.  Layout the
+	basetypes my modifying the assocs, not the types.
+	(layout_vbasetypes): Ditto.
+
+	* all cplus-* files: Removed dead code, unused variables, and change
+	asserts where appropriate.
+
+	* all cplus-* files: DECL_VIRTUAL_P is no longer used as a truth test
+	for whether or not a function is virtual.  Use a test for non-NULL
+	DECL_VINDEX instead.

+	* cplus-decl.c (start_decl): When constructing a decl tree for a
+	function template, copy last_function_parms to permanent storage,
+	and save it as the function argument list.  Call build_lang_decl
+	instead of build_decl, instead of duplicating the extra work it does.
+	Set `overloaded' flag to 1.  Call dont_forget_overload, so the
+	template decl won't get discarded.
+	Also deleted some commented-out code.
+
+	* cplus-pt.c (uses_template_parms, cases VAR_DECL, FUNCTION_DECL):

+
+	* genemit.c (gen_expand, main): Change FAIL macro to be a simple

+
+	* cplus-input.c (getch): Rewritten slightly to help GNU C optimizer.
+	* cplus-lex.c (yylex): In IDENTIFIER case, pre-test condition that
+	`getch' tests, and call `getc' directly when possible.  This cuts

+
+	* cplus-class.c (add_virtual_function): Memoize the first 256
+	virtual function table index nodes (0x80000001, 0x80000002, etc.).
+	(finish_struct): Use `size_int' instead of `build_int_2' when we
+	know the int will not be changed in place (such as the size value of
+	virtual function tables).
+	* cplus-decl2.c (finish_table): Same change as for `finish_struct'.
+	* cplus-tree.c (layout_basetypes): Same change.
+	* cplus-decl.c (init_decl_processing): Use `size_int' to initialize

+
+	Merge some VMS changes from 1.39 that did not make it to 2.0.

+	will be.

+	to create it, and fail if the mkdir fails.

+Tue Jul 23 13:15:43 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* xm-i386.h, xm-i860.h, xm-spur.h, xm-tahoe.h: Use __builtin_alloca.
+
+Tue Jul 23 12:26:01 1991  Michael Tiemann  (tiemann at cygint.cygnus.com)
+
+	* function.c (instantiate_virtual_regs_1): Change dubious code that
+	used to assign NEW to XEXP (x, 1) regardless of whether

+	I.e., if the rtx is out of range and OBJECT is NULL, don't make any
+	change at all.
+
+	* out-sparc.c (compute_frame_size): If a function has any
+	stack-local objects, it's frame size is non-zero and space must be
+	reserved for the register window.
+
+	* loop.c (loop_optimize): Use get_max_uid to compute max_uid_for_loop.

+	only eligible for leaf-function epilogue delay slots.
+
+Tue Jul 23 11:52:50 1991  Michael Meissner  (meissner at geech.gnu.ai.mit.edu)
+
+	* dbxout.c (dbxout_symbol): Correct typo in getting static member

+
+Tue Jul 23 07:10:41 1991  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
+
+	* varasm.c (immed_double_const): Use CONST_INT if MODE fits within

+
+	* version.c: Bumped to 1.94 because of significant changes to

+
+Sun Jul 21 18:45:57 1991  Richard Stallman  (rms at mole.gnu.ai.mit.edu)
+
+	* toplev.c (rest_of_compilation):
+	Save and restore DECL_INITIAL if we use save_for_inline_copying.
+	* integrate.c (save_for_inline_copying): Really copy DECL_INITIAL.
+	Calling integrate_decl_tree doesn't do it; deleted that call.

+	(integrate_parm_decls): Renamed from copy_parm_decls.

+
+	* expmed.c (store_fixed_bit_field): Pass actual bit position (including

+	Use failure of get_best_mode to indicate that field spans word 
+	boundary.
+	Pass actual bit position to store_split_bit_field.

+	bitpos > BITS_PER_WORD.
+	Abort if BITPOS and BITSIZE don't cross exactly one word boundary.

+
+Sun Jul 21 06:11:55 1991  Michael Tiemann  (tiemann at cygint.cygnus.com)
+
+	* All cplus-* files: DECL_VIRTUAL_P is no longer applied to
+	FUNCTION_DECLs.  Instead, to test if a function is virtual or not,
+	it suffices to test whether its DECL_VINDEX is non-NULL.  We use
+	ERROR_MARK_NODE as the placeholder for a FUNCTION_DECL we know will
+	be virtual, but for which we don't yet know the actual index.
+
+	* cplus-decl.c (define_function): Don't set up DECL_ASSEMBLER_NAME
+	until after having the chance to call through PFN.  Since `pushdecl'
+	now keys off of DECL_ASSEMBLER_NAME, we don't want to create

+	the inline code calls longjmp.
+
+	* function.h (struct function): New field `calls_longjmp'.
+
+	* out-i386.c (simple_386_epilogue):  Add function description.
+	Return 0 if NON_SAVING_SETJMP && `setjmp' is called in function.
+
+	* tm-i386v.h (NON_SAVING_SETJMP): New macro.
+	(FRAME_POINTER_REQUIRED): New macro.

+
+	* tm-m88k.h (OPTIMIZATION_OPTIONS): Don't change flag_signed_bitfields.
+
+	* cccp.c (include_defaults) Use LOCAL_INCLUDE_DIR macro instead
+	of "/usr/local/include".  Provide default definition.
+
+	* cccp.c (include_defaults) Added INCLUDE_DEFAULTS macro to
+	provide complete control over default include directories.
+	Delete the special case for VMS.
+	* xm-vms.h (INCLUDE_DEFAULTS): Defined.
+
+	* proto-man: Renamed from proto-unproto.1.
+
+	* final.c (final_scan_insn): Do ASM_OUTPUT_LOOP_ALIGN only for real loop.
+
+Sat Jul 20 05:34:13 1991  Michael Tiemann  (tiemann at cygint.cygnus.com)
+
+	* tree.h (tree_type): Use the MAXVAL slot for TYPE_METHODS.
+	* cplus-class.c (finish_struct): Methods are now chained with
+	TREE_CHAIN and placed in the TYPE_METHODS of their _TYPE node.
+	* cplus-dbxout.c (dbxout_type_methods): Use this fact, instead of
+	using more C++-specific knowledge.
+
+	* cplus-decl.c (init_decl_processing): Variable
+	`const_ptr_type_node' was not being initialized.  Same with
+	`const_string_type_node'.
+
+	* tree.h (DECL_PRINT_NAME): Marked for death.
+	(DECL_ASSEMBLER_NAME): Changed from a char* to a tree node.
+	All front-end files changed as necessary.
+
+	* cplus-tree.h (DECL_ORIGINAL_NAME): Deleted.  Now we use
+	DECL_NAME.
+	(DECL_NAME): No longer means the mangled name.  Now we use
+	DECL_ASSEMBLER_NAME for that purpose.
+	All cplus-* files changed as necessary.
+
+	* cplus-tree.c (lang_printable_name): Use a ring-buffer to hold
+	printable names instead of DECL_PRINT_NAME slot of a _DECL node.
+
+	* collect2.c: #define COLLECT, and let config.h provide definition
+	of macros.
+

+	overlap the load.
+	(andsi3, iorsi3, xorsi3): Replace logical define_insn's with
+	define_expand's that either map directly to the hardware
+	instruction, or have a clobbered register to load the large
+	constant into.  This is instead of using $1 to hold the
+	intermeidate value.  Set the safe attribute to yes for the cases
+	where we need to load the integer.  Add define_split's to break
+	the large logical operations into the separate pieces.

+	defined, use it to split the floating point value into 2 long
+	integers, and print them out in hex.  Otherwise use .double.
+	(mips_output_float): If REAL_VALUE_TO_TARGET_FLOAT is defined, use
+	it to split the floating point value into a long integer, and
+	print in out in hex.  Otherwise use .float.

+	product (as opposed to the OSF/1 reference port from OSF).

+
+	* decstatn.h (CPP_PREDEFINES): If CPP_PREDEFINES is defined, don't

+
+	* gstdarg.h (va_list) [__svr4__]:  Typedef it to `void *'.
+	* va-sparc.h (__va___list) [__svr4__]:  Typedef this as `void *'.

+
+	* calls.c (stack_arg_under_construction): New variable.
+	(store_one_arg): Set stack_arg_under_construction before calling
+	expand_expr if expand_expr might call a constructor to initialize
+	a stack argument.
+	(expand_call): Push the stack around function calls if
+	stack_arg_under_construction is nonzero.
+	Also copy structure_value_addr in that case.
+	Push the stack around an inline function if it makes calls
+	and there are outgoing arguments on the stack which must be preserved.
+	Move the call to expand_cleanups_to before that.
+	Do this stack adjustment before computing argument locations.

+        (dwarfout_file_scope_decl):  Check input node to see if it is an
+        ERROR_MARK before checking for DECL_IGNORED_P.  Also makes sure that
+        any node marked as DECL_IGNORED_P isn't also a function definition.

+
+	* merge in Cygnus changes...
+
+	Thu Apr 16 12:23:06 1992  Mike Stump  (mrs@rtl.cygnus.com)
+
+	* cp-call.c (build_method_call): propagate const around to avoid an
+	incorrect error message.  This type of fix may now be necessary in
+	other parts of the compiler.  This solves all but one known const
+	problems.
+
+	Wed Apr 15 14:18:27 1992  Mike Stump  (mrs@rtl.cygnus.com)
+
+	* cp-type2.c (readonly_warning_or_error):  because the compiler
+	is now warning about const alot more, for a release or two,
+	lets just warn about const problems, just in case it is a compiler
+	problem and not a user problem.
+	
+	* cp-cvt.c (build_up_reference): Lets get tougher on const problems
+	on COMPONENT_REFs.
+
+	Wed Apr 15 11:59:42 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)

+
+	Tue Apr 14 11:44:32 1992  Mike Stump  (mrs@rtl.cygnus.com)
+
+	* cp-decl.c (start_decl):  Shouldn't use flag_this_is_variable
+	to make what this points to const, but I don't have the heart
+	to do it right now.
+	
+	* cp-decl2.c (grokclassfn):  Don't use flag_this_is_variable
+	to make what this points to const.
+
+	* cp-typeck.c (convert_arguments):  Let build_up_reference handle
+	const errors correctly.  Removes April 10 change.
+	
+	* cp-cvt.c (build_up_reference):  Don't let people subvert const
+	when passing const argements to non-const functions.
+
+	* cp-tree.c (build_cplus_method_type): Don't use
+	flag_this_is_variable to make what this points to const.
+
+	From Wed Apr  1 12:00:59 1992  Chip Salzenberg  (chip at tct.com)
+
+        * cp-class.c (import_export_vtable): New function to set
+          TREE_PUBLIC and/or TREE_EXTERNAL on vtables.
+          (build_vtable): Use it.
+          (prepare_fresh_vtable): Use it.
+
+        * cp-decl.c (finish_decl): Don't assume that TREE_PUBLIC means
+          "exported"; it can mean "imported".  Decide with TREE_EXTERNAL.
+          (finish_function): Ditto.
+        * cp-decl2.c (write_vtable_entries): Ditto.
+          (finish_vtable_typedecl): Ditto.
+          (finish_vtable_vardecl): Ditto.
+          (finish_file): Ditto.
+
+        * cp-lex.c (set_vardecl_interface_info): Public objects always
+          have TREE_PUBLIC, whether exported or imported.

+
+
+	Fri Apr 10 21:44:15 1992  Per Bothner  (bothner@cygnus.com)
+
+	* cp-method.c (build_overload_name): Mangle 'signed char'
+	as 'Sc' (i.e. differently from 'char'!).
+
+	Fri Apr 10 17:38:04 1992  Mike Stump  (mrs@cygnus.com)
+
+	* cp-typeck.c (convert_arguments): don't allow people to wipe const.
+
+	Thu Apr  9 18:28:36 1992  Mike Stump  (mrs@rtl.cygnus.com)
+
+	* cp-tree.h:  Add entry for $vb and $vf so that NO_DOLLAR_IN_LABEL
+	works.
+	* cp-class.c (finish_struct):  Use the new macros from cp-tree.h.

+
+	Thu Apr  9 02:11:01 1992  Mike Stump  (mrs@rtl.cygnus.com)
+
+	* cp-typeck.c (build_function_call_real): Merge in a change made to
+	the C front end into the C++ front end to handle volatile functions.
+
+	Thu Apr  9 03:45:03 1992  Mark Eichin  (eichin at cygnus.com)
+
+	* cp-class.c (finish_struct): sanity check before calling popclass.
+	If we're already hosed due to previous parse errors (specifically,
+	we're not inside a class anymore) just report an error rather than
+	crashing in popclass (if there wasn't a previous parse error, as the
+	message suggests, we should get reports; this closes gcc/p0000525.)
+
+	Wed Apr  8 08:56:49 1992  Mike Stump  (mrs@rtl.cygnus.com)
+
+	* cp-decl.c (grokdeclarator): Fix an eichin bug introduced seconds
+	ago.  Shame, he didn't put:
+
+	Workaround for p869:
+        1) grokdeclarator (around cp-decl.c:7462) is using popclass(1)
+        uses popclass(1) to close the pushclass(3) done by
+        build_push_scope; however, it's coming around another time and
+        popping all the way out, which leads to the core dump when
+        do_friend is called from global scope (do_friend uses
+        current_class_name to figure out whose friendship it is
+        bestowing.) Current workaround: if (friendp) don't allow
+        popping all the way out. We still need to figure out how to
+        make sure it only gets called the *right* time; we also need
+        to figure out if the correct scope is being used, but that's a
+        matter of regression testing.
+
+	into a ChangeLog entry.

+	Wed Apr  8 01:10:44 1992  Mike Stump  (mrs@rtl.cygnus.com)
+
+	* cp-decl.c: Cleanup binding_levels_sane related code.  Deleted
+	argument, and changed to void type.  Removed extraneous asserts.

+
+	* mips.c (output_movstrsi): If one of our temporary registers is
+	used as an address register, don't use it and emit a warning.  This

+
+	* dwarfout.c: Add default definition for ASM_OUTPUT_ASCII

+	(pushdecl): use set_identifier_type_value so that the local value
+	actually gets erased when we leave this level. Changed code that
+	checks for global_binding_level to recognize that if
+	class_binding_level is set, we're not in the global one.
+	(poplevel_class): restore shadowed list too, like poplevel does.
+	(print_binding_level): added no_print_functions and

+	directive.
+	(ENCODE_SECTION_INFO): Encode function labels.
+	(ASM_OUTPUT_LABELREF): Deal with function labels.
+	(ASM_OUTPUT_REG_PUSH, ASM_OUTPUT_REG_POP): Don't do anything for
+	now; their only use (saving stuff during profiling) interacts in a
+	wierd way with required assembler directives at the start of a
+	function.  Instead, do the save and restore in the function
+	prologue.
+	(hppa_encode_label): Declare.
+	* pa-hpux.h, pa-ghpux.h (TARGET_DEFAULT): Link against shared
+	libraries.
+	(LINK_SPEC): Don't link against shared libraries if debugging or

+	hold information for multiple save/restore insns.  New variable
+	hard_regs_need_restore.
+	(choose_hard_reg_mode): New argument `nregs' indicating how many
+	hard registers are desired.  All callers changed.
+	(init_caller_save): Change initialization to handle multiple
+	register saves.  A call-used register can not be live across
+	if we can not find a single register mode to save it in.
+	(multiple register saves are optional)
+	(init_save_areas): Change initialization of regno_save_mem to
+	handle multiple register saves.

+	Set hard_regs_need_restore to hard_regs_saved after crossing

+	(set_reg_live, clear_reg_live): Do the right thing for 
+	hard_regs_need_restore and hard_regs_saved.
+	(restore_referenced_regs): Just return if X is a clobber.

+	register from the save area.
+	(insert_save_restore): Now returns the number of extra registers
+	saved/restored.  New argument `maxrestore' which constrains how
+	many hard registers should be restored.  All callers changed.
+	Do stores of consecutive registers with double store insns if
+	possible.  Else do them with single word insns. Likewise for
+	loads, except constrained by maxrestore.  Set hard_regs_saved
+	and hard_regs_need_restore appropriately to minimize useless
+	saves into the save area.  Test against	hard_regs_need_restore
+	when trying to restore multiple regs and similarly test against
+	hard_regs_saved when storing multiple regs.

+	(ASM_FINAL_SPEC): Use %U to get the last file name created with
+	%u, rather than %u.
+	(ARG_POINTER_REGNUM): Use the hardwired register $0 as the
+	argument pointer, instead of the frame pointer, to allow the frame
+	pointer to be the same as the stack pointer after the initial
+	stack allocations.  This is to allow GCC generated code to be
+	linked against MIPS shared libraries.  The linker rearranges the
+	code, and needs to have a frame pointer, if used, to be the same
+	as the stack.  The argument pointer is always eliminated in favor
+	of the stack pointer or frame pointer.
+	(FRAME_GROWS_DOWNWARD): Don't define this any more.
+	(STARTING_FRAME_OFFSET): Locals start after the stack area to pass

+	frame pointer, since they are now separate.

+	(mips_debugger_offset): Add support for the frame pointer being
+	the same as the stack pointer, instead of being the same as the
+	argument pointer.  Abort if the address is not based on any of the
+	stack, frame, or argument pointers.
+	(print_operand_address): Add checks for the arg pointer not being
+	eliminated.

+	(function_epilogue): Strip leading '*' if it exists from
+	current_function_name when printing statistics.  Delete increment
+	of number_functions_processed.
+	(compute_frame_size): Don't base extra_size on the macro
+	STARTING_FRAME_OFFSET.  If function is a leaf function, but calls
+	__builtin_alloca, allocate an arg area, so that the MIPS linker
+	will not complain about creating a second frame pointer.  Move the
+	argument save area beneath local variables.
+
+	* decrose.h (ASM_FINAL_SPEC): Use %U to get the last file name
+	created with %u, rather than %u.
+
+	* gcc.c (do_spec_1): Add %U to return the last name generated with

+	file.

+
+	* gcc.c (process_command): Don't set verbose_flag if they make a

+
+	* pa.h (ASM_FILE_START): If profiling IMPORT "_mcount" instead of

+
+	* cp-tree (break_out_calls): Only make ony copy of a node on

+
+	* cp-decl.c (grokdeclarator): In SCOPE_REF case, sort out visibility

+

+	conditions on systems with 64 bit integers.
+	(mips_move_1word): Just use li to load constants that can be done
+	with lui, instead of issuing the lui, since the GAS bug that
+	generated two instructions has been fixed.
+	(final_prescan_insn): Move the checking for filling the delay
+	slots here from the FINAL_PRESCAN_INSN macro.
+
+	* mips.md (andsi3, iorsi3, xorsi3): Make the constraints match
+	the real machine (the predicate still is more general in order
+	to optimize bitfields at the expense of not CSE'ing large
+	constants used in logical ops, and making reload load it into
+	a scratch register).  Don't use $1 as a temporary register any
+	more.
+
+	* varasm.c (decode_reg_name): If `memory' return -4.
+
+	* stmt.c (expand_asm_operands): If `memory' is used as a clobbered
+	register, emit a (clobber (const_int 0)) to force the compiler not
+	to cache memory values in registers across the assembly
+	instruction(s).
+
+	* mips-tfile.c (read_line): Semicolons within strings are not
+	counted as statement separators.
+
+	* collect2.c (scan_prog_file, OSF/rose case): Cast pointer arguments
+	to bcopy to generic * to avoid warnings.
+
+Thu Jun 18 12:04:53 1992  David J. MacKenzie  (djm@wookumz.gnu.ai.mit.edu)
+
+	* c++: If given -v with no file args, don't pass the libraries to
+	gcc.
+
+Thu Jun 18 10:34:22 1992  Tom Wood  (wood@dg-rtp.dg.com)
+
+	* expr.c (expand_builtin, BUILT_IN_FSQRT): Emit queue of increment
+	instructions before starting a sequence that may get thrown away.
+
+See ChangeLog.5 for earlier changes.

+	rejects any const_double.
+	(CONST_DOUBLE_OK_FOR_LETTER_P): Change.  New defs are 'G' == low
+	word all zeros, 'H' == high word all signs.
+	(EXTRA_CONSTRAINT): New. 'Q' == volatile memref.  Used to generate
+	cache-bypass instructions when -mvolatile-nocache is set.
+	(RETURN_POPS_ARGS): Change, always true.
+	(FUNCTION_ARG_ADVANCE): Count args, not # words of args.
+	(FUNCTION_ARG): Return arg count to the final VOIDmode FUNCTION_ARG
+	hack that supplies "next arg register" to be stored in call insn.
+	(TRAMPOLINE_TEMPLATE): Use instruction notation rather than constants.
+	(INITIALIZE_TRAMPOLINE): Use gen_call_pop.
+	(LEGITIMATE_CONSTANT_P): Rewrite to make clearer.
+	(GO_IF_LEGITIMATE_ADDRESS): Do not use indirect addressing -- with
+	insn scheduling, two loads can be faster and can't be slower.
+	(SLOW_BYTE_ACCESS): Define unless C2.  Memory access to bytes is
+	not actually slow, but faster processors don't forward partial
+	word writes to word reads, and setting SLOW_BYTE_ACCESS
+	makes the code consistently use word ops where possible.
+	(CONST_COSTS): Const_DOUBLE cost is zero -- if it appears, it is
+	immediate and therefore free.
+	(RTX_COSTS): areg+const is free (via indexing).
+	(RTX_COSTS): Provide target-dependent values for *,<<,>>
+	(ADDRESS_COST): Zero.  Indirect addresses are no longer used.
+	(ADJUST_COST): Define.
+	(TARGET_FLOAT_FORMAT): Define as VAX_FLOAT_FORMAT.  Also
+	accurately describes the semantics (not the bit pattern)
+	of convex ieee mode.
+	(REAL_VALUE_ATOF): Define, to prevent real.c from constructing
+	vax dfloats.  Apparently it doesn't do gfloat.
+	(CHECK_FLOAT_VALUE): Call convex.c.
+	(ASM_FILE_START): Output appropriate .fpmode pseudo op.
+	(ASM_IDENTIFY_GCC): Ouput a zero after gcc2_compiled to keep it
+	from hiding the real name from profilers and adb.
+	(ASM_OUTPUT_DOUBLE, _FLOAT): Use hex to avoid /bin/as conversion 
+	errors.
+	(ASM_DECLARE_FUNCTION_NAME): Define; call convex.c.
+	(PRINT_OPERAND, _ADDRESS): Call convex.c.
+	(EXIT_BODY): Define for libgcc2.  Call atexit handler if present.
+	
+	convex.md: Add scheduling info.
+	(movxx): One of the operands must be a register.
+	(movdf, movdi):	Add anonymous patterns that can load an arbitrary 
+	const_double by doing two immediate loads.  This is not superior
+	to loading it from memory, and can be worse, so LEGITIMATE_CONSTANT_P
+	still rejects these constants, but the patterns are still useful
+	so rtx folding can produce arbitrary results.
+	(floatunsdidf, floatunsdisf): Add patterns that avoid double rounding.
+	(floatunssidf, floatunssisf): Add patterns that mimic gcc's default
+	method, to keep SI cvts from promoting to the above DI cvts.
+	(fix_truncdfsi2): Use cvtd.l even if cvtd.w is available -- on c34
+	cvtd.w is microcoded and slower.
+	(addqi3, subqi3, mulqi3): can do immediate with word insn.
+	(subsi3): use sub/neg to get reverse subtract (reduces reg shuffling).
+	(udivsi3): give up on having sign_expand_binop do this; people keep
+	breaking it.  Manually extend unsigned SI to signed DI, then divide.
+	(xshfxx3): The options rank differently on different machines, so 
+	spell them all out and enable the appropriate ones under TARGET_Cxx.
+	(sqrtxx2): Put under flag_fast_math.
+	(sinxx2, cosxx2): I don't know why these exist, but they do, so supply
+	them.  The other microcoded intrinsics are in convex math.h.
+	(txtxx): Remove, no longer necessary.
+	(cmpdi): Add alternative to fake "eq.l #0,sk" with "neg.l sk,scratch".
+	(cmpqi): Omit, seems to produce marginally better cse than the old way.
+	(cmpsf): Avoid compare against 0.0 in ieee mode, since -0.0 is 
+	possible and would confuse old ucode.
+	(movstrsi): Add.
+	(anon): Add patterns to pick up on dbra optimizations and implement the
+	sub/test part.  (This optimizes out the compare against 0.)
+	(call, call_value): Use _pop form instead, and let convex.c replace
+	the pushes with fp stores.
+	(end): Put local variable list back.
+
+	convex.c (init_convex): New. Fill in tables used by convex.h.
+	(psw_disable_float): New.  Turn off float exception enables to
+	make the environment more ieee-like.
+	(set_cmp): Change name to output_cmp.
+	(gen_cmp): Change name to output_condjmp.  Add handling for
+	`neg.x' as a fake `eq.x #0' and for optimized-out compares
+	that read the carry of a preceding decrement.
+	(simplify_for_convex): New.  Replace addr-(-const) with
+	addr+const so /bin/as will like the notation.
+	(expand_movstr): New.  Generate pipelined load/store sequence.
+	(asm_declare_function_name): New. Output arg count for debuggers.
+	(print_operand): Moved from convex.h.  Add %u and %v to fetch
+	subwords of a CONST_DOUBLE, %z to use in replacing shift by mul.
+	(print_operand_address): Moved from convex.h.
+	(outfloat): New, call REAL_VALUE_TO_DECIMAL.
+	(replace_arg_pushes): New.  Replace sp by fp if possible; this does
+	not allow us to get rid of sp but stores are faster than pushes on
+	new machines.
+	(emit_ap_optimizations): New.  Do simple live analysis of arg pointer
+	register and eliminate dead reloads.
+	
+	math-convex.h: removed.
+	fixinc.convex: new file.

+
+	* cp-method.c (build_overload_nested_name): Use DECL_NAME instead of

+	not error_with_decl, inside code that's only ever reached with
+	-Woverloaded-virtual.
+
+	* cp-typeck.c (c_expand_return): When building the INIT_EXPR, clear
+	out the context if it's an ERROR_MARK so the back-end won't die later.
+
+	* cp-type2.c (my_friendly_abort): Don't say anything like "please
+	fix above errors", just exit quietly.
+
+	* cp-lex.h (enum rid): Reordered for improved speed in grokdeclarator
+	when it does its linear search.  RID_WCHAR is no longer in the
+	search path, since it's found by hand (as are RID_INT and RID_CHAR).
+	(RID_FIRST_MODIFIER): Start at RID_EXTERN now.
+
+	* cp-parse.y (overloaddef): Warn that using `overload' is an

+
+	These four are from Niklas Hallqvist:
+

+
+	* cp-call.c (build_method_call): Don't look for constructors
+	called by initialization inside class methods in the classes'
+	bases (as opposed to inherited methods).
+
+	* cp-typeck.c (convert_for_initialization): In the case of
+	templates, make sure build_method_call knows which instantiation

+
+	* cp-decl.c (grokdeclarator): Instead of an assert, return a
+	NULL_TREE if the return_type's not return_ctor.

+
+	* cp-decl.c: Include sys/types.h for systems that need things for
+	signal.h.
+
+	Wed Dec  2 15:51:34 1992  Mike Stump  (mrs@cygnus.com)
+
+	* cp-call.c (build_method_call): Don't call abort for pure virtual
+	methods, instead, call the user-defined method.  Addresses of pure
+	virtual methods are probably still wrong.
+
+	Wed Dec  2 14:44:41 1992  Brendan Kehoe  (brendan@lisa.cygnus.com)
+
+	* cp-call.c (convert_harshness): If parm's null for a reference (as

+
+	Tue Dec  1 18:05:20 1992  Brendan Kehoe  (brendan@lisa.cygnus.com)
+
+	* cp-decl.c (grokdeclarator): Make member initialization be a

+	constant members being initialized if `-ansi' is being used.
+	(finish_decl): Only complain about uninitialized const's that aren't
+	members when acting -pedantic, since we'll have already issued the
+	error about initializing a field.

+	* cp-type2.c (build_functional_cast): Revert change of Nov 2,
+	concerning clearing the TREE_VALUE of a default parameter.
+
+	Tue Dec  1 11:09:50 1992  Brendan Kehoe  (brendan@lisa.cygnus.com)
+
+	* cp-call.c (build_method_call): When looking for a default arg
+	initialized by a ctor, be careful of a null ref w/ operand 1.
+
+	* cp-method.c (icat): Handle an argument of `1' first, since it's
+	the most common case.

+
+	Thu Nov 26 11:22:12 1992  Mike Stump  (mrs@cygnus.com)
+
+	* c++: Put a newline after for arg and before do, as ``for arg do''
+	is not accepted by all shells.
+
+	Mon Nov 23 13:21:43 1992  Brendan Kehoe  (brendan@cygnus.com)
+
+	* c++ (-lm): Also recognize -lmath as a math library.
+
+	* c++ (first): Only shift if $first is no, on the chance we got no
+	arguments at all.  If we didn't get anything, say so (since -lg++
+	will fake out the gcc driver into thinking we want to do something).
+
+	* cp-parse.y (paren_expr_or_null): New rule to emit an error when an
+	empty condition is used when it shouldn't.
+	(simple_if, stmt): Use it for `if', `while', and `do'.
+
+	* cp-decl.c (start_decl): If grokdeclarator returns a
+	void_type_node, return a NULL_TREE.
+
+	* cp-typeck.c (build_modify_expr_1): When calling build_opfncall for
+	`operator=', use make_node to create a plain NOP_EXPR for it to use,
+	rather than trying to pass NOP_EXPR down hoping it gets there intact.
+	(build_modify_expr): Ditto.
+	* cp-method.c (build_opfncall): Use TREE_CODE on ARG3 for a
+	MODIFY_EXPR, since it'll be coming in properly as a tree now.
+
+	Sat Nov 21 02:33:28 1992  Brendan Kehoe  (brendan@cygnus.com)
+
+	* cp-init.c (expand_default_init): Clear DECL_REGISTER if we're

+	type if the IDENTIFIER_TYPE_VALUE isn't there.
+
+	* cp-method.c (build_overload_nested_name): Use DECL_NAME instead of

+	pass in that the prologue/epilogue has loaded the stack size into
+	$8 if large stack frame.  Completely rewrite large stack frame
+	support, so that it doesn't abort if large stack frame, saved GP

+Tue Oct 12 13:28:18 1993  Per Bothner  (bothner@kalessin.cygnus.com)
+
+	* fixproto:  Re-write.  We now assume that there are two
+	source directories (source_dir_all and source_dir_std).  These
+	are handled differently.  All files in source_dir_all (normally
+	./include) are processed, but in source_dir_std (normally
+	/usr/include) we only process the standard ANSI/Posix ones where
+	we might be able to add missing prototypes.
+	* scan-decls.c (scan_decls):  Rewrote from being a program whose
+	output is piped to patch-header, to a subroutine called by
+	patch-header.  This should be somewhat more efficient.
+	* Makefile.in (scan-decls):  Removed rule to make program.
+	* patch-header.c (recognized_macro, recognized_extern,
+	recognized_function):  New functins, with logic moved out from
+	read_scan_file, so they can be called by scan_decls.
+	* patch-header (main):  Read the original header file into a
+	buffer (rather than reading it with stdio).  This should be more
+	efficient, partly because we can re-write it in place.
+	(inf_skip_spaces, inf_read_upto, inf_scan_ident):  New functions,
+	based on skip_spaces, read_upto, and scan_ident in scan.c, but
+	these read from the in-memory buffer mentioned above.
+	* scan-types.sh:  Don't check for sigset_t, since it can be a
+	struct, whose name cannot be simplify replaced by its definition.
+	* Makefile.in (deduced.h):  Don't pass -nostdinc.

+	  compiler is setting up the `this' pointer.
+	* cp-cvt.c (convert_pointer_to): Just call convert_pointer_to_real
+	  to implement functionality.
+	* cp-cvt.c (convert_pointer_to_real): New routine.  Uses new

+
+	* Makefile.in (CPLUS_OBJS): Add error.o and cp-error.o

+
+	* cp-decl.c (poplevel): Only call remember_end_note if we haven't
+	already created the block.  Set TREE_USED on the block.

+	Remove the error check of such typedefs hiding other fields in the
+	same scope.  Remove the pushdecl_class_level call since start_decl
+	does the work now.
+
+	Class scoping (and type value caching) redone.  The new behaviour
+	is triggered by NEW_CLASS_SCOPING being defined to 1.  The old
+	behavior is accomplished by defining it to the value 0.  The entries
+	below describes the effective changes when NEW_CLASS_SCOPING is set
+	to non-zero.
+
+	* cp-class.c (set_class_shadows): Add prototype.
+	(previous_class_values): New variable.

+	TYPE_DECL.

+	setting of IDENTIFIER_CLASS_VALUE.
+	(adjust_type_value): Removed.

+	(pushdecl_class_level): Call push_class_level_binding.  Set the
+	type value if we're seeing a TYPE_DECL.
+	(push_class_level_binding): New function whose guts came from
+	pushdecl_class_level.
+	(globalize_nested_type): See to that both the class_shadowed and
+	type_shadowed lists in the binding stack gets updated correctly.
+	Don't call set_identifier_type_value on the DECL_NESTED_TYPENAME.
+	Clear DECL_CLASS_CONTEXT as well as DECL_CONTEXT.  Install a
+	correct IDENTIFIER_{CLASS,TYPE}_VALUE if needed.
+	(grokdeclarator): Prefer pushdecl_class_level over pushtag when
+	recording a nested typedef.
+	(build_enumerator): Don't install a method-local enumerator into
+	class scope.
+	* cp-decl2.c (grokfield): Don't call set_identifier_type_value.
+	* cp-search.c (closed_envelopes): New list containing information
+	of what decls should be pushed when entering a class scope.
+	(dfs_pushdecls): Build and maintain the closed_envelopes list
+	instead of managing the IDENTIFIER_CLASS_VALUEs directly.
+	(dfs_compress_decls): Adapted to recognize the envelopes
+	dfs_pushdecls has installed in the IDENTIFIER_CLASS_VALUE slots.
+	(push_class_decls): Tell overload_template_name to push the
+	template decls into class scope instead of building a new level.
+	Added code to open up the envelopes in closed_envelopes and
+	install the class/type values in the class binding contour with
+	proper shadowing.
+	(dfs_popdecls): Removed.
+	(pop_class_decls): Removed the actual decl-popping code, leaving
+	just the obstack freeing pop_search_level call.  The popping is
+	automatically handled by poplevel now.
+	* cp-tree.h (NEW_CLASS_SCOPING): A new macro constant defaulted to
+	the value 1.
+	(adjust_type_value): Prototype removed.
+	(push_class_level_binding): Added prototype.

+	on compilers that can't deal with a return inside it.  Change all
+	uses of them to do `return FOO_RETURN'.

+	based on the stack pointer, account for the stack pointer changing
+	due to the intermediate pushes generated.

+
+Installing GNU CC
+*****************
+
+   Here is the procedure for installing GNU CC on a Unix system.  See
+*Note VMS Install::, for VMS systems.  In this section we assume you
+compile in the same directory that contains the source files; see *Note
+Other Dir::, to find out how to compile in a separate directory on Unix
+systems.
+
+   You cannot install GNU C by itself on MSDOS; it will not compile
+under any MSDOS compiler except itself.  You need to get the complete
+compilation package DJGPP, which includes binaries as well as sources,
+and includes all the necessary compilation tools and libraries.
+
+  1. If you have built GNU CC previously in the same directory for a
+     different target machine, do `make distclean' to delete all files
+     that might be invalid.  One of the files this deletes is
+     `Makefile'; if `make distclean' complains that `Makefile' does not
+     exist, it probably means that the directory is already suitably
+     clean.
+
+  2. On a System V release 4 system, make sure `/usr/bin' precedes
+     `/usr/ucb' in `PATH'.  The `cc' command in `/usr/ucb' uses
+     libraries which have bugs.
+
+  3. Specify the host, build and target machine configurations.  You do
+     this by running the file `configure'.
+
+     The "build" machine is the system which you are using, the "host"
+     machine is the system where you want to run the resulting compiler
+     (normally the build machine), and the "target" machine is the
+     system for which you want the compiler to generate code.
+
+     If you are building a compiler to produce code for the machine it
+     runs on (a native compiler), you normally do not need to specify
+     any operands to `configure'; it will try to guess the type of
+     machine you are on and use that as the build, host and target
+     machines.  So you don't need to specify a configuration when
+     building a native compiler unless `configure' cannot figure out
+     what your configuration is or guesses wrong.
+
+     In those cases, specify the build machine's "configuration name"
+     with the `--build' option; the host and target will default to be
+     the same as the build machine.  (If you are building a
+     cross-compiler, see *Note Cross-Compiler::.)
+
+     Here is an example:
+
+          ./configure --build=sparc-sun-sunos4.1
+
+     A configuration name may be canonical or it may be more or less
+     abbreviated.
+
+     A canonical configuration name has three parts, separated by
+     dashes.  It looks like this: `CPU-COMPANY-SYSTEM'.  (The three
+     parts may themselves contain dashes; `configure' can figure out
+     which dashes serve which purpose.)  For example,
+     `m68k-sun-sunos4.1' specifies a Sun 3.
+
+     You can also replace parts of the configuration by nicknames or
+     aliases.  For example, `sun3' stands for `m68k-sun', so
+     `sun3-sunos4.1' is another way to specify a Sun 3.  You can also
+     use simply `sun3-sunos', since the version of SunOS is assumed by
+     default to be version 4.  `sun3-bsd' also works, since `configure'
+     knows that the only BSD variant on a Sun 3 is SunOS.
+
+     You can specify a version number after any of the system types,
+     and some of the CPU types.  In most cases, the version is
+     irrelevant, and will be ignored.  So you might as well specify the
+     version if you know it.
+
+     See *Note Configurations::, for a list of supported configuration
+     names and notes on many of the configurations.  You should check
+     the notes in that section before proceeding any further with the
+     installation of GNU CC.
+
+     There are four additional options you can specify independently to
+     describe variant hardware and software configurations.  These are
+     `--with-gnu-as', `--with-gnu-ld', `--with-stabs' and `--nfp'.
+
+    `--with-gnu-as'
+          If you will use GNU CC with the GNU assembler (GAS), you
+          should declare this by using the `--with-gnu-as' option when
+          you run `configure'.
+
+          Using this option does not install GAS.  It only modifies the
+          output of GNU CC to work with GAS.  Building and installing
+          GAS is up to you.
+
+          Conversely, if you *do not* wish to use GAS and do not specify
+          `--with-gnu-as' when building GNU CC, it is up to you to make
+          sure that GAS is not installed.  GNU CC searches for a
+          program named `as' in various directories; if the program it
+          finds is GAS, then it runs GAS.  If you are not sure where
+          GNU CC finds the assembler it is using, try specifying `-v'
+          when you run it.
+
+          The systems where it makes a difference whether you use GAS
+          are
+          `hppa1.0-ANY-ANY', `hppa1.1-ANY-ANY', `i386-ANY-sysv',
+          `i386-ANY-isc',
+          `i860-ANY-bsd', `m68k-bull-sysv', `m68k-hp-hpux',
+          `m68k-sony-bsd',
+          `m68k-altos-sysv', `m68000-hp-hpux', `m68000-att-sysv',
+          `ANY-lynx-lynxos', and `mips-ANY').  On any other system,
+          `--with-gnu-as' has no effect.
+
+          On the systems listed above (except for the HP-PA, for ISC on
+          the 386, and for `mips-sgi-irix5.*'), if you use GAS, you
+          should also use the GNU linker (and specify `--with-gnu-ld').
+
+    `--with-gnu-ld'
+          Specify the option `--with-gnu-ld' if you plan to use the GNU
+          linker with GNU CC.
+
+          This option does not cause the GNU linker to be installed; it
+          just modifies the behavior of GNU CC to work with the GNU
+          linker.  Specifically, it inhibits the installation of
+          `collect2', a program which otherwise serves as a front-end
+          for the system's linker on most configurations.
+
+    `--with-stabs'
+          On MIPS based systems and on Alphas, you must specify whether
+          you want GNU CC to create the normal ECOFF debugging format,
+          or to use BSD-style stabs passed through the ECOFF symbol
+          table.  The normal ECOFF debug format cannot fully handle
+          languages other than C.  BSD stabs format can handle other
+          languages, but it only works with the GNU debugger GDB.
+
+          Normally, GNU CC uses the ECOFF debugging format by default;
+          if you prefer BSD stabs, specify `--with-stabs' when you
+          configure GNU CC.
+
+          No matter which default you choose when you configure GNU CC,
+          the user can use the `-gcoff' and `-gstabs+' options to
+          specify explicitly the debug format for a particular
+          compilation.
+
+          `--with-stabs' is meaningful on the ISC system on the 386,
+          also, if `--with-gas' is used.  It selects use of stabs
+          debugging information embedded in COFF output.  This kind of
+          debugging information supports C++ well; ordinary COFF
+          debugging information does not.
+
+          `--with-stabs' is also meaningful on 386 systems running
+          SVR4.  It selects use of stabs debugging information embedded
+          in ELF output.  The C++ compiler currently (2.6.0) does not
+          support the DWARF debugging information normally used on 386
+          SVR4 platforms; stabs provide a workable alternative.  This
+          requires gas and gdb, as the normal SVR4 tools can not
+          generate or interpret stabs.
+
+    `--nfp'
+          On certain systems, you must specify whether the machine has
+          a floating point unit.  These systems include
+          `m68k-sun-sunosN' and `m68k-isi-bsd'.  On any other system,
+          `--nfp' currently has no effect, though perhaps there are
+          other systems where it could usefully make a difference.
+
+     The `configure' script searches subdirectories of the source
+     directory for other compilers that are to be integrated into GNU
+     CC.  The GNU compiler for C++, called G++ is in a subdirectory
+     named `cp'.  `configure' inserts rules into `Makefile' to build
+     all of those compilers.
+
+     Here we spell out what files will be set up by `configure'.
+     Normally you need not be concerned with these files.
+
+        * A file named `config.h' is created that contains a `#include'
+          of the top-level config file for the machine you will run the
+          compiler on (*note The Configuration File:
+          (gcc.info)Config.).  This file is responsible for defining
+          information about the host machine.  It includes `tm.h'.
+
+          The top-level config file is located in the subdirectory
+          `config'.  Its name is always `xm-SOMETHING.h'; usually
+          `xm-MACHINE.h', but there are some exceptions.
+
+          If your system does not support symbolic links, you might
+          want to set up `config.h' to contain a `#include' command
+          which refers to the appropriate file.
+
+        * A file named `tconfig.h' is created which includes the
+          top-level config file for your target machine.  This is used
+          for compiling certain programs to run on that machine.
+
+        * A file named `tm.h' is created which includes the
+          machine-description macro file for your target machine.  It
+          should be in the subdirectory `config' and its name is often
+          `MACHINE.h'.
+
+        * The command file `configure' also constructs the file
+          `Makefile' by adding some text to the template file
+          `Makefile.in'.  The additional text comes from files in the
+          `config' directory, named `t-TARGET' and `x-HOST'.  If these
+          files do not exist, it means nothing needs to be added for a
+          given target or host.
+
+  4. The standard directory for installing GNU CC is `/usr/local/lib'.
+     If you want to install its files somewhere else, specify
+     `--prefix=DIR' when you run `configure'.  Here DIR is a directory
+     name to use instead of `/usr/local' for all purposes with one
+     exception: the directory `/usr/local/include' is searched for
+     header files no matter where you install the compiler.  To override
+     this name, use the `--local-prefix' option below.
+
+  5. Specify `--local-prefix=DIR' if you want the compiler to search
+     directory `DIR/include' for locally installed header files
+     *instead* of `/usr/local/include'.
+
+     You should specify `--local-prefix' *only* if your site has a
+     different convention (not `/usr/local') for where to put
+     site-specific files.
+
+     *Do not* specify `/usr' as the `--local-prefix'!  The directory
+     you use for `--local-prefix' *must not* contain any of the
+     system's standard header files.  If it did contain them, certain
+     programs would be miscompiled (including GNU Emacs, on certain
+     targets), because this would override and nullify the header file
+     corrections made by the `fixincludes' script.
+
+  6. Make sure the Bison parser generator is installed.  (This is
+     unnecessary if the Bison output files `c-parse.c' and `cexp.c' are
+     more recent than `c-parse.y' and `cexp.y' and you do not plan to
+     change the `.y' files.)
+
+     Bison versions older than Sept 8, 1988 will produce incorrect
+     output for `c-parse.c'.
+
+  7. If you have chosen a configuration for GNU CC which requires other
+     GNU tools (such as GAS or the GNU linker) instead of the standard
+     system tools, install the required tools in the build directory
+     under the names `as', `ld' or whatever is appropriate.  This will
+     enable the compiler to find the proper tools for compilation of
+     the program `enquire'.
+
+     Alternatively, you can do subsequent compilation using a value of
+     the `PATH' environment variable such that the necessary GNU tools
+     come before the standard system tools.
+
+  8. Build the compiler.  Just type `make LANGUAGES=c' in the compiler
+     directory.
+
+     `LANGUAGES=c' specifies that only the C compiler should be
+     compiled.  The makefile normally builds compilers for all the
+     supported languages; currently, C, C++ and Objective C.  However,
+     C is the only language that is sure to work when you build with
+     other non-GNU C compilers.  In addition, building anything but C
+     at this stage is a waste of time.
+
+     In general, you can specify the languages to build by typing the
+     argument `LANGUAGES="LIST"', where LIST is one or more words from
+     the list `c', `c++', and `objective-c'.  If you have any
+     additional GNU compilers as subdirectories of the GNU CC source
+     directory, you may also specify their names in this list.
+
+     Ignore any warnings you may see about "statement not reached" in
+     `insn-emit.c'; they are normal.  Also, warnings about "unknown
+     escape sequence" are normal in `genopinit.c' and perhaps some
+     other files.  Likewise, you should ignore warnings about "constant
+     is so large that it is unsigned" in `insn-emit.c' and
+     `insn-recog.c' and a warning about a comparison always being zero
+     in `enquire.o'.  Any other compilation errors may represent bugs in
+     the port to your machine or operating system, and should be
+     investigated and reported.
+
+     Some commercial compilers fail to compile GNU CC because they have
+     bugs or limitations.  For example, the Microsoft compiler is said
+     to run out of macro space.  Some Ultrix compilers run out of
+     expression space; then you need to break up the statement where
+     the problem happens.
+
+  9. If you are building a cross-compiler, stop here.  *Note
+     Cross-Compiler::.
+
+ 10. Move the first-stage object files and executables into a
+     subdirectory with this command:
+
+          make stage1
+
+     The files are moved into a subdirectory named `stage1'.  Once
+     installation is complete, you may wish to delete these files with
+     `rm -r stage1'.
+
+ 11. If you have chosen a configuration for GNU CC which requires other
+     GNU tools (such as GAS or the GNU linker) instead of the standard
+     system tools, install the required tools in the `stage1'
+     subdirectory under the names `as', `ld' or whatever is
+     appropriate.  This will enable the stage 1 compiler to find the
+     proper tools in the following stage.
+
+     Alternatively, you can do subsequent compilation using a value of
+     the `PATH' environment variable such that the necessary GNU tools
+     come before the standard system tools.
+
+ 12. Recompile the compiler with itself, with this command:
+
+          make CC="stage1/xgcc -Bstage1/" CFLAGS="-g -O2"
+
+     This is called making the stage 2 compiler.
+
+     The command shown above builds compilers for all the supported
+     languages.  If you don't want them all, you can specify the
+     languages to build by typing the argument `LANGUAGES="LIST"'.  LIST
+     should contain one or more words from the list `c', `c++',
+     `objective-c', and `proto'.  Separate the words with spaces.
+     `proto' stands for the programs `protoize' and `unprotoize'; they
+     are not a separate language, but you use `LANGUAGES' to enable or
+     disable their installation.
+
+     If you are going to build the stage 3 compiler, then you might
+     want to build only the C language in stage 2.
+
+     Once you have built the stage 2 compiler, if you are short of disk
+     space, you can delete the subdirectory `stage1'.
+
+     On a 68000 or 68020 system lacking floating point hardware, unless
+     you have selected a `tm.h' file that expects by default that there
+     is no such hardware, do this instead:
+
+          make CC="stage1/xgcc -Bstage1/" CFLAGS="-g -O2 -msoft-float"
+
+ 13. If you wish to test the compiler by compiling it with itself one
+     more time, install any other necessary GNU tools (such as GAS or
+     the GNU linker) in the `stage2' subdirectory as you did in the
+     `stage1' subdirectory, then do this:
+
+          make stage2
+          make CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O2"
+
+     This is called making the stage 3 compiler.  Aside from the `-B'
+     option, the compiler options should be the same as when you made
+     the stage 2 compiler.  But the `LANGUAGES' option need not be the
+     same.  The command shown above builds compilers for all the
+     supported languages; if you don't want them all, you can specify
+     the languages to build by typing the argument `LANGUAGES="LIST"',
+     as described above.
+
+     If you do not have to install any additional GNU tools, you may
+     use the command
+
+          make bootstrap LANGUAGES=LANGUAGE-LIST BOOT_CFLAGS=OPTION-LIST
+
+     instead of making `stage1', `stage2', and performing the two
+     compiler builds.
+
+ 14. Then compare the latest object files with the stage 2 object
+     files--they ought to be identical, aside from time stamps (if any).
+
+     On some systems, meaningful comparison of object files is
+     impossible; they always appear "different."  This is currently
+     true on Solaris and some systems that use ELF object file format.
+     On some versions of Irix on SGI machines and DEC Unix (OSF/1) on
+     Alpha systems, you will not be able to compare the files without
+     specifying `-save-temps'; see the description of individual
+     systems above to see if you get comparison failures.  You may have
+     similar problems on other systems.
+
+     Use this command to compare the files:
+
+          make compare
+
+     This will mention any object files that differ between stage 2 and
+     stage 3.  Any difference, no matter how innocuous, indicates that
+     the stage 2 compiler has compiled GNU CC incorrectly, and is
+     therefore a potentially serious bug which you should investigate
+     and report.
+
+     If your system does not put time stamps in the object files, then
+     this is a faster way to compare them (using the Bourne shell):
+
+          for file in *.o; do
+          cmp $file stage2/$file
+          done
+
+     If you have built the compiler with the `-mno-mips-tfile' option on
+     MIPS machines, you will not be able to compare the files.
+
+ 15. Install the compiler driver, the compiler's passes and run-time
+     support with `make install'.  Use the same value for `CC',
+     `CFLAGS' and `LANGUAGES' that you used when compiling the files
+     that are being installed.  One reason this is necessary is that
+     some versions of Make have bugs and recompile files gratuitously
+     when you do this step.  If you use the same variable values, those
+     files will be recompiled properly.
+
+     For example, if you have built the stage 2 compiler, you can use
+     the following command:
+
+          make install CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O" LANGUAGES="LIST"
+
+     This copies the files `cc1', `cpp' and `libgcc.a' to files `cc1',
+     `cpp' and `libgcc.a' in the directory
+     `/usr/local/lib/gcc-lib/TARGET/VERSION', which is where the
+     compiler driver program looks for them.  Here TARGET is the target
+     machine type specified when you ran `configure', and VERSION is
+     the version number of GNU CC.  This naming scheme permits various
+     versions and/or cross-compilers to coexist.
+
+     This also copies the driver program `xgcc' into
+     `/usr/local/bin/gcc', so that it appears in typical execution
+     search paths.
+
+     On some systems, this command causes recompilation of some files.
+     This is usually due to bugs in `make'.  You should either ignore
+     this problem, or use GNU Make.
+
+     *Warning: there is a bug in `alloca' in the Sun library.  To avoid
+     this bug, be sure to install the executables of GNU CC that were
+     compiled by GNU CC.  (That is, the executables from stage 2 or 3,
+     not stage 1.)  They use `alloca' as a built-in function and never
+     the one in the library.*
+
+     (It is usually better to install GNU CC executables from stage 2
+     or 3, since they usually run faster than the ones compiled with
+     some other compiler.)
+
+ 16. If you're going to use C++, it's likely that you need to also
+     install the libg++ distribution.  It should be available from the
+     same place where you got the GNU C distribution.  Just as GNU C
+     does not distribute a C runtime library, it also does not include
+     a C++ run-time library.  All I/O functionality, special class
+     libraries, etc., are available in the libg++ distribution.
+
+Configurations Supported by GNU CC
+==================================
+
+   Here are the possible CPU types:
+
+     1750a, a29k, alpha, arm, cN, clipper, dsp16xx, elxsi, h8300,
+     hppa1.0, hppa1.1, i370, i386, i486, i586, i860, i960, m68000, m68k,
+     m88k, mips, mipsel, mips64, mips64el, ns32k, powerpc, powerpcle,
+     pyramid, romp, rs6000, sh, sparc, sparclite, sparc64, vax, we32k.
+
+   Here are the recognized company names.  As you can see, customary
+abbreviations are used rather than the longer official names.
+
+     acorn, alliant, altos, apollo, att, bull, cbm, convergent, convex,
+     crds, dec, dg, dolphin, elxsi, encore, harris, hitachi, hp, ibm,
+     intergraph, isi, mips, motorola, ncr, next, ns, omron, plexus,
+     sequent, sgi, sony, sun, tti, unicom, wrs.
+
+   The company name is meaningful only to disambiguate when the rest of
+the information supplied is insufficient.  You can omit it, writing
+just `CPU-SYSTEM', if it is not needed.  For example, `vax-ultrix4.2'
+is equivalent to `vax-dec-ultrix4.2'.
+
+   Here is a list of system types:
+
+     386bsd, aix, acis, amigados, aos, aout, bosx, bsd, clix, coff,
+     ctix, cxux, dgux, dynix, ebmon, ecoff, elf, esix, freebsd, hms,
+     genix, gnu, gnu/linux, hiux, hpux, iris, irix, isc, luna, lynxos,
+     mach, minix, msdos, mvs, netbsd, newsos, nindy, ns, osf, osfrose,
+     ptx, riscix, riscos, rtu, sco, sim, solaris, sunos, sym, sysv,
+     udi, ultrix, unicos, uniplus, unos, vms, vsta, vxworks, winnt,
+     xenix.
+
+You can omit the system type; then `configure' guesses the operating
+system from the CPU and company.
+
+   You can add a version number to the system type; this may or may not
+make a difference.  For example, you can write `bsd4.3' or `bsd4.4' to
+distinguish versions of BSD.  In practice, the version number is most
+needed for `sysv3' and `sysv4', which are often treated differently.
+
+   If you specify an impossible combination such as `i860-dg-vms', then
+you may get an error message from `configure', or it may ignore part of
+the information and do the best it can with the rest.  `configure'
+always prints the canonical name for the alternative that it used.  GNU
+CC does not support all possible alternatives.
+
+   Often a particular model of machine has a name.  Many machine names
+are recognized as aliases for CPU/company combinations.  Thus, the
+machine name `sun3', mentioned above, is an alias for `m68k-sun'.
+Sometimes we accept a company name as a machine name, when the name is
+popularly used for a particular machine.  Here is a table of the known
+machine names:
+
+     3300, 3b1, 3bN, 7300, altos3068, altos, apollo68, att-7300,
+     balance, convex-cN, crds, decstation-3100, decstation, delta,
+     encore, fx2800, gmicro, hp7NN, hp8NN, hp9k2NN, hp9k3NN, hp9k7NN,
+     hp9k8NN, iris4d, iris, isi68, m3230, magnum, merlin, miniframe,
+     mmax, news-3600, news800, news, next, pbd, pc532, pmax, powerpc,
+     powerpcle, ps2, risc-news, rtpc, sun2, sun386i, sun386, sun3,
+     sun4, symmetry, tower-32, tower.
+
+Remember that a machine name specifies both the cpu type and the company
+name.  If you want to install your own homemade configuration files,
+you can use `local' as the company name to access them.  If you use
+configuration `CPU-local', the configuration name without the cpu prefix
+is used to form the configuration file names.
+
+   Thus, if you specify `m68k-local', configuration uses files
+`m68k.md', `local.h', `m68k.c', `xm-local.h', `t-local', and `x-local',
+all in the directory `config/m68k'.
+
+   Here is a list of configurations that have special treatment or
+special things you must know:
+
+`1750a-*-*'
+     MIL-STD-1750A processors.
+
+     Starting with GCC 2.6.1, the MIL-STD-1750A cross configuration no
+     longer supports the Tektronix Assembler, but instead produces
+     output for `as1750', an assembler/linker available under the GNU
+     Public License for the 1750A. Contact *kellogg@space.otn.dasa.de*
+     for more details on obtaining `as1750'.  A similarly licensed
+     simulator for the 1750A is available from same address.
+
+     You should ignore a fatal error during the building of libgcc
+     (libgcc is not yet implemented for the 1750A.)
+
+     The `as1750' assembler requires the file `ms1750.inc', which is
+     found in the directory `config/1750a'.
+
+     GNU CC produced the same sections as the Fairchild F9450 C
+     Compiler, namely:
+
+    `Normal'
+          The program code section.
+
+    `Static'
+          The read/write (RAM) data section.
+
+    `Konst'
+          The read-only (ROM) constants section.
+
+    `Init'
+          Initialization section (code to copy KREL to SREL).
+
+     The smallest addressable unit is 16 bits (BITS_PER_UNIT is 16).
+     This means that type `char' is represented with a 16-bit word per
+     character.  The 1750A's "Load/Store Upper/Lower Byte" instructions
+     are not used by GNU CC.
+
+`alpha-*-osf1'
+     Systems using processors that implement the DEC Alpha architecture
+     and are running the DEC Unix (OSF/1) operating system, for example
+     the DEC Alpha AXP systems.  (VMS on the Alpha is not currently
+     supported by GNU CC.)
+
+     GNU CC writes a `.verstamp' directive to the assembler output file
+     unless it is built as a cross-compiler.  It gets the version to
+     use from the system header file `/usr/include/stamp.h'.  If you
+     install a new version of DEC Unix, you should rebuild GCC to pick
+     up the new version stamp.
+
+     Note that since the Alpha is a 64-bit architecture,
+     cross-compilers from 32-bit machines will not generate code as
+     efficient as that generated when the compiler is running on a
+     64-bit machine because many optimizations that depend on being
+     able to represent a word on the target in an integral value on the
+     host cannot be performed.  Building cross-compilers on the Alpha
+     for 32-bit machines has only been tested in a few cases and may
+     not work properly.
+
+     `make compare' may fail on old versions of DEC Unix unless you add
+     `-save-temps' to `CFLAGS'.  On these systems, the name of the
+     assembler input file is stored in the object file, and that makes
+     comparison fail if it differs between the `stage1' and `stage2'
+     compilations.  The option `-save-temps' forces a fixed name to be
+     used for the assembler input file, instead of a randomly chosen
+     name in `/tmp'.  Do not add `-save-temps' unless the comparisons
+     fail without that option.  If you add `-save-temps', you will have
+     to manually delete the `.i' and `.s' files after each series of
+     compilations.
+
+     GNU CC now supports both the native (ECOFF) debugging format used
+     by DBX and GDB and an encapsulated STABS format for use only with
+     GDB.  See the discussion of the `--with-stabs' option of
+     `configure' above for more information on these formats and how to
+     select them.
+
+     There is a bug in DEC's assembler that produces incorrect line
+     numbers for ECOFF format when the `.align' directive is used.  To
+     work around this problem, GNU CC will not emit such alignment
+     directives while writing ECOFF format debugging information even
+     if optimization is being performed.  Unfortunately, this has the
+     very undesirable side-effect that code addresses when `-O' is
+     specified are different depending on whether or not `-g' is also
+     specified.
+
+     To avoid this behavior, specify `-gstabs+' and use GDB instead of
+     DBX.  DEC is now aware of this problem with the assembler and
+     hopes to provide a fix shortly.
+
+`arm'
+     Advanced RISC Machines ARM-family processors.  These are often
+     used in embedded applications.  There are no standard Unix
+     configurations.  This configuration corresponds to the basic
+     instruction sequences and will produce a.out format object modules.
+
+     You may need to make a variant of the file `arm.h' for your
+     particular configuration.
+
+`arm-*-riscix'
+     The ARM2 or ARM3 processor running RISC iX, Acorn's port of BSD
+     Unix.  If you are running a version of RISC iX prior to 1.2 then
+     you must specify the version number during configuration.  Note
+     that the assembler shipped with RISC iX does not support stabs
+     debugging information; a new version of the assembler, with stabs
+     support included, is now available from Acorn.
+
+`a29k'
+     AMD Am29k-family processors.  These are normally used in embedded
+     applications.  There are no standard Unix configurations.  This
+     configuration corresponds to AMD's standard calling sequence and
+     binary interface and is compatible with other 29k tools.
+
+     You may need to make a variant of the file `a29k.h' for your
+     particular configuration.
+
+`a29k-*-bsd'
+     AMD Am29050 used in a system running a variant of BSD Unix.
+
+`decstation-*'
+     DECstations can support three different personalities: Ultrix, DEC
+     OSF/1, and OSF/rose.  To configure GCC for these platforms use the
+     following configurations:
+
+    `decstation-ultrix'
+          Ultrix configuration.
+
+    `decstation-osf1'
+          Dec's version of OSF/1.
+
+    `decstation-osfrose'
+          Open Software Foundation reference port of OSF/1 which uses
+          the OSF/rose object file format instead of ECOFF.  Normally,
+          you would not select this configuration.
+
+     The MIPS C compiler needs to be told to increase its table size
+     for switch statements with the `-Wf,-XNg1500' option in order to
+     compile `cp/parse.c'.  If you use the `-O2' optimization option,
+     you also need to use `-Olimit 3000'.  Both of these options are
+     automatically generated in the `Makefile' that the shell script
+     `configure' builds.  If you override the `CC' make variable and
+     use the MIPS compilers, you may need to add `-Wf,-XNg1500 -Olimit
+     3000'.
+
+`elxsi-elxsi-bsd'
+     The Elxsi's C compiler has known limitations that prevent it from
+     compiling GNU C.  Please contact `mrs@cygnus.com' for more details.
+
+`dsp16xx'
+     A port to the AT&T DSP1610 family of processors.
+
+`h8300-*-*'
+     The calling convention and structure layout has changed in release
+     2.6.  All code must be recompiled.  The calling convention now
+     passes the first three arguments in function calls in registers.
+     Structures are no longer a multiple of 2 bytes.
+
+`hppa*-*-*'
+     There are two variants of this CPU, called 1.0 and 1.1, which have
+     different machine descriptions.  You must use the right one for
+     your machine.  All 7NN machines and 8N7 machines use 1.1, while
+     all other 8NN machines use 1.0.
+
+     The easiest way to handle this problem is to use `configure hpNNN'
+     or `configure hpNNN-hpux', where NNN is the model number of the
+     machine.  Then `configure' will figure out if the machine is a 1.0
+     or 1.1.  Use `uname -a' to find out the model number of your
+     machine.
+
+     `-g' does not work on HP-UX, since that system uses a peculiar
+     debugging format which GNU CC does not know about.  However, `-g'
+     will work if you also use GAS and GDB in conjunction with GCC.  We
+     highly recommend using GAS for all HP-PA configurations.
+
+     You should be using GAS-2.3 (or later) along with GDB-4.12 (or
+     later).  These can be retrieved from all the traditional GNU ftp
+     archive sites.
+
+     Build GAS and install the resulting binary as:
+
+          /usr/local/lib/gcc-lib/CONFIGURATION/GCCVERSION/as
+
+     where CONFIGURATION is the configuration name (perhaps
+     `hpNNN-hpux') and GCCVERSION is the GNU CC version number.  Do
+     this *before* starting the build process, otherwise you will get
+     errors from the HPUX assembler while building `libgcc2.a'.  The
+     command
+
+          make install-dir
+
+     will create the necessary directory hierarchy so you can install
+     GAS before building GCC.
+
+     To enable debugging, configure GNU CC with the `--with-gnu-as'
+     option before building.
+
+     It has been reported that GNU CC produces invalid assembly code for
+     1.1 machines running HP-UX 8.02 when using the HP assembler.
+     Typically the errors look like this:
+          as: bug.s @line#15 [err#1060]
+            Argument 0 or 2 in FARG upper
+                   - lookahead = ARGW1=FR,RTNVAL=GR
+          as: foo.s @line#28 [err#1060]
+            Argument 0 or 2 in FARG upper
+                   - lookahead = ARGW1=FR
+
+     You can check the version of HP-UX you are running by executing
+     the command `uname -r'.   If you are indeed running HP-UX 8.02 on
+     a PA and using the HP assembler then configure GCC with
+     "hpNNN-hpux8.02".
+
+`i370-*-*'
+     This port is very preliminary and has many known bugs.  We hope to
+     have a higher-quality port for this machine soon.
+
+`i386-*-linuxoldld'
+     Use this configuration to generate a.out binaries on Linux if you
+     do not have gas/binutils version 2.5.2 or later installed. This is
+     an obsolete configuration.
+
+`i386-*-linuxaout'
+     Use this configuration to generate a.out binaries on Linux. This
+     configuration is being superseded. You must use gas/binutils
+     version 2.5.2 or later.
+
+`i386-*-linux'
+     Use this configuration to generate ELF binaries on Linux.  You must
+     use gas/binutils version 2.5.2 or later.
+
+`i386-*-sco'
+     Compilation with RCC is recommended.  Also, it may be a good idea
+     to link with GNU malloc instead of the malloc that comes with the
+     system.
+
+`i386-*-sco3.2v4'
+     Use this configuration for SCO release 3.2 version 4.
+
+`i386-*-isc'
+     It may be a good idea to link with GNU malloc instead of the
+     malloc that comes with the system.
+
+     In ISC version 4.1, `sed' core dumps when building `deduced.h'.
+     Use the version of `sed' from version 4.0.
+
+`i386-*-esix'
+     It may be good idea to link with GNU malloc instead of the malloc
+     that comes with the system.
+
+`i386-ibm-aix'
+     You need to use GAS version 2.1 or later, and and LD from GNU
+     binutils version 2.2 or later.
+
+`i386-sequent-bsd'
+     Go to the Berkeley universe before compiling.  In addition, you
+     probably need to create a file named `string.h' containing just
+     one line: `#include <strings.h>'.
+
+`i386-sequent-ptx1*'
+     Sequent DYNIX/ptx 1.x.
+
+`i386-sequent-ptx2*'
+     Sequent DYNIX/ptx 2.x.
+
+`i386-sun-sunos4'
+     You may find that you need another version of GNU CC to begin
+     bootstrapping with, since the current version when built with the
+     system's own compiler seems to get an infinite loop compiling part
+     of `libgcc2.c'.  GNU CC version 2 compiled with GNU CC (any
+     version) seems not to have this problem.
+
+     See *Note Sun Install::, for information on installing GNU CC on
+     Sun systems.
+
+`i[345]86-*-winnt3.5'
+     This version requires a GAS that has not let been released.  Until
+     it is, you can get a prebuilt binary version via anonymous ftp from
+     `cs.washington.edu:pub/gnat' or `cs.nyu.edu:pub/gnat'. You must
+     also use the Microsoft header files from the Windows NT 3.5 SDK.
+     Find these on the CDROM in the `/mstools/h' directory dated
+     9/4/94.  You must use a fixed version of Microsoft linker made
+     especially for NT 3.5, which is also is available on the NT 3.5
+     SDK CDROM.  If you do not have this linker, can you also use the
+     linker from Visual C/C++ 1.0 or 2.0.
+
+     Installing GNU CC for NT builds a wrapper linker, called `ld.exe',
+     which mimics the behaviour of Unix `ld' in the specification of
+     libraries (`-L' and `-l').  `ld.exe' looks for both Unix and
+     Microsoft named libraries.  For example, if you specify `-lfoo',
+     `ld.exe' will look first for `libfoo.a' and then for `foo.lib'.
+
+     You may install GNU CC for Windows NT in one of two ways,
+     depending on whether or not you have a Unix-like shell and various
+     Unix-like utilities.
+
+       1. If you do not have a Unix-like shell and few Unix-like
+          utilities, you will use a DOS style batch script called
+          `configure.bat'.  Invoke it as `configure winnt' from an
+          MSDOS console window or from the program manager dialog box.
+          `configure.bat' assumes you have already installed and have
+          in your path a Unix-like `sed' program which is used to
+          create a working `Makefile' from `Makefile.in'.
+
+          `Makefile' uses the Microsoft Nmake program maintenance
+          utility and the Visual C/C++ V8.00 compiler to build GNU CC.
+          You need only have the utilities `sed' and `touch' to use
+          this installation method, which only automatically builds the
+          compiler itself.  You must then examine what `fixinc.winnt'
+          does, edit the header files by hand and build `libgcc.a'
+          manually.
+
+       2. The second type of installation assumes you are running a
+          Unix-like shell, have a complete suite of Unix-like utilities
+          in your path, and have a previous version of GNU CC already
+          installed, either through building it via the above
+          installation method or acquiring a pre-built binary.  In this
+          case, use the `configure' script in the normal fashion.
+
+`i860-intel-osf1'
+     This is the Paragon.  If you have version 1.0 of the operating
+     system, you need to take special steps to build GNU CC due to
+     peculiarities of the system.  Newer system versions have no
+     problem.  See the section `Installation Problems' in the GNU CC
+     Manual.
+
+`*-lynx-lynxos'
+     LynxOS 2.2 and earlier comes with GNU CC 1.x already installed as
+     `/bin/gcc'.  You should compile with this instead of `/bin/cc'.
+     You can tell GNU CC to use the GNU assembler and linker, by
+     specifying `--with-gnu-as --with-gnu-ld' when configuring.  These
+     will produce COFF format object files and executables;  otherwise
+     GNU CC will use the installed tools, which produce a.out format
+     executables.
+
+`m68000-hp-bsd'
+     HP 9000 series 200 running BSD.  Note that the C compiler that
+     comes with this system cannot compile GNU CC; contact
+     `law@cs.utah.edu' to get binaries of GNU CC for bootstrapping.
+
+`m68k-altos'
+     Altos 3068.  You must use the GNU assembler, linker and debugger.
+     Also, you must fix a kernel bug.  Details in the file
+     `README.ALTOS'.
+
+`m68k-att-sysv'
+     AT&T 3b1, a.k.a. 7300 PC.  Special procedures are needed to
+     compile GNU CC with this machine's standard C compiler, due to
+     bugs in that compiler.  You can bootstrap it more easily with
+     previous versions of GNU CC if you have them.
+
+     Installing GNU CC on the 3b1 is difficult if you do not already
+     have GNU CC running, due to bugs in the installed C compiler.
+     However, the following procedure might work.  We are unable to
+     test it.
+
+       1. Comment out the `#include "config.h"' line on line 37 of
+          `cccp.c' and do `make cpp'.  This makes a preliminary version
+          of GNU cpp.
+
+       2. Save the old `/lib/cpp' and copy the preliminary GNU cpp to
+          that file name.
+
+       3. Undo your change in `cccp.c', or reinstall the original
+          version, and do `make cpp' again.
+
+       4. Copy this final version of GNU cpp into `/lib/cpp'.
+
+       5. Replace every occurrence of `obstack_free' in the file
+          `tree.c' with `_obstack_free'.
+
+       6. Run `make' to get the first-stage GNU CC.
+
+       7. Reinstall the original version of `/lib/cpp'.
+
+       8. Now you can compile GNU CC with itself and install it in the
+          normal fashion.
+
+`m68k-bull-sysv'
+     Bull DPX/2 series 200 and 300 with BOS-2.00.45 up to BOS-2.01. GNU
+     CC works either with native assembler or GNU assembler. You can use
+     GNU assembler with native coff generation by providing
+     `--with-gnu-as' to the configure script or use GNU assembler with
+     dbx-in-coff encapsulation by providing `--with-gnu-as --stabs'.
+     For any problem with native assembler or for availability of the
+     DPX/2 port of GAS, contact `F.Pierresteguy@frcl.bull.fr'.
+
+`m68k-crds-unox'
+     Use `configure unos' for building on Unos.
+
+     The Unos assembler is named `casm' instead of `as'.  For some
+     strange reason linking `/bin/as' to `/bin/casm' changes the
+     behavior, and does not work.  So, when installing GNU CC, you
+     should install the following script as `as' in the subdirectory
+     where the passes of GCC are installed:
+
+          #!/bin/sh
+          casm $*
+
+     The default Unos library is named `libunos.a' instead of `libc.a'.
+     To allow GNU CC to function, either change all references to
+     `-lc' in `gcc.c' to `-lunos' or link `/lib/libc.a' to
+     `/lib/libunos.a'.
+
+     When compiling GNU CC with the standard compiler, to overcome bugs
+     in the support of `alloca', do not use `-O' when making stage 2.
+     Then use the stage 2 compiler with `-O' to make the stage 3
+     compiler.  This compiler will have the same characteristics as the
+     usual stage 2 compiler on other systems.  Use it to make a stage 4
+     compiler and compare that with stage 3 to verify proper
+     compilation.
+
+     (Perhaps simply defining `ALLOCA' in `x-crds' as described in the
+     comments there will make the above paragraph superfluous.  Please
+     inform us of whether this works.)
+
+     Unos uses memory segmentation instead of demand paging, so you
+     will need a lot of memory.  5 Mb is barely enough if no other
+     tasks are running.  If linking `cc1' fails, try putting the object
+     files into a library and linking from that library.
+
+`m68k-hp-hpux'
+     HP 9000 series 300 or 400 running HP-UX.  HP-UX version 8.0 has a
+     bug in the assembler that prevents compilation of GNU CC.  To fix
+     it, get patch PHCO_4484 from HP.
+
+     In addition, if you wish to use gas `--with-gnu-as' you must use
+     gas version 2.1 or later, and you must use the GNU linker version
+     2.1 or later.  Earlier versions of gas relied upon a program which
+     converted the gas output into the native HP/UX format, but that
+     program has not been kept up to date.  gdb does not understand
+     that native HP/UX format, so you must use gas if you wish to use
+     gdb.
+
+`m68k-sun'
+     Sun 3.  We do not provide a configuration file to use the Sun FPA
+     by default, because programs that establish signal handlers for
+     floating point traps inherently cannot work with the FPA.
+
+     See *Note Sun Install::, for information on installing GNU CC on
+     Sun systems.
+
+`m88k-*-svr3'
+     Motorola m88k running the AT&T/Unisoft/Motorola V.3 reference port.
+     These systems tend to use the Green Hills C, revision 1.8.5, as the
+     standard C compiler.  There are apparently bugs in this compiler
+     that result in object files differences between stage 2 and stage
+     3.  If this happens, make the stage 4 compiler and compare it to
+     the stage 3 compiler.  If the stage 3 and stage 4 object files are
+     identical, this suggests you encountered a problem with the
+     standard C compiler; the stage 3 and 4 compilers may be usable.
+
+     It is best, however, to use an older version of GNU CC for
+     bootstrapping if you have one.
+
+`m88k-*-dgux'
+     Motorola m88k running DG/UX.  To build 88open BCS native or cross
+     compilers on DG/UX, specify the configuration name as
+     `m88k-*-dguxbcs' and build in the 88open BCS software development
+     environment.  To build ELF native or cross compilers on DG/UX,
+     specify `m88k-*-dgux' and build in the DG/UX ELF development
+     environment.  You set the software development environment by
+     issuing `sde-target' command and specifying either `m88kbcs' or
+     `m88kdguxelf' as the operand.
+
+     If you do not specify a configuration name, `configure' guesses the
+     configuration based on the current software development
+     environment.
+
+`m88k-tektronix-sysv3'
+     Tektronix XD88 running UTekV 3.2e.  Do not turn on optimization
+     while building stage1 if you bootstrap with the buggy Green Hills
+     compiler.  Also, The bundled LAI System V NFS is buggy so if you
+     build in an NFS mounted directory, start from a fresh reboot, or
+     avoid NFS all together.  Otherwise you may have trouble getting
+     clean comparisons between stages.
+
+`mips-mips-bsd'
+     MIPS machines running the MIPS operating system in BSD mode.  It's
+     possible that some old versions of the system lack the functions
+     `memcpy', `memcmp', and `memset'.  If your system lacks these, you
+     must remove or undo the definition of `TARGET_MEM_FUNCTIONS' in
+     `mips-bsd.h'.
+
+     The MIPS C compiler needs to be told to increase its table size
+     for switch statements with the `-Wf,-XNg1500' option in order to
+     compile `cp/parse.c'.  If you use the `-O2' optimization option,
+     you also need to use `-Olimit 3000'.  Both of these options are
+     automatically generated in the `Makefile' that the shell script
+     `configure' builds.  If you override the `CC' make variable and
+     use the MIPS compilers, you may need to add `-Wf,-XNg1500 -Olimit
+     3000'.
+
+`mips-mips-riscos*'
+     The MIPS C compiler needs to be told to increase its table size
+     for switch statements with the `-Wf,-XNg1500' option in order to
+     compile `cp/parse.c'.  If you use the `-O2' optimization option,
+     you also need to use `-Olimit 3000'.  Both of these options are
+     automatically generated in the `Makefile' that the shell script
+     `configure' builds.  If you override the `CC' make variable and
+     use the MIPS compilers, you may need to add `-Wf,-XNg1500 -Olimit
+     3000'.
+
+     MIPS computers running RISC-OS can support four different
+     personalities: default, BSD 4.3, System V.3, and System V.4 (older
+     versions of RISC-OS don't support V.4).  To configure GCC for
+     these platforms use the following configurations:
+
+    `mips-mips-riscos`rev''
+          Default configuration for RISC-OS, revision `rev'.
+
+    `mips-mips-riscos`rev'bsd'
+          BSD 4.3 configuration for RISC-OS, revision `rev'.
+
+    `mips-mips-riscos`rev'sysv4'
+          System V.4 configuration for RISC-OS, revision `rev'.
+
+    `mips-mips-riscos`rev'sysv'
+          System V.3 configuration for RISC-OS, revision `rev'.
+
+     The revision `rev' mentioned above is the revision of RISC-OS to
+     use.  You must reconfigure GCC when going from a RISC-OS revision
+     4 to RISC-OS revision 5.  This has the effect of avoiding a linker
+     bug.
+
+`mips-sgi-*'
+     In order to compile GCC on an SGI running IRIX 4, the "c.hdr.lib"
+     option must be installed from the CD-ROM supplied from Silicon
+     Graphics.  This is found on the 2nd CD in release 4.0.1.
+
+     In order to compile GCC on an SGI running IRIX 5, the
+     "compiler_dev.hdr" subsystem must be installed from the IDO CD-ROM
+     supplied by Silicon Graphics.
+
+     `make compare' may fail on version 5 of IRIX unless you add
+     `-save-temps' to `CFLAGS'.  On these systems, the name of the
+     assembler input file is stored in the object file, and that makes
+     comparison fail if it differs between the `stage1' and `stage2'
+     compilations.  The option `-save-temps' forces a fixed name to be
+     used for the assembler input file, instead of a randomly chosen
+     name in `/tmp'.  Do not add `-save-temps' unless the comparisons
+     fail without that option.  If you do you `-save-temps', you will
+     have to manually delete the `.i' and `.s' files after each series
+     of compilations.
+
+     The MIPS C compiler needs to be told to increase its table size
+     for switch statements with the `-Wf,-XNg1500' option in order to
+     compile `cp/parse.c'.  If you use the `-O2' optimization option,
+     you also need to use `-Olimit 3000'.  Both of these options are
+     automatically generated in the `Makefile' that the shell script
+     `configure' builds.  If you override the `CC' make variable and
+     use the MIPS compilers, you may need to add `-Wf,-XNg1500 -Olimit
+     3000'.
+
+     On Irix version 4.0.5F, and perhaps on some other versions as well,
+     there is an assembler bug that reorders instructions incorrectly.
+     To work around it, specify the target configuration
+     `mips-sgi-irix4loser'.  This configuration inhibits assembler
+     optimization.
+
+     In a compiler configured with target `mips-sgi-irix4', you can turn
+     off assembler optimization by using the `-noasmopt' option.  This
+     compiler option passes the option `-O0' to the assembler, to
+     inhibit reordering.
+
+     The `-noasmopt' option can be useful for testing whether a problem
+     is due to erroneous assembler reordering.  Even if a problem does
+     not go away with `-noasmopt', it may still be due to assembler
+     reordering--perhaps GNU CC itself was miscompiled as a result.
+
+     To enable debugging under Irix 5, you must use GNU as 2.5 or later,
+     and use the `--with-gnu-as' configure option when configuring gcc.
+     GNU as is distributed as part of the binutils package.

+     (which uses ELF instead of COFF).  Support for 5.0.2 will probably
+     be provided soon by volunteers.  In particular, the linker does
+     not like the code generated by GCC when shared libraries are

+     Encore ns32000 system.  Encore systems are supported only under
+     BSD.
+
+`ns32k-*-genix'
+     National Semiconductor ns32000 system.  Genix has bugs in `alloca'
+     and `malloc'; you must get the compiled versions of these from GNU
+     Emacs.
+
+`ns32k-sequent'
+     Go to the Berkeley universe before compiling.  In addition, you
+     probably need to create a file named `string.h' containing just
+     one line: `#include <strings.h>'.
+
+`ns32k-utek'

+
+`romp-*-aos'
+`romp-*-mach'
+     The only operating systems supported for the IBM RT PC are AOS and
+     MACH.  GNU CC does not support AIX running on the RT.  We
+     recommend you compile GNU CC with an earlier version of itself; if
+     you compile GNU CC with `hc', the Metaware compiler, it will work,
+     but you will get mismatches between the stage 2 and stage 3
+     compilers in various files.  These errors are minor differences in
+     some floating-point constants and can be safely ignored; the stage
+     3 compiler is correct.
+
+`rs6000-*-aix'
+`powerpc-*-aix'
+     Various early versions of each release of the IBM XLC compiler
+     will not bootstrap GNU CC.  Symptoms include differences between
+     the stage2 and stage3 object files, and errors when compiling
+     `libgcc.a' or `enquire'.  Known problematic releases include:
+     xlc-1.2.1.8, xlc-1.3.0.0 (distributed with AIX 3.2.5), and
+     xlc-1.3.0.19.  Both xlc-1.2.1.28 and xlc-1.3.0.24 (PTF 432238) are
+     known to produce working versions of GNU CC, but most other recent
+     releases correctly bootstrap GNU CC.  Also, releases of AIX prior
+     to AIX 3.2.4 include a version of the IBM assembler which does not
+     accept debugging directives: assembler updates are available as
+     PTFs.  Also, if you are using AIX 3.2.5 or greater and the GNU
+     assembler, you must have a version modified after October 16th,
+     1995 in order for the GNU C compiler to build.  See the file
+     `README.RS6000' for more details on of these problems.
+
+     GNU CC does not yet support the 64-bit PowerPC instructions.
+
+     Objective C does not work on this architecture because it makes
+     assumptions that are incompatible with the calling conventions.
+
+     AIX on the RS/6000 provides support (NLS) for environments outside
+     of the United States.  Compilers and assemblers use NLS to support
+     locale-specific representations of various objects including
+     floating-point numbers ("." vs "," for separating decimal
+     fractions).  There have been problems reported where the library
+     linked with GNU CC does not produce the same floating-point
+     formats that the assembler accepts.  If you have this problem, set
+     the LANG environment variable to "C" or "En_US".
+
+     Due to changes in the way that GNU CC invokes the binder (linker)
+     for AIX 4.1, you may now receive warnings of duplicate symbols
+     from the link step that were not reported before.  The assembly
+     files generated by GNU CC for AIX have always included multiple
+     symbol definitions for certain global variable and function
+     declarations in the original program.  The warnings should not
+     prevent the linker from producing a correct library or runnable
+     executable.

+     Meanwhile, compiling `cp/parse.c' with pcc does not work because of
+     an internal table size limitation in that compiler.  To avoid this
+     problem, compile just the GNU C compiler first, and use it to
+     recompile building all the languages that you want to run.

+
+     Don't use `-g' when compiling with the system's compiler.  The
+     system's linker seems to be unable to handle such a large program
+     with debugging information.
+
+     The system's compiler runs out of capacity when compiling `stmt.c'
+     in GNU CC.  You can work around this by building `cpp' in GNU CC
+     first, then use that instead of the system's preprocessor with the
+     system's C compiler to compile `stmt.c'.  Here is how:
+
+          mv /lib/cpp /lib/cpp.att
+          cp cpp /lib/cpp.gnu
+          echo '/lib/cpp.gnu -traditional ${1+"$@"}' > /lib/cpp
+          chmod +x /lib/cpp
+
+     The system's compiler produces bad code for some of the GNU CC
+     optimization files.  So you must build the stage 2 compiler without
+     optimization.  Then build a stage 3 compiler with optimization.
+     That executable should work.  Here are the necessary commands:
+
+          make LANGUAGES=c CC=stage1/xgcc CFLAGS="-Bstage1/ -g"
+          make stage2
+          make CC=stage2/xgcc CFLAGS="-Bstage2/ -g -O"
+
+     You may need to raise the ULIMIT setting to build a C++ compiler,
+     as the file `cc1plus' is larger than one megabyte.
+
+Compilation in a Separate Directory
+===================================
+
+   If you wish to build the object files and executables in a directory
+other than the one containing the source files, here is what you must
+do differently:
+
+  1. Make sure you have a version of Make that supports the `VPATH'
+     feature.  (GNU Make supports it, as do Make versions on most BSD
+     systems.)
+
+  2. If you have ever run `configure' in the source directory, you must
+     undo the configuration.  Do this by running:
+
+          make distclean
+
+  3. Go to the directory in which you want to build the compiler before
+     running `configure':
+
+          mkdir gcc-sun3
+          cd gcc-sun3
+
+     On systems that do not support symbolic links, this directory must
+     be on the same file system as the source code directory.
+
+  4. Specify where to find `configure' when you run it:
+
+          ../gcc/configure ...
+
+     This also tells `configure' where to find the compiler sources;
+     `configure' takes the directory from the file name that was used to
+     invoke it.  But if you want to be sure, you can specify the source
+     directory with the `--srcdir' option, like this:
+
+          ../gcc/configure --srcdir=../gcc OTHER OPTIONS
+
+     The directory you specify with `--srcdir' need not be the same as
+     the one that `configure' is found in.
+
+   Now, you can run `make' in that directory.  You need not repeat the
+configuration steps shown above, when ordinary source files change.  You
+must, however, run `configure' again when the configuration files
+change, if your system does not support symbolic links.
+
+Building and Installing a Cross-Compiler
+========================================
+
+   GNU CC can function as a cross-compiler for many machines, but not
+all.
+
+   * Cross-compilers for the Mips as target using the Mips assembler
+     currently do not work, because the auxiliary programs
+     `mips-tdump.c' and `mips-tfile.c' can't be compiled on anything
+     but a Mips.  It does work to cross compile for a Mips if you use
+     the GNU assembler and linker.
+
+   * Cross-compilers between machines with different floating point
+     formats have not all been made to work.  GNU CC now has a floating
+     point emulator with which these can work, but each target machine
+     description needs to be updated to take advantage of it.
+
+   * Cross-compilation between machines of different word sizes is
+     somewhat problematic and sometimes does not work.
+
+   Since GNU CC generates assembler code, you probably need a
+cross-assembler that GNU CC can run, in order to produce object files.
+If you want to link on other than the target machine, you need a
+cross-linker as well.  You also need header files and libraries suitable
+for the target machine that you can install on the host machine.
+
+Steps of Cross-Compilation
+--------------------------
+
+   To compile and run a program using a cross-compiler involves several
+steps:
+
+   * Run the cross-compiler on the host machine to produce assembler
+     files for the target machine.  This requires header files for the
+     target machine.
+
+   * Assemble the files produced by the cross-compiler.  You can do this
+     either with an assembler on the target machine, or with a
+     cross-assembler on the host machine.
+
+   * Link those files to make an executable.  You can do this either
+     with a linker on the target machine, or with a cross-linker on the
+     host machine.  Whichever machine you use, you need libraries and
+     certain startup files (typically `crt....o') for the target
+     machine.
+
+   It is most convenient to do all of these steps on the same host
+machine, since then you can do it all with a single invocation of GNU
+CC.  This requires a suitable cross-assembler and cross-linker.  For
+some targets, the GNU assembler and linker are available.
+
+Configuring a Cross-Compiler
+----------------------------
+
+   To build GNU CC as a cross-compiler, you start out by running
+`configure'.  Use the `--target=TARGET' to specify the target type.  If
+`configure' was unable to correctly identify the system you are running
+on, also specify the `--build=BUILD' option.  For example, here is how
+to configure for a cross-compiler that produces code for an HP 68030
+system running BSD on a system that `configure' can correctly identify:
+
+     ./configure --target=m68k-hp-bsd4.3
+
+Tools and Libraries for a Cross-Compiler
+----------------------------------------
+
+   If you have a cross-assembler and cross-linker available, you should
+install them now.  Put them in the directory `/usr/local/TARGET/bin'.
+Here is a table of the tools you should put in this directory:
+
+`as'
+     This should be the cross-assembler.
+
+`ld'
+     This should be the cross-linker.
+
+`ar'
+     This should be the cross-archiver: a program which can manipulate
+     archive files (linker libraries) in the target machine's format.
+
+`ranlib'
+     This should be a program to construct a symbol table in an archive
+     file.
+
+   The installation of GNU CC will find these programs in that
+directory, and copy or link them to the proper place to for the
+cross-compiler to find them when run later.
+
+   The easiest way to provide these files is to build the Binutils
+package and GAS.  Configure them with the same `--host' and `--target'
+options that you use for configuring GNU CC, then build and install
+them.  They install their executables automatically into the proper
+directory.  Alas, they do not support all the targets that GNU CC
+supports.
+
+   If you want to install libraries to use with the cross-compiler,
+such as a standard C library, put them in the directory
+`/usr/local/TARGET/lib'; installation of GNU CC copies all all the
+files in that subdirectory into the proper place for GNU CC to find
+them and link with them.  Here's an example of copying some libraries
+from a target machine:
+
+     ftp TARGET-MACHINE
+     lcd /usr/local/TARGET/lib
+     cd /lib
+     get libc.a
+     cd /usr/lib
+     get libg.a
+     get libm.a
+     quit
+
+The precise set of libraries you'll need, and their locations on the
+target machine, vary depending on its operating system.
+
+   Many targets require "start files" such as `crt0.o' and `crtn.o'
+which are linked into each executable; these too should be placed in
+`/usr/local/TARGET/lib'.  There may be several alternatives for
+`crt0.o', for use with profiling or other compilation options.  Check
+your target's definition of `STARTFILE_SPEC' to find out what start
+files it uses.  Here's an example of copying these files from a target
+machine:
+
+     ftp TARGET-MACHINE
+     lcd /usr/local/TARGET/lib
+     prompt
+     cd /lib
+     mget *crt*.o
+     cd /usr/lib
+     mget *crt*.o
+     quit
+
+`libgcc.a' and Cross-Compilers
+------------------------------
+
+   Code compiled by GNU CC uses certain runtime support functions
+implicitly.  Some of these functions can be compiled successfully with
+GNU CC itself, but a few cannot be.  These problem functions are in the
+source file `libgcc1.c'; the library made from them is called
+`libgcc1.a'.
+
+   When you build a native compiler, these functions are compiled with
+some other compiler-the one that you use for bootstrapping GNU CC.
+Presumably it knows how to open code these operations, or else knows how
+to call the run-time emulation facilities that the machine comes with.
+But this approach doesn't work for building a cross-compiler.  The
+compiler that you use for building knows about the host system, not the
+target system.
+
+   So, when you build a cross-compiler you have to supply a suitable
+library `libgcc1.a' that does the job it is expected to do.
+
+   To compile `libgcc1.c' with the cross-compiler itself does not work.
+The functions in this file are supposed to implement arithmetic
+operations that GNU CC does not know how to open code for your target
+machine.  If these functions are compiled with GNU CC itself, they will
+compile into infinite recursion.
+
+   On any given target, most of these functions are not needed.  If GNU
+CC can open code an arithmetic operation, it will not call these
+functions to perform the operation.  It is possible that on your target
+machine, none of these functions is needed.  If so, you can supply an
+empty library as `libgcc1.a'.
+
+   Many targets need library support only for multiplication and
+division.  If you are linking with a library that contains functions for
+multiplication and division, you can tell GNU CC to call them directly
+by defining the macros `MULSI3_LIBCALL', and the like.  These macros
+need to be defined in the target description macro file.  For some
+targets, they are defined already.  This may be sufficient to avoid the
+need for libgcc1.a; if so, you can supply an empty library.
+
+   Some targets do not have floating point instructions; they need other
+functions in `libgcc1.a', which do floating arithmetic.  Recent
+versions of GNU CC have a file which emulates floating point.  With a
+certain amount of work, you should be able to construct a floating
+point emulator that can be used as `libgcc1.a'.  Perhaps future
+versions will contain code to do this automatically and conveniently.
+That depends on whether someone wants to implement it.
+
+   Some embedded targets come with all the necessary `libgcc1.a'
+routines written in C or assembler.  These targets build `libgcc1.a'
+automatically and you do not need to do anything special for them.
+Other embedded targets do not need any `libgcc1.a' routines since all
+the necessary operations are supported by the hardware.
+
+   If your target system has another C compiler, you can configure GNU
+CC as a native compiler on that machine, build just `libgcc1.a' with
+`make libgcc1.a' on that machine, and use the resulting file with the
+cross-compiler.  To do this, execute the following on the target
+machine:
+
+     cd TARGET-BUILD-DIR
+     ./configure --host=sparc --target=sun3
+     make libgcc1.a
+
+And then this on the host machine:
+
+     ftp TARGET-MACHINE
+     binary
+     cd TARGET-BUILD-DIR
+     get libgcc1.a
+     quit
+
+   Another way to provide the functions you need in `libgcc1.a' is to
+define the appropriate `perform_...' macros for those functions.  If
+these definitions do not use the C arithmetic operators that they are
+meant to implement, you should be able to compile them with the
+cross-compiler you are building.  (If these definitions already exist
+for your target file, then you are all set.)
+
+   To build `libgcc1.a' using the perform macros, use
+`LIBGCC1=libgcc1.a OLDCC=./xgcc' when building the compiler.
+Otherwise, you should place your replacement library under the name
+`libgcc1.a' in the directory in which you will build the
+cross-compiler, before you run `make'.
+
+Cross-Compilers and Header Files
+--------------------------------
+
+   If you are cross-compiling a standalone program or a program for an
+embedded system, then you may not need any header files except the few
+that are part of GNU CC (and those of your program).  However, if you
+intend to link your program with a standard C library such as `libc.a',
+then you probably need to compile with the header files that go with
+the library you use.
+
+   The GNU C compiler does not come with these files, because (1) they
+are system-specific, and (2) they belong in a C library, not in a
+compiler.
+
+   If the GNU C library supports your target machine, then you can get
+the header files from there (assuming you actually use the GNU library
+when you link your program).
+
+   If your target machine comes with a C compiler, it probably comes
+with suitable header files also.  If you make these files accessible
+from the host machine, the cross-compiler can use them also.
+
+   Otherwise, you're on your own in finding header files to use when
+cross-compiling.
+
+   When you have found suitable header files, put them in
+`/usr/local/TARGET/include', before building the cross compiler.  Then
+installation will run fixincludes properly and install the corrected
+versions of the header files where the compiler will use them.
+
+   Provide the header files before you build the cross-compiler, because
+the build stage actually runs the cross-compiler to produce parts of
+`libgcc.a'.  (These are the parts that *can* be compiled with GNU CC.)
+Some of them need suitable header files.
+
+   Here's an example showing how to copy the header files from a target
+machine.  On the target machine, do this:
+
+     (cd /usr/include; tar cf - .) > tarfile
+
+   Then, on the host machine, do this:
+
+     ftp TARGET-MACHINE
+     lcd /usr/local/TARGET/include
+     get tarfile
+     quit
+     tar xf tarfile
+
+Actually Building the Cross-Compiler
+------------------------------------
+
+   Now you can proceed just as for compiling a single-machine compiler
+through the step of building stage 1.  If you have not provided some
+sort of `libgcc1.a', then compilation will give up at the point where
+it needs that file, printing a suitable error message.  If you do
+provide `libgcc1.a', then building the compiler will automatically
+compile and link a test program called `libgcc1-test'; if you get
+errors in the linking, it means that not all of the necessary routines
+in `libgcc1.a' are available.
+
+   You must provide the header file `float.h'.  One way to do this is
+to compile `enquire' and run it on your target machine.  The job of
+`enquire' is to run on the target machine and figure out by experiment
+the nature of its floating point representation.  `enquire' records its
+findings in the header file `float.h'.  If you can't produce this file
+by running `enquire' on the target machine, then you will need to come
+up with a suitable `float.h' in some other way (or else, avoid using it
+in your programs).
+
+   Do not try to build stage 2 for a cross-compiler.  It doesn't work to
+rebuild GNU CC as a cross-compiler using the cross-compiler, because
+that would produce a program that runs on the target machine, not on the
+host.  For example, if you compile a 386-to-68030 cross-compiler with
+itself, the result will not be right either for the 386 (because it was
+compiled into 68030 code) or for the 68030 (because it was configured
+for a 386 as the host).  If you want to compile GNU CC into 68030 code,
+whether you compile it on a 68030 or with a cross-compiler on a 386, you
+must specify a 68030 as the host when you configure it.
+
+   To install the cross-compiler, use `make install', as usual.
+
+Installing GNU CC on the Sun
+============================
+
+   On Solaris (version 2.1), do not use the linker or other tools in
+`/usr/ucb' to build GNU CC.  Use `/usr/ccs/bin'.
+
+   Make sure the environment variable `FLOAT_OPTION' is not set when
+you compile `libgcc.a'.  If this option were set to `f68881' when
+`libgcc.a' is compiled, the resulting code would demand to be linked
+with a special startup file and would not link properly without special
+pains.
+
+   There is a bug in `alloca' in certain versions of the Sun library.
+To avoid this bug, install the binaries of GNU CC that were compiled by
+GNU CC.  They use `alloca' as a built-in function and never the one in
+the library.
+
+   Some versions of the Sun compiler crash when compiling GNU CC.  The
+problem is a segmentation fault in cpp.  This problem seems to be due to
+the bulk of data in the environment variables.  You may be able to avoid
+it by using the following command to compile GNU CC with Sun CC:
+
+     make CC="TERMCAP=x OBJS=x LIBFUNCS=x STAGESTUFF=x cc"
+
+Installing GNU CC on VMS
+========================
+
+   The VMS version of GNU CC is distributed in a backup saveset
+containing both source code and precompiled binaries.
+
+   To install the `gcc' command so you can use the compiler easily, in
+the same manner as you use the VMS C compiler, you must install the VMS
+CLD file for GNU CC as follows:
+
+  1. Define the VMS logical names `GNU_CC' and `GNU_CC_INCLUDE' to
+     point to the directories where the GNU CC executables
+     (`gcc-cpp.exe', `gcc-cc1.exe', etc.) and the C include files are
+     kept respectively.  This should be done with the commands:
+
+          $ assign /system /translation=concealed -
+            disk:[gcc.] gnu_cc
+          $ assign /system /translation=concealed -
+            disk:[gcc.include.] gnu_cc_include
+
+     with the appropriate disk and directory names.  These commands can
+     be placed in your system startup file so they will be executed
+     whenever the machine is rebooted.  You may, if you choose, do this
+     via the `GCC_INSTALL.COM' script in the `[GCC]' directory.
+
+  2. Install the `GCC' command with the command line:
+
+          $ set command /table=sys$common:[syslib]dcltables -
+            /output=sys$common:[syslib]dcltables gnu_cc:[000000]gcc
+          $ install replace sys$common:[syslib]dcltables
+
+  3. To install the help file, do the following:
+
+          $ library/help sys$library:helplib.hlb gcc.hlp
+
+     Now you can invoke the compiler with a command like `gcc /verbose
+     file.c', which is equivalent to the command `gcc -v -c file.c' in
+     Unix.
+
+   If you wish to use GNU C++ you must first install GNU CC, and then
+perform the following steps:
+
+  1. Define the VMS logical name `GNU_GXX_INCLUDE' to point to the
+     directory where the preprocessor will search for the C++ header
+     files.  This can be done with the command:
+
+          $ assign /system /translation=concealed -
+            disk:[gcc.gxx_include.] gnu_gxx_include
+
+     with the appropriate disk and directory name.  If you are going to
+     be using libg++, this is where the libg++ install procedure will
+     install the libg++ header files.
+
+  2. Obtain the file `gcc-cc1plus.exe', and place this in the same
+     directory that `gcc-cc1.exe' is kept.
+
+     The GNU C++ compiler can be invoked with a command like `gcc /plus
+     /verbose file.cc', which is equivalent to the command `g++ -v -c
+     file.cc' in Unix.
+
+   We try to put corresponding binaries and sources on the VMS
+distribution tape.  But sometimes the binaries will be from an older
+version than the sources, because we don't always have time to update
+them.  (Use the `/version' option to determine the version number of
+the binaries and compare it with the source file `version.c' to tell
+whether this is so.)  In this case, you should use the binaries you get
+to recompile the sources.  If you must recompile, here is how:
+
+  1. Execute the command procedure `vmsconfig.com' to set up the files
+     `tm.h', `config.h', `aux-output.c', and `md.', and to create files
+     `tconfig.h' and `hconfig.h'.  This procedure also creates several
+     linker option files used by `make-cc1.com' and a data file used by
+     `make-l2.com'.
+
+          $ @vmsconfig.com
+
+  2. Setup the logical names and command tables as defined above.  In
+     addition, define the VMS logical name `GNU_BISON' to point at the
+     to the directories where the Bison executable is kept.  This
+     should be done with the command:
+
+          $ assign /system /translation=concealed -
+            disk:[bison.] gnu_bison
+
+     You may, if you choose, use the `INSTALL_BISON.COM' script in the
+     `[BISON]' directory.
+
+  3. Install the `BISON' command with the command line:
+
+          $ set command /table=sys$common:[syslib]dcltables -
+            /output=sys$common:[syslib]dcltables -
+            gnu_bison:[000000]bison
+          $ install replace sys$common:[syslib]dcltables
+
+  4. Type `@make-gcc' to recompile everything (alternatively, submit
+     the file `make-gcc.com' to a batch queue).  If you wish to build
+     the GNU C++ compiler as well as the GNU CC compiler, you must
+     first edit `make-gcc.com' and follow the instructions that appear
+     in the comments.
+
+  5. In order to use GCC, you need a library of functions which GCC
+     compiled code will call to perform certain tasks, and these
+     functions are defined in the file `libgcc2.c'.  To compile this
+     you should use the command procedure `make-l2.com', which will
+     generate the library `libgcc2.olb'.  `libgcc2.olb' should be built
+     using the compiler built from the same distribution that
+     `libgcc2.c' came from, and `make-gcc.com' will automatically do
+     all of this for you.
+
+     To install the library, use the following commands:
+
+          $ library gnu_cc:[000000]gcclib/delete=(new,eprintf)
+          $ library gnu_cc:[000000]gcclib/delete=L_*
+          $ library libgcc2/extract=*/output=libgcc2.obj
+          $ library gnu_cc:[000000]gcclib libgcc2.obj
+
+     The first command simply removes old modules that will be replaced
+     with modules from `libgcc2' under different module names.  The
+     modules `new' and `eprintf' may not actually be present in your
+     `gcclib.olb'--if the VMS librarian complains about those modules
+     not being present, simply ignore the message and continue on with
+     the next command.  The second command removes the modules that
+     came from the previous version of the library `libgcc2.c'.
+
+     Whenever you update the compiler on your system, you should also
+     update the library with the above procedure.
+
+  6. You may wish to build GCC in such a way that no files are written
+     to the directory where the source files reside.  An example would
+     be the when the source files are on a read-only disk.  In these
+     cases, execute the following DCL commands (substituting your
+     actual path names):
+
+          $ assign dua0:[gcc.build_dir.]/translation=concealed, -
+                   dua1:[gcc.source_dir.]/translation=concealed  gcc_build
+          $ set default gcc_build:[000000]
+
+     where the directory `dua1:[gcc.source_dir]' contains the source
+     code, and the directory `dua0:[gcc.build_dir]' is meant to contain
+     all of the generated object files and executables.  Once you have
+     done this, you can proceed building GCC as described above.  (Keep
+     in mind that `gcc_build' is a rooted logical name, and thus the
+     device names in each element of the search list must be an actual
+     physical device name rather than another rooted logical name).
+
+  7. *If you are building GNU CC with a previous version of GNU CC, you
+     also should check to see that you have the newest version of the
+     assembler*.  In particular, GNU CC version 2 treats global constant
+     variables slightly differently from GNU CC version 1, and GAS
+     version 1.38.1 does not have the patches required to work with GCC
+     version 2.  If you use GAS 1.38.1, then `extern const' variables
+     will not have the read-only bit set, and the linker will generate
+     warning messages about mismatched psect attributes for these
+     variables.  These warning messages are merely a nuisance, and can
+     safely be ignored.
+
+     If you are compiling with a version of GNU CC older than 1.33,
+     specify `/DEFINE=("inline=")' as an option in all the
+     compilations.  This requires editing all the `gcc' commands in
+     `make-cc1.com'.  (The older versions had problems supporting
+     `inline'.)  Once you have a working 1.33 or newer GNU CC, you can
+     change this file back.
+
+  8. If you want to build GNU CC with the VAX C compiler, you will need
+     to make minor changes in `make-cccp.com' and `make-cc1.com' to
+     choose alternate definitions of `CC', `CFLAGS', and `LIBS'.  See
+     comments in those files.  However, you must also have a working
+     version of the GNU assembler (GNU as, aka GAS) as it is used as
+     the back-end for GNU CC to produce binary object modules and is
+     not included in the GNU CC sources.  GAS is also needed to compile
+     `libgcc2' in order to build `gcclib' (see above); `make-l2.com'
+     expects to be able to find it operational in
+     `gnu_cc:[000000]gnu-as.exe'.
+
+     To use GNU CC on VMS, you need the VMS driver programs `gcc.exe',
+     `gcc.com', and `gcc.cld'.  They are distributed with the VMS
+     binaries (`gcc-vms') rather than the GNU CC sources.  GAS is also
+     included in `gcc-vms', as is Bison.
+
+     Once you have successfully built GNU CC with VAX C, you should use
+     the resulting compiler to rebuild itself.  Before doing this, be
+     sure to restore the `CC', `CFLAGS', and `LIBS' definitions in
+     `make-cccp.com' and `make-cc1.com'.  The second generation
+     compiler will be able to take advantage of many optimizations that
+     must be suppressed when building with other compilers.
+
+   Under previous versions of GNU CC, the generated code would
+occasionally give strange results when linked with the sharable
+`VAXCRTL' library.  Now this should work.
+
+   Even with this version, however, GNU CC itself should not be linked
+with the sharable `VAXCRTL'.  The version of `qsort' in `VAXCRTL' has a
+bug (known to be present in VMS versions V4.6 through V5.5) which
+causes the compiler to fail.
+
+   The executables are generated by `make-cc1.com' and `make-cccp.com'
+use the object library version of `VAXCRTL' in order to make use of the
+`qsort' routine in `gcclib.olb'.  If you wish to link the compiler
+executables with the shareable image version of `VAXCRTL', you should
+edit the file `tm.h' (created by `vmsconfig.com') to define the macro
+`QSORT_WORKAROUND'.
+
+   `QSORT_WORKAROUND' is always defined when GNU CC is compiled with
+VAX C, to avoid a problem in case `gcclib.olb' is not yet available.
+
+`collect2'
+==========
+
+   Many target systems do not have support in the assembler and linker
+for "constructors"--initialization functions to be called before the
+official "start" of `main'.  On such systems, GNU CC uses a utility
+called `collect2' to arrange to call these functions at start time.
+
+   The program `collect2' works by linking the program once and looking
+through the linker output file for symbols with particular names
+indicating they are constructor functions.  If it finds any, it creates
+a new temporary `.c' file containing a table of them, compiles it, and
+links the program a second time including that file.
+
+   The actual calls to the constructors are carried out by a subroutine
+called `__main', which is called (automatically) at the beginning of
+the body of `main' (provided `main' was compiled with GNU CC).  Calling
+`__main' is necessary, even when compiling C code, to allow linking C
+and C++ object code together.  (If you use `-nostdlib', you get an
+unresolved reference to `__main', since it's defined in the standard
+GCC library.  Include `-lgcc' at the end of your compiler command line
+to resolve this reference.)
+
+   The program `collect2' is installed as `ld' in the directory where
+the passes of the compiler are installed.  When `collect2' needs to
+find the *real* `ld', it tries the following file names:
+
+   * `real-ld' in the directories listed in the compiler's search
+     directories.
+
+   * `real-ld' in the directories listed in the environment variable
+     `PATH'.
+
+   * The file specified in the `REAL_LD_FILE_NAME' configuration macro,
+     if specified.
+
+   * `ld' in the compiler's search directories, except that `collect2'
+     will not execute itself recursively.
+
+   * `ld' in `PATH'.
+
+   "The compiler's search directories" means all the directories where
+`gcc' searches for passes of the compiler.  This includes directories
+that you specify with `-B'.
+
+   Cross-compilers search a little differently:
+
+   * `real-ld' in the compiler's search directories.
+
+   * `TARGET-real-ld' in `PATH'.
+
+   * The file specified in the `REAL_LD_FILE_NAME' configuration macro,
+     if specified.
+
+   * `ld' in the compiler's search directories.
+
+   * `TARGET-ld' in `PATH'.
+
+   `collect2' explicitly avoids running `ld' using the file name under
+which `collect2' itself was invoked.  In fact, it remembers up a list
+of such names--in case one copy of `collect2' finds another copy (or
+version) of `collect2' installed as `ld' in a second place in the
+search path.
+
+   `collect2' searches for the utilities `nm' and `strip' using the
+same algorithm as above for `ld'.
+
+Standard Header File Directories
+================================
+
+   `GCC_INCLUDE_DIR' means the same thing for native and cross.  It is
+where GNU CC stores its private include files, and also where GNU CC
+stores the fixed include files.  A cross compiled GNU CC runs
+`fixincludes' on the header files in `$(tooldir)/include'.  (If the
+cross compilation header files need to be fixed, they must be installed
+before GNU CC is built.  If the cross compilation header files are
+already suitable for ANSI C and GNU CC, nothing special need be done).
+
+   `GPLUS_INCLUDE_DIR' means the same thing for native and cross.  It
+is where `g++' looks first for header files.  `libg++' installs only
+target independent header files in that directory.
+
+   `LOCAL_INCLUDE_DIR' is used only for a native compiler.  It is
+normally `/usr/local/include'.  GNU CC searches this directory so that
+users can install header files in `/usr/local/include'.
+
+   `CROSS_INCLUDE_DIR' is used only for a cross compiler.  GNU CC
+doesn't install anything there.
+
+   `TOOL_INCLUDE_DIR' is used for both native and cross compilers.  It
+is the place for other packages to install header files that GNU CC will
+use.  For a cross-compiler, this is the equivalent of `/usr/include'.
+When you build a cross-compiler, `fixincludes' processes any header
+files in this directory.

+Free Software Redistributors Donate
+***********************************
+
+In adddition to their conference donation, Red Hat Software has agreed to
+donate $1.00 to the FSF for every copy of Red Hat Archives sold.  They have
+also added a GNU logo to the back of that CD with the words "Supports the
+Free Software Foundation".
+
+The SNOW 2.1 CD producers added the words "Includes $5 donation to the FSF"
+to the front of their CD.  Potential buyers will know just how much of the
+price is for the FSF & how much is for the redistributor.
+
+The Sun Users Group Deutschland has made it even clearer: their CD says,
+"Price 90 DM, + 12 DM donation to the FSF." We thank them for their
+contribution to our efforts.
+
+Kyoto Micro Computer of Japan regularly gives us 10% of their GNU-related
+sales.
+
+Mr. Hiroshi, Mr. Kojima, and the other authors of the `Linux Primer' in Japan
+have donated money from the sales of their book.
+
+Infomagic has continued to make sizeable donations to the FSF.
+
+At the request of author Arnold Robbins, Specialized Systems Consultants, Inc.
+continues to donate 3% of their profits from selling `Effective AWK
+Programming'.  We would also like to acknowledge the many SSC authors who
+have donated their royalties and fees to the FSF.
+
+In the long run, the success of free software depends on how much new free
+software people develop.  Free software distribution offers an opportunity to
+raise funds for such development in an ethical way.  These redistributors
+have made use of the opportunity.  Many others let it go to waste.
+
+You can help promote free software development by convincing for-a-fee
+redistributors to contribute--either by doing development themselves or by
+donating to development organizations (the FSF and others).
+
+The way to convince distributors to contribute is to demand and expect this
+of them.  This means choosing among distributors partly by how much they give
+to free software development.  Then you can show distributors they must
+compete to be the one who gives the most.
+
+To make this work, you must insist on numbers that you can compare, such as,
+"We will give ten dollars to the Foobar project for each disk sold." A vague
+commitment, such as "A portion of the profits is donated," doesn't give you a
+basis for comparison.  Even a precise fraction "of the profits from this
+disk" is not very meaningful, since creative accounting and unrelated
+business decisions can greatly alter what fraction of the sales price counts
+as profit.
+
+Also, press developers for firm information about what kind of development
+they do or support.  Some kinds make much more long-term difference than
+others.  For example, maintaining a separate version of a GNU program
+contributes very little; maintaining a program on behalf of the GNU Project
+<contributes much.  Easy new ports contribute little, since someone else
+would surely do them; difficult ports such as adding a new CPU to the GNU
+compiler or Mach contribute more; major new features & programs contribute
+the most.
+
+By establishing the idea that supporting further development is "the proper
+thing to do" when distributing free software for a fee, we can assure a
+steady flow of resources for making more free software.
+
+ 
+
+Help from Free Software Companies
+*********************************
+
+When choosing a free software business, ask those you are considering how
+much they do to assist free software development, e.g., by contributing money
+to free software development or by writing free software improvements
+themselves for general use.  By basing your decision partially on this
+factor, you can help encourage those who profit from free software to
+contribute to its growth.
+
+Wingnut (SRA's special GNU support group) regularly donates a part of its

+
+Major Changes in GNU Software and Documentation
+***********************************************
+
+   * Hurd Progress   (Also *note What Is the Hurd::.)
+
+     We have made two test releases of the Hurd, and we will make another
+     (version 0.2) in this month.  Stability is improving, and we have begun
+     modifying various user-level utilities to understand new Hurd filesystem
+     features (fileutils, shellutils, tar, etc.).
+
+     One way for people to help out is to compile and run as much third-party
+     free software as they can; in this way we can find bugs and deficiencies
+     with some rapidity.  Volunteers with a PC are therefore eagerly sought
+     to get the new 0.2 release and compile their favorite Unix programs and
+     games.
+
+   * GNU System Progress
+
+     Version 0.2 of the GNU system will be released in this month, to coincide
+     with the 0.2 release of the Hurd.  This complete GNU system is available
+     by FTP.  We are working with Ian Murdock to develop an excellent package
+     management system for GNU.  This will make administering and upgrading
+     the system much easier.  Because of features only the Hurd has, the GNU
+     package management system will be simpler and more featureful than
+     similar package systems for various GNU/Linux distributions.
+
+   * New Source Code CD!   (See *Note January 1997 Source Code CD-ROMs::)
+
+     We are releasing the January 1997 (Edition 9) Source Code CD-ROM this
+     month.  Once again, it is a two disk set.  It includes several new
+     programs: `gforth', `gpc', <Meta-HTML>, `stow', `units', VRweb, `wget',
+     `windows32api', and `xinfo'.  On the CD-ROMs are full distributions of
+     X11R6.3, MIT Scheme, Emacs, GCC, and current versions of all other GNU
+     Software.  *Note GNU Software::, for more about these packages.
+
+   * New Compiler Tools CD-ROM  
+
+     We are releasing the January 1997 (Edition 4) Compiler Tools Binaries
+     CD.  Support is included for several new operating systems.
+
+     The Compiler Tools Binaries CD-ROM contains executables of the GNU
+     compiler tools for some systems that don't normally come with a
+     compiler.  This allows users of those systems to compile their own
+     software without having to buy a proprietary compiler.
+
+     We hope to include more systems with each update of this CD-ROM.  If you
+     can help build binaries for new systems or have one to suggest, please
+     contact us at either address on the top menu.  For more information, see
+     *Note Compiler Tools Binaries CD-ROM::.
+
+   * New/Updated Manuals since Last Bulletin   (See *Note Documentation::)
+
+     Since the last bulletin, we have published new editions of: `Debugging
+     with GDB', for version 4.16 with a new color cover; `Texinfo' Manual,
+     edition 2.24; & the `GNU Emacs Manual', for version 19.33 with a new
+     color cover.  `Using and Porting GNU CC' has been re-printed in a
+     lay-flat bound edition with a new color cover.  A new Bison Manual with
+     a new color cover is planned.
+
+   * Give to GNU the United Way!
+
+     As a 501(c)3 tax-exempt organization, the FSF is eligible to receive
+     United Way funds.  When donating to United Way, one can specify that all
+     or part of the donation be directed to the FSF.  On the donor form,
+     check the "Specific Requests" box and include the sentence, "Send my
+     gift to the Free Software Foundation, 59 Temple Place, Suite 330,
+     Boston, MA 02111." We especially appreciate the donations from Microsoft
+     matching the United Way donations of their employees.  Also see *Note
+     Donations Translate Into Free Software:: and *Note Cygnus Matches
+     Donations!::.
+
+   * GNU Software Works on MS-DOS   (Also *note GNU Software::.)
+
+     GNU Emacs 19 and many other GNU programs have been ported to MS-DOS for
+     i386/i486/Pentium machines.  We ship binaries & sources on the *Note
+     Compiler Tools Binaries CD-ROM::.
+
+   * MULE Merge Almost Complete
+
+     MULE is the Multi-Lingual Emacs developed by Ken'ichi Handa at the
+     Electro-Technical Lab in Tsukuba, Japan.  Handa has readied the code for
+     merging into Emacs and we expect to complete the merge soon.
+
+   * GCC   (For current status on GCC and GNAT, *note GNU Software::.)
+
+     New front ends for GCC are being done for Pascal & Chill.  Pascal,
+     `gpc', stagnated for some years, but should be released by the time you
+     read this.  See `http://agnes.dida.physik.uni-essen.de/~gnu-pascal'.
+
+   * GUILE
+
+     GUILE is currently available as a test release.  GNU's Ubiquitous
+     Intelligent Language for Extension is an SCM-based library that can make
+     any ordinary C program extensible.  (For SCM info, see "JACAL" in *Note
+     GNU Software::.)
+
+     Also being developed are SCSH-compatible system call & Tk interfaces, a
+     module system, dynamic linking support, & a byte-code interpreter.
+     Support for Emacs Lisp & a more C-like language is coming.
+
+   * Texinfo   (For current status, *note GNU Software::.)
+
+     Texinfo now provides macro facilities and supports multicolumn tables.
+     It comes with an `install-info' program that packages can use to update
+     the `dir' file automatically when they install their Info files.
+
+   * GNU Common Lisp   (For current status, *note GNU Software::.)
+
+     Version 2.2.1 of GNU Common Lisp (GCL) was released in December '96.  It
+     now includes a graphical interface to the Tk widget system.  All
+     documentation is now Texinfo-based, with built-in regexp matching used
+     to access the documentation.  A first pass at the Common Lisp condition
+     system is also included.  Version 2.2.1 contains mainly updates to allow
+     GCL 2.2 to work correctly with current operating system levels, and to
+     fix bugs.  Volunteers to help with the move to the ANSI standard are
+     most welcome; please contact `schelter@math.utexas.edu'.
+
+   * Experimental Electronic Cash
+
+     `http://www.lysator.liu.se/~nisse/NCash' is an experimental
+     implementation of anonymous electronic cash which is to be released as
+     free software.
+
+   * HTML Professional and GPL
+
+     The recent development and release of HTML Professional was made under
+     the terms of the GNU GPL.  In order to facilitate distribution, the GPL
+     text was re-encoded into this more recent version of HTML, and is now
+     distributed with HTML Pro.  An online copy can be retrieved at
+     `http://www.arbornet.org/~silmaril/dtds/html/gnugpl.html'.
+
+     HTML Pro is an unofficial version of the HTML DTD.  HTML Pro is
+     distributed for discussion by the `www-html' mailing list.  It
+     composites all other known versions, and allows World Wide Web designers
+     to use recent experimental additions in a rational and structured manner.
+     It comes with a `.ced' file for GNU Emacs/psgml-mode and can be gotten at
+     `ftp://www.ucc.ie/pub/html/htmlpro.{zip|tar.gz|zip.hqx}'.
+     Documentation is at
+     `http://www.arbornet.org/~silmaril/dtds/html/htmlpro.html'.
+
+   * Meta-HTML 5.01 Source Release
+
+     Version 5.01 of Universal Access Inc.'s <Meta-HTML> is now available.
+
+     <Meta-HTML> is a programming language specifically designed to work
+     within the environment of the World Wide Web.  Although it is a genuine
+     programming language, suitable for large-scale symbolic manipulation,
+     <Meta-HTML> also provides the most commonly wanted Web functionality as
+     built-in primitives, so you don't have to write them.  You can find out
+     more about the theory of implementation in this white paper
+     `http://www.metahtml.com/meta-html/manifesto.html'.
+
+     Web pages are authored using HTML and <Meta-HTML> statements freely
+     intermixed.  When a page is requested by a browser, the page is passed
+     through the <Meta-HTML> engine, which dynamically processes any
+     <Meta-HTML> statements to produce a final HTML page which is delivered
+     to the browser.
+
+     The source distribution provides several different interpreter options:
+     a CGI engine which can be run by any Unix Web server; a full-featured
+     Web server (mhttpd) with the interpreter built in; a standalone
+     processor, much like Perl or Tcl; and an interactive debugger, with a
+     feel similar to GDB (mdb).
+
+     There is a user mailing list: `metahtml-users@metahtml.com'.  You can
+     subscribe on the Web at `http://www.metahtml.com/E-Mail/', or by sending
+     mail to `metahtml-users-request@metahtml.com'.
+
+     Pre-compiled distribution sets for some systems are available via the
+     <Meta-HTML> Web site at `http://www.metahtml.com'.
+
+   * VRweb Browser
+
+     VRweb, a browser for 3D models on the Web written in the Virtual Reality
+     Modeling Language (VRML), is now available under the GPL.  VRweb works
+     in conjunction with Web browsers on Unix & Windows platforms.
+
+     VRweb is a joint project of IICM (home of Hyper-G), NCSA (home of
+     Mosaic), & the University of Minnesota (home of Gopher).  The software
+     is freely available in binary & source.  VRweb 1.2 for Unix has just
+     been released, VRweb 1.2 for Windows will follow in due course.  You can
+     download VRweb from `ftp://iicm.tu-graz.ac.at/pub/Hyper-G/VRweb/UNIX'
+     and numerous mirror sites.  Further information on VRweb can be found at
+     `http://hyperg.iicm.tu-graz.ac.at/vrweb'.
+
+     VRML is a non-proprietary, platform-independent file format for 3D
+     graphics on the Internet.  Also see `http://www.sdsc.edu/vrml/',  the
+     VRML Repository.
+
+
+
+The Deluxe Distribution
+***********************
+
+The Free Software Foundation has been asked repeatedly to create a package
+that provides executables for all of our software.  Normally we offer only
+sources.  The Deluxe Distribution provides binaries with the source code and
+includes six T-shirts, all our CD-ROMs, printed manuals, & reference cards.
+
+The FSF Deluxe Distribution contains the binaries and sources to hundreds of
+different programs including Emacs, the GNU C/C++ Compiler, the GNU Debugger,
+the complete X Window System, and all the GNU utilities.
+
+We will make a Deluxe Distribution for most machines/operating systems.  We
+may be able to send someone to your office to do the compilation, if we can't
+find a suitable machine here.  However, we can only compile the programs that
+already support your chosen machine/system - porting is a separate matter.
+(To commission a port, see the GNU Service Directory; details in *Note Free
+Software Support::.) Compiling all these programs takes time; a Deluxe
+Distribution for an unusual machine will take longer to produce than one for
+a common machine.  Please contact the FSF Office with any questions.
+
+We supply the software on a write-once CD-ROM (in ISO 9660 format with "Rock
+Ridge" extensions), or on one of these tapes in Unix `tar' format: 1600 or
+6250bpi 1/2in reel, Sun DC300XLP 1/4in cartridge - QIC24, IBM RS/6000 1/4in
+c.t. - QIC 150, Exabyte 8mm c.t., or DAT 4mm c.t.  If your computer cannot
+read any of these, please contact us to see if we can handle your format.
+
+The manuals included are one each of `Bison', `Calc', `GAWK', `GCC', `GNU C
+Library', `GDB', `Flex', `GNU Emacs Lisp Reference', `Programming in Emacs
+Lisp: An Introduction', `Make', `Texinfo', & `Termcap' manuals; six copies of
+the `GNU Emacs' manual; and ten reference cards each for Emacs, Bison, Calc,
+Flex, & GDB.
+
+Every Deluxe Distribution also has a copy of the latest editions of our
+CD-ROMs that have sources of our software & compiler tool binaries for some
+systems.  The CDs are in ISO 9660 format with Rock Ridge extensions.
+
+The price of the Deluxe Distribution is $5000 (shipping included).  These
+sales provide enormous financial assistance to help the FSF develop more free
+software.  To order, please fill out the "Deluxe Distribution" section on the
+*note Free Software Foundation Order Form::.  and send it to:

+
+GNU Documentation
+*****************
+
+GNU is dedicated to having quality, easy-to-use online & printed
+documentation.  GNU manuals are intended to explain underlying concepts,
+describe how to use all the features of each program, & give examples of
+command use.  GNU manuals are distributed as Texinfo source files, which
+yield both typeset hardcopy via the TeX document formatting system and online
+hypertext display via the menu-driven Info system.  Source for these manuals
+comes with our software; here are the manuals that we publish as printed
+books.  See the *note Free Software Foundation Order Form::., to order them.
+
+Most GNU manuals are bound as soft cover books with "lay-flat" bindings.
+This allows you to open them so they lie flat on a table without creasing the
+binding.  They have an inner cloth spine and an outer cardboard cover that
+will not break or crease as an ordinary paperback will.  Currently, the
+`Using and Porting GNU CC', `GDB', `Emacs', `Emacs Lisp Reference',
+`Programming in Emacs Lisp: An Introduction', `GNU Awk User's Guide', `Make',
+& `Bison' manuals have this binding.  Our other manuals also lie flat when
+opened, using a GBC binding.  Our manuals are 7in by 9.25in except the 8.5in
+by 11in `Calc' manual.
+
+The edition number of the manual and version number of the program listed
+after each manual's name were current at the time this Bulletin was published.
+
+`Debugging with GDB' (for Version 4.16) tells how to run your program under
+GNU Debugger control, examine and alter data, modify a program's flow of
+control, and use GDB through GNU Emacs.
+
+The `GNU Emacs Manual' (12th Edition for Version 19.33) describes editing with
+GNU Emacs.  It explains advanced features, including outline mode and regular
+expression search; how to use special programming modes to write languages
+like C++ and TeX; how to use the `tags' utility; how to compile and correct
+code; how to make your own keybindings; and other elementary customizations.
+
+`Programming in Emacs Lisp: An Introduction' (October 1995 Edition 1.04) is
+for people who are not necessarily interested in programming, but who do want
+to customize or extend their computing environment.  If you read it in Emacs
+under Info mode, you can run the sample programs directly.
+
+`The GNU Emacs Lisp Reference Manual' (Edition 2.4 for Version 19.29) and
+`The GNU Emacs Lisp Reference, Japanese Edition' (Japanese Draft Revision
+1.0, from English Edition 2.4 for Version 19.29) cover this programming
+language in depth, including data types, control structures, functions,
+macros, syntax tables, searching/matching, modes, windows, keymaps, byte
+compilation, and the operating system interface.
+
+`The GNU Awk User's Guide' (Edition 1.0 for Version 3.0) tells how to use
+`gawk'.  It is written for those who have never used `awk' and describes
+features of this powerful string and record manipulation language.  It
+clearly delineates those features which are part of POSIX `awk' from `gawk'
+extensions, providing a comprehensive guide to `awk' program portability.
+
+`GNU Make' (Edition 0.50 for Version 3.75 Beta) describes GNU `make', a
+program used to rebuild parts of other programs.  The manual tells how to
+write "makefiles", which specify how a program is to be compiled and how its
+files depend on each other.  Included are an introductory chapter for novice
+users and a section about automatically generated dependencies.
+
+The `Flex' manual (Edition 1.03 for Version 2.3.7) teaches you to write a
+lexical scanner definition for the `flex' program to create a C++ or C-coded
+scanner that recognizes the patterns defined.  You need no prior knowledge of
+scanners.
+
+`The Bison Manual' (November 1995 Edition for Version 1.25) teaches you how
+to write context-free grammars for the Bison program that convert into
+C-coded parsers.  You need no prior knowledge of parser generators.
+
+`Using and Porting GNU CC' (November 1995 Edition for Version 2.7.2) tells
+how to run, install, and port the GNU C Compiler to new systems.  It lists
+new features and incompatibilities of GCC, but people not familiar with C
+will still need a good reference on the C programming language.  It also
+covers G++.
+
+The `Texinfo' manual (Edition 2.24 for Version 3) explains the markup
+language that produces our online Info documentation & typeset hardcopies.
+It tells you how to make tables, lists, chapters, nodes, accented & special
+characters, indexes, cross references, & how to catch mistakes.
+
+`The Termcap Manual' (3rd Edition for Version 1.3), often described as "twice
+as much as you ever wanted to know about termcap," details the format of the
+termcap database, the definitions of terminal capabilities, and the process
+of interrogating a terminal description.  This manual is primarily for
+programmers.
+
+The `C Library Reference Manual' (Edition 0.08 for Version 2.0) describes the
+library's facilities, including both what Unix calls "library functions" &
+"system calls."  We are doing small copier runs of this manual until it
+becomes more stable.  Please send fixes to `bug-glibc-manual@prep.ai.mit.edu'.
+
+The `Emacs Calc Manual' (for Version 2.02) is both a tutorial and a reference
+manual.  It tells how to do ordinary arithmetic, how to use Calc for algebra,
+calculus, and other forms of mathematics, and how to extend Calc.
+
+ 
+
+GNU Software
+************
+
+All our software is available via FTP; see *Note How to Get GNU Software::.
+We also offer *Note CD-ROMs::, and printed *Note Documentation::, which
+includes manuals and reference cards.  In the articles describing the
+contents of each medium, the version number listed after each program name
+was current when we published this Bulletin.  When you order a newer CD-ROM,
+some of the programs may be newer and therefore the version number higher.
+See the *note Free Software Foundation Order Form::., for ordering
+information.
+
+Some of the contents of our FTP distributions are compressed.  We have
+software on our FTP sites to uncompress these files.  Due to patent troubles
+with `compress', we use another compression program, `gzip'.  (Such
+prohibitions on software development are fought by the League for Programming
+Freedom; *note What Is the LPF::., for details.)
+
+You may need to build GNU `make' before you build our other software.  Some
+vendors supply no `make' utility at all and some native `make' programs lack
+the `VPATH' feature essential for using the GNU configure system to its full
+extent.  The GNU `make' sources have a shell script to build `make' itself on
+such systems.
+
+We welcome all bug reports and enhancements sent to the appropriate
+electronic mailing list (*note Free Software Support::.).
+
+ 
+
+Configuring GNU Software
+------------------------
+
+We are using Autoconf, a uniform scheme for configuring GNU software packages
+in order to compile them (see "Autoconf" and "Automake" below, in this
+article).  The goal is to have all GNU software support the same alternatives
+for naming machine and system types.
+
+Ultimately, it will be possible to configure and build the entire system all
+at once, eliminating the need to configure each individual package separately.
+
+You can also specify both the host and target system to build
+cross-compilation tools.  Most GNU programs now use Autoconf-generated
+configure scripts.
+
+ 
+
+GNU Software Now Available
+--------------------------
+
+For future programs and features, see *Note Forthcoming GNUs::.
+
+Key to cross reference:
+
+        BinCD        January 1997 Binaries CD-ROM
+        SrcCD        January 1997 Source CD-ROMs
+
+[FSFman] shows that we sell a manual for that package.  [FSFrc] shows we sell
+a reference card for that package.  To order them, see the *note Free
+Software Foundation Order Form::.  *Note Documentation::, for more
+information on the manuals.  Source code for each manual or reference card is
+included with each package.
+
+   * `acm'   (SrcCD)
+
+     `acm' is a LAN-oriented, multiplayer, aerial combat simulation that runs
+     under the X Window System.  Players engage in air to air combat against
+     one another using heat seeking missiles and cannons.  We are working on
+     a more accurate simulation of real airplane flight characteristics.
+
+   * Apache   *Also see* `http://www.apache.org/'   (SrcCD)
+
+     Apache is an HTTP server designed as a successor to the NCSA family of
+     web servers.  It adds a significant amount of new functionality, has an
+     extensive API for modular enhancements, is extremely flexible without
+     compromising speed, and has an active development group and user
+     community.
+
+   * Autoconf   (SrcCD)
+
+     Autoconf produces shell scripts which automatically configure source code
+     packages.  These scripts adapt the packages to many kinds of Unix-like
+     systems without manual user intervention.  Autoconf creates a script for
+     a package from a template file which lists the operating system features
+     which the package can use, in the form of `m4' macro calls.  Autoconf
+     requires GNU `m4' to operate, but the resulting configure scripts it
+     generates do not.
+
+   * Automake   (SrcCD)
+
+     Automake is a tool for generating `Makefile.in's for use with Autoconf.
+     The generated makefiles are compliant with GNU Makefile standards.
+
+   * BASH   (SrcCD)
+
+     GNU's shell, BASH (Bourne Again SHell), is compatible with the Unix `sh'
+     and offers many extensions found in `csh' and `ksh'.  BASH has job
+     control, `csh'-style command history, command-line editing (with Emacs
+     and `vi' modes built-in), and the ability to rebind keys via the
+     `readline' library.  BASH conforms to the POSIX 1003.2-1992 standard.
+
+   * `bc'   (SrcCD)
+
+     `bc' is an interactive algebraic language with arbitrary precision
+     numbers.  GNU `bc' follows the POSIX 1003.2-1992 standard with several
+     extensions, including multi-character variable names, an `else'
+     statement, and full Boolean expressions.  The RPN calculator `dc' is now
+     distributed as part of the same package, but GNU `bc' is not implemented
+     as a `dc' preprocessor.
+
+   * BFD   (BinCD, SrcCD)
+
+     The Binary File Descriptor library allows a program which operates on
+     object files (e.g., `ld' or GDB) to support many different formats in a
+     clean way.  BFD provides a portable interface, so that only BFD needs to
+     know the details of a particular format.  One result is that all
+     programs using BFD will support formats such as a.out, COFF, and ELF.
+     BFD comes with Texinfo source for a manual (not yet published on paper).
+
+     At present, BFD is not distributed separately; it is included with
+     packages that use it.
+
+   * Binutils   (BinCD, SrcCD)
+
+     Binutils includes these programs: `ar', `c++filt', `demangle', `gas',
+     `gprof', `ld', `nlmconv', `nm', `objcopy', `objdump', `ranlib', `size',
+     `strings', & `strip'.
+
+     Binutils version 2 uses the BFD library.  The GNU assembler, `gas',
+     supports the a29k, Alpha, H8/300, H8/500, HP-PA, i386, i960, m68k, m88k,
+     MIPS, NS32K, SH, SPARC, Tahoe, Vax, and Z8000 CPUs, and attempts to be
+     compatible with many other assemblers for Unix and embedded systems.  It
+     can produce mixed C and assembly listings, and includes a macro facility
+     similar to that in some other assemblers.  GNU's linker, `ld', emits
+     source-line numbered error messages for multiply-defined symbols and
+     undefined references, and interprets a superset of AT&T's Linker Command
+     Language, which gives control over where segments are placed in memory.
+     `nlmconv' converts object files into Novell NetWare Loadable Modules.
+     `objdump' can disassemble code for most of the CPUs listed above, and
+     can display other data (e.g., symbols and relocations) from any file
+     format read by BFD.
+
+   * Bison   *See *Note Documentation::* (BinCD, SrcCD)   [FSFman, FSFrc]
+
+     Bison is an upwardly compatible replacement for the parser generator
+     `yacc'.  Texinfo source for the `Bison Manual' and reference card are
+     included.
+
+   * C Library   *See *Note Forthcoming GNUs::*   (BinCD, SrcCD)   [FSFman]
+
+     The GNU C library supports ISO C-1989, ISO C/amendment 1-1995, POSIX
+     1003.1-1990, POSIX 1003.1b-1993, POSIX 1003.1c-1995 (when the underlying
+     system permits), & most of the functions in POSIX 1003.2-1992.  It is
+     nearly compliant with the extended XPG4.2 specification which guarantees
+     upward compatibility with 4.4BSD & many System V functions.
+
+     When used with the GNU Hurd, the C Library performs many functions of the
+     Unix system calls directly.  Mike Haertel has written a fast `malloc'
+     which wastes less memory than the old GNU version.
+
+     GNU `stdio' lets you define new kinds of streams, just by writing a few
+     C functions.  Two methods for handling translated messages help writing
+     internationalized programs & the user can adopt the environment the
+     program runs in to conform with local conventions.  Extended `getopt'
+     functions are already used to parse options, including long options, in
+     many GNU utilities.  The name lookup functions now are modularized which
+     makes it easier to select the service which is needed for the specific
+     database & the document interface makes it easy to add new services.
+     Texinfo source for the `GNU C Library Reference Manual' is included
+     (*note Documentation::.).
+
+     Previous versions of the GNU C library ran on a large number of systems.
+     The architecture-dependent parts of the C library have not been updated
+     since development on version 2.0 started, so today it runs out of the
+     box only on GNU/Hurd (all platforms GNU/Hurd also runs on) & GNU/Linux
+     (ix86, Alpha, m68k, work is in progress for MIPS & Sparc).  Other
+     architectures will become available again as soon as somebody does the
+     port.
+
+   * C++ Library   (BinCD, SrcCD)
+
+     The GNU C++ library (libg++) contains an extensive collection of
+     container and utility classes, including Obstacks, multiple-precision
+     Integers and Rationals, Complex numbers, BitSets, and BitStrings.
+
+     The distribution also includes the libstdc++ library.  This implements
+     library facilities defined by the forthcoming ANSI/ISO C++ standard,
+     including strings, the iostream library, and a port of the Standard
+     Template Library.
+
+   * Calc   (SrcCD)   [FSFman, FSFrc]
+
+     Calc (written by Dave Gillespie in Emacs Lisp) is an extensible, advanced
+     desk calculator & mathematical tool that runs as part of GNU Emacs.  You
+     can use Calc as a simple four-function calculator, but it has many more
+     features including: choice of algebraic or RPN (stack-based) entry;
+     logarithmic, trigonometric, & financial functions; arbitrary precision;
+     complex numbers; vectors; matrices; dates; times; infinities; sets;
+     algebraic simplification; & differentiation & integration.  It outputs to
+     `gnuplot', & comes with source for a manual & reference card (*note
+     Documentation::.).
+
+   * `cfengine'   (SrcCD)
+
+     `cfengine' is used to maintain site-wide configuration of a
+     heterogeneous Unix network using a simple high level language.  Its
+     appearance is similar to `rdist', but allows many more operations to be
+     performed automatically.  See Mark Burgess, "A Site Configuration
+     Engine", `Computing Systems', Vol. 8, No. 3 (ask `office@usenix.org' how
+     to get a copy).
+
+   * Chess   (SrcCD)
+
+     GNU Chess lets most modern computers play a full game of chess.  It has
+     a plain terminal interface, a curses interface, & the unique X Windows
+     interface `xboard'.  Best results are obtained using GNU C to compile
+     GNU Chess.
+
+     Recent improvements include "configure"-capability, correct thinking on
+     opponent's time, makefile for Windows NT, full Windows 95/NT
+     compatibility, parallel Unix & Windows 95/NT versions, major crash bug
+     fix & various other minor improvements & bug fixes.
+
+     Stuart Cracraft founded GNU Chess & is the project lead for the 10+ year
+     history of GNU Chess.  Acknowledgements for this past year's work

+
+   * CLISP   (SrcCD)
+
+     CLISP is a Common Lisp implementation by Bruno Haible & Michael Stoll.
+     It mostly supports the Lisp described by `Common LISP: The Language (2nd
+     edition)' & the ANSI Common Lisp standard.  CLISP includes an
+     interpreter, a byte-compiler, a large subset of CLOS & a foreign language
+     interface.  The user interface language (English, German, French) can be
+     chosen at run time.  An X11 API is available through CLX & Garnet.
+     CLISP needs only 2 MB of memory & runs on many microcomputers (including
+     MS-DOS systems, OS/2, Windows NT, Windows 95, Amiga 500-4000, & Acorn
+     RISC PC) & all kinds of Unix systems.
+
+   * Common Lisp   *Also *note GNUs Flashes::.*   (SrcCD)
+
+     GNU Common Lisp (GCL, formerly known as Kyoto Common Lisp) is a compiler
+     & interpreter for Common Lisp.  GCL is very portable & extremely
+     efficient on a wide class of applications, & compares favorably in
+     performance with commercial Lisps on several large theorem-prover &
+     symbolic algebra systems.  GCL supports the CLtL1 specification but is
+     moving towards the proposed ANSI standard.
+
+     GCL compiles to C & then uses the native optimizing C compiler (e.g.,
+     GCC).  A function with a fixed number of args & one value turns into a C
+     function of the same number of args, returning one value--so GCL is
+     maximally efficient on such calls.  Its conservative garbage collector
+     gives great freedom to the C compiler to put Lisp values in registers.
+     It has a source level Lisp debugger for interpreted code & displays
+     source code in an Emacs window.  Its profiler (based on the C profiling
+     tools) counts function calls & the time spent in each function.
+
+     There is now a built-in interface to the Tk widget system.  It runs in a
+     separate process, so users may monitor progress on Lisp computations or
+     interact with running computations via a windowing interface.
+
+     There is also an Xlib interface via C (xgcl-2).  CLX runs with GCL, as
+     does PCL (see "PCL" later in this article).
+
+     GCL version 2.2.1 is released under the GNU Library General Public
+     License.
+
+   * CLX   (SrcCD)
+
+     CLX is an X Window interface library for GCL.  This is separate from the
+     built-in TK interface.
+
+   * `cpio'   (SrcCD)
+
+     `cpio' is an archive program with all the features of SVR4 `cpio',
+     including support for the final POSIX 1003.1 `ustar' standard.  `mt', a
+     program to position magnetic tapes, is included with `cpio'.
+
+   * CVS   (SrcCD)
+
+     CVS is a version control system (like RCS or SCCS) which allows you to
+     keep old versions of files (usually source code), keep a log of who,
+     when, and why changes occurred, etc.  It handles multiple developers,
+     multiple directories, triggers to enable/log/control various operations,
+     and can work over a wide area network.  It does not handle build
+     management or bug-tracking; these are handled by `make' and GNATS,
+     respectively.
+
+   * DejaGnu   (SrcCD)
+
+     DejaGnu is a framework to test programs with a single front end for all
+     tests.  DejaGnu's flexibility & consistency makes it easy to write tests.
+     DejaGnu will also work with remote hosts and embedded systems.
+
+     DejaGnu comes with `expect', which runs scripts to conduct dialogs with
+     programs.
+
+   * Diffutils   (SrcCD)
+
+     GNU `diff' compares files showing line-by-line changes in several
+     flexible formats.  It is much faster than traditional Unix versions.  The
+     Diffutils package has `diff', `diff3', `sdiff', & `cmp'.  Future plans
+     include support for internationalization (e.g., error messages in
+     Chinese) & some non-Unix PC environments, & a library interface that can
+     be used by other free software.
+
+   * DJGPP   *Also see "GCC" in this article*   (BinCD)
+
+     DJ Delorie has ported GCC/G++ to i386s running DOS.  DJGPP has a 32-bit
+     i386 DOS extender with a symbolic debugger, development libraries, &
+     ports of Bison, `flex', & Binutils.  Full source code is provided.  It
+     needs at least 5MB of hard disk space to install & 512K of RAM to use.
+     It supports SVGA (up to 1024x768), XMS & VDISK memory allocation,
+     `himem.sys', VCPI (e.g., QEMM, DESQview, & 386MAX), & DPMI (e.g.,
+     Windows 3.x, OS/2, QEMM, & QDPMI).  Version 2 was released in Feb. 1996,
+     & needs a DPMI environment; a free DPMI server is included.
+
+     FTP from `ftp.simtel.net' in `/pub/simtelnet/gnu/djgpp/' (or a SimTel
+     mirror site).
+
+     Ask `listserv@delorie.com', to join a DJGPP users mailing list.
+
+   * `dld'   (SrcCD)
+
+     `dld' is a dynamic linker written by W. Wilson Ho.  Linking your program
+     with the `dld' library allows you to dynamically load object files into
+     the running binary.  `dld' supports a.out object types on the following
+     platforms: Convex C-Series (BSD), i386/i486/Pentium (GNU/Linux), Sequent
+     Symmetry i386 (Dynix 3), Sun-3 (SunOS 3 & 4), Sun-4 (SunOS 4), & VAX
+     (Ultrix).
+
+   * `doschk'   (SrcCD)
+
+     This program is a utility to help software developers ensure that their
+     source file names are distinguishable on System V platforms with
+     14-character filenames and on MS-DOS systems with 8+3 character
+     filenames.
+
+   * `ed'   (SrcCD)
+
+     `ed' is the standard text editor.  It is line-oriented and can be used
+     interactively or in scripts.
+
+   * Elib   (SrcCD)
+
+     Elib is a small library of Emacs Lisp functions, including routines for
+     using AVL trees and doubly-linked lists.
+
+   * Elisp archive   (SrcCD)
+
+     This is a snapshot of Ohio State's GNU Emacs Lisp FTP Archive.  FTP it
+     from `archive.cis.ohio-state.edu' in `/pub/gnu/emacs/elisp-archive'.
+
+   * Emacs   *Also *note Forthcoming GNUs::.*   [FSFman(s), FSFrc]
+
+     In 1975, Richard Stallman developed the first Emacs, an extensible,
+     customizable real-time display editor & computing environment.  GNU Emacs
+     is his second implementation.  It offers true Lisp--smoothly integrated
+     into the editor--for writing extensions & provides an interface to the X
+     Window System.  It runs on Unix, MS-DOS, & Windows NT or 95.  In
+     addition to its powerful native command set, Emacs can emulate the
+     editors vi & EDT (DEC's VMS editor).  Emacs has many other features which
+     make it a full computing support environment.  Source for the `GNU Emacs
+     Manual' & a reference card comes with the software.  Sources for the
+     `GNU Emacs Lisp Reference Manual', & `Programming in Emacs Lisp: An
+     Introduction' are distributed in separate packages.  *Note
+     Documentation::.
+
+   * Emacs 19   (SrcCD)   [FSFman(s), FSFrc]
+
+     Emacs 19 works with character-only terminals & with the X Window System
+     (with or without an X toolkit).  Features new to Emacs 19 include:
+     multiple X windows ("frames" to Emacs), with a separate X window for the
+     minibuffer or a minibuffer attached to each X window; use of the X
+     toolkit; interfacing with the X resource manager; property lists
+     associated with regions of text in a buffer; multiple fonts & colors
+     defined by those properties; simplified/improved processing of function
+     keys, mouse movement & clicks; X selection processing, including
+     clipboard selections; hooks to be run if the point or mouse moves
+     outside a certain range; menu bars & popup menus defined by keymaps;
+     scrollbars; before- & after-change hooks; a source-level debugger for
+     Emacs Lisp programs; floating point numbers; improved buffer allocation,
+     including returning storage to the system when a buffer is killed; many
+     updated libraries; Autoconf-based configuration; support for version
+     control systems (CVS, RCS, & SCCS); & European character sets.
+
+     Features added recently to Emacs 19 include the ability to open frames
+     on more than one X display from a single Emacs job, operation under
+     MS-DOS, MS Windows, and Windows NT, displaying multiple views of an
+     outline at the same time, Lisp-level timers for real time and idle time,
+     version control support for CVS and for multiple branches, text
+     properties for formatting text, commands to edit text properties and
+     save them in files, and GNU-standard long-named command line options.
+     Also see *Note Forthcoming GNUs::.
+
+     Emacs 19 works on: Acorn RISC (RISCiX); Alliant FX/2800 (BSD); Alpha

+
+   * Emacs 18   (SrcCD)   [FSFrc]
+
+     Emacs 18 is several years old.  We no longer maintain it, but still
+     distribute it for those using platforms which Emacs 19 does not support:
+     Alliant FX/80, Altos 3068, Amdahl (UTS), AT&T (3Bs & 7300 PC), CCI 5/32
+     & 6/32, Celerity, DEC (VAX VMS), Dual, Encore (APC, DPC, & XPC), HLH
+     Orion (original & 1/05), ISI (Optimum V, 80386), Masscomp, NCR Tower 32
+     (SVR2 & SVR3), Nixdorf Targon 31, Nu (TI & LMI), pfa50, Plexus, Prime
+     EXL, Stride (system rel. 2), Tahoe, Tandem Integrity S2, Tektronix 16000,
+     Triton 88, Ustation E30 (SS5E), Whitechapel (MG1), & Wicat.
+
+   * `es'   (SrcCD)
+
+     `es' is an extensible shell (based on `rc') with first-class functions,
+     lexical scope, exceptions, and rich return values (i.e., functions can
+     return values other than just numbers).  `es''s extensibility comes from
+     the ability to modify and extend the shell's built-in services, such as
+     path searching and redirection.  Like `rc', it is great for both
+     interactive use and scripting, particularly since its quoting rules are
+     much less baroque than the C and Bourne shells.
+
+   * `enscript'   (SrcCD)
+
+     `enscript' is an upwardly-compatible replacement for the Adobe
+     `enscript' program.  It formats ASCII files (outputting in Postscript)
+     and stores generated output to a file or sends it directly to the
+     printer.
+
+   * Exim   (SrcCD)
+
+     Exim is a new Internet mail transfer agent, similar in style to Smail 3.
+     It can handle relatively high volume mail systems, header rewriting,
+     control over which hosts/nets may use it as a relay, blocking of
+     unwanted mail from specified hosts/nets/senders, and multiple local
+     domains on one mail host ("virtual domains") with several options for
+     the way these are handled.
+
+   * `f2c'   *Also see "Fortran" below & in *Note Forthcoming GNUs::*  
+     (SrcCD)
+
+     `f2c' converts Fortran-77 source into C or C++, which can be compiled
+     with GCC or G++.  Get bug fixes by FTP from site `netlib.bell-labs.com'
+     or by email from `netlib@netlib.bell-labs.com'.  For a summary, see the
+     file `/netlib/f2c/readme.Z'.
+
+   * `ffcall'   (SrcCD)
+
+     `ffcall' is a C library for implementing foreign function calls in
+     embedded interpreters by Bill Triggs and Bruno Haible.  It allows C
+     functions with arbitrary argument lists and return types to be called or
+     emulated (callbacks).
+
+   * Fileutils   (SrcCD)
+
+     The Fileutils are: `chgrp', `chmod', `chown', `cp', `dd', `df', `dir',
+     `dircolors', `du', `install', `ln', `ls', `mkdir', `mkfifo', `mknod',
+     `mv', `rm', `rmdir', `sync', `touch', & `vdir'.
+
+   * Findutils   (SrcCD)
+
+     `find' is frequently used both interactively and in shell scripts to
+     find files which match certain criteria and perform arbitrary operations
+     on them.  Also included are `locate', which scans a database for file
+     names that match a pattern, and `xargs', which applies a command to a
+     list of files.
+
+   * Finger   (SrcCD)
+
+     GNU Finger has more features than other finger programs.  For sites with
+     many hosts, a single host may be designated as the finger "server" host
+     and other hosts at that site configured as finger "clients".  The server
+     host collects information about who is logged in on the clients.  To
+     finger a user at a GNU Finger site, a query to any of its client hosts
+     gets useful information.  GNU Finger supports many customization
+     features, including user output filters and site-programmable output for
+     special target names.
+
+   * `flex'   (BinCD, SrcCD)   [FSFman, FSFrc]
+
+     `flex' is a replacement for the `lex' scanner generator.  `flex' was
+     written by Vern Paxson of the Lawrence Berkeley Laboratory and generates
+     far more efficient scanners than `lex' does.  Sources for the `Flex
+     Manual' and reference card are included (*note Documentation::.).
+
+   * Fortran (`g77')   *Also *note Forthcoming GNUs::.*   (SrcCD)
+
+     GNU Fortran (`g77'), developed by Craig Burley, is available for public
+     beta testing on the Internet.  For now, `g77' produces code that is
+     mostly object-compatible with `f2c' & uses the same run-time library
+     (`libf2c').
+
+   * Fontutils   (SrcCD)
+
+     The Fontutils convert between font formats, create fonts for use with
+     Ghostscript or TeX (starting with a scanned type image & converting the
+     bitmaps to outlines), etc.  It includes: `bpltobzr', `bzrto',
+     `charspace', `fontconvert', `gsrenderfont', `imageto', `imgrotate',
+     `limn', & `xbfe'.
+
+   * GAWK   (SrcCD)   [FSFman]
+
+     GAWK is upwardly compatible with the latest POSIX specification of
+     `awk'.  It also provides several useful extensions not found in other
+     `awk' implementations.  Texinfo source for the `The GNU Awk User's
+     Guide' comes with the software (*note Documentation::.).
+
+   * `gcal'   (SrcCD)
+
+     `gcal' is a program for printing calendars.  It displays different
+     styled calendar sheets, eternal holiday lists, and fixed date warning
+     lists.
+
+   * GCC   *Also *note GNUs Flashes::.*   (BinCD, SrcCD)   [FSFman]
+
+     Version 2 of the GNU C Compiler supports the languages C, C++, and
+     Objective-C; the source file name suffix or a compiler option selects
+     the language.  (Also see "GNAT" later in this article for Ada language
+     supports.) Objective-C support was donated by NeXT.  The runtime support
+     needed to run Objective-C programs is now distributed with GCC (this
+     does not include any Objective-C classes aside from `object', but see
+     "GNUstep" in *Note Forthcoming GNUs::).  As much as possible, G++ is
+     kept compatible with the evolving draft ANSI standard, but not with
+     `cfront' (AT&T's compiler), which has been diverging from ANSI.
+
+     GCC is a fairly portable optimizing compiler which performs many
+     optimizations.  They include: automatic register allocation, common
+     sub-expression elimination (CSE) (including a certain amount of CSE
+     between basic blocks - though not all the supported machine descriptions
+     provide for scheduling or delay slots), invariant code motion from
+     loops, induction variable optimizations, constant propagation, copy
+     propagation, delayed popping of function call arguments, tail recursion
+     elimination, integration of inline functions & frame pointer elimination,
+     instruction scheduling, loop unrolling, filling of delay slots, leaf
+     function optimization, optimized multiplication by constants, the
+     ability to assign attributes to instructions, & many local optimizations
+     automatically deduced from the machine description.
+
+     GCC can open-code most arithmetic on 64-bit values (type `long long
+     int').  It supports extended floating point (type `long double') on the
+     68k; other machines will follow.  GCC supports full ANSI C, traditional
+     C, & GNU C extensions (including: nested functions support, nonlocal
+     gotos, & taking the address of a label).
+
+     GCC can generate a.out, COFF, ELF, & OSF-Rose files when used with a
+     suitable assembler.  It can produce debugging information in these
+     formats: BSD stabs, COFF, ECOFF, ECOFF with stabs, & DWARF.
+
+     GCC generates code for many CPUs, including the a29k, Alpha, ARM, AT&T,
+     DSP1610, Clipper, Convex cN, Elxsi, Fujitsu Gmicro, i370, i860, i960,
+     MIL-STD-1750a, MIPS, ns32k, PDP-11, Pyramid, ROMP, RS/6000, SH, SPUR,
+     Tahoe, VAX, & we32k.
+
+     Position-independent code is generated for the Clipper, Hitachi H8/300,
+     HP-PA (1.0 & 1.1), i386/i486/Pentium, m68k, m88k, SPARC, & SPARClite.
+
+     Operating systems supported include: GNU/Hurd, GNU/Linux, ACIS, AIX, AOS,

+     Using the configuration scheme for GCC, building a cross-compiler is as
+     easy as building a native compiler.
+
+     Version 1 of GCC, G++, & libg++ are no longer maintained.
+
+     Texinfo source for the `Using and Porting GNU CC' manual is included
+     with GCC (*note Documentation::.).
+
+   * GDB   (BinCD, SrcCD)   [FSFman, FSFrc]
+
+     GDB, the GNU DeBugger, is a source-level debugger for C, C++, & Fortran.
+     It provides partial support for  Modula-2 & Chill.
+
+     GDB can debug both C & C++, & will work with executables made by many
+     different compilers; but, C++ debugging will have some limitations if
+     you do not use GCC.
+
+     GDB has a command line user interface, and Emacs has GDB mode as an
+     interface.  Two X interfaces (not distributed or maintained by the FSF)
+     are: `gdbtk' (FTP it from `ftp.cygnus.com' in directory `/pub/gdb'); and
+     `xxgdb' (FTP it from `ftp.x.org' in directory `/contrib/utilities').
+
+     Executable files and symbol tables are read via the BFD library, which
+     allows a single copy of GDB to debug programs with multiple object file
+     formats (e.g., a.out, COFF, ELF).  Other features include a rich command
+     language, remote debugging over serial lines or TCP/IP, and watchpoints
+     (breakpoints triggered when the value of an expression changes).
+
+     GDB uses a standard remote interface to a simulator library which (so
+     far) has simulators for the ARM, Hitachi H8/300, Hitachi H8/500, Hitachi
+     Super-H, PowerPC, WDC 65816, & Zilog Z8001/2.
+
+     GDB can perform cross-debugging.  To say that GDB "targets" a platform
+     means it can perform native or cross-debugging for it.  To say that GDB
+     can "host" a given platform means that it can be built on it, but cannot
+     necessarily debug native programs.
+
+     GDB can:
+
+        * "target" & "host": Amiga 3000 (Amix, NetBSD), DEC Alpha (OSF/1),

+     `Debugging with GDB', and a reference card are included (*note
+     Documentation::.).
+
+   * `gdbm'   (SrcCD)
+
+     `gdbm' is the GNU replacement for the traditional `dbm' and `ndbm'
+     libraries.  It implements a database using quick lookup by hashing.
+     `gdbm' does not ordinarily make sparse files (unlike its Unix and BSD
+     counterparts).
+
+   * `gettext'    *Also *note Help the GNU Translation Project::.*   (SrcCD)
+
+     The GNU `gettext' tool set has everything maintainers need to
+     internationalize a package's user messages.  Once a package has been
+     internationalized, `gettext''s many tools help translators localize
+     messages to their native language and automate handling the translation
+     files.
+
+   * Generic NQS   (SrcCD)
+
+     Generic NQS is a network queuing system for spreading batch jobs across a
+     network of machines.  It is designed to be simple to install on a
+     heterogeneous network of machines, and has optimizations for running on
+     the high end, symmetric multiprocessing servers that are currently on the
+     market.  It is available for many more UNIX variants than any other
+     comparable product, and inter-operates with other NQS systems, including
+     Cray's NQE.
+
+   * `geomview'   *See* `http://www.geom.umn.edu/software/geomview'   (SrcCD)
+
+     `geomview' is an interactive geometry viewing program, for UNIX systems
+     with Motif, using X, GL, or OpenGL graphics.  It allows multiple
+     independently controllable objects and cameras.  `geomview' provides
+     interactive control for motion, appearances (including lighting,
+     shading, and materials), picking on an object, edge or vertex level, and
+     snapshots in PPM or SGI image files, Postscript, and Renderman RIB
+     format.  `geomview' can be controlled through direct mouse manipulation,
+     control panels, and keyboard shortcuts.  External programs can also
+     drive desired aspects of the viewer (such as continually loading
+     changing geometry or controlling the motion of certain objects) while
+     allowing interactive control of everything else.
+
+   * `gforth'   (SrcCD)
+
+     `gforth' is a fast, portable implementation of the ANS Forth language.
+
+   * Ghostscript   (SrcCD)
+
+     Ghostscript is an interpreter for the Postscript and PDF graphics
+     languages.
+
+     The current version of GNU Ghostscript, 3.33, includes nearly a full
+     Postscript Level 2 interpreter and a PDF 1.0 interpreter.  Significant
+     new features include: support for anti-aliased characters; the ability
+     to scan a directory and register all the fonts in it; support for Type 0
+     (Japanese / Chinese / Korean) fonts; and the ability to compile all the
+     external initialization files into the executable.  This version can
+     also run as a 32-bit MS Windows application.
+
+     Thanks to the generosity of URW++ (Hamburg, Germany), the low-quality
+     bitmap-derived fonts distributed with older versions have been replaced
+     with commercial-quality, hinted outline fonts.
+
+     Ghostscript executes commands in the Postscript language by writing
+     directly to a printer, drawing on an X window, or writing to files for
+     printing later or manipulating with other graphics programs.
+
+     Ghostscript includes a C-callable graphics library (for client programs
+     that do not want to deal with the Postscript language).  It also supports
+     i386/i486/Pentiums running DOS with EGA, VGA or SuperVGA graphics (but
+     please do *not* ask the FSF staff any questions about this; we do not
+     use DOS).
+
+   * Ghostview   (SrcCD)
+
+     Tim Theisen, `ghostview@cs.wisc.edu', created Ghostview, a previewer for
+     multi-page files with an X Window interface.  Ghostview & Ghostscript
+     work together; Ghostview creates a viewing window & Ghostscript draws in
+     it.
+
+   * GIT   (SrcCD)
+
+     The GNU Interactive Tools package includes: an extensible file system
+     browser, an ASCII/hex file viewer, a process viewer/killer, & other
+     related utilities & shell scripts.  It can be used to increase the speed
+     & efficiency of many daily tasks, such as copying & moving files &
+     directories, invoking editors, compressing/uncompressing files, creating
+     & expanding archives, compiling programs, sending mail, etc.  It looks
+     nice, has colors (if the standard ANSI color sequences are supported), &
+     is user-friendly.
+
+   * `gmp'   (SrcCD)
+
+     GNU `mp' is a library for arithmetic on arbitrary precision integers,
+     rational numbers, and floating-point numbers.  It has a rich set of

+     upon the paradigm of a central site or organization which receives
+     problem reports and negotiates their resolution by electronic mail.
+     Although it has been used primarily as a software bug-tracking system so
+     far, it is sufficiently generalized that it could be used for handling
+     system administration issues, project management, or any number of other
+     applications.
+
+   * GNUMATH (`gnussl')   (SrcCD)
+
+     GNUMATH is a library (`gnussl') that simplifies scientific programming

+     spreadsheets).  It supports the X Window System and character-based
+     terminals, and can output Embedded Postscript renditions of spreadsheets.
+     Keybindings should be familiar to Emacs users and are configurable.
+     Oleo supports multiple variable-width fonts when used under the X Window
+     System or outputting to Postscript devices.
+
+   * `p2c'   (SrcCD)
+
+     `p2c' is Dave Gillespie's Pascal-to-C translator.  It inputs many

+     It handles multiple input files at once, has TeX compatible output, &
+     outputs readable "KWIC" (KeyWords In Context) indexes without using
+     `nroff'.
+
+     It does not yet handle input files that do not fit in memory all at once.
+
+   * `rc'   (SrcCD)
+
+     `rc' is a shell that features a C-like syntax (much more so than `csh')
+     and far cleaner quoting rules than the C or Bourne shells.  It's
+     intended to be used interactively, but is also great for writing
+     scripts.  It inspired the shell `es'.
+
+   * RCS   (SrcCD)
+
+     RCS, the Revision Control System, is used for version control &
+     management of software projects.  Used with GNU `diff', RCS can handle

+
+   * `recode'    *Also *note Forthcoming GNUs::.*   (SrcCD)
+
+     GNU `recode' converts files between character sets and usages.  When
+     exact transliterations are not possible, it may delete the offending
+     characters or fall back on approximations.  This program recognizes or
+     outputs nearly 150 different character sets and is able to transliterate
+     files between almost any pair.  Most RFC 1345 character sets are
+     supported.
+
+   * `regex'   (SrcCD)
+
+     The GNU regular expression library supports POSIX.2, except for
+     internationalization features.  It is included in many GNU programs which
+     do regular expression matching & is available separately.  An alternate
+     regular expression package, `rx', is faster than `regex' in many cases;
+     we were planning to replace `regex' with `rx', but it is not certain
+     this will happen.
+
+   * Roxen   (SrcCD)
+
+     Roxen is a modularized, object-oriented, non-forking World Wide Web
+     server with high performance and throughput.  It was formerly named
+     Spinner, but was renamed for trademark reasons.
+
+   * `rx'   (SrcCD)
+
+     Tom Lord has written `rx', a new regular expression library which is
+     faster than the older GNU `regex' library.  It is being distributed with
+     `sed'.  `rx' is also an installation option for `fileutils', `id-utils',
+     and `textutils', and maybe for future versions of `cpio', `m4' and `ptx'.
+
+   * SAOimage   (SrcCD)
+
+     SAOimage is an X-based astronomical image viewer.  It reads array data
+     images, which may be in specific formats, and displays them with a

+     colormap, panning and zooming, graphical annotation, and cursor tracking
+     in pixel and sky coordinates, among other features.
+
+   * Scheme   (SrcCD)
+
+     Scheme is a simplified, lexically-scoped dialect of Lisp.  It was
+     designed at MIT and other universities to teach students the art of
+     programming and to research new parallel programming constructs and
+     compilation techniques.
+
+     We now distribute MIT Scheme 7.3, which conforms to the "Revised^4
+     Report On the Algorithmic Language Scheme" (MIT AI Lab Memo 848b), for
+     which TeX source is included.  It is written partly in C, but is
+     presently hard to bootstrap.  Binaries to bootstrap it exist for: HP9000
+     series 300, 400, 700, & 800 (running HP-UX 9.0), NeXT (NeXT OS 2 or 3.2),
+     DEC Alpha (OSF/1), IBM RS/6000 (AIX), Sun-3 or Sun-4 (SunOS 4.1),
+     DECstation 3100/5100 (Ultrix 4.0), Sony NeWS-3250 (NEWS OS 5.01), &
+     Intel i386 (MS-DOS, Windows 3.1 or NT).  If your system isn't on this
+     list & you don't enjoy the bootstrap challenge, see "JACAL" earlier in
+     this article.
+
+   * `screen'   (SrcCD)
+
+     `screen' is a terminal multiplexer that runs several separate "screens"
+     (ttys) on a single character-based terminal.  Each virtual terminal
+     emulates a DEC VT100 plus several ISO 2022 and ISO 6429 (ECMA 48, ANSI
+     X3.64) functions, including color.  Arbitrary keyboard input translation
+     is also supported.  `screen' sessions can be detached and resumed later
+     on a different terminal type.  Output in detached sessions is saved for
+     later viewing.
+
+   * `sed'   (SrcCD)
+
+     `sed' is a stream-oriented version of `ed'.  It comes with the `rx'
+     library.
+
+   * Sharutils   (SrcCD)
+
+     `shar' makes so-called shell archives out of many files, preparing them
+     for transmission by electronic mail services; `unshar' helps unpack
+     these shell archives after reception.  `uuencode' and `uudecode' are
+     POSIX compliant implementations of a pair of programs which transform
+     files into a format that can be safely transmitted across a 7-bit ASCII
+     link.

+   * Shogi   (SrcCD)
+
+     Shogi is a Japanese game similar to Chess; a major difference is that
+     captured pieces can be returned into play.
+
+     GNU Shogi is a variant of GNU Chess; it implements the same features &
+     similar heuristics.  As a new feature, sequences of partial board
+     patterns can be introduced to help the program play toward specific
+     opening patterns.  It has both character and X display interfaces.
+
+     It is primarily supported by Matthias Mutz on behalf of the FSF.
+
+   * SIPP    (SrcCD)

+     the ability to call user-written C code with parameters, an Emacs
+     editing mode, a version of the X protocol invocable from Smalltalk,
+     optional byte-code compilation and/or execution tracing, & automatically
+     loaded per-user initialization files.  It implements all of the classes
+     & protocol in the book "Smalltalk-80: The Language", except for the
+     graphic user interface (GUI) related classes.
+
+   * SNePS    (SrcCD)
+
+     SNePS is the Semantic Network Processing System.  It is an
+     implementation of a fully intensional theory of propositional knowledge
+     representation and reasoning.  SNePS runs under CLISP or GCL.

+CD-ROMs
+*******
+
+We offer these CD-ROMs:
+
+   * Several editions of our *Note Source Code CD-ROMs::.
+
+   * January 1997 *Note Compiler Tools Binaries CD-ROM::.
+
+   * December 1995 Compiler Tools Binaries CD-ROM, see the *note Free
+     Software Foundation Order Form::.
+
+   * December 1994 Compiler Tools Binaries CD-ROM, see the *note Free
+     Software Foundation Order Form::.
+
+   * December 1993 Compiler Tools Binaries CD-ROM, see the *note Free
+     Software Foundation Order Form::.
+
+Our CDs are in ISO 9660 format & can be mounted as a read-only file system on
+most computers.  If your driver supports it, you can mount each CD with "Rock
+Ridge" extensions & it will look like a regular Unix file system, rather than
+one full of truncated & otherwise mangled names that fit vanilla ISO 9660.
+
+You can build most of the software without copying the sources off the CD.
+You only need enough disk space for object files and intermediate build
+targets.
+
+ 
+
+Pricing of the GNU CD-ROMs
+--------------------------
+
+If a business or organization is ultimately paying, the January 1997 Source CD
+set costs $240.  The set costs $60 if you, an individual, are paying out of
+your own pocket.  The January 1997 Compiler Tools Binaries CD-ROM costs $220
+for a business or organization, and $55 for an individual.
+
+ 
+
+What Do the Different Prices Mean?
+..................................
+
+The software on our disks is free; anyone can copy it and anyone can run it.
+What we charge for is the physical disk and the service of distribution.
+
+We charge two different prices depending on who is buying.  When a company or
+other organization buys the January 1997 Source CD-ROMs, we charge $240.
+When an individual buys the same CD-ROMs, we charge just $60.  This
+distinction is not a matter of who is allowed to use the software.  In either
+case, once you have a copy, you can distribute as many copies as you wish and
+there's no restriction on who can have or run them.  The price distinction is
+entirely a matter of what kind of entity pays for the CDs.
+
+You, the reader, are certainly an individual, not a company.  If you are
+buying a disk "in person", then you are probably doing so as an individual.
+But if you expect to be reimbursed by your employer, then the disk is really
+for the company; so please pay the company price and get reimbursed for it.
+We won't try to check up on you--we use the honor system--so please cooperate.
+
+Buying CDs at the company price is very helpful for GNU; just
+150 Source CDs at that price support an FSF programmer or tech writer for a
+year.
+
+ 
+
+Why Is There an Individual Price?
+.................................
+
+In the past, our distribution tapes were ordered mainly by companies.  The CD
+at the price of $240 provides them with all of our software for a much lower
+price than they would previously have paid for six different tapes.  To lower
+the price more would cut into the FSF's funds very badly and decrease the
+software development we can do.

+However, for individuals, $240 is too high a price; hardly anyone could
+afford that.  So we decided to make CDs available to individuals at the lower
+price of $60.
+
+ 
+
+Is There a Maximum Price?
+.........................
+
+Our stated prices are minimum prices.  Feel free to pay a higher price if you
+wish to support GNU development more.  The sky's the limit; we will accept as
+high a price as you can offer.  Or simply give a donation (tax-deductible in
+the U.S.) to the Free Software Foundation, a tax-exempt public charity.

+
+January 1997 Compiler Tools Binaries CD-ROM
+-------------------------------------------
+
+The fourth edition of our CD-ROM that has binaries and complete sources for
+GNU compiler tools for some systems which lack a compiler, will be available
+at the end of January 1997.  This enables the people who use these systems to
+compile GNU and other free software without having to buy a proprietary
+compiler.  You can also use these GNU tools to compile your own
+C/C++/Objective-C programs.  Older editions of this CD are available while
+supplies last at a reduced price; see the *note Free Software Foundation
+Order Form::.
+
+We hope to have more systems on each update of this CD.  If you can help
+build binaries for new systems (especially those that don't come with a C
+compiler), or have one to suggest, please contact us at the addresses on the
+top menu.
+
+These packages:
+
+        * DJGPP
+        * GCC/G++/Objective-C
+        * GNU C Library
+        * GDB
+        * Binutils
+        * Bison
+        * Emacs (MS-DOS only)
+        * Flex
+        * Make
+        * libg++
+
+On these platforms:
+
+        * `i386-msdos'
+        * `hppa1.1-hp-hpux9'
+        * `hppa1.1-hp-hpux10'
+        * `powerpc-ibm-aix4.2'
+        * `sparc-sun-solaris2.4'
+        * `sparc-sun-solaris2.5'
+        * `sparc-sun-sunos4.1'
+
+ 
+
+Source Code CD-ROMs
+-------------------
+
+We have several versions of our Source Code CD-ROMs available, including:
+
+   * *Note January 1997 Source Code CD-ROMs::, the newest release, has
+     programs, bug fixes, & improvements not on the other CDs.
+
+   * *Note July 1996 Source Code CD-ROMs::.
+
+   * December 1995 Source Code CD-ROMs, see the *note Free Software
+     Foundation Order Form::.
+
+   * June 1995 Source Code CD-ROM, see the *note Free Software Foundation
+     Order Form::.
+
+   * May 1994 Source Code CD-ROM, see the *note Free Software Foundation
+     Order Form::.
+
+   * November 1993 Source Code CD-ROM, see the *note Free Software Foundation
+     Order Form::.
+
+   * May 1993 Source Code CD-ROM, see the *note Free Software Foundation
+     Order Form::.
+
+   * October 1992 Source Code CD-ROM, see the *note Free Software Foundation
+     Order Form::.
+
+The older Source CDs are available while supplies last at a reduced price
+(please note that the December 1994 Source CD is permanently out of stock).
+All the Source CDs have Texinfo source for the GNU manuals listed in *Note
+Documentation::.
+
+MIT Scheme & much of X11 is *not* on the older Source CDs.
+
+There are no precompiled programs on these Source CDs.  You will need a C
+compiler (programs which need some other interpreter or compiler normally
+provide the C source for a bootstrapping program).  We ship C compiler
+binaries for some systems on the *Note Compiler Tools Binaries CD-ROM::.
+
+ 
+
+January 1997 Source Code CD-ROMs
+................................
+
+The 9th edition of our Source Code CD will be available at the end of January
+1997 with two CD-ROM disks.  It has programs, bug fixes, & improvements not
+on the older Source CDs.  It has these packages, & some manuals that are not
+part of packages.  The version number of each package listed might be higher
+on the 9th edition CD due to new releases being made between now and then.

+CD-ROM Subscription Service
+***************************
+
+Our subscription service enables you to stay current with the latest GNU
+developments.  For a one-time cost equivalent to three Source CD-ROMs (plus
+shipping in some cases), we will ship you four new versions of the *Note
+Source Code CD-ROMs::.  The CD-ROMs are sent as they are issued (currently
+twice a year, but we hope to make it more frequent).  We do not yet know if
+we will be offering subscriptions to the Compiler Tools Binaries CD.
+
+A subscription is an easy way to keep up with the regular bug fixes to the X
+Window System.  Each edition of the *Note Source Code CD-ROMs::, has updated
+sources for the X Window System.
+
+Please note: In two cases, you must pay 4 times the normal shipping required
+for a single order when you pay for each subscription.  If you're in Alaska,
+Hawaii, or Puerto Rico you must add $20.00 for shipping for each
+subscription.  If you're outside of the U.S., Canada, and Puerto Rico, you
+must add $80.00 for each subscription.  See "CD-ROMs" and "Tax and Shipping
+Costs" on the *note Free Software Foundation Order Form::.
+
+ 
+
+FSF T-shirt
+***********
+
+The front of our T-shirt has the GNU Emacs Lisp code `(USE 'GNU)' with "`()'"
+being the dancing parentheses from the cover of our `GNU Emacs Lisp Reference
+Manual' (drawn by Berkeley, CA artist Etienne Suvasa).  The shirt's back has
+the Preamble to the GNU General Public License.
+
+These shirts come in black, purple, red, pink, burgundy, blue, and natural
+(off-white).  When you order, please give 3 choices.  Black and purple are
+printed in white; the other colors are printed in black.  All shirts are
+thick 100% cotton, and come in sizes S, M, L, XL, and XXL (but they run small
+so you may want a larger size than usual).
+
+GNU T-shirts often create spontaneous friendships at conferences & on
+university campuses.  They also make great gifts for friends & family,
+including children!

+This directory contains the version 2.7.2 release of the GNU C
+compiler.  It includes all of the support for compiling C++ and
+Objective C, including a run-time library for Objective C.
+
+The GNU C compiler is free software.  See the file COPYING for copying
+permission.
+
+See the file gcc.texi (together with other files that it includes) for
+installation and porting information.  The file INSTALL contains a
+copy of the installation information, as plain ASCII.
+
+Installing this package will create various files in subdirectories of
+/usr/local/lib, which are passes used by the compiler and a library
+named libgcc.a.  It will also create /usr/local/bin/gcc, which is
+the user-level command to do a compilation.
+
+See the Bugs chapter of the GCC Manual for how to report bugs
+usefully.  An online readable version of the manual is in the files
+gcc.info*.
+
+The files pself.c and pself1.c are not part of GCC.
+They are programs that print themselves on standard output.
+They were written by Dario Dariol and Giovanni Cozzi, and are
+included for your hacking pleasure.  Likewise pself2.c
+(Who is the author of that?) and pself3.c (by Vlad Taeerov and Rashit

+The purpose of GCC pretesting is to verify that the new GCC
+distribution, about to be released, works properly on your system *with
+no change whatever*, when installed following the precise
+recommendations that come with the distribution.
+
+Here are some guidelines on how to do pretesting so as to make it
+helpful.  All of them follow from common sense together with the
+nature of the purpose and the situation.
+
+* It is absolutely vital that you mention even the smallest change or
+departure from the standard sources and installation procedure.
+
+Otherwise, you are not testing the same program that I wrote.  Testing
+a different program is usually of no use whatever.  It can even cause
+trouble if you fail to tell me that you tested some other program
+instead of what I know as GCC.  I might think that GCC works, when in
+fact it has not been properly tried, and might have a glaring fault.
+
+* Even changing the compilation options counts as a change in the
+program.  The GCC sources specify which compilation options to use.
+Some of them are specified in makefiles, and some in machine-specific
+configuration files.
+
+You have ways to override this--but if you do, then you are not
+testing what ordinary users will do.  Therefore, when pretesting, it
+is vital to test with the default compilation options.
+
+(It is okay to test with nonstandard options as well as testing with
+the standard ones.)
+
+* The machine and system configuration files of GCC are parts of
+GCC.  So when you test GCC, you need to do it with the
+configuration files that come with GCC.
+
+If GCC does not come with configuration files for a certain machine,
+and you test it with configuration files that don't come with GCC,
+this is effectively changing GCC.  Because the crucial fact about
+the planned release is that, without changes, it doesn't work on that
+machine.
+
+To make GCC work on that machine, I would need to install new
+configuration files.  That is not out of the question, since it is
+safe--it certainly won't break any other machines that already work.
+But you will have to rush me the legal papers to give the FSF
+permission to use a large piece of text.
+
+* Look for recommendations for your system.
+
+You can find these recommendations in the Installation node of the
+manual, and in the file INSTALL.  (These two files have the same text.)
+
+These files say which configuration name to use for your machine, so
+use the ones that are recommended.  If you guess, you might guess
+wrong and encounter spurious difficulties.  What's more, if you don't
+follow the recommendations then you aren't helping to test that its
+recommendations are valid.
+
+These files may describe other things that you need to do to make GCC
+work on your machine.  If so, you should follow these recommendations
+also, for the same reason.
+
+Also look at the Trouble chapter of the manual for items that
+pertain to your machine.
+
+* Don't delay sending information.
+
+When you find a problem, please double check it if you can do so
+quickly.  But don't spend a long time double-checking.  A good rule is
+always to tell me about every problem on the same day you encounter
+it, even if that means you can't find a solution before you report the
+problem.
+
+I'd much rather hear about a problem today and a solution tomorrow
+than get both of them tomorrow at the same time.
+
+* Make each bug report self-contained.
+
+If you refer back to another message, whether from you or from someone
+else, then it will be necessary for anyone who wants to investigate
+the bug to find the other message.  This may be difficult, it is
+probably time-consuming.
+
+To help me save time, simply copy the relevant parts of any previous
+messages into your own bug report.
+
+In particular, if I ask you for more information because a bug report
+was incomplete, it is best to send me the *entire* collection of
+relevant information, all together.  If you send just the additional
+information, that makes me do extra work.  There is even a risk that
+I won't remember what question you are sending me the answer to.
+
+* Always be precise when talking about changes you have made.  Show
+things rather than describing them.  Use exact filenames (relative to
+the main directory of the distribution), not partial ones.  For
+example, say "I changed Makefile" rather than "I changed the
+makefile".  Instead of saying "I defined the MUMBLE macro", send a
+diff that shows your change.
+
+* Always use `diff -c' to make diffs.  If you don't include context,
+it may be hard for me to figure out where you propose to make the
+changes.  I might have to ignore your patch because I can't tell what
+it means.
+
+* When you write a fix, keep in mind that I can't install a change
+that would break other systems.
+
+People often suggest fixing a problem by changing machine-independent
+files such as toplev.c to do something special that a particular
+system needs.  Sometimes it is totally obvious that such changes would
+break GCC for almost all users.  I can't possibly make a change like
+that.  All I can do is send it back to you and ask you to find a fix
+that is safe to install.
+
+Sometimes people send fixes that *might* be an improvement in
+general--but it is hard to be sure of this.  I can install such
+changes some of the time, but not during pretest, when I am trying to
+get a new version to work reliably as quickly as possible.
+
+The safest changes for me to install are changes to the configuration
+files for a particular machine.  At least I know those can't create
+bugs on other machines.
+
+* Don't try changing GCC unless it fails to work if you don't change it.
+
+* Don't even suggest changes that would only make GCC cleaner.
+Every change I install could introduce a bug, so I won't install
+a change unless I see it is necessary.
+
+* If you would like to suggest changes for purposes other than fixing
+serious bugs, don't wait till pretest time.  Instead, send them just
+after I make a release.  That's the best time for me to install them.
+
+* In some cases, if you don't follow these guidelines, your
+information might still be useful, but I might have to do more work to
+make use of it.  Unfortunately, I am so far behind in my work that I
+just can't get the job done unless you help me to do it efficiently.
+
+
+				Thank you

+
+Background: I have extensive experience with programming under Unix, in C
+in particular (since 1983), with standards and specifications for Internet
+protocols (since 1987), International Standards for character sets and
+encoding schemes (since 1988), ISO 8879 SGML (since 1990, national head of
+delegation to ISO/IEC JTC 1/SC 18/WG 8 since 1991), and ANSI X3.226 Common
+Lisp (since early 1994).  I have been an Emacs user and programmer from
+1984 to 1987 (TOPS-20) and from 1991 to present (Unix).  since early 1994,
+I have worked on GNU Emacs development, in both Lisp and C, and since mid
+1995, I have been tracking the development code.
+
+Services I offer the free software community include supporting Emacs users
+and programmers with expert advice (gratis on USENET or mailing lists where
+others may benefit), customizing and writing Emacs functions and packages,
+delivering courses and seminars from tutorials to writing Emacs Lisp and C
+extensions, and providing general aid with all GNU software.
+
+My standard rate is a flat USD 80 per hour or USD 2 per minute (you decide
+which time unit to apply), but to offset the cost of processing money, the
+minimum credit card charge is USD 100 and the minimum invoiced amount is
+USD 250.  Discounts are available to worthy causes -- present your case.
+Time away from home is billed at USD 40 per hour around the clock to
+encourage remote work.  (Courses and seminars are negotiated individually.)
+
+Please call only about actual work, I prefer mail for all other questions.

+This is a collection of things that test suites have
+said were "wrong" with GCC--but that I don't agree with.
+
+First, test suites sometimes test for compatibility with
+traditional C.  GCC with -traditional is not completely
+compatible with traditional C, and in some ways I think it
+should not be.
+
+* K&R C allowed \x to appear in a string literal (or character
+literal?)  even in cases where it is *not* followed by a sequence of
+hex digits.  I'm not convinced this is desirable.
+
+* K&R compilers allow comments to cross over an inclusion boundary (i.e.
+started in an include file and ended in the including file).
+I think this would be quite ugly and can't imagine it could
+be needed.
+
+Sometimes tests disagree with GCC's interpretation of the ANSI standard.
+
+* One test claims that this function should return 1.
+
+    enum {A, B} foo;
+
+    func (enum {B, A} arg)
+    {
+      return B;
+    }
+
+I think it should return 0, because the definition of B that
+applies is the one in func.
+
+* Some tests report failure when the compiler does not produce
+an error message for a certain program.
+
+ANSI C requires a "diagnostic" message for certain kinds of invalid
+programs, but a warning counts as a diagnostic.  If GCC produces
+a warning but not an error, that is correct ANSI support.
+When test suites call this "failure", the tests are broken.

+.SH DESCRIPTION
+The C preprocessor is a \c
+.I macro processor\c
+\& that is used automatically by
+the C compiler to transform your program before actual compilation.  It is
+called a macro processor because it allows you to define \c
+.I macros\c
+\&,
+which are brief abbreviations for longer constructs.
+
+The C preprocessor provides four separate facilities that you can use as
+you see fit:
+.TP
+\(bu
+Inclusion of header files.  These are files of declarations that can be
+substituted into your program.
+.TP
+\(bu
+Macro expansion.  You can define \c
+.I macros\c
+\&, which are abbreviations
+for arbitrary fragments of C code, and then the C preprocessor will
+replace the macros with their definitions throughout the program.
+.TP
+\(bu
+Conditional compilation.  Using special preprocessing directives, you
+can include or exclude parts of the program according to various
+conditions.
+.TP
+\(bu
+Line control.  If you use a program to combine or rearrange source files into
+an intermediate file which is then compiled, you can use line control
+to inform the compiler of where each source line originally came from.
+.PP
+C preprocessors vary in some details.  For a full explanation of the
+GNU C preprocessor, see the
+.B info
+file `\|\c
+.B cpp.info\c
+\&\|', or the manual
+.I The C Preprocessor\c
+\&.  Both of these are built from the same documentation source file, `\|\c
+.B cpp.texinfo\c
+\&\|'.  The GNU C
+preprocessor provides a superset of the features of ANSI Standard C.
+
+ANSI Standard C requires the rejection of many harmless constructs commonly
+used by today's C programs.  Such incompatibility would be inconvenient for
+users, so the GNU C preprocessor is configured to accept these constructs
+by default.  Strictly speaking, to get ANSI Standard C, you must use the
+options `\|\c
+.B \-trigraphs\c
+\&\|', `\|\c
+.B \-undef\c
+\&\|' and `\|\c
+.B \-pedantic\c
+\&\|', but in
+practice the consequences of having strict ANSI Standard C make it
+undesirable to do this.  
+
+Most often when you use the C preprocessor you will not have to invoke it
+explicitly: the C compiler will do so automatically.  However, the
+preprocessor is sometimes useful individually.
+
+When you call the preprocessor individually, either name
+(\c
+.B cpp\c
+\& or \c
+.B cccp\c
+\&) will do\(em\&they are completely synonymous.
+
+The C preprocessor expects two file names as arguments, \c
+.I infile\c
+\& and
+\c
+.I outfile\c
+\&.  The preprocessor reads \c
+.I infile\c
+\& together with any other
+files it specifies with `\|\c
+.B #include\c
+\&\|'.  All the output generated by the
+combined input files is written in \c
+.I outfile\c
+\&.
+
+Either \c
+.I infile\c
+\& or \c
+.I outfile\c
+\& may be `\|\c
+.B \-\c
+\&\|', which as \c
+.I infile\c
+\&
+means to read from standard input and as \c
+.I outfile\c
+\& means to write to
+standard output.  Also, if \c
+.I outfile\c
+\& or both file names are omitted,
+the standard output and standard input are used for the omitted file names.
+.SH OPTIONS
+Here is a table of command options accepted by the C preprocessor.  
+These options can also be given when compiling a C program; they are
+passed along automatically to the preprocessor when it is invoked by
+the compiler. 
+.TP
+.B \-P
+Inhibit generation of `\|\c
+.B #\c
+\&\|'-lines with line-number information in
+the output from the preprocessor.  This might be
+useful when running the preprocessor on something that is not C code
+and will be sent to a program which might be confused by the
+`\|\c
+.B #\c
+\&\|'-lines.
+.TP
+.B \-C
+Do not discard comments: pass them through to the output file.
+Comments appearing in arguments of a macro call will be copied to the
+output before the expansion of the macro call.
+.TP
+.B \-traditional
+Try to imitate the behavior of old-fashioned C, as opposed to ANSI C.
+.TP
+.B \-trigraphs
+Process ANSI standard trigraph sequences.  These are three-character
+sequences, all starting with `\|\c
+.B ??\c
+\&\|', that are defined by ANSI C to
+stand for single characters.  For example, `\|\c
+.B ??/\c
+\&\|' stands for
+`\|\c
+.BR "\e" "\|',"
+so `\|\c
+.B '??/n'\c
+\&\|' is a character constant for a newline.
+Strictly speaking, the GNU C preprocessor does not support all
+programs in ANSI Standard C unless `\|\c
+.B \-trigraphs\c
+\&\|' is used, but if
+you ever notice the difference it will be with relief.
+
+You don't want to know any more about trigraphs.
+.TP
+.B \-pedantic
+Issue warnings required by the ANSI C standard in certain cases such
+as when text other than a comment follows `\|\c
+.B #else\c
+\&\|' or `\|\c
+.B #endif\c
+\&\|'.
+.TP
+.B \-pedantic\-errors
+Like `\|\c
+.B \-pedantic\c
+\&\|', except that errors are produced rather than
+warnings.
+.TP
+.B \-Wtrigraphs
+Warn if any trigraphs are encountered (assuming they are enabled).
+.TP
+.B \-Wcomment
+.TP
+.B \-Wcomments
+Warn whenever a comment-start sequence `\|\c
+.B /*\c
+\&\|' appears in a comment.
+(Both forms have the same effect).
+.TP
+.B \-Wall
+Requests both `\|\c
+.B \-Wtrigraphs\c
+\&\|' and `\|\c
+.B \-Wcomment\c
+\&\|' (but not
+`\|\c
+.B \-Wtraditional\c
+\&\|'). 
+.TP
+.B \-Wtraditional
+Warn about certain constructs that behave differently in traditional and
+ANSI C.
+.TP
+.BI "\-I " directory\c
+\&
+Add the directory \c
+.I directory\c
+\& to the end of the list of
+directories to be searched for header files.
+This can be used to override a system header file, substituting your
+own version, since these directories are searched before the system
+header file directories.  If you use more than one `\|\c
+.B \-I\c
+\&\|' option,
+the directories are scanned in left-to-right order; the standard
+system directories come after.
+.TP
+.B \-I\-
+Any directories specified with `\|\c
+.B \-I\c
+\&\|' options before the `\|\c
+.B \-I\-\c
+\&\|'
+option are searched only for the case of `\|\c
+.B #include "\c
+.I file\c
+\&"\c
+\&\|';
+they are not searched for `\|\c
+.B #include <\c
+.I file\c
+\&>\c
+\&\|'.
+
+If additional directories are specified with `\|\c
+.B \-I\c
+\&\|' options after
+the `\|\c
+.B \-I\-\c
+\&\|', these directories are searched for all `\|\c
+.B #include\c
+\&\|'
+directives.
+
+In addition, the `\|\c
+.B \-I\-\c
+\&\|' option inhibits the use of the current
+directory as the first search directory for `\|\c
+.B #include "\c
+.I file\c
+\&"\c
+\&\|'.
+Therefore, the current directory is searched only if it is requested
+explicitly with `\|\c
+.B \-I.\c
+\&\|'.  Specifying both `\|\c
+.B \-I\-\c
+\&\|' and `\|\c
+.B \-I.\c
+\&\|'
+allows you to control precisely which directories are searched before
+the current one and which are searched after.
+.TP
+.B \-nostdinc
+Do not search the standard system directories for header files.
+Only the directories you have specified with `\|\c
+.B \-I\c
+\&\|' options
+(and the current directory, if appropriate) are searched.
+.TP
+.B \-nostdinc++
+Do not search for header files in the C++ specific standard
+directories, but do still search the other standard directories.
+(This option is used when building libg++.)
+.TP
+.BI "\-D " "name"\c
+\&
+Predefine \c
+.I name\c
+\& as a macro, with definition `\|\c
+.B 1\c
+\&\|'.
+.TP
+.BI "\-D " "name" = definition
+\&
+Predefine \c
+.I name\c
+\& as a macro, with definition \c
+.I definition\c
+\&.
+There are no restrictions on the contents of \c
+.I definition\c
+\&, but if
+you are invoking the preprocessor from a shell or shell-like program
+you may need to use the shell's quoting syntax to protect characters
+such as spaces that have a meaning in the shell syntax.  If you use more than
+one `\|\c
+.B \-D\c
+\&\|' for the same
+.I name\c
+\&, the rightmost definition takes effect.
+.TP
+.BI "\-U " "name"\c
+\&
+Do not predefine \c
+.I name\c
+\&.  If both `\|\c
+.B \-U\c
+\&\|' and `\|\c
+.B \-D\c
+\&\|' are
+specified for one name, the `\|\c
+.B \-U\c
+\&\|' beats the `\|\c
+.B \-D\c
+\&\|' and the name
+is not predefined.
+.TP
+.B \-undef
+Do not predefine any nonstandard macros.
+.TP
+.BI "\-A " "name(" value )
+Assert (in the same way as the \c
+.B #assert\c
+\& directive)
+the predicate \c
+.I name\c
+\& with tokenlist \c
+.I value\c
+\&.  Remember to escape or quote the parentheses on
+shell command lines.
+
+You can use `\|\c
+.B \-A-\c
+\&\|' to disable all predefined assertions; it also
+undefines all predefined macros.
+.TP
+.B \-dM
+Instead of outputting the result of preprocessing, output a list of
+`\|\c
+.B #define\c
+\&\|' directives for all the macros defined during the
+execution of the preprocessor, including predefined macros.  This gives
+you a way of finding out what is predefined in your version of the
+preprocessor; assuming you have no file `\|\c
+.B foo.h\c
+\&\|', the command
+.sp
+.br
+touch\ foo.h;\ cpp\ \-dM\ foo.h
+.br
+.sp
+will show the values of any predefined macros.
+.TP
+.B \-dD
+Like `\|\c
+.B \-dM\c
+\&\|' except in two respects: it does \c
+.I not\c
+\& include the
+predefined macros, and it outputs \c
+.I both\c
+\& the `\|\c
+.B #define\c
+\&\|'
+directives and the result of preprocessing.  Both kinds of output go to
+the standard output file.
+.PP
+.TP
+.BR \-M\  [ \-MG ]
+Instead of outputting the result of preprocessing, output a rule
+suitable for \c
+.B make\c
+\& describing the dependencies of the main
+source file.  The preprocessor outputs one \c
+.B make\c
+\& rule containing
+the object file name for that source file, a colon, and the names of
+all the included files.  If there are many included files then the
+rule is split into several lines using `\|\c
+.B \\\\\c
+\&\|'-newline.
+
+`\|\c
+.B \-MG\c
+\&\|' says to treat missing header files as generated files and assume \c
+they live in the same directory as the source file.  It must be specified \c
+in addition to `\|\c
+.B \-M\c
+\&\|'.
+
+This feature is used in automatic updating of makefiles.
+.TP
+.BR \-MM\  [ \-MG ]
+Like `\|\c
+.B \-M\c
+\&\|' but mention only the files included with `\|\c
+.B #include
+"\c
+.I file\c
+\&"\c
+\&\|'.  System header files included with `\|\c
+.B #include
+<\c
+.I file\c
+\&>\c
+\&\|' are omitted.
+.TP
+.BI \-MD\  file
+Like `\|\c
+.B \-M\c
+\&\|' but the dependency information is written to `\|\c
+.I file\c
+\&\|'.  This is in addition to compiling the file as
+specified\(em\&`\|\c
+.B \-MD\c
+\&\|' does not inhibit ordinary compilation the way
+`\|\c
+.B \-M\c
+\&\|' does.
+
+When invoking gcc, do not specify the `\|\c
+.I file\c
+\&\|' argument.  Gcc will create file names made by replacing `\|\c
+.B .c\c
+\&\|' with `\|\c
+.B .d\c
+\&\|' at the end of the input file names.
+
+In Mach, you can use the utility \c
+.B md\c
+\& to merge multiple files
+into a single dependency file suitable for using with the `\|\c
+.B make\c
+\&\|'
+command.
+.TP
+.BI \-MMD\  file
+Like `\|\c
+.B \-MD\c

+header files.

+activities.
+.TP
+.BI "\-imacros " "file"\c
+\&
+Process \c
+.I file\c
+\& as input, discarding the resulting output, before
+processing the regular input file.  Because the output generated from
+\c
+.I file\c
+\& is discarded, the only effect of `\|\c
+.B \-imacros \c
+.I file\c
+\&\c
+\&\|' is to
+make the macros defined in \c
+.I file\c
+\& available for use in the main
+input.  The preprocessor evaluates any `\|\c
+.B \-D\c
+\&\|' and `\|\c
+.B \-U\c
+\&\|' options
+on the command line before processing `\|\c
+.B \-imacros \c

+\&.
+.TP
+.BI "\-include " "file"

+.TP
+.BI "-idirafter " "dir"\c
+\&
+Add the directory \c

+\& to the second include path.  The directories
+on the second include path are searched when a header file is not found
+in any of the directories in the main include path (the one that
+`\|\c

+\&\|' adds to).
+.TP
+.BI "-iprefix " "prefix"\c

+options.
+.TP
+.BI "-iwithprefix " "dir"\c
+\&
+Add a directory to the second include path.  The directory's name is
+made by concatenating \c

+\&, where \c
+.I prefix\c

+was specified previously with `\|\c

+.TP
+.B \-lang-c
+.TP
+.B \-lang-c++
+.TP
+.B \-lang-objc
+.TP
+.B \-lang-objc++
+Specify the source language.  `\|\c
+.B \-lang-c++\c
+\&\|' makes the preprocessor
+handle C++ comment syntax, and includes extra default include
+directories for C++, and `\|\c
+.B \-lang-objc\c
+\&\|' enables the Objective C
+`\|\c
+.B #import\c
+\&\|' directive.  `\|\c
+.B \-lang-c\c
+\&\|' explicitly turns off both of
+these extensions, and `\|\c
+.B \-lang-objc++\c
+\&\|' enables both.
+
+These options are generated by the compiler driver \c
+.B gcc\c
+\&, but not
+passed from the `\|\c
+.B gcc\c
+\&\|' command line.
+.TP
+.B \-lint
+Look for commands to the program checker \c

+\& embedded in
+comments, and emit them preceded by `\|\c

+\&\|'.  For example,
+the comment `\|\c

+.B #pragma lint
+NOTREACHED\c
+\&\|'.
+
+This option is available only when you call \c

+\c
+.B gcc\c
+\& will not pass it from its command line.

+gcc, g++ \- GNU project C and C++ Compiler (v2.7)
+.SH SYNOPSIS
+.B gcc
+.RI "[ " option " | " filename " ].\|.\|."
+.br
+.B g++
+.RI "[ " option " | " filename " ].\|.\|."
+.SH WARNING
+The information in this man page is an extract from the full
+documentation of the GNU C compiler, and is limited to the meaning of
+the options.
+.PP
+This man page is not kept up to date except when volunteers want to
+maintain it.  If you find a discrepancy between the man page and the
+software, please check the Info file, which is the authoritative
+documentation.
+.PP
+If we find that the things in this man page that are out of date cause
+significant confusion or complaints, we will stop distributing the man
+page.  The alternative, updating the man page when we update the Info
+file, is impossible because the rest of the work of maintaining GNU CC
+leaves us no time for that.  The GNU project regards man pages as
+obsolete and should not let them take time away from other things.
+.PP
+For complete and current documentation, refer to the Info file `\|\c
+.B gcc\c
+\&\|' or the manual
+.I
+Using and Porting GNU CC (for version 2.0)\c
+\&.  Both are made from the Texinfo source file
+.BR gcc.texinfo .
+.SH DESCRIPTION
+The C and C++ compilers are integrated.  Both process input files
+through one or more of four stages: preprocessing, compilation,
+assembly, and linking.  Source filename suffixes identify the source
+language, but which name you use for the compiler governs default
+assumptions:
+.TP
+.B gcc
+assumes preprocessed (\c
+.B .i\c
+\&) files are C and assumes C style linking.
+.TP
+.B g++
+assumes preprocessed (\c
+.B .i\c
+\&) files are C++ and assumes C++ style linking.
+.PP
+Suffixes of source file names indicate the language and kind of
+processing to be done:
+.Sp
+.nf
+.ta \w'\fB.cxx\fP  'u
+\&\fB.c\fP	C source; preprocess, compile, assemble
+\&\fB.C\fP	C++ source; preprocess, compile, assemble
+\&\fB.cc\fP	C++ source; preprocess, compile, assemble
+\&\fB.cxx\fP	C++ source; preprocess, compile, assemble
+\&\fB.m\fP	Objective-C source; preprocess, compile, assemble
+\&\fB.i\fP	preprocessed C; compile, assemble
+\&\fB.ii\fP	preprocessed C++; compile, assemble
+\&\fB.s\fP	Assembler source; assemble
+\&\fB.S\fP	Assembler source; preprocess, assemble
+\&\fB.h\fP	Preprocessor file; not usually named on command line
+.Sp
+.fi
+Files with other suffixes are passed to the linker.  Common cases include:
+.Sp
+.nf
+\&\fB.o\fP	Object file
+\&\fB.a\fP	Archive file
+.br
+.fi
+.Sp
+Linking is always the last stage unless you use one of the
+.BR \-c ,
+.BR \-S ,
+or
+.B \-E
+options to avoid it (or unless compilation errors stop the whole
+process).  For the link stage, all
+.B .o
+files corresponding to source files,
+.B \-l
+libraries, unrecognized filenames (including named
+.B .o
+object files and
+.B .a
+archives)
+are passed to the linker in command-line order.
+.SH OPTIONS
+Options must be separate: `\|\c
+.B \-dr\c
+\&\|' is quite different from `\|\c
+.B \-d \-r
+\&\|'.
+.PP
+Most `\|\c
+.B \-f\c
+\&\|' and `\|\c
+.B \-W\c
+\&\|' options have two contrary forms:
+.BI \-f name
+and
+.BI \-fno\- name\c
+\& (or
+.BI \-W name
+and
+.BI \-Wno\- name\c
+\&).  Only the non-default forms are shown here.
+.PP
+Here is a summary of all the options, grouped by type.  Explanations are
+in the following sections.

+.SH OVERALL OPTIONS
+.TP
+.BI "\-x " "language"
+Specify explicitly the
+.I language\c
+\& for the following input files (rather than choosing a default based
+on the file name suffix) .  This option applies to all following input
+files until the next `\|\c
+.B \-x\c
+\&\|' option.  Possible values of \c
+.I language\c
+\& are
+`\|\c
+.B c\c
+\&\|', `\|\c
+.B objective\-c\c
+\&\|', `\|\c
+.B c\-header\c
+\&\|', `\|\c
+.B c++\c
+\&\|',
+`\|\c
+.B cpp\-output\c
+\&\|', `\|\c
+.B assembler\c
+\&\|', and `\|\c
+.B assembler\-with\-cpp\c
+\&\|'.
+.TP
+.B \-x none
+Turn off any specification of a language, so that subsequent files are
+handled according to their file name suffixes (as they are if `\|\c
+.B \-x\c
+\&\|'
+has not been used at all).
+.PP
+If you want only some of the four stages (preprocess, compile,
+assemble, link), you can use
+`\|\c
+.B \-x\c
+\&\|' (or filename suffixes) to tell \c
+.B gcc\c
+\& where to start, and
+one of the options `\|\c
+.B \-c\c
+\&\|', `\|\c
+.B \-S\c
+\&\|', or `\|\c
+.B \-E\c
+\&\|' to say where
+.B gcc\c
+\& is to stop.  Note that some combinations (for example,
+`\|\c
+.B \-x cpp\-output \-E\c
+\&\|') instruct \c
+.B gcc\c
+\& to do nothing at all.
+.TP
+.B \-c
+Compile or assemble the source files, but do not link.  The compiler
+output is an object file corresponding to each source file.
+.Sp
+By default, GCC makes the object file name for a source file by replacing
+the suffix `\|\c
+.B .c\c
+\&\|', `\|\c
+.B .i\c
+\&\|', `\|\c
+.B .s\c
+\&\|', etc., with `\|\c
+.B .o\c
+\&\|'.  Use
+.B \-o\c
+\& to select another name.
+.Sp
+GCC ignores any unrecognized input files (those that do not require
+compilation or assembly) with the
+.B \-c
+option.
+.TP
+.B \-S
+Stop after the stage of compilation proper; do not assemble.  The output
+is an assembler code file for each non-assembler input
+file specified.
+.Sp
+By default, GCC makes the assembler file name for a source file by
+replacing the suffix `\|\c
+.B .c\c
+\&\|', `\|\c
+.B .i\c
+\&\|', etc., with `\|\c
+.B .s\c
+\&\|'.  Use
+.B \-o\c
+\& to select another name.
+.Sp
+GCC ignores any input files that don't require compilation.
+.TP
+.B \-E
+Stop after the preprocessing stage; do not run the compiler proper.  The
+output is preprocessed source code, which is sent to the
+standard output.
+.Sp
+GCC ignores input files which don't require preprocessing.
+.TP
+.BI "\-o " file
+Place output in file \c
+.I file\c
+\&.  This applies regardless to whatever
+sort of output GCC is producing, whether it be an executable file,
+an object file, an assembler file or preprocessed C code.
+.Sp
+Since only one output file can be specified, it does not make sense to
+use `\|\c
+.B \-o\c
+\&\|' when compiling more than one input file, unless you are
+producing an executable file as output.
+.Sp
+If you do not specify `\|\c
+.B \-o\c
+\&\|', the default is to put an executable file
+in `\|\c
+.B a.out\c
+\&\|', the object file for `\|\c
+.I source\c
+.B \&.\c
+.I suffix\c
+\&\c
+\&\|' in
+`\|\c
+.I source\c
+.B \&.o\c
+\&\|', its assembler file in `\|\c
+.I source\c
+.B \&.s\c
+\&\|', and
+all preprocessed C source on standard output.
+.TP
+.B \-v
+Print (on standard error output) the commands executed to run the stages
+of compilation.  Also print the version number of the compiler driver
+program and of the preprocessor and the compiler proper.

+Use pipes rather than temporary files for communication between the
+various stages of compilation.  This fails to work on some systems where
+the assembler cannot read from a pipe; but the GNU assembler has
+no trouble.
+.PP
+.SH LANGUAGE OPTIONS
+The following options control the dialect of C that the compiler
+accepts:
+.TP
+.B \-ansi
+Support all ANSI standard C programs.
+.Sp
+This turns off certain features of GNU C that are incompatible with
+ANSI C, such as the \c
+.B asm\c
+\&, \c
+.B inline\c
+\& and \c
+.B typeof
+keywords, and predefined macros such as \c
+.B unix\c
+\& and \c
+.B vax
+that identify the type of system you are using.  It also enables the
+undesirable and rarely used ANSI trigraph feature, and disallows `\|\c
+.B $\c
+\&\|' as part of identifiers.
+.Sp
+The alternate keywords \c
+.B _\|_asm_\|_\c
+\&, \c
+.B _\|_extension_\|_\c
+\&,
+.B _\|_inline_\|_\c
+\& and \c
+.B _\|_typeof_\|_\c
+\& continue to work despite
+`\|\c
+.B \-ansi\c
+\&\|'.  You would not want to use them in an ANSI C program, of
+course, but it is useful to put them in header files that might be included
+in compilations done with `\|\c
+.B \-ansi\c
+\&\|'.  Alternate predefined macros
+such as \c
+.B _\|_unix_\|_\c
+\& and \c
+.B _\|_vax_\|_\c
+\& are also available, with or
+without `\|\c
+.B \-ansi\c
+\&\|'.
+.Sp
+The `\|\c
+.B \-ansi\c
+\&\|' option does not cause non-ANSI programs to be
+rejected gratuitously.  For that, `\|\c
+.B \-pedantic\c
+\&\|' is required in
+addition to `\|\c
+.B \-ansi\c
+\&\|'.
+.Sp
+The preprocessor predefines a macro \c
+.B _\|_STRICT_ANSI_\|_\c
+\& when you use the `\|\c
+.B \-ansi\c
+\&\|'
+option.  Some header files may notice this macro and refrain
+from declaring certain functions or defining certain macros that the
+ANSI standard doesn't call for; this is to avoid interfering with any
+programs that might use these names for other things.
+.TP
+.B \-fno\-asm
+Do not recognize \c
+.B asm\c
+\&, \c
+.B inline\c
+\& or \c
+.B typeof\c
+\& as a
+keyword.  These words may then be used as identifiers.  You can
+use \c
+.B _\|_asm_\|_\c
+\&, \c
+.B _\|_inline_\|_\c
+\& and \c
+.B _\|_typeof_\|_\c
+\& instead.
+`\|\c
+.B \-ansi\c
+\&\|' implies `\|\c
+.B \-fno\-asm\c
+\&\|'.
+.TP
+.B \-fno\-builtin
+Don't recognize built-in functions that do not begin with two leading
+underscores.  Currently, the functions affected include \c
+.B _exit\c
+\&,
+.B abort\c
+\&, \c
+.B abs\c
+\&, \c
+.B alloca\c
+\&, \c
+.B cos\c
+\&, \c
+.B exit\c
+\&,
+.B fabs\c
+\&, \c
+.B labs\c
+\&, \c
+.B memcmp\c
+\&, \c
+.B memcpy\c
+\&, \c
+.B sin\c
+\&,
+.B sqrt\c
+\&, \c
+.B strcmp\c
+\&, \c
+.B strcpy\c
+\&, and \c
+.B strlen\c
+\&.
+.Sp
+The `\|\c
+.B \-ansi\c
+\&\|' option prevents \c
+.B alloca\c
+\& and \c
+.B _exit\c
+\& from
+being builtin functions.
+.TP
+.B \-fhosted
+Compile for a hosted environment; this implies the `\|\c
+.B \-fbuiltin\c
+\&\|' option, and implies that suspicious declarations of
+.B main\c
+\& should be warned about.
+.TP
+.B \-ffreestanding
+Compile for a freestanding environment; this implies the `\|\c
+.B \-fno-builtin\c
+\&\|' option, and implies that
+.B main\c
+\& has no special requirements.
+.TP
+.B \-fno\-strict\-prototype
+Treat a function declaration with no arguments, such as `\|\c
+.B int foo
+();\c
+\&\|', as C would treat it\(em\&as saying nothing about the number of
+arguments or their types (C++ only).  Normally, such a declaration in
+C++ means that the function \c
+.B foo\c
+\& takes no arguments.
+.TP
+.B \-trigraphs
+Support ANSI C trigraphs.  The `\|\c
+.B \-ansi\c
+\&\|' option implies `\|\c
+.B \-trigraphs\c
+\&\|'.
+.TP
+.B \-traditional
+Attempt to support some aspects of traditional C compilers.
+For details, see the GNU C Manual; the duplicate list here
+has been deleted so that we won't get complaints when it
+is out of date.
+.Sp
+But one note about C++ programs only (not C).  `\|\c
+.B \-traditional\c
+\&\|' has one additional effect for C++: assignment to
+.B this
+is permitted.  This is the same as the effect of `\|\c
+.B \-fthis\-is\-variable\c
+\&\|'.
+.TP
+.B \-traditional\-cpp
+Attempt to support some aspects of traditional C preprocessors.
+This includes the items that specifically mention the preprocessor above,
+but none of the other effects of `\|\c
+.B \-traditional\c
+\&\|'.
+.TP
+.B \-fdollars\-in\-identifiers
+Permit the use of `\|\c
+.B $\c
+\&\|' in identifiers (C++ only).  You can also use
+`\|\c
+.B \-fno\-dollars\-in\-identifiers\c
+\&\|' to explicitly prohibit use of
+`\|\c
+.B $\c
+\&\|'.  (GNU C++ allows `\|\c
+.B $\c
+\&\|' by default on some target systems
+but not others.)
+.TP
+.B \-fenum\-int\-equiv
+Permit implicit conversion of \c
+.B int\c
+\& to enumeration types (C++
+only).  Normally GNU C++ allows conversion of \c
+.B enum\c
+\& to \c
+.B int\c
+\&,
+but not the other way around.
+.TP
+.B \-fexternal\-templates
+Produce smaller code for template declarations, by generating only a
+single copy of each template function where it is defined (C++ only).
+To use this option successfully, you must also mark all files that
+use templates with either `\|\c
+.B #pragma implementation\c
+\&\|' (the definition) or
+`\|\c
+.B #pragma interface\c
+\&\|' (declarations).
+
+When your code is compiled with `\|\c
+.B \-fexternal\-templates\c
+\&\|', all
+template instantiations are external.  You must arrange for all
+necessary instantiations to appear in the implementation file; you can
+do this with a \c
+.B typedef\c
+\& that references each instantiation needed.
+Conversely, when you compile using the default option
+`\|\c
+.B \-fno\-external\-templates\c
+\&\|', all template instantiations are
+explicitly internal.
+.TP
+.B \-fall\-virtual
+Treat all possible member functions as virtual, implicitly.  All
+member functions (except for constructor functions and
+.B new
+or
+.B delete
+member operators) are treated as virtual functions of the class where
+they appear.
+.Sp
+This does not mean that all calls to these member functions will be
+made through the internal table of virtual functions.  Under some
+circumstances, the compiler can determine that a call to a given
+virtual function can be made directly; in these cases the calls are
+direct in any case.
+.TP
+.B \-fcond\-mismatch
+Allow conditional expressions with mismatched types in the second and
+third arguments.  The value of such an expression is void.
+.TP
+.B \-fthis\-is\-variable
+Permit assignment to \c
+.B this\c
+\& (C++ only).  The incorporation of
+user-defined free store management into C++ has made assignment to
+`\|\c
+.B this\c
+\&\|' an anachronism.  Therefore, by default it is invalid to
+assign to \c
+.B this\c
+\& within a class member function.  However, for
+backwards compatibility, you can make it valid with
+`\|\c
+.B \-fthis-is-variable\c
+\&\|'.
+.TP
+.B \-funsigned\-char
+Let the type \c
+.B char\c
+\& be unsigned, like \c
+.B unsigned char\c
+\&.
+.Sp
+Each kind of machine has a default for what \c
+.B char\c
+\& should
+be.  It is either like \c
+.B unsigned char\c
+\& by default or like
+.B signed char\c
+\& by default.
+.Sp
+Ideally, a portable program should always use \c
+.B signed char\c
+\& or
+.B unsigned char\c
+\& when it depends on the signedness of an object.
+But many programs have been written to use plain \c
+.B char\c
+\& and
+expect it to be signed, or expect it to be unsigned, depending on the
+machines they were written for.  This option, and its inverse, let you
+make such a program work with the opposite default.
+.Sp
+The type \c
+.B char\c
+\& is always a distinct type from each of
+.B signed char\c
+\& and \c
+.B unsigned char\c
+\&, even though its behavior
+is always just like one of those two.
+.TP
+.B \-fsigned\-char
+Let the type \c
+.B char\c
+\& be signed, like \c
+.B signed char\c
+\&.
+.Sp
+Note that this is equivalent to `\|\c
+.B \-fno\-unsigned\-char\c
+\&\|', which is
+the negative form of `\|\c
+.B \-funsigned\-char\c
+\&\|'.  Likewise,
+`\|\c
+.B \-fno\-signed\-char\c
+\&\|' is equivalent to `\|\c
+.B \-funsigned\-char\c
+\&\|'.
+.TP
+.B \-fsigned\-bitfields
+.TP
+.B \-funsigned\-bitfields
+.TP
+.B \-fno\-signed\-bitfields
+.TP
+.B \-fno\-unsigned\-bitfields
+These options control whether a bitfield is
+signed or unsigned, when declared with no explicit `\|\c
+.B signed\c
+\&\|' or `\|\c
+.B unsigned\c
+\&\|' qualifier.  By default, such a bitfield is
+signed, because this is consistent: the basic integer types such as
+.B int\c
+\& are signed types.
+.Sp
+However, when you specify `\|\c
+.B \-traditional\c
+\&\|', bitfields are all unsigned
+no matter what.
+.TP
+.B \-fwritable\-strings
+Store string constants in the writable data segment and don't uniquize
+them.  This is for compatibility with old programs which assume they
+can write into string constants.  `\|\c
+.B \-traditional\c
+\&\|' also has this
+effect.
+.Sp
+Writing into string constants is a very bad idea; \*(lqconstants\*(rq should
+be constant.
+.SH PREPROCESSOR OPTIONS
+These options control the C preprocessor, which is run on each C source
+file before actual compilation.
+.PP
+If you use the `\|\c
+.B \-E\c
+\&\|' option, GCC does nothing except preprocessing.
+Some of these options make sense only together with `\|\c
+.B \-E\c
+\&\|' because
+they cause the preprocessor output to be unsuitable for actual
+compilation.
+.TP
+.BI "\-include " "file"
+Process \c
+.I file\c
+\& as input before processing the regular input file.
+In effect, the contents of \c
+.I file\c
+\& are compiled first.  Any `\|\c
+.B \-D\c
+\&\|'
+and `\|\c
+.B \-U\c
+\&\|' options on the command line are always processed before
+`\|\c
+.B \-include \c
+.I file\c
+\&\c
+\&\|', regardless of the order in which they are
+written.  All the `\|\c
+.B \-include\c
+\&\|' and `\|\c
+.B \-imacros\c
+\&\|' options are
+processed in the order in which they are written.
+.TP
+.BI "\-imacros " file
+Process \c
+.I file\c
+\& as input, discarding the resulting output, before
+processing the regular input file.  Because the output generated from
+.I file\c
+\& is discarded, the only effect of `\|\c
+.B \-imacros \c
+.I file\c
+\&\c
+\&\|' is to
+make the macros defined in \c
+.I file\c
+\& available for use in the main
+input.  The preprocessor evaluates any `\|\c
+.B \-D\c
+\&\|' and `\|\c
+.B \-U\c
+\&\|' options
+on the command line before processing `\|\c
+.B \-imacros\c
+.I file\c
+\&\|', regardless of the order in
+which they are written.  All the `\|\c
+.B \-include\c
+\&\|' and `\|\c
+.B \-imacros\c
+\&\|'
+options are processed in the order in which they are written.
+.TP
+.BI "\-idirafter " "dir"
+Add the directory \c
+.I dir\c
+\& to the second include path.  The directories
+on the second include path are searched when a header file is not found
+in any of the directories in the main include path (the one that
+`\|\c
+.B \-I\c
+\&\|' adds to).
+.TP
+.BI "\-iprefix " "prefix"
+Specify \c
+.I prefix\c
+\& as the prefix for subsequent `\|\c
+.B \-iwithprefix\c
+\&\|'
+options.
+.TP
+.BI "\-iwithprefix " "dir"
+Add a directory to the second include path.  The directory's name is
+made by concatenating \c
+.I prefix\c
+\& and \c
+.I dir\c
+\&, where \c
+.I prefix
+was specified previously with `\|\c
+.B \-iprefix\c
+\&\|'.
+.TP
+.B \-nostdinc
+Do not search the standard system directories for header files.  Only
+the directories you have specified with `\|\c
+.B \-I\c
+\&\|' options (and the
+current directory, if appropriate) are searched.
+.Sp
+By using both `\|\c
+.B \-nostdinc\c
+\&\|' and `\|\c
+.B \-I\-\c
+\&\|', you can limit the include-file search file to only those
+directories you specify explicitly.
+.TP
+.B \-nostdinc++
+Do not search for header files in the C++\-specific standard directories,
+but do still search the other standard directories.
+(This option is used when building `\|\c
+.B libg++\c
+\&\|'.)
+.TP
+.B \-undef
+Do not predefine any nonstandard macros.  (Including architecture flags).
+.TP
+.B \-E
+Run only the C preprocessor.  Preprocess all the C source files
+specified and output the results to standard output or to the

+.TP
+.B \-C
+Tell the preprocessor not to discard comments.  Used with the

+Used with the `\|\c
+.B \-E\c

+.TP
+.B \-M\  [ \-MG ]
+Tell the preprocessor to output a rule suitable for \c
+.B make
+describing the dependencies of each object file.  For each source file,
+the preprocessor outputs one \c
+.B make\c
+\&-rule whose target is the object
+file name for that source file and whose dependencies are all the files
+`\|\c
+.B #include\c
+\&\|'d in it.  This rule may be a single line or may be
+continued with `\|\c
+.B \e\c
+\&\|'-newline if it is long.  The list of rules is
+printed on standard output instead of the preprocessed C program.
+.Sp
+`\|\c
+.B \-M\c
+\&\|' implies `\|\c
+.B \-E\c
+\&\|'.
+.Sp
+`\|\c
+.B \-MG\c

+they live in the same directory as the source file.  It must be specified \c
+in addition to `\|\c

+\&\|'.
+.TP
+.B \-MM\  [ \-MG ]
+Like `\|\c

+.TP
+.B \-MD
+Like `\|\c
+.B \-M\c

+names made by replacing `\|\c
+.B .o\c
+\&\|' with `\|\c
+.B .d\c
+\&\|' at the end of the
+output file names.  This is in addition to compiling the file as
+specified\(em\&`\|\c
+.B \-MD\c
+\&\|' does not inhibit ordinary compilation the way
+`\|\c
+.B \-M\c
+\&\|' does.
+.Sp
+The Mach utility `\|\c
+.B md\c
+\&\|' can be used to merge the `\|\c
+.B .d\c

+into a single dependency file suitable for using with the `\|\c
+.B make\c

+command.
+.TP
+.B \-MMD
+Like `\|\c

+.TP
+.B \-dD
+Tell the preprocessor to pass all macro definitions into the output, in

+.SH ASSEMBLER OPTION
+.TP
+.BI "\-Wa," "option"
+Pass \c
+.I option\c
+\& as an option to the assembler.  If \c
+.I option
+contains commas, it is split into multiple options at the commas.
+.SH LINKER OPTIONS
+These options come into play when the compiler links object files into
+an executable output file.  They are meaningless if the compiler is
+not doing a link step.
+.TP
+.I object-file-name
+A file name that does not end in a special recognized suffix is
+considered to name an object file or library.  (Object files are
+distinguished from libraries by the linker according to the file
+contents.)  If GCC does a link step, these object files are used as input
+to the linker.
+.TP
+.BI \-l library
+Use the library named \c
+.I library\c
+\& when linking.
+.Sp
+The linker searches a standard list of directories for the library,
+which is actually a file named `\|\c
+.B lib\c
+.I library\c
+\&.a\c
+\&\|'.  The linker
+then uses this file as if it had been specified precisely by name.
+.Sp
+The directories searched include several standard system directories
+plus any that you specify with `\|\c
+.B \-L\c
+\&\|'.
+.Sp
+Normally the files found this way are library files\(em\&archive files
+whose members are object files.  The linker handles an archive file by
+scanning through it for members which define symbols that have so far
+been referenced but not defined.  However, if the linker finds an
+ordinary object file rather than a library, the object file is linked
+in the usual fashion.  The only difference between using an `\|\c
+.B \-l\c
+\&\|' option and specifying a file
+name is that `\|\c
+.B \-l\c
+\&\|' surrounds
+.I library
+with `\|\c
+.B lib\c
+\&\|' and `\|\c
+.B .a\c
+\&\|' and searches several directories.
+.TP
+.B \-lobjc
+You need this special case of the
+.B \-l
+option in order to link an Objective C program.
+.TP
+.B \-nostartfiles
+Do not use the standard system startup files when linking.
+The standard libraries are used normally.
+.TP
+.B \-nostdlib
+Don't use the standard system libraries and startup files when linking.
+Only the files you specify will be passed to the linker.
+.TP
+.B \-static
+On systems that support dynamic linking, this prevents linking with the shared
+libraries.  On other systems, this option has no effect.
+.TP
+.B \-shared
+Produce a shared object which can then be linked with other objects to
+form an executable.  Only a few systems support this option.
+.TP
+.B \-symbolic
+Bind references to global symbols when building a shared object.  Warn
+about any unresolved references (unless overridden by the link editor
+option `\|\c
+.B
+\-Xlinker \-z \-Xlinker defs\c
+\&\|').  Only a few systems support
+this option.
+.TP
+.BI "\-Xlinker " "option"
+Pass \c
+.I option
+as an option to the linker.  You can use this to
+supply system-specific linker options which GNU CC does not know how to
+recognize.
+.Sp
+If you want to pass an option that takes an argument, you must use
+`\|\c
+.B \-Xlinker\c
+\&\|' twice, once for the option and once for the argument.
+For example, to pass `\|\c
+.B
+\-assert definitions\c
+\&\|', you must write
+`\|\c
+.B
+\-Xlinker \-assert \-Xlinker definitions\c
+\&\|'.  It does not work to write
+`\|\c
+.B
+\-Xlinker "\-assert definitions"\c
+\&\|', because this passes the entire
+string as a single argument, which is not what the linker expects.
+.TP
+.BI "\-Wl," "option"
+Pass \c

+commas, it is split into multiple options at the commas.
+.TP
+.BI "\-u " "symbol"
+Pretend the symbol
+.I symbol
+is undefined, to force linking of

+different symbols to force loading of additional library modules.
+.SH DIRECTORY OPTIONS
+These options specify directories to search for header files, for
+libraries and for parts of the compiler:
+.TP
+.BI "\-I" "dir"
+Append directory \c
+.I dir\c
+\& to the list of directories searched for include files.
+.TP
+.B \-I\-
+Any directories you specify with `\|\c

+.B \-I\-\c
+\&\|'
+option are searched only for the case of `\|\c
+.B

+.Sp
+If additional directories are specified with `\|\c

+.B #include\c
+\&\|'
+directives.  (Ordinarily \c
+.I all\c
+\& `\|\c
+.B \-I\c
+\&\|' directories are used
+this way.)
+.Sp
+In addition, the `\|\c
+.B \-I\-\c
+\&\|' option inhibits the use of the current
+directory (where the current input file came from) as the first search
+directory for `\|\c
+.B
+#include "\c
+.I file\c
+.B
+\&"\c
+\&\|'.  There is no way to
+override this effect of `\|\c
+.B \-I\-\c
+\&\|'.  With `\|\c
+.B \-I.\c
+\&\|' you can specify
+searching the directory which was current when the compiler was
+invoked.  That is not exactly the same as what the preprocessor does
+by default, but it is often satisfactory.
+.Sp
+`\|\c
+.B \-I\-\c

+This option specifies where to find the executables, libraries and
+data files of the compiler itself.
+.Sp
+The compiler driver program runs one or more of the subprograms
+`\|\c
+.B cpp\c
+\&\|', `\|\c
+.B cc1\c
+\&\|' (or, for C++, `\|\c
+.B cc1plus\c
+\&\|'), `\|\c
+.B as\c
+\&\|' and `\|\c
+.B ld\c
+\&\|'.  It tries
+.I prefix\c
+\& as a prefix for each program it tries to run, both with and
+without `\|\c
+.I machine\c
+.B /\c
+.I version\c
+.B /\c
+\&\|'.
+.Sp
+For each subprogram to be run, the compiler driver first tries the
+`\|\c
+.B \-B\c
+\&\|' prefix, if any.  If that name is not found, or if `\|\c
+.B \-B\c
+\&\|'
+was not specified, the driver tries two standard prefixes, which are
+`\|\c
+.B /usr/lib/gcc/\c
+\&\|' and `\|\c
+.B /usr/local/lib/gcc-lib/\c
+\&\|'.  If neither of
+those results in a file name that is found, the compiler driver
+searches for the unmodified program
+name, using the directories specified in your
+`\|\c
+.B PATH\c
+\&\|' environment variable.
+.Sp
+The run-time support file `\|\c
+.B libgcc.a\c
+\&\|' is also searched for using the
+`\|\c
+.B \-B\c
+\&\|' prefix, if needed.  If it is not found there, the two
+standard prefixes above are tried, and that is all.  The file is left
+out of the link if it is not found by those means.  Most of the time,
+on most machines, `\|\c
+.B libgcc.a\c
+\&\|' is not actually necessary.
+.Sp
+You can get a similar result from the environment variable
+.B GCC_EXEC_PREFIX\c
+\&; if it is defined, its value is used as a prefix
+in the same way.  If both the `\|\c
+.B \-B\c
+\&\|' option and the
+.B GCC_EXEC_PREFIX\c
+\& variable are present, the `\|\c
+.B \-B\c
+\&\|' option is
+used first and the environment variable value second.
+.SH WARNING OPTIONS
+Warnings are diagnostic messages that report constructions which
+are not inherently erroneous but which are risky or suggest there
+may have been an error.
+.Sp
+These options control the amount and kinds of warnings produced by GNU
+CC:
+.TP
+.B \-fsyntax\-only
+Check the code for syntax errors, but don't emit any output.
+.TP
+.B \-w
+Inhibit all warning messages.
+.TP
+.B \-Wno\-import
+Inhibit warning messages about the use of
+.BR #import .
+.TP
+.B \-pedantic
+Issue all the warnings demanded by strict ANSI standard C; reject
+all programs that use forbidden extensions.
+.Sp
+Valid ANSI standard C programs should compile properly with or without
+this option (though a rare few will require `\|\c
+.B \-ansi\c
+\&\|').  However,
+without this option, certain GNU extensions and traditional C features
+are supported as well.  With this option, they are rejected.  There is
+no reason to \c
+.I use\c
+\& this option; it exists only to satisfy pedants.
+.Sp
+`\|\c
+.B \-pedantic\c
+\&\|' does not cause warning messages for use of the
+alternate keywords whose names begin and end with `\|\c
+.B _\|_\c
+\&\|'.  Pedantic
+warnings are also disabled in the expression that follows
+.B _\|_extension_\|_\c
+\&.  However, only system header files should use
+these escape routes; application programs should avoid them.
+.TP
+.B \-pedantic\-errors
+Like `\|\c
+.B \-pedantic\c
+\&\|', except that errors are produced rather than
+warnings.
+.TP
+.B \-W
+Print extra warning messages for these events:
+.TP
+\ \ \ \(bu
+A nonvolatile automatic variable might be changed by a call to
+.B longjmp\c
+\&.  These warnings are possible only in
+optimizing compilation.
+.Sp
+The compiler sees only the calls to \c
+.B setjmp\c
+\&.  It cannot know
+where \c
+.B longjmp\c
+\& will be called; in fact, a signal handler could
+call it at any point in the code.  As a result, you may get a warning
+even when there is in fact no problem because \c
+.B longjmp\c
+\& cannot
+in fact be called at the place which would cause a problem.
+.TP
+\ \ \ \(bu
+A function can return either with or without a value.  (Falling
+off the end of the function body is considered returning without
+a value.)  For example, this function would evoke such a
+warning:
+.Sp
+.nf
+foo (a)
+{
+  if (a > 0)
+    return a;
+}
+.Sp
+.fi
+Spurious warnings can occur because GNU CC does not realize that
+certain functions (including \c
+.B abort\c
+\& and \c
+.B longjmp\c
+\&)
+will never return.
+.TP
+\ \ \ \(bu
+An expression-statement or the left-hand side of a comma expression
+contains no side effects. 
+To suppress the warning, cast the unused expression to void.
+For example, an expression such as `\|\c
+.B x[i,j]\c
+\&\|' will cause a warning,
+but `\|\c
+.B x[(void)i,j]\c
+\&\|' will not.
+.TP
+\ \ \ \(bu
+An unsigned value is compared against zero with `\|\c
+.B >\c
+\&\|' or `\|\c
+.B <=\c
+\&\|'.
+.PP
+.TP
+.B \-Wimplicit
+Warn whenever a function or parameter is implicitly declared.
+.TP
+.B \-Wmain
+Warn if the
+.B main
+function is declared or defined with a suspicious type.
+Typically, it is a function with external linkage, returning
+.B int\c
+\&, and
+taking zero or two arguments.
+
+.TP
+.B \-Wreturn\-type
+Warn whenever a function is defined with a return-type that defaults
+to \c
+.B int\c
+\&.  Also warn about any \c
+.B return\c
+\& statement with no
+return-value in a function whose return-type is not \c
+.B void\c
+\&.
+.TP
+.B \-Wunused
+Warn whenever a local variable is unused aside from its declaration,
+whenever a function is declared static but never defined, and whenever
+a statement computes a result that is explicitly not used.
+.TP
+.B \-Wswitch
+Warn whenever a \c
+.B switch\c
+\& statement has an index of enumeral type
+and lacks a \c
+.B case\c
+\& for one or more of the named codes of that
+enumeration.  (The presence of a \c
+.B default\c
+\& label prevents this
+warning.)  \c
+.B case\c
+\& labels outside the enumeration range also
+provoke warnings when this option is used.
+.TP
+.B \-Wcomment
+Warn whenever a comment-start sequence `\|\c
+.B /\(**\c
+\&\|' appears in a comment.
+.TP
+.B \-Wtrigraphs
+Warn if any trigraphs are encountered (assuming they are enabled).
+.TP
+.B \-Wformat
+Check calls to \c
+.B printf\c
+\& and \c
+.B scanf\c
+\&, etc., to make sure that
+the arguments supplied have types appropriate to the format string
+specified.
+.TP
+.B \-Wchar\-subscripts
+Warn if an array subscript has type
+.BR char .
+This is a common cause of error, as programmers often forget that this
+type is signed on some machines.
+.TP
+.B \-Wuninitialized
+An automatic variable is used without first being initialized.
+.Sp
+These warnings are possible only in optimizing compilation,
+because they require data flow information that is computed only
+when optimizing.  If you don't specify `\|\c
+.B \-O\c
+\&\|', you simply won't
+get these warnings.
+.Sp
+These warnings occur only for variables that are candidates for
+register allocation.  Therefore, they do not occur for a variable that
+is declared \c
+.B volatile\c
+\&, or whose address is taken, or whose size
+is other than 1, 2, 4 or 8 bytes.  Also, they do not occur for
+structures, unions or arrays, even when they are in registers.
+.Sp
+Note that there may be no warning about a variable that is used only
+to compute a value that itself is never used, because such
+computations may be deleted by data flow analysis before the warnings
+are printed.
+.Sp
+These warnings are made optional because GNU CC is not smart
+enough to see all the reasons why the code might be correct
+despite appearing to have an error.  Here is one example of how
+this can happen:
+.Sp
+.nf
+{
+  int x;
+  switch (y)
+    {
+    case 1: x = 1;
+      break;
+    case 2: x = 4;
+      break;
+    case 3: x = 5;
+    }
+  foo (x);
+}
+.Sp
+.fi
+If the value of \c
+.B y\c
+\& is always 1, 2 or 3, then \c
+.B x\c
+\& is
+always initialized, but GNU CC doesn't know this.  Here is
+another common case:
+.Sp
+.nf
+{
+  int save_y;
+  if (change_y) save_y = y, y = new_y;
+  .\|.\|.
+  if (change_y) y = save_y;
+}
+.Sp
+.fi
+This has no bug because \c
+.B save_y\c
+\& is used only if it is set.
+.Sp
+Some spurious warnings can be avoided if you declare as
+.B volatile\c
+\& all the functions you use that never return.
+.TP
+.B \-Wparentheses
+Warn if parentheses are omitted in certain contexts.
+.TP
+.B \-Wtemplate\-debugging
+When using templates in a C++ program, warn if debugging is not yet
+fully available (C++ only).
+.TP
+.B \-Wall
+All of the above `\|\c
+.B \-W\c
+\&\|' options combined.  These are all the
+options which pertain to usage that we recommend avoiding and that we
+believe is easy to avoid, even in conjunction with macros.
+.PP
+The remaining `\|\c
+.B \-W.\|.\|.\c
+\&\|' options are not implied by `\|\c
+.B \-Wall\c
+\&\|'
+because they warn about constructions that we consider reasonable to
+use, on occasion, in clean programs.
+.TP
+.B \-Wtraditional
+Warn about certain constructs that behave differently in traditional and
+ANSI C.
+.TP
+\ \ \ \(bu
+Macro arguments occurring within string constants in the macro body.
+These would substitute the argument in traditional C, but are part of
+the constant in ANSI C.
+.TP
+\ \ \ \(bu
+A function declared external in one block and then used after the end of
+the block.
+.TP
+\ \ \ \(bu
+A \c
+.B switch\c
+\& statement has an operand of type \c
+.B long\c
+\&.
+.PP
+.TP
+.B \-Wshadow
+Warn whenever a local variable shadows another local variable.
+.TP
+.BI "\-Wid\-clash\-" "len"
+Warn whenever two distinct identifiers match in the first \c
+.I len
+characters.  This may help you prepare a program that will compile
+with certain obsolete, brain-damaged compilers.
+.TP
+.B \-Wpointer\-arith
+Warn about anything that depends on the \*(lqsize of\*(rq a function type or
+of \c
+.B void\c
+\&.  GNU C assigns these types a size of 1, for
+convenience in calculations with \c
+.B void \(**\c
+\& pointers and pointers
+to functions.
+.TP
+.B \-Wcast\-qual
+Warn whenever a pointer is cast so as to remove a type qualifier from
+the target type.  For example, warn if a \c
+.B const char \(**\c
+\& is cast
+to an ordinary \c
+.B char \(**\c
+\&.
+.TP
+.B \-Wcast\-align
+Warn whenever a pointer is cast such that the required alignment of the
+target is increased.  For example, warn if a \c
+.B char \(**\c
+\& is cast to
+an \c
+.B int \(**\c
+\& on machines where integers can only be accessed at
+two- or four-byte boundaries.
+.TP
+.B \-Wwrite\-strings
+Give string constants the type \c
+.B const char[\c
+.I length\c
+.B ]\c
+\& so that
+copying the address of one into a non-\c
+.B const\c
+\& \c
+.B char \(**
+pointer will get a warning.  These warnings will help you find at
+compile time code that can try to write into a string constant, but
+only if you have been very careful about using \c
+.B const\c
+\& in
+declarations and prototypes.  Otherwise, it will just be a nuisance;
+this is why we did not make `\|\c
+.B \-Wall\c
+\&\|' request these warnings.
+.TP
+.B \-Wconversion
+Warn if a prototype causes a type conversion that is different from what
+would happen to the same argument in the absence of a prototype.  This
+includes conversions of fixed point to floating and vice versa, and
+conversions changing the width or signedness of a fixed point argument
+except when the same as the default promotion.
+.TP
+.B \-Waggregate\-return
+Warn if any functions that return structures or unions are defined or
+called.  (In languages where you can return an array, this also elicits
+a warning.)
+.TP
+.B \-Wstrict\-prototypes
+Warn if a function is declared or defined without specifying the
+argument types.  (An old-style function definition is permitted without
+a warning if preceded by a declaration which specifies the argument
+types.)
+.TP
+.B \-Wmissing\-prototypes
+Warn if a global function is defined without a previous prototype
+declaration.  This warning is issued even if the definition itself
+provides a prototype.  The aim is to detect global functions that fail
+to be declared in header files.
+.TP
+.B \-Wmissing\-declarations
+Warn if a global function is defined without a previous declaration.
+Do so even if the definition itself provides a prototype.
+Use this option to detect global functions that are not declared in
+header files.
+.TP
+.B \-Wredundant-decls
+Warn if anything is declared more than once in the same scope, even in
+cases where multiple declaration is valid and changes nothing.
+.TP
+.B \-Wnested-externs
+Warn if an \c
+.B extern\c
+\& declaration is encountered within an function.
+.TP
+.B \-Wenum\-clash
+Warn about conversion between different enumeration types (C++ only).
+.TP
+.B \-Woverloaded\-virtual
+(C++ only.)
+In a derived class, the definitions of virtual functions must match
+the type signature of a virtual function declared in the base class.
+Use this option to request warnings when a derived class declares a
+function that may be an erroneous attempt to define a virtual
+function: that is, warn when a function with the same name as a
+virtual function in the base class, but with a type signature that
+doesn't match any virtual functions from the base class.
+.TP
+.B \-Winline
+Warn if a function can not be inlined, and either it was declared as inline,
+or else the
+.B \-finline\-functions
+option was given.
+.TP
+.B \-Werror
+Treat warnings as errors; abort compilation after any warning.
+.SH DEBUGGING OPTIONS
+GNU CC has various special options that are used for debugging
+either your program or GCC:
+.TP
+.B \-g
+Produce debugging information in the operating system's native format
+(stabs, COFF, XCOFF, or DWARF).  GDB can work with this debugging
+information.
+.Sp
+On most systems that use stabs format, `\|\c
+.B \-g\c
+\&\|' enables use of extra
+debugging information that only GDB can use; this extra information
+makes debugging work better in GDB but will probably make other debuggers
+crash or
+refuse to read the program.  If you want to control for certain whether
+to generate the extra information, use `\|\c
+.B \-gstabs+\c
+\&\|', `\|\c
+.B \-gstabs\c
+\&\|',
+`\|\c
+.B \-gxcoff+\c
+\&\|', `\|\c
+.B \-gxcoff\c
+\&\|', `\|\c
+.B \-gdwarf+\c
+\&\|', or `\|\c
+.B \-gdwarf\c
+\&\|'
+(see below).
+.Sp
+Unlike most other C compilers, GNU CC allows you to use `\|\c
+.B \-g\c
+\&\|' with
+`\|\c
+.B \-O\c
+\&\|'.  The shortcuts taken by optimized code may occasionally
+produce surprising results: some variables you declared may not exist
+at all; flow of control may briefly move where you did not expect it;
+some statements may not be executed because they compute constant
+results or their values were already at hand; some statements may
+execute in different places because they were moved out of loops.
+.Sp
+Nevertheless it proves possible to debug optimized output.  This makes
+it reasonable to use the optimizer for programs that might have bugs.
+.PP
+The following options are useful when GNU CC is generated with the
+capability for more than one debugging format.
+.TP
+.B \-ggdb
+Produce debugging information in the native format (if that is supported),
+including GDB extensions if at all possible.
+.TP
+.B \-gstabs
+Produce debugging information in stabs format (if that is supported),
+without GDB extensions.  This is the format used by DBX on most BSD
+systems.
+.TP
+.B \-gstabs+
+Produce debugging information in stabs format (if that is supported),
+using GNU extensions understood only by the GNU debugger (GDB).  The
+use of these extensions is likely to make other debuggers crash or
+refuse to read the program.
+.TP
+.B \-gcoff
+Produce debugging information in COFF format (if that is supported).
+This is the format used by SDB on most System V systems prior to
+System V Release 4.
+.TP
+.B \-gxcoff
+Produce debugging information in XCOFF format (if that is supported).
+This is the format used by the DBX debugger on IBM RS/6000 systems.
+.TP
+.B \-gxcoff+
+Produce debugging information in XCOFF format (if that is supported),
+using GNU extensions understood only by the GNU debugger (GDB).  The
+use of these extensions is likely to make other debuggers crash or
+refuse to read the program.
+.TP
+.B \-gdwarf
+Produce debugging information in DWARF format (if that is supported).
+This is the format used by SDB on most System V Release 4 systems.
+.TP
+.B \-gdwarf+
+Produce debugging information in DWARF format (if that is supported),
+using GNU extensions understood only by the GNU debugger (GDB).  The
+use of these extensions is likely to make other debuggers crash or
+refuse to read the program.

+Request debugging information and also use \c
+.I level\c
+\& to specify how
+much information.  The default level is 2.
+.Sp
+Level 1 produces minimal information, enough for making backtraces in
+parts of the program that you don't plan to debug.  This includes
+descriptions of functions and external variables, but no information
+about local variables and no line numbers.
+.Sp
+Level 3 includes extra information, such as all the macro definitions
+present in the program.  Some debuggers support macro expansion when

+.TP
+.B \-p
+Generate extra code to write profile information suitable for the

+.TP
+.B \-pg
+Generate extra code to write profile information suitable for the
+analysis program \c
+.B gprof\c
+\&.
+.TP
+.B \-a
+Generate extra code to write profile information for basic blocks,
+which will record the number of times each basic block is executed.
+This data could be analyzed by a program like \c
+.B tcov\c
+\&.  Note,
+however, that the format of the data is not what \c
+.B tcov\c
+\& expects.
+Eventually GNU \c
+.B gprof\c
+\& should be extended to process this data.
+.TP
+.B \-ax
+Generate extra code to read basic block profiling parameters from 
+file `bb.in' and write profiling results to file `bb.out'.
+`bb.in' contains a list of functions. Whenever a function on the list
+is entered, profiling is turned on. When the outmost function is left,
+profiling is turned off. If a function name is prefixed with `-'
+the function is excluded from profiling. If a function name is not
+unique it can be disambiguated by writing
+`/path/filename.d:functionname'. `bb.out' will list some available
+filenames.
+Four function names have a special meaning:
+`__bb_jumps__' will cause jump frequencies to be written to `bb.out'.
+`__bb_trace__' will cause the sequence of basic blocks to be piped 
+into `gzip' and written to file `bbtrace.gz'.
+`__bb_hidecall__' will cause call instructions to be excluded from
+the trace.
+`__bb_showret__' will cause return instructions to be included in
+the trace.
+.TP
+.BI "\-d" "letters"
+Says to make debugging dumps during compilation at times specified by
+.I letters\c
+\&.  This is used for debugging the compiler.  The file names
+for most of the dumps are made by appending a word to the source file
+name (e.g.  `\|\c
+.B foo.c.rtl\c
+\&\|' or `\|\c
+.B foo.c.jump\c
+\&\|').
+.TP
+.B \-dM
+Dump all macro definitions, at the end of preprocessing, and write no
+output.
+.TP
+.B \-dN
+Dump all macro names, at the end of preprocessing.
+.TP

+Dump all macro definitions, at the end of preprocessing, in addition to

+Dump debugging information during parsing, to standard error.
+.TP
+.B \-dr
+Dump after RTL generation, to `\|\c

+.TP
+.B \-dx
+Just generate RTL for a function instead of compiling it.  Usually used
+with `\|\c

+.B \-dm
+Print statistics on memory usage, at the end of the run, to

+.TP
+.B \-dp
+Annotate the assembler output with a comment indicating which
+pattern and alternative was used.
+.TP
+.B \-fpretend\-float
+When running a cross-compiler, pretend that the target machine uses the

+output of the actual floating constants, but the actual instruction
+sequence will probably be the same as GNU CC would make when running on
+the target machine.
+.TP
+.B \-save\-temps
+Store the usual \*(lqtemporary\*(rq intermediate files permanently; place them

+compiling `\|\c
+.B foo.c\c
+\&\|' with `\|\c

+.SH OPTIMIZATION OPTIONS
+These options control various sorts of optimizations:
+.TP
+.B \-O
+.TP
+.B \-O1
+Optimize.  Optimizing compilation takes somewhat more time, and a lot
+more memory for a large function.
+.Sp
+Without `\|\c
+.B \-O\c
+\&\|', the compiler's goal is to reduce the cost of
+compilation and to make debugging produce the expected results.
+Statements are independent: if you stop the program with a breakpoint
+between statements, you can then assign a new value to any variable or
+change the program counter to any other statement in the function and
+get exactly the results you would expect from the source code.
+.Sp
+Without `\|\c
+.B \-O\c
+\&\|', only variables declared \c
+.B register\c
+\& are
+allocated in registers.  The resulting compiled code is a little worse
+than produced by PCC without `\|\c
+.B \-O\c
+\&\|'.
+.Sp
+With `\|\c
+.B \-O\c
+\&\|', the compiler tries to reduce code size and execution
+time.
+.Sp
+When you specify `\|\c
+.B \-O\c
+\&\|', the two options `\|\c
+.B \-fthread\-jumps\c

+.B \-fdelayed\-branch\c
+\&\|' option is turned on.  For those machines that can support debugging even
+without a frame pointer, the `\|\c
+.B \-fomit\-frame\-pointer\c
+\&\|' option is turned on.  On some machines other flags may also be turned on.
+.TP
+.B \-O2
+Optimize even more.  Nearly all supported optimizations that do not
+involve a space-speed tradeoff are performed.  Loop unrolling and function
+inlining are not done, for example.  As compared to
+.B \-O\c
+\&,
+this option increases both compilation time and the performance of the
+generated code.
+.TP
+.B \-O3
+Optimize yet more. This turns on everything
+.B \-O2
+does, along with also turning on
+.B \-finline\-functions.
+.TP
+.B \-O0
+Do not optimize.
+.Sp
+If you use multiple
+.B \-O
+options, with or without level numbers, the last such option is the
+one that is effective.
+.PP
+Options of the form `\|\c
+.B \-f\c
+.I flag\c
+\&\c
+\&\|' specify machine-independent
+flags.  Most flags have both positive and negative forms; the negative
+form of `\|\c
+.B \-ffoo\c
+\&\|' would be `\|\c
+.B \-fno\-foo\c
+\&\|'.  The following list shows
+only one form\(em\&the one which is not the default.
+You can figure out the other form by either removing `\|\c
+.B no\-\c
+\&\|' or
+adding it.
+.TP
+.B \-ffloat\-store
+Do not store floating point variables in registers.  This
+prevents undesirable excess precision on machines such as the
+68000 where the floating registers (of the 68881) keep more
+precision than a \c
+.B double\c
+\& is supposed to have.
+.Sp
+For most programs, the excess precision does only good, but a few
+programs rely on the precise definition of IEEE floating point.
+Use `\|\c
+.B \-ffloat\-store\c
+\&\|' for such programs.
+.TP
+.B \-fmemoize\-lookups
+.TP
+.B \-fsave\-memoized
+Use heuristics to compile faster (C++ only).  These heuristics are not
+enabled by default, since they are only effective for certain input
+files.  Other input files compile more slowly.
+.Sp
+The first time the compiler must build a call to a member function (or
+reference to a data member), it must (1) determine whether the class
+implements member functions of that name; (2) resolve which member
+function to call (which involves figuring out what sorts of type
+conversions need to be made); and (3) check the visibility of the member
+function to the caller.  All of this adds up to slower compilation.
+Normally, the second time a call is made to that member function (or
+reference to that data member), it must go through the same lengthy
+process again.  This means that code like this
+.Sp
+\&  cout << "This " << p << " has " << n << " legs.\en";
+.Sp
+makes six passes through all three steps.  By using a software cache,
+a \*(lqhit\*(rq significantly reduces this cost.  Unfortunately, using the
+cache introduces another layer of mechanisms which must be implemented,
+and so incurs its own overhead.  `\|\c
+.B \-fmemoize\-lookups\c
+\&\|' enables
+the software cache.
+.Sp
+Because access privileges (visibility) to members and member functions
+may differ from one function context to the next,
+.B g++
+may need to flush the cache.  With the `\|\c
+.B \-fmemoize\-lookups\c
+\&\|' flag, the cache is flushed after every
+function that is compiled.  The `\|\c
+\-fsave\-memoized\c
+\&\|' flag enables the same software cache, but when the compiler
+determines that the context of the last function compiled would yield
+the same access privileges of the next function to compile, it
+preserves the cache.
+This is most helpful when defining many member functions for the same
+class: with the exception of member functions which are friends of
+other classes, each member function has exactly the same access
+privileges as every other, and the cache need not be flushed.
+.TP
+.B \-fno\-default\-inline
+Don't make member functions inline by default merely because they are
+defined inside the class scope (C++ only).
+.TP
+.B \-fno\-defer\-pop
+Always pop the arguments to each function call as soon as that
+function returns.  For machines which must pop arguments after a
+function call, the compiler normally lets arguments accumulate on the
+stack for several function calls and pops them all at once.
+.TP
+.B \-fforce\-mem
+Force memory operands to be copied into registers before doing
+arithmetic on them.  This may produce better code by making all
+memory references potential common subexpressions.  When they are
+not common subexpressions, instruction combination should
+eliminate the separate register-load.  I am interested in hearing
+about the difference this makes.
+.TP
+.B \-fforce\-addr
+Force memory address constants to be copied into registers before
+doing arithmetic on them.  This may produce better code just as
+`\|\c
+.B \-fforce\-mem\c
+\&\|' may.  I am interested in hearing about the
+difference this makes.
+.TP
+.B \-fomit\-frame\-pointer
+Don't keep the frame pointer in a register for functions that
+don't need one.  This avoids the instructions to save, set up and
+restore frame pointers; it also makes an extra register available
+in many functions.  \c
+.I It also makes debugging impossible on most machines\c
+\&.
+.Sp
+On some machines, such as the Vax, this flag has no effect, because
+the standard calling sequence automatically handles the frame pointer
+and nothing is saved by pretending it doesn't exist.  The
+machine-description macro \c
+.B FRAME_POINTER_REQUIRED\c
+\& controls
+whether a target machine supports this flag.
+.TP
+.B \-finline\-functions
+Integrate all simple functions into their callers.  The compiler
+heuristically decides which functions are simple enough to be worth
+integrating in this way.
+.Sp
+If all calls to a given function are integrated, and the function is
+declared \c
+.B static\c
+\&, then GCC normally does not output the function as
+assembler code in its own right.
+.TP
+.B \-fcaller\-saves
+Enable values to be allocated in registers that will be clobbered by
+function calls, by emitting extra instructions to save and restore the
+registers around such calls.  Such allocation is done only when it
+seems to result in better code than would otherwise be produced.
+.Sp
+This option is enabled by default on certain machines, usually those
+which have no call-preserved registers to use instead.
+.TP
+.B \-fkeep\-inline\-functions
+Even if all calls to a given function are integrated, and the function
+is declared \c
+.B static\c
+\&, nevertheless output a separate run-time
+callable version of the function.
+.TP
+.B \-fno\-function\-cse
+Do not put function addresses in registers; make each instruction that
+calls a constant function contain the function's address explicitly.
+.Sp
+This option results in less efficient code, but some strange hacks
+that alter the assembler output may be confused by the optimizations
+performed when this option is not used.
+.TP
+.B \-fno\-peephole
+Disable any machine-specific peephole optimizations.
+.TP
+.B \-ffast-math
+This option allows GCC to violate some ANSI or IEEE rules/specifications
+in the interest of optimizing code for speed.  For example, it allows
+the compiler to assume arguments to the \c
+.B sqrt\c
+\& function are
+non-negative numbers.
+.Sp
+This option should never be turned on by any `\|\c
+.B \-O\c
+\&\|' option since
+it can result in incorrect output for programs which depend on
+an exact implementation of IEEE or ANSI rules/specifications for
+math functions.
+.PP
+The following options control specific optimizations.  The `\|\c
+.B \-O2\c
+\&\|'
+option turns on all of these optimizations except `\|\c
+.B \-funroll\-loops\c
+\&\|'
+and `\|\c
+.B \-funroll\-all\-loops\c
+\&\|'.
+.PP
+The `\|\c
+.B \-O\c
+\&\|' option usually turns on
+the `\|\c
+.B \-fthread\-jumps\c
+\&\|' and `\|\c
+.B \-fdelayed\-branch\c
+\&\|' options, but
+specific machines may change the default optimizations.
+.PP
+You can use the following flags in the rare cases when \*(lqfine-tuning\*(rq
+of optimizations to be performed is desired.
+.TP
+.B \-fstrength\-reduce
+Perform the optimizations of loop strength reduction and
+elimination of iteration variables.
+.TP
+.B \-fthread\-jumps
+Perform optimizations where we check to see if a jump branches to a
+location where another comparison subsumed by the first is found.  If
+so, the first branch is redirected to either the destination of the
+second branch or a point immediately following it, depending on whether
+the condition is known to be true or false.
+.TP
+.B \-funroll\-loops
+Perform the optimization of loop unrolling.  This is only done for loops
+whose number of iterations can be determined at compile time or run time.
+.TP
+.B \-funroll\-all\-loops
+Perform the optimization of loop unrolling.  This is done for all loops.
+This usually makes programs run more slowly.
+.TP
+.B \-fcse\-follow\-jumps
+In common subexpression elimination, scan through jump instructions
+when the target of the jump is not reached by any other path.  For
+example, when CSE encounters an \c
+.B if\c
+\& statement with an
+.B else\c
+\& clause, CSE will follow the jump when the condition
+tested is false.
+.TP
+.B \-fcse\-skip\-blocks
+This is similar to `\|\c
+.B \-fcse\-follow\-jumps\c
+\&\|', but causes CSE to
+follow jumps which conditionally skip over blocks.  When CSE
+encounters a simple \c
+.B if\c
+\& statement with no else clause,
+`\|\c
+.B \-fcse\-skip\-blocks\c
+\&\|' causes CSE to follow the jump around the
+body of the \c
+.B if\c
+\&.
+.TP
+.B \-frerun\-cse\-after\-loop
+Re-run common subexpression elimination after loop optimizations has been
+performed.
+.TP
+.B \-felide\-constructors
+Elide constructors when this seems plausible (C++ only).  With this
+flag, GNU C++ initializes \c
+.B y\c
+\& directly from the call to \c
+.B foo
+without going through a temporary in the following code:
+.Sp
+A foo ();
+A y = foo ();
+.Sp
+Without this option, GNU C++ first initializes \c
+.B y\c
+\& by calling the
+appropriate constructor for type \c
+.B A\c
+\&; then assigns the result of
+.B foo\c
+\& to a temporary; and, finally, replaces the initial value of
+`\|\c
+.B y\c
+\&\|' with the temporary.
+.Sp
+The default behavior (`\|\c
+.B \-fno\-elide\-constructors\c
+\&\|') is specified by
+the draft ANSI C++ standard.  If your program's constructors have side
+effects, using `\|\c
+.B \-felide-constructors\c
+\&\|' can make your program act
+differently, since some constructor calls may be omitted.
+.TP
+.B \-fexpensive\-optimizations
+Perform a number of minor optimizations that are relatively expensive.
+.TP
+.B \-fdelayed\-branch
+If supported for the target machine, attempt to reorder instructions
+to exploit instruction slots available after delayed branch
+instructions.
+.TP
+.B \-fschedule\-insns
+If supported for the target machine, attempt to reorder instructions to
+eliminate execution stalls due to required data being unavailable.  This
+helps machines that have slow floating point or memory load instructions
+by allowing other instructions to be issued until the result of the load
+or floating point instruction is required.
+.TP
+.B \-fschedule\-insns2
+Similar to `\|\c
+.B \-fschedule\-insns\c
+\&\|', but requests an additional pass of
+instruction scheduling after register allocation has been done.  This is
+especially useful on machines with a relatively small number of
+registers and where memory load instructions take more than one cycle.
+.SH TARGET OPTIONS
+By default, GNU CC compiles code for the same type of machine that you
+are using.  However, it can also be installed as a cross-compiler, to
+compile for some other type of machine.  In fact, several different
+configurations of GNU CC, for different target machines, can be
+installed side by side.  Then you specify which one to use with the
+`\|\c
+.B \-b\c
+\&\|' option.
+.PP
+In addition, older and newer versions of GNU CC can be installed side
+by side.  One of them (probably the newest) will be the default, but
+you may sometimes wish to use another.
+.TP
+.BI "\-b " "machine"
+The argument \c
+.I machine\c
+\& specifies the target machine for compilation.
+This is useful when you have installed GNU CC as a cross-compiler.
+.Sp
+The value to use for \c
+.I machine\c
+\& is the same as was specified as the
+machine type when configuring GNU CC as a cross-compiler.  For
+example, if a cross-compiler was configured with `\|\c
+.B configure
+i386v\c
+\&\|', meaning to compile for an 80386 running System V, then you
+would specify `\|\c
+.B \-b i386v\c
+\&\|' to run that cross compiler.
+.Sp
+When you do not specify `\|\c
+.B \-b\c
+\&\|', it normally means to compile for
+the same type of machine that you are using.
+.TP
+.BI "\-V " "version"
+The argument \c
+.I version\c
+\& specifies which version of GNU CC to run.
+This is useful when multiple versions are installed.  For example,
+.I version\c
+\& might be `\|\c
+.B 2.0\c
+\&\|', meaning to run GNU CC version 2.0.
+.Sp
+The default version, when you do not specify `\|\c
+.B \-V\c
+\&\|', is controlled
+by the way GNU CC is installed.  Normally, it will be a version that
+is recommended for general use.
+.SH MACHINE DEPENDENT OPTIONS
+Each of the target machine types can have its own special options,
+starting with `\|\c
+.B \-m\c
+\&\|', to choose among various hardware models or
+configurations\(em\&for example, 68010 vs 68020, floating coprocessor or
+none.  A single installed version of the compiler can compile for any
+model or configuration, according to the options specified.
+.PP
+Some configurations of the compiler also support additional special
+options, usually for command-line compatibility with other compilers on
+the same platform.
+.PP
+These are the `\|\c
+.B \-m\c
+\&\|' options defined for the 68000 series:
+.TP
+.B \-m68000
+.TP
+.B \-mc68000
+Generate output for a 68000.  This is the default when the compiler is
+configured for 68000-based systems.
+.TP
+.B \-m68020
+.TP
+.B \-mc68020
+Generate output for a 68020 (rather than a 68000).  This is the
+default when the compiler is configured for 68020-based systems.
+.TP
+.B \-m68881
+Generate output containing 68881 instructions for floating point.
+This is the default for most 68020-based systems unless
+.B \-nfp
+was specified when the compiler was configured.
+.TP
+.B \-m68030
+Generate output for a 68030.  This is the default when the compiler is
+configured for 68030-based systems.
+.TP
+.B \-m68040
+Generate output for a 68040.  This is the default when the compiler is
+configured for 68040-based systems.
+.TP
+.B \-m68020\-40
+Generate output for a 68040, without using any of the new instructions.
+This results in code which can run relatively efficiently on either a
+68020/68881 or a 68030 or a 68040.
+.TP
+.B \-mfpa
+Generate output containing Sun FPA instructions for floating point.
+.TP
+.B \-msoft\-float
+Generate output containing library calls for floating point.
+.I
+WARNING:
+the requisite libraries are not part of GNU CC.  Normally the
+facilities of the machine's usual C compiler are used, but this can't
+be done directly in cross-compilation.  You must make your own
+arrangements to provide suitable library functions for cross-compilation.
+.TP
+.B \-mshort
+Consider type \c
+.B int\c
+\& to be 16 bits wide, like \c
+.B short int\c
+\&.
+.TP
+.B \-mnobitfield
+Do not use the bit-field instructions.  `\|\c
+.B \-m68000\c
+\&\|' implies
+`\|\c
+.B \-mnobitfield\c
+\&\|'.
+.TP
+.B \-mbitfield
+Do use the bit-field instructions.  `\|\c
+.B \-m68020\c
+\&\|' implies
+`\|\c
+.B \-mbitfield\c
+\&\|'.  This is the default if you use the unmodified
+sources.
+.TP
+.B \-mrtd
+Use a different function-calling convention, in which functions
+that take a fixed number of arguments return with the \c
+.B rtd
+instruction, which pops their arguments while returning.  This
+saves one instruction in the caller since there is no need to pop
+the arguments there.
+.Sp
+This calling convention is incompatible with the one normally
+used on Unix, so you cannot use it if you need to call libraries
+compiled with the Unix compiler.
+.Sp
+Also, you must provide function prototypes for all functions that
+take variable numbers of arguments (including \c
+.B printf\c
+\&);
+otherwise incorrect code will be generated for calls to those
+functions.
+.Sp
+In addition, seriously incorrect code will result if you call a
+function with too many arguments.  (Normally, extra arguments are
+harmlessly ignored.)
+.Sp
+The \c
+.B rtd\c
+\& instruction is supported by the 68010 and 68020
+processors, but not by the 68000.
+.PP
+These `\|\c
+.B \-m\c
+\&\|' options are defined for the Vax:
+.TP
+.B \-munix
+Do not output certain jump instructions (\c
+.B aobleq\c
+\& and so on)
+that the Unix assembler for the Vax cannot handle across long
+ranges.
+.TP
+.B \-mgnu
+Do output those jump instructions, on the assumption that you
+will assemble with the GNU assembler.
+.TP
+.B \-mg
+Output code for g-format floating point numbers instead of d-format.
+.PP
+These `\|\c
+.B \-m\c
+\&\|' switches are supported on the SPARC:
+.PP
+.B \-mfpu
+.TP
+.B \-mhard\-float
+Generate output containing floating point instructions.  This is the
+default.
+.PP
+.B \-mno\-fpu
+.TP
+.B \-msoft\-float
+Generate output containing library calls for floating point.
+.I Warning:
+there is no GNU floating-point library for SPARC.
+Normally the facilities of the machine's usual C compiler are used, but
+this cannot be done directly in cross-compilation.  You must make your
+own arrangements to provide suitable library functions for
+cross-compilation.
+.Sp
+.B \-msoft\-float
+changes the calling convention in the output file;
+therefore, it is only useful if you compile
+.I all
+of a program with this option.
+.PP
+.B \-mno\-epilogue
+.TP
+.B \-mepilogue
+With
+.B \-mepilogue
+(the default), the compiler always emits code for
+function exit at the end of each function.  Any function exit in
+the middle of the function (such as a return statement in C) will
+generate a jump to the exit code at the end of the function.
+.Sp
+With
+.BR \-mno\-epilogue ,
+the compiler tries to emit exit code inline at every function exit.
+.PP
+.B \-mno\-v8
+.TP
+.B \-mv8
+.TP
+.B \-msparclite
+These three options select variations on the SPARC architecture.
+.Sp
+By default (unless specifically configured for the Fujitsu SPARClite),
+GCC generates code for the v7 variant of the SPARC architecture.
+.Sp
+.B \-mv8
+will give you SPARC v8 code.  The only difference from v7
+code is that the compiler emits the integer multiply and integer
+divide instructions which exist in SPARC v8 but not in SPARC v7.
+.Sp
+.B \-msparclite
+will give you SPARClite code.  This adds the integer
+multiply, integer divide step and scan (ffs) instructions which
+exist in SPARClite but not in SPARC v7.
+.PP
+.B \-mcypress
+.TP
+.B \-msupersparc
+These two options select the processor for which the code is optimised.
+.Sp
+With
+.B \-mcypress
+(the default), the compiler optimises code for the Cypress CY7C602 chip, as
+used in the SparcStation/SparcServer 3xx series. This is also appropriate for
+the older SparcStation 1, 2, IPX etc.
+.Sp
+With
+.B \-msupersparc
+the compiler optimises code for the SuperSparc cpu, as used in the SparcStation
+10, 1000 and 2000 series. This flag also enables use of the full SPARC v8
+instruction set.
+.PP
+These `\|\c
+.B \-m\c
+\&\|' options are defined for the Convex:
+.TP
+.B \-mc1
+Generate output for a C1.  This is the default when the compiler is
+configured for a C1.
+.TP
+.B \-mc2
+Generate output for a C2.  This is the default when the compiler is
+configured for a C2.
+.TP
+.B \-margcount
+Generate code which puts an argument count in the word preceding each
+argument list.  Some nonportable Convex and Vax programs need this word.
+(Debuggers don't, except for functions with variable-length argument
+lists; this info is in the symbol table.)
+.TP
+.B \-mnoargcount
+Omit the argument count word.  This is the default if you use the
+unmodified sources.
+.PP
+These `\|\c
+.B \-m\c
+\&\|' options are defined for the AMD Am29000:
+.TP
+.B \-mdw
+Generate code that assumes the DW bit is set, i.e., that byte and
+halfword operations are directly supported by the hardware.  This is the
+default.
+.TP
+.B \-mnodw
+Generate code that assumes the DW bit is not set.
+.TP
+.B \-mbw
+Generate code that assumes the system supports byte and halfword write
+operations.  This is the default.
+.TP
+.B \-mnbw
+Generate code that assumes the systems does not support byte and
+halfword write operations.  This implies `\|\c
+.B \-mnodw\c
+\&\|'.
+.TP
+.B \-msmall
+Use a small memory model that assumes that all function addresses are
+either within a single 256 KB segment or at an absolute address of less
+than 256K.  This allows the \c
+.B call\c
+\& instruction to be used instead
+of a \c
+.B const\c
+\&, \c
+.B consth\c
+\&, \c
+.B calli\c
+\& sequence.
+.TP
+.B \-mlarge
+Do not assume that the \c
+.B call\c

+default.
+.TP
+.B \-m29050
+Generate code for the Am29050.
+.TP
+.B \-m29000
+Generate code for the Am29000.  This is the default.
+.TP
+.B \-mkernel\-registers
+Generate references to registers \c
+.B gr64-gr95\c
+\& instead of
+.B gr96-gr127\c
+\&.  This option can be used when compiling kernel code
+that wants a set of global registers disjoint from that used by
+user-mode code.
+.Sp
+Note that when this option is used, register names in `\|\c
+.B \-f\c
+\&\|' flags
+must use the normal, user-mode, names.
+.TP
+.B \-muser\-registers
+Use the normal set of global registers, \c
+.B gr96-gr127\c
+\&.  This is the
+default.
+.TP
+.B \-mstack\-check
+Insert a call to \c
+.B _\|_msp_check\c
+\& after each stack adjustment.  This
+is often used for kernel code.
+.PP
+These `\|\c

+.B \-m88000
+Generate code that works well on both the m88100 and the

+.TP
+.B \-m88100
+Generate code that works best for the m88100, but that also
+runs on the m88110.

+.B \-m88110
+Generate code that works best for the m88110, and may not run

+Include an \c

+\& directive in the assembler output recording the
+source file name, compiler name and version, timestamp, and compilation
+flags used.
+.TP
+.B \-mno\-underscores
+In assembler output, emit symbol names without adding an underscore
+character at the beginning of each name.  The default is to use an
+underscore as prefix on each name.
+.TP
+.B \-mno\-check\-zero\-division
+.TP
+.B \-mcheck\-zero\-division
+Early models of the 88K architecture had problems with division by zero;
+in particular, many of them didn't trap.  Use these options to avoid
+including (or to include explicitly) additional code to detect division
+by zero and signal an exception.  All GCC configurations for the 88K use
+`\|\c

+.TP
+.B \-mno\-ocs\-debug\-info
+Include (or omit) additional debugging information (about

+.TP
+.B \-mocs\-frame\-position
+.TP
+.B \-mno\-ocs\-frame\-position
+Force (or do not require) register values to be stored in a particular

+Control how to store function arguments in stack frames.
+`\|\c

+GNU CC always guarantees consistency by default, for the preferred
+processor submodel.  How this is done depends on the submodel.
+.Sp
+The m88100 processor does not reorder memory references and so always
+provides sequential consistency.  If you use `\|\c

+.Sp
+The order of memory references made by the m88110 processor does not
+always match the order of the instructions requesting those references.
+In particular, a load instruction may execute before a preceding store
+instruction.  Such reordering violates sequential consistency of

+you use `\|\c

+.TP
+.B \-fnonnull\-objects
+Assume that objects reached through references are not null
+(C++ only).
+.Sp
+Normally, GNU C++ makes conservative assumptions about objects reached

+.Sp
+Checking that references of this sort have non-null values requires
+extra code, however, and it is unnecessary for many programs.  You can

+.TP
+.B \-fpcc\-struct\-return
+Use the same convention for returning \c

+\& and \c
+.B union
+values that is used by the usual C compiler on your system.  This
+convention is less efficient for small structures, and on many
+machines it fails to be reentrant; but it has the advantage of
+allowing intercallability between GCC-compiled code and PCC-compiled
+code.
+.TP
+.B \-freg\-struct\-return
+Use the convention that

+.Sp
+If you specify neither
+.B \-fpcc\-struct\-return

+.B \-fshort\-enums
+Allocate to an \c
+.B enum\c

+.TP
+.B \-fshared\-data
+Requests that the data and non-\c
+.B const\c

+compilation be shared data rather than private data.  The distinction
+makes sense only on certain operating systems, where shared data is
+shared between processes running the same program, while private data
+exists in one copy per process.
+.TP
+.B \-fno\-common
+Allocate even uninitialized global variables in the bss section of the
+object file, rather than generating them as common blocks.  This has the
+effect that if the same variable is declared (without \c

+two different compilations, you will get an error when you link them.
+The only reason this might be useful is if you wish to verify that the

+.SH PRAGMAS
+Two `\|\c
+.B #pragma\c
+\&\|' directives are supported for GNU C++, to permit using the same
+header file for two purposes: as a definition of interfaces to a given
+object class, and as the full definition of the contents of that object class.
+.TP
+.B #pragma interface
+(C++ only.)
+Use this directive in header files that define object classes, to save
+space in most of the object files that use those classes.  Normally,
+local copies of certain information (backup copies of inline member
+functions, debugging information, and the internal tables that
+implement virtual functions) must be kept in each object file that
+includes class definitions.  You can use this pragma to avoid such
+duplication.  When a header file containing `\|\c
+.B #pragma interface\c
+\&\|' is included in a compilation, this auxiliary information
+will not be generated (unless the main input source file itself uses
+`\|\c
+.B #pragma implementation\c
+\&\|').  Instead, the object files will contain references to be
+resolved at link time.
+.TP
+.B #pragma implementation
+.TP
+\fB#pragma implementation "\fP\fIobjects\fP\fB.h"\fP
+(C++ only.)
+Use this pragma in a main input file, when you want full output from
+included header files to be generated (and made globally visible).
+The included header file, in turn, should use `\|\c
+.B #pragma interface\c
+\&\|'.
+Backup copies of inline member functions, debugging information, and
+the internal tables used to implement virtual functions are all
+generated in implementation files.
+.Sp
+If you use `\|\c
+.B #pragma implementation\c
+\&\|' with no argument, it applies to an include file with the same
+basename as your source file; for example, in `\|\c
+.B allclass.cc\c
+\&\|', `\|\c
+.B #pragma implementation\c
+\&\|' by itself is equivalent to `\|\c
+.B
+#pragma implementation "allclass.h"\c
+\&\|'.  Use the string argument if you want a single implementation
+file to include code from multiple header files.
+.Sp
+There is no way to split up the contents of a single header file into
+multiple implementation files.

+1 GCC
+
+ The GCC command invokes the GNU C compiler.
+
+       GCC file-spec
+
+2 Parameters
+
+ file-spec
+
+ A C source file.  If no input file  extension  is  specified,  GNU  C
+ assumes  .C  as  the  default extension unless the /PLUS qualifier is
+ given, in which case .CC is assumed as the default extension.
+
+ If an extension of .CPP is given, then the source file is assumed  to
+ be  the  output of the preprocessor, and thus the preprocessor is not
+ executed.
+
+ If an extension of .S is given, then the source file is assumed to be
+ the  assembly  code output of the compiler, and only the assembler is
+ called to generate an object file.
+
+2 Qualifiers
+
+ GNU C command qualifiers modify the  way  the  compiler  handles  the
+ compilation.
+
+ The following is the list of available qualifiers for GNU C:
+
+       /CASE_HACK
+       /CC1_OPTIONS=(option [,option...]])
+       /DEBUG
+       /DEFINE=(identifier[=definition][,...])
+       /G_FLOAT
+       /INCLUDE_DIRECTORY=(path [,path...]])
+       /LIST[=filename]
+       /MACHINE_CODE
+       /OBJECT[=filename]
+       /OPTIMIZE
+       /PLUS
+       /PROFILE[=identifier]
+       /SCAN=(file[,file...])
+       /SHOW[=option]
+       /UNDEFINE=(identifier[,identifier,...])
+       /VERBOSE
+       /VERSION
+       /WARNING
+
+2 Linking
+
+ When linking programs compiled with GNU C, you should include the GNU
+ C library before the VAX C library.  For example,
+
+   LINK object-file,GNU_CC:[000000]GCCLIB/LIB,SYS$LIBRARY:VAXCRTL/LIB
+
+ You can also link your program with the shared VAX C  library.   This
+ can reduce the size of the .EXE file, as well as make it smaller when
+ it's running.  For example,
+
+   $ LINK object-file, GNU_CC:[000000]GCCLIB/LIB,SYS$INPUT/OPT
+   SYS$SHARE:VAXCRTL/SHARE
+
+ (If you use the second example and type it in by  hand,  be  sure  to
+ type ^Z after the last carriage return).  A simpler alternative would
+ be to place the single line:
+
+   SYS$SHARE:VAXCRTL/SHARE
+
+ into a file called VAXCRTL.OPT, and then use the link command:
+
+   $ LINK object-file, GNU_CC:[000000]GCCLIB/LIB,VAXCRTL.OPT/OPT
+
+ If a program has  been  compiled  with  /G_FLOAT,  then  the  linking
+ instructions  are  slightly  different.   If you are linking with the
+ non-shared library, then the command that you should use would be:
+
+   LINK object-file,GNU_CC:[000000]GCCLIB/LIB,SYS$LIBRARY:VAXCRTLG/LIB -
+                                ,SYS$LIBRARY:VAXCRTL/LIB
+
+ Note that both VAXCRTL and VAXCRTLG must be linked to.   If  you  are
+ using the shared VAX C library, then you should use a command like:
+
+   $ LINK object-file, GNU_CC:[000000]GCCLIB/LIB,SYS$INPUT:/OPTIONS
+   SYS$SHARE:VAXCRTLG/SHARE
+
+ In the case of the sharable library, only one  library  needs  to  be
+ linked to.
+
+ If you need to link to libg++, it  is  easiest  to  use  the  command
+ procedure supplied with libg++ to link your program.
+
+2 /CASE_HACK
+
+   /[NO]CASE_HACK      D=/CASE_HACK
+
+ Since the VMS Linker  and  Librarian  are  not  case  sensitive  with
+ respect  to  symbol names, a "case-hack" is appended to a symbol name
+ when the symbol contains upper case characters.
+
+ There are cases where this is undesirable, (mainly when using certain
+ applications  where modules have been precompiled, perhaps in another
+ language) and we want to compile  without  case  hacking.   In  these
+ cases the /NOCASE_HACK switch disables case hacking.
+
+2 /CC1_OPTIONS
+
+ This specifies additional  switches  to  the  compiler  itself  which
+ cannot be set by means of the compiler driver.
+
+2 /DEBUG
+
+ /DEBUG includes additional information in the object file  output  so
+ that the program can be debugged with the VAX Symbolic Debugger.
+
+ To use the debugger it is also necessary to link the debugger to your
+ program, which is done by specifying the /DEBUG qualifier to the link
+ command.  With the  debugger  it  is  possible  to  set  breakpoints,
+ examine  variables,  and  set  variables  to new values.  See the VAX
+ Symbolic Debugger manual for more information, or  type  "HELP"  from
+ the debugger prompt.
+
+2 /DEFINE
+
+ /DEFINE=(identifier[=definition][,...])
+
+ /DEFINE defines a string or macro ('definition')  to  be  substituted
+ for  every  occurrence of a given string ('identifier') in a program.
+ It is equivalent to the #define preprocessor directive.
+
+ All definitions and identifiers are  converted  to  uppercase  unless
+ they are in quotation marks.
+
+ The simple form of the /DEFINE qualifier:
+
+    /DEFINE=vms
+
+ results in a definition equivalent to the preprocessor directive:
+
+  #define VMS 1
+
+ You must enclose macro definitions in quotation  marks,  as  in  this
+ example:
+
+  /DEFINE="C(x)=((x) & 0xff)"
+
+ This definition is the same as the preprocessor definition:
+
+  #define C(x) ((x) & 0xff)
+
+ If more than one /DEFINE is present on the GCC command line, only the
+ last /DEFINE is used.
+
+ If both /DEFINE and /UNDEFINE are present on a command line,  /DEFINE
+ is evaluated before /UNDEFINE.
+
+2 /G_FLOAT
+
+ Instructs the compiler to use "G" floating point  arithmetic  instead
+ of  "D".   The  difference  is  that  double precision has a range of
+ approximately +/-0.56e-308 to +/-0.9  e+308,  with  approximately  15
+ decimal digits precision.
+
+ "D" floating point has the same range as  single  precision  floating
+ point, with approximately 17 decimal digits precision.
+
+ If you use the  /G_FLOAT  qualifier,  the  linking  instructions  are
+ different.  See "Linking" for further details.
+
+2 /LIST
+
+ /LIST[=list_file_name]
+
+ This does not generate a listing file in the usual sense, however  it
+ does  direct the compiler to save the preprocessor output.  If a file
+ is not specified, then this output is written into a  file  with  the
+ same name as the source file and an extension of .CPP.
+
+2 /INCLUDE_DIRECTORY
+
+  /INCLUDE_DIRECTORY=(path [,path...])
+
+ The /INCLUDE_DIRECTORY qualifier provides additional  directories  to
+ search  for  user-defined  include  files.   'path'  can  be either a
+ logical name or a directory specification.
+
+ There  are  two  forms  for  specifying  include  files  -   #include
+ "file-spec"  and  #include <file-spec>.  For the #include "file-spec"
+ form, the search order is:
+
+  1.  The directory containing the source file.
+
+  2.  The directories in the /INCLUDE qualifier (if any).
+
+  3.  The directory (or directories) specified in the logical name
+      GNU_CC_INCLUDE.
+
+  4.  The directory (or directories) specified in the logical name
+      SYS$LIBRARY.
+
+  For the #include <file-spec> form, the search order is:
+
+  1.  The directories specified in the /INCLUDE qualifier (if any).
+
+  2.  The directory (or directories) specified in the logical name
+      GNU_CC_INCLUDE.
+
+  3.  The directory (or directories) specified in the logical name
+      SYS$LIBRARY.
+
+2 /MACHINE_CODE
+
+ Tells GNU C to output the machine code  generated  by  the  compiler.
+ The  machine code is output to a file with the same name as the input
+ file, with the extension .S.  An  object  file  is  still  generated,
+ unless /NOOBJ is also specified.
+
+2 /OBJECT
+
+   /OBJECT[=filename]
+   /NOOBJECT
+
+        Controls whether or not an object file  is  generated  by  the
+ compiler.
+
+2 /OPTIMIZE
+
+ /[NO]OPTIMIZE
+
+ Controls whether optimization  is  performed  by  the  compiler.   By
+ default, optimization is on.  /NOOPTIMIZE turns optimization off.
+
+2 /PLUS
+
+ Instructs the compiler driver to use the GNU-C++ compiler instead  of
+ the  GNU-C compiler.  Note that the default extension of source files
+ is .CC when this qualifier is in effect.
+
+2 /PROFILE
+
+ /PROFILE[=identifier]
+
+ Instructs the compiler to generate function profiling code.  You must
+ link  your  program  to  the profiler when you use this options.  The
+ profile statistics are automatically  printed  out  on  the  terminal
+ during  image  exit.  (i.e.  no modifications to your source file are
+ required in order to use the profiler).
+
+ There are three identifiers  that  can  be  used  with  the  /PROFILE
+ switch.   These  are  ALL, FUNCTION, and BLOCK.  If /PROFILE is given
+ without an identifier, then FUNCTION is assumed.
+
+3 Block_Profiler
+
+ The block profiler counts how  many  times  control  of  the  program
+ passes certain points in your program.  This is useful in determining
+ which  portions  of  a  program  would  benefit  from  recoding   for
+ optimization.
+
+ The report for the block profiler contains the  function  name,  file
+ name, PC, and the source file line number as well as the count of how
+ many times control has passed through the specified source line.
+
+3 Function_Profiler
+
+ The function profiler counts how many times each function is entered,
+ and keeps track of how much CPU time is used within each function.
+
+ You should be careful about  interpreting  the  results  of  profiles
+ where  there  are  inline  functions.  When a function is included as
+ inline, then there is no call to the internal data collection routine
+ used  by  the  profiler,  and  thus  there  will be no record of this
+ function being called.  The compiler does generate a callable version
+ of each inline function, and if this called version is used, then the
+ profiler's data collection routine will be called.
+
+2 /SCAN
+
+ /SCAN=(file[,file...])
+
+ This qualifier supplies a list of files that will be read  as  input,
+ and  the output will be discarded before processing the regular input
+ file.  Because the output generated from the files is discarded,  the
+ only  effect  of  this qualifier is to make the macros defined in the
+ files available for use in the main input.
+
+2 /SHOW
+
+ /SHOW[=option]
+
+ This causes the preprocessor to generate information other  than  the
+ preprocessed  input  file.   When this qualifier is used, no assembly
+ code and no object file is generated.
+
+ The output of the preprocessor is placed in the file specified by the
+ /LIST  qualifier, if present.  If the /LIST qualifier is not present,
+ then the output is placed in a file with the same name as  the  input
+ file  with  an  extension  that  depends  upon  which  option that is
+ selected.
+
+3 DEFINITIONS
+
+ This option causes the preprocessor to dump a  list  of  all  of  the
+ definitions  to  the  output  file.   This  is  useful  for debugging
+ purposes, since it lets you determine whether or not  everything  has
+ been defined properly.
+
+ If the default file name is used for the output, the  extension  will
+ be .DEF.
+
+3 RULES
+
+ This option causes the preprocessor to output  a  rule  suitable  for
+ MAKE,  describing  the  dependencies  of  the  main source file.  The
+ preprocessor outputs one MAKE rule containing the  object  file  name
+ for  that  source  file,  a colon, and the names of all the concluded
+ files.  If there are many included files then the rule is split  into
+ several lines using the '\'-newline.
+
+ When using this option, only files included with the "#include "file"
+ directive are mentioned.
+
+ If the default file name is used for the  output,  a  null  extension
+ will be used.
+
+3 ALL
+
+ This option is similar to RULES, except that it also  mentions  files
+ included with the "#include <file.h>" directive.
+
+ If the default file name is used for the  output,  a  null  extension
+ will be used.
+
+2 /UNDEFINE
+
+ /UNDEFINE cancels a macro definition.  Thus, it is the  same  as  the
+ #undef preprocessor directive.
+
+ If more than one /UNDEFINE is present on the GCC command  line,  only
+ the last /UNDEFINE is used.
+
+ If both /DEFINE and /UNDEFINE are present on a command line,  /DEFINE
+ is evaluated before /UNDEFINE.
+
+2 /VERBOSE
+
+ Controls whether the user sees the invocation command strings for the
+ preprocessor,  compiler,  and  assembler.   The compiler also outputs
+ some statistics on time spent in its various phases.
+
+2 /VERSION
+
+ Causes the preprocessor and the compiler to  identify  themselves  by
+ their  version  numbers, and in the case of the compiler, the version
+ number of the compiler that built it.
+
+2 /WARNING
+
+ When this qualifier is present, warnings about usage that  should  be
+ avoided  are given by the compiler.  For more information, see "Using
+ and Porting GNU CC", in the section on command  line  options,  under
+ "-Wall".
+
+ Warnings are also generated by the preprocessor when  this  qualifier
+ is given.
+
+2 Known_Incompatibilities_with_VAX-C
+
+ There are several known incompatibilities between  GNU-C  and  VAX-C.
+ Some  common  ones  will  be  briefly  described  here.   A  complete
+ description can be found in "Using and Porting GNU CC" in the chapter
+ entitled "Using GNU CC on VMS".
+
+     GNU-C provides case hacking as a means of giving case sensitivity
+ to  symbol  names.  The case hack is a hexadecimal number appended to
+ the symbol name, with a bit being set for  each  upper  case  letter.
+ Symbols with all lower case, or symbols that have a dollar sign ("$")
+ are not case hacked.  There  are  times  that  this  is  undesirable,
+ namely  when  you  wish  to  link  your program against a precompiled
+ library which was compiled with a non-GNU-C compiler.  X-windows  (or
+ DECWindows)   is  an  example  of  this.   In  these  instances,  the
+ /NOCASE_HACK switch should be used.
+
+ If you require case hacking in some cases, but not  in  others  (i.e.
+ Libg++  with  DECWindows),  then it is recommended that you develop a
+ header file which will define all mixed case  functions  that  should
+ not have a case hack as the lower case equivalents.
+
+     GNU-C does not provide  the  globaldef  and  globalref  mechanism
+ which  is  used  by VAX-C to coerce the VMS linker to include certain
+ object modules from a library.  There are assembler hacks, which  are
+ available  to  the  user  through  the macros defined in gnu_hacks.h,
+ which effectively give you the ability to  perform  these  functions.
+ While  not  syntactically  identical,  they  do  provide  most of the
+ functionality.
+
+ Note that globaldefs of enums is not supported in the way that it  is
+ under  VAX-C.  This can be easily simulated, however, by globaldefing
+ an integer variable, and then globalvaluing  all  of  the  enumerated
+ states.
+
+ Furthermore, the way that globalvalue is currently  implemented,  the
+ data type of the globalvalue variable is seen to the compiler to be a
+ pointer to the data type that you  specify.   This  is  necessary  in
+ order   to  make  the  compiler  correctly  address  the  globalvalue

+@chapter Compile C, C++, or Objective C
+
+@cindex Objective C
+The C, C++, and Objective C versions of the compiler are integrated; the
+GNU C compiler can compile programs written in C, C++, or Objective C.
+
+@cindex GCC
+``GCC'' is a common shorthand term for the GNU C compiler.  This is both
+the most general name for the compiler, and the name used when the
+emphasis is on compiling C programs.
+
+@cindex C++
+@cindex G++
+When referring to C++ compilation, it is usual to call the compiler
+``G++''.  Since there is only one compiler, it is also accurate to call
+it ``GCC'' no matter what the language context; however, the term
+``G++'' is more useful when the emphasis is on compiling C++ programs.
+
+We use the name ``GNU CC'' to refer to the compilation system as a
+whole, and more specifically to the language-independent part of the
+compiler.  For example, we refer to the optimization options as
+affecting the behavior of ``GNU CC'' or sometimes just ``the compiler''.
+
+Front ends for other languages, such as Ada 9X, Fortran, Modula-3, and
+Pascal, are under development.  These front-ends, like that for C++, are
+built in subdirectories of GNU CC and link to it.  The result is an
+integrated compiler that can compile programs written in C, C++,
+Objective C, or any of the languages for which you have installed front
+ends.
+
+In this manual, we only discuss the options for the C, Objective-C, and
+C++ compilers and those of the GNU CC core.  Consult the documentation
+of the other front ends for the options to use when compiling programs
+written in other languages.
+
+@cindex compiler compared to C++ preprocessor
+@cindex intermediate C version, nonexistent
+@cindex C intermediate output, nonexistent
+G++ is a @emph{compiler}, not merely a preprocessor.  G++ builds object
+code directly from your C++ program source.  There is no intermediate C
+version of the program.  (By contrast, for example, some other
+implementations use a program that generates a C program from your C++
+source.)  Avoiding an intermediate C representation of the program means
+that you get better object code, and better debugging information.  The
+GNU debugger, GDB, works with this information in the object code to
+give you comprehensive C++ source-level editing capabilities
+(@pxref{C,,C and C++,gdb.info, Debugging with GDB}).
+
+@c FIXME!  Someone who knows something about Objective C ought to put in
+@c a paragraph or two about it here, and move the index entry down when
+@c there is more to point to than the general mention in the 1st par.

+
+This section describes known problems that affect users of GNU CC.  Most
+of these are not GNU CC bugs per se---if they were, we would fix them.
+But the result for a user may be like the result of a bug.
+
+Some of these problems are due to bugs in other software, some are
+missing features that are too much work to add, and some are places
+where people's opinions differ as to what is best.

+
+@node Actual Bugs
+@section Actual Bugs We Haven't Fixed Yet
+
+@itemize @bullet
+@item
+The @code{fixincludes} script interacts badly with automounters; if the
+directory of system header files is automounted, it tends to be
+unmounted while @code{fixincludes} is running.  This would seem to be a
+bug in the automounter.  We don't know any good way to work around it.
+
+@item
+The @code{fixproto} script will sometimes add prototypes for the
+@code{sigsetjmp} and @code{siglongjmp} functions that reference the
+@code{jmp_buf} type before that type is defined.  To work around this,
+edit the offending file and place the typedef in front of the
+prototypes.
+
+@item
+There are several obscure case of mis-using struct, union, and
+enum tags that are not detected as errors by the compiler.
+
+@item
+When @samp{-pedantic-errors} is specified, GNU C will incorrectly give
+an error message when a function name is specified in an expression
+involving the comma operator.
+
+@item
+Loop unrolling doesn't work properly for certain C++ programs.  This is
+a bug in the C++ front end.  It sometimes emits incorrect debug info, and
+the loop unrolling code is unable to recover from this error.
+@end itemize
+
+@node Installation Problems
+@section Installation Problems
+
+This is a list of problems (and some apparent problems which don't
+really mean anything is wrong) that show up during installation of GNU
+CC.
+
+@itemize @bullet
+@item
+On certain systems, defining certain environment variables such as
+@code{CC} can interfere with the functioning of @code{make}.
+
+@item
+If you encounter seemingly strange errors when trying to build the
+compiler in a directory other than the source directory, it could be
+because you have previously configured the compiler in the source
+directory.  Make sure you have done all the necessary preparations.
+@xref{Other Dir}.
+
+@item
+If you build GNU CC on a BSD system using a directory stored in a System
+V file system, problems may occur in running @code{fixincludes} if the
+System V file system doesn't support symbolic links.  These problems
+result in a failure to fix the declaration of @code{size_t} in
+@file{sys/types.h}.  If you find that @code{size_t} is a signed type and
+that type mismatches occur, this could be the cause.
+
+The solution is not to use such a directory for building GNU CC.
+
+@item
+In previous versions of GNU CC, the @code{gcc} driver program looked for
+@code{as} and @code{ld} in various places; for example, in files
+beginning with @file{/usr/local/lib/gcc-}.  GNU CC version 2 looks for
+them in the directory
+@file{/usr/local/lib/gcc-lib/@var{target}/@var{version}}.
+
+Thus, to use a version of @code{as} or @code{ld} that is not the system
+default, for example @code{gas} or GNU @code{ld}, you must put them in
+that directory (or make links to them from that directory).
+
+@item
+Some commands executed when making the compiler may fail (return a
+non-zero status) and be ignored by @code{make}.  These failures, which
+are often due to files that were not found, are expected, and can safely
+be ignored.
+
+@item
+It is normal to have warnings in compiling certain files about
+unreachable code and about enumeration type clashes.  These files' names
+begin with @samp{insn-}.  Also, @file{real.c} may get some warnings that
+you can ignore.
+
+@item
+Sometimes @code{make} recompiles parts of the compiler when installing
+the compiler.  In one case, this was traced down to a bug in
+@code{make}.  Either ignore the problem or switch to GNU Make.
+
+@item
+If you have installed a program known as purify, you may find that it
+causes errors while linking @code{enquire}, which is part of building
+GNU CC.  The fix is to get rid of the file @code{real-ld} which purify
+installs---so that GNU CC won't try to use it.
+
+@item
+On Linux SLS 1.01, there is a problem with @file{libc.a}: it does not
+contain the obstack functions.  However, GNU CC assumes that the obstack
+functions are in @file{libc.a} when it is the GNU C library.  To work
+around this problem, change the @code{__GNU_LIBRARY__} conditional
+around line 31 to @samp{#if 1}.
+
+@item
+On some 386 systems, building the compiler never finishes because
+@code{enquire} hangs due to a hardware problem in the motherboard---it
+reports floating point exceptions to the kernel incorrectly.  You can
+install GNU CC except for @file{float.h} by patching out the command to
+run @code{enquire}.  You may also be able to fix the problem for real by
+getting a replacement motherboard.  This problem was observed in
+Revision E of the Micronics motherboard, and is fixed in Revision F.
+It has also been observed in the MYLEX MXA-33 motherboard.
+
+If you encounter this problem, you may also want to consider removing
+the FPU from the socket during the compilation.  Alternatively, if you
+are running SCO Unix, you can reboot and force the FPU to be ignored.
+To do this, type @samp{hd(40)unix auto ignorefpu}.
+
+@item
+On some 386 systems, GNU CC crashes trying to compile @file{enquire.c}.
+This happens on machines that don't have a 387 FPU chip.  On 386
+machines, the system kernel is supposed to emulate the 387 when you
+don't have one.  The crash is due to a bug in the emulator.
+
+One of these systems is the Unix from Interactive Systems: 386/ix.
+On this system, an alternate emulator is provided, and it does work.
+To use it, execute this command as super-user:
+
+@example
+ln /etc/emulator.rel1 /etc/emulator
+@end example
+
+@noindent
+and then reboot the system.  (The default emulator file remains present
+under the name @file{emulator.dflt}.)
+
+Try using @file{/etc/emulator.att}, if you have such a problem on the
+SCO system.
+
+Another system which has this problem is Esix.  We don't know whether it
+has an alternate emulator that works.
+
+On NetBSD 0.8, a similar problem manifests itself as these error messages:
+
+@example
+enquire.c: In function `fprop':
+enquire.c:2328: floating overflow
+@end example
+
+@item
+On SCO systems, when compiling GNU CC with the system's compiler,
+do not use @samp{-O}.  Some versions of the system's compiler miscompile
+GNU CC with @samp{-O}.
+
+@cindex @code{genflags}, crash on Sun 4
+@item
+Sometimes on a Sun 4 you may observe a crash in the program
+@code{genflags} or @code{genoutput} while building GNU CC.  This is said to
+be due to a bug in @code{sh}.  You can probably get around it by running
+@code{genflags} or @code{genoutput} manually and then retrying the
+@code{make}.
+
+@item
+On Solaris 2, executables of GNU CC version 2.0.2 are commonly
+available, but they have a bug that shows up when compiling current
+versions of GNU CC: undefined symbol errors occur during assembly if you
+use @samp{-g}.
+
+The solution is to compile the current version of GNU CC without
+@samp{-g}.  That makes a working compiler which you can use to recompile
+with @samp{-g}.
+
+@item
+Solaris 2 comes with a number of optional OS packages.  Some of these
+packages are needed to use GNU CC fully.  If you did not install all
+optional packages when installing Solaris, you will need to verify that
+the packages that GNU CC needs are installed.
+
+To check whether an optional package is installed, use
+the @code{pkginfo} command.  To add an optional package, use the
+@code{pkgadd} command.  For further details, see the Solaris
+documentation.
+
+For Solaris 2.0 and 2.1, GNU CC needs six packages: @samp{SUNWarc},
+@samp{SUNWbtool}, @samp{SUNWesu}, @samp{SUNWhea}, @samp{SUNWlibm}, and
+@samp{SUNWtoo}.
+
+For Solaris 2.2, GNU CC needs an additional seventh package: @samp{SUNWsprot}.
+
+@item
+On Solaris 2, trying to use the linker and other tools in
+@file{/usr/ucb} to install GNU CC has been observed to cause trouble.
+For example, the linker may hang indefinitely.  The fix is to remove
+@file{/usr/ucb} from your @code{PATH}.
+
+@item
+If you use the 1.31 version of the MIPS assembler (such as was shipped
+with Ultrix 3.1), you will need to use the -fno-delayed-branch switch
+when optimizing floating point code.  Otherwise, the assembler will
+complain when the GCC compiler fills a branch delay slot with a
+floating point instruction, such as @code{add.d}.
+
+@item
+If on a MIPS system you get an error message saying ``does not have gp
+sections for all it's [sic] sectons [sic]'', don't worry about it.  This
+happens whenever you use GAS with the MIPS linker, but there is not
+really anything wrong, and it is okay to use the output file.  You can
+stop such warnings by installing the GNU linker.
+
+It would be nice to extend GAS to produce the gp tables, but they are
+optional, and there should not be a warning about their absence.
+
+@item
+In Ultrix 4.0 on the MIPS machine, @file{stdio.h} does not work with GNU
+CC at all unless it has been fixed with @code{fixincludes}.  This causes
+problems in building GNU CC.  Once GNU CC is installed, the problems go
+away.
+
+To work around this problem, when making the stage 1 compiler, specify
+this option to Make:
+
+@example
+GCC_FOR_TARGET="./xgcc -B./ -I./include"
+@end example
+
+When making stage 2 and stage 3, specify this option:
+
+@example
+CFLAGS="-g -I./include"
+@end example
+
+@item
+Users have reported some problems with version 2.0 of the MIPS
+compiler tools that were shipped with Ultrix 4.1.  Version 2.10
+which came with Ultrix 4.2 seems to work fine.
+
+Users have also reported some problems with version 2.20 of the
+MIPS compiler tools that were shipped with RISC/os 4.x.  The earlier
+version 2.11 seems to work fine.
+
+@item
+Some versions of the MIPS linker will issue an assertion failure
+when linking code that uses @code{alloca} against shared
+libraries on RISC-OS 5.0, and DEC's OSF/1 systems.  This is a bug
+in the linker, that is supposed to be fixed in future revisions.
+To protect against this, GNU CC passes @samp{-non_shared} to the
+linker unless you pass an explicit @samp{-shared} or
+@samp{-call_shared} switch.
+
+@item
+On System V release 3, you may get this error message
+while linking:
+
+@smallexample
+ld fatal: failed to write symbol name @var{something}
+ in strings table for file @var{whatever}
+@end smallexample
+
+This probably indicates that the disk is full or your ULIMIT won't allow
+the file to be as large as it needs to be.
+
+This problem can also result because the kernel parameter @code{MAXUMEM}
+is too small.  If so, you must regenerate the kernel and make the value
+much larger.  The default value is reported to be 1024; a value of 32768
+is said to work.  Smaller values may also work.
+
+@item
+On System V, if you get an error like this,
+
+@example
+/usr/local/lib/bison.simple: In function `yyparse':
+/usr/local/lib/bison.simple:625: virtual memory exhausted
+@end example
+
+@noindent
+that too indicates a problem with disk space, ULIMIT, or @code{MAXUMEM}.
+
+@item
+Current GNU CC versions probably do not work on version 2 of the NeXT
+operating system.
+

+The bug is not really in the assembler, but in the shared library
+version of the function ``cvtnum(3c)''.  The bug on ``cvtnum(3c)'' is
+SR#4701-078451.  Anyway, the attached assembler uses the archive

+@node Cross-Compiler Problems
+@section Cross-Compiler Problems
+
+You may run into problems with cross compilation on certain machines,
+for several reasons.
+
+@itemize @bullet
+@item
+Cross compilation can run into trouble for certain machines because
+some target machines' assemblers require floating point numbers to be
+written as @emph{integer} constants in certain contexts.
+
+The compiler writes these integer constants by examining the floating
+point value as an integer and printing that integer, because this is
+simple to write and independent of the details of the floating point
+representation.  But this does not work if the compiler is running on
+a different machine with an incompatible floating point format, or
+even a different byte-ordering.
+
+In addition, correct constant folding of floating point values
+requires representing them in the target machine's format.
+(The C standard does not quite require this, but in practice
+it is the only way to win.)
+
+It is now possible to overcome these problems by defining macros such
+as @code{REAL_VALUE_TYPE}.  But doing so is a substantial amount of
+work for each target machine.

+
+This section lists various difficulties encountered in using GNU C or
+GNU C++ together with other compilers or with the assemblers, linkers,
+libraries and debuggers on certain systems.
+
+@itemize @bullet
+@item
+Objective C does not work on the RS/6000.
+
+@item
+GNU C++ does not do name mangling in the same way as other C++
+compilers.  This means that object files compiled with one compiler
+cannot be used with another.
+
+This effect is intentional, to protect you from more subtle problems.
+Compilers differ as to many internal details of C++ implementation,
+including: how class instances are laid out, how multiple inheritance is
+implemented, and how virtual function calls are handled.  If the name
+encoding were made the same, your programs would link against libraries
+provided from other compilers---but the programs would then crash when
+run.  Incompatible libraries are then detected at link time, rather than
+at run time.
+
+@item
+Older GDB versions sometimes fail to read the output of GNU CC version
+2.  If you have trouble, get GDB version 4.4 or later.
+
+@item
+@cindex DBX
+DBX rejects some files produced by GNU CC, though it accepts similar
+constructs in output from PCC.  Until someone can supply a coherent
+description of what is valid DBX input and what is not, there is
+nothing I can do about these problems.  You are on your own.
+
+@item
+The GNU assembler (GAS) does not support PIC.  To generate PIC code, you
+must use some other assembler, such as @file{/bin/as}.
+
+@item
+On some BSD systems, including some versions of Ultrix, use of profiling
+causes static variable destructors (currently used only in C++) not to
+be run.
+
+@item
+Use of @samp{-I/usr/include} may cause trouble.
+
+Many systems come with header files that won't work with GNU CC unless
+corrected by @code{fixincludes}.  The corrected header files go in a new
+directory; GNU CC searches this directory before @file{/usr/include}.
+If you use @samp{-I/usr/include}, this tells GNU CC to search
+@file{/usr/include} earlier on, before the corrected headers.  The
+result is that you get the uncorrected header files.
+
+Instead, you should use these options (when compiling C programs):
+
+@smallexample
+-I/usr/local/lib/gcc-lib/@var{target}/@var{version}/include -I/usr/include
+@end smallexample
+
+For C++ programs, GNU CC also uses a special directory that defines C++
+interfaces to standard C subroutines.  This directory is meant to be
+searched @emph{before} other standard include directories, so that it
+takes precedence.  If you are compiling C++ programs and specifying
+include directories explicitly, use this option first, then the two
+options above:
+
+@example
+-I/usr/local/lib/g++-include
+@end example
+
+@ignore
+@cindex @code{vfork}, for the Sun-4
+@item
+There is a bug in @code{vfork} on the Sun-4 which causes the registers
+of the child process to clobber those of the parent.  Because of this,
+programs that call @code{vfork} are likely to lose when compiled
+optimized with GNU CC when the child code alters registers which contain
+C variables in the parent.  This affects variables which are live in the
+parent across the call to @code{vfork}.
+
+If you encounter this, you can work around the problem by declaring
+variables @code{volatile} in the function that calls @code{vfork}, until
+the problem goes away, or by not declaring them @code{register} and not
+using @samp{-O} for those source files.
+@end ignore
+
+@item
+On some SGI systems, when you use @samp{-lgl_s} as an option,
+it gets translated magically to @samp{-lgl_s -lX11_s -lc_s}.
+Naturally, this does not happen when you use GNU CC.
+You must specify all three options explicitly.
+
+@item
+On a Sparc, GNU CC aligns all values of type @code{double} on an 8-byte
+boundary, and it expects every @code{double} to be so aligned.  The Sun
+compiler usually gives @code{double} values 8-byte alignment, with one
+exception: function arguments of type @code{double} may not be aligned.
+
+As a result, if a function compiled with Sun CC takes the address of an
+argument of type @code{double} and passes this pointer of type
+@code{double *} to a function compiled with GNU CC, dereferencing the
+pointer may cause a fatal signal.
+
+One way to solve this problem is to compile your entire program with GNU
+CC.  Another solution is to modify the function that is compiled with
+Sun CC to copy the argument into a local variable; local variables
+are always properly aligned.  A third solution is to modify the function
+that uses the pointer to dereference it via the following function
+@code{access_double} instead of directly with @samp{*}:
+
+@smallexample
+inline double
+access_double (double *unaligned_ptr)
+@{
+  union d2i @{ double d; int i[2]; @};
+
+  union d2i *p = (union d2i *) unaligned_ptr;
+  union d2i u;
+
+  u.i[0] = p->i[0];
+  u.i[1] = p->i[1];
+
+  return u.d;
+@}
+@end smallexample
+
+@noindent
+Storing into the pointer can be done likewise with the same union.
+
+@item
+On Solaris, the @code{malloc} function in the @file{libmalloc.a} library
+may allocate memory that is only 4 byte aligned.  Since GNU CC on the
+Sparc assumes that doubles are 8 byte aligned, this may result in a
+fatal signal if doubles are stored in memory allocated by the
+@file{libmalloc.a} library.
+
+The solution is to not use the @file{libmalloc.a} library.  Use instead
+@code{malloc} and related functions from @file{libc.a}; they do not have
+this problem.
+
+@item
+Sun forgot to include a static version of @file{libdl.a} with some
+versions of SunOS (mainly 4.1).  This results in undefined symbols when
+linking static binaries (that is, if you use @samp{-static}).  If you
+see undefined symbols @code{_dlclose}, @code{_dlsym} or @code{_dlopen}
+when linking, compile and link against the file
+@file{mit/util/misc/dlsym.c} from the MIT version of X windows.
+
+@item
+The 128-bit long double format that the Sparc port supports currently
+works by using the architecturally defined quad-word floating point
+instructions.  Since there is no hardware that supports these
+instructions they must be emulated by the operating system.  Long
+doubles do not work in Sun OS versions 4.0.3 and earlier, because the
+kernel emulator uses an obsolete and incompatible format.  Long doubles
+do not work in Sun OS version 4.1.1 due to a problem in a Sun library.
+Long doubles do work on Sun OS versions 4.1.2 and higher, but GNU CC
+does not enable them by default.  Long doubles appear to work in Sun OS
+5.x (Solaris 2.x).
+
+@item
+On HP-UX version 9.01 on the HP PA, the HP compiler @code{cc} does not
+compile GNU CC correctly.  We do not yet know why.  However, GNU CC
+compiled on earlier HP-UX versions works properly on HP-UX 9.01 and can
+compile itself properly on 9.01.
+
+@item
+On the HP PA machine, ADB sometimes fails to work on functions compiled
+with GNU CC.  Specifically, it fails to work on functions that use
+@code{alloca} or variable-size arrays.  This is because GNU CC doesn't
+generate HP-UX unwind descriptors for such functions.  It may even be
+impossible to generate them.
+
+@item
+Debugging (@samp{-g}) is not supported on the HP PA machine, unless you use
+the preliminary GNU tools (@pxref{Installation}).
+
+@item
+Taking the address of a label may generate errors from the HP-UX
+PA assembler.  GAS for the PA does not have this problem.
+
+@item
+Using floating point parameters for indirect calls to static functions
+will not work when using the HP assembler.  There simply is no way for GCC
+to specify what registers hold arguments for static functions when using
+the HP assembler.  GAS for the PA does not have this problem.
+
+@item
+In extremely rare cases involving some very large functions you may
+receive errors from the HP linker complaining about an out of bounds
+unconditional branch offset.  This used to occur more often in previous
+versions of GNU CC, but is now exceptionally rare.  If you should run
+into it, you can work around by making your function smaller.
+
+@item
+GNU CC compiled code sometimes emits warnings from the HP-UX assembler of
+the form:
+

+
+These warnings are harmless and can be safely ignored.
+
+@item
+The current version of the assembler (@file{/bin/as}) for the RS/6000
+has certain problems that prevent the @samp{-g} option in GCC from
+working.  Note that @file{Makefile.in} uses @samp{-g} by default when
+compiling @file{libgcc2.c}.
+
+IBM has produced a fixed version of the assembler.  The upgraded
+assembler unfortunately was not included in any of the AIX 3.2 update
+PTF releases (3.2.2, 3.2.3, or 3.2.3e).  Users of AIX 3.1 should request
+PTF U403044 from IBM and users of AIX 3.2 should request PTF U416277.
+See the file @file{README.RS6000} for more details on these updates.
+
+You can test for the presense of a fixed assembler by using the
+command
+
+@smallexample
+as -u < /dev/null
+@end smallexample
+
+@noindent
+If the command exits normally, the assembler fix already is installed.
+If the assembler complains that "-u" is an unknown flag, you need to
+order the fix.
+
+@item
+On the IBM RS/6000, compiling code of the form
+
+@smallexample
+extern int foo;
+
+@dots{} foo @dots{}
+
+static int foo;
+@end smallexample
+
+@noindent
+will cause the linker to report an undefined symbol @code{foo}.
+Although this behavior differs from most other systems, it is not a
+bug because redefining an @code{extern} variable as @code{static}
+is undefined in ANSI C.
+
+@item
+AIX on the RS/6000 provides support (NLS) for environments outside of
+the United States.  Compilers and assemblers use NLS to support
+locale-specific representations of various objects including
+floating-point numbers ("." vs "," for separating decimal fractions).
+There have been problems reported where the library linked with GCC does
+not produce the same floating-point formats that the assembler accepts.
+If you have this problem, set the LANG environment variable to "C" or
+"En_US".
+
+@item
+Even if you specify @samp{-fdollars-in-identifiers},
+you cannot successfully use @samp{$} in identifiers on the RS/6000 due
+to a restriction in the IBM assembler.  GAS supports these
+identifiers.
+
+@item
+On the RS/6000, XLC version 1.3.0.0 will miscompile @file{jump.c}.  XLC
+version 1.3.0.1 or later fixes this problem.  You can obtain XLC-1.3.0.2
+by requesting PTF 421749 from IBM.
+
+@item
+There is an assembler bug in versions of DG/UX prior to 5.4.2.01 that
+occurs when the @samp{fldcr} instruction is used.  GNU CC uses
+@samp{fldcr} on the 88100 to serialize volatile memory references.  Use
+the option @samp{-mno-serialize-volatile} if your version of the
+assembler has this bug.
+
+@item
+On VMS, GAS versions 1.38.1 and earlier may cause spurious warning
+messages from the linker.  These warning messages complain of mismatched
+psect attributes.  You can ignore them.  @xref{VMS Install}.
+
+@item
+On NewsOS version 3, if you include both of the files @file{stddef.h}
+and @file{sys/types.h}, you get an error because there are two typedefs
+of @code{size_t}.  You should change @file{sys/types.h} by adding these
+lines around the definition of @code{size_t}:

+
+@cindex Alliant

+and unions is unusual, and is not compatible with GNU CC no matter
+what options are used.
+
+@cindex RT PC
+@cindex IBM RT PC
+@item
+On the IBM RT PC, the MetaWare HighC compiler (hc) uses a different
+convention for structure and union returning.  Use the option
+@samp{-mhc-struct-return} to tell GNU CC to use a convention compatible
+with it.
+
+@cindex Vax calling convention
+@cindex Ultrix calling convention
+@item
+On Ultrix, the Fortran compiler expects registers 2 through 5 to be saved
+by function calls.  However, the C compiler uses conventions compatible
+with BSD Unix: registers 2 through 5 may be clobbered by function calls.
+
+GNU CC uses the same convention as the Ultrix C compiler.  You can use
+these options to produce code compatible with the Fortran compiler:
+
+@smallexample
+-fcall-saved-r2 -fcall-saved-r3 -fcall-saved-r4 -fcall-saved-r5
+@end smallexample
+
+@item
+On the WE32k, you may find that programs compiled with GNU CC do not
+work with the standard shared C library.  You may need to link with
+the ordinary C compiler.  If you do so, you must specify the following
+options:
+
+@smallexample
+-L/usr/local/lib/gcc-lib/we32k-att-sysv/2.7.1 -lgcc -lc_s
+@end smallexample
+
+The first specifies where to find the library @file{libgcc.a}
+specified with the @samp{-lgcc} option.
+
+GNU CC does linking by invoking @code{ld}, just as @code{cc} does, and
+there is no reason why it @emph{should} matter which compilation program
+you use to invoke @code{ld}.  If someone tracks this problem down,
+it can probably be fixed easily.
+
+@item
+On the Alpha, you may get assembler errors about invalid syntax as a
+result of floating point constants.  This is due to a bug in the C
+library functions @code{ecvt}, @code{fcvt} and @code{gcvt}.  Given valid
+floating point numbers, they sometimes print @samp{NaN}.
+
+@item
+On Irix 4.0.5F (and perhaps in some other versions), an assembler bug
+sometimes reorders instructions incorrectly when optimization is turned
+on.  If you think this may be happening to you, try using the GNU
+assembler; GAS version 2.1 supports ECOFF on Irix.
+
+Or use the @samp{-noasmopt} option when you compile GNU CC with itself,
+and then again when you compile your program.  (This is a temporary
+kludge to turn off assembler optimization on Irix.)  If this proves to
+be what you need, edit the assembler spec in the file @file{specs} so
+that it unconditionally passes @samp{-O0} to the assembler, and never
+passes @samp{-O2} or @samp{-O3}.

+On various 386 Unix systems derived from System V, including SCO, ISC,
+and ESIX, you may get error messages about running out of virtual memory

+
+You can prevent this problem by linking GNU CC with the GNU malloc
+(which thus replaces the malloc that comes with the system).  GNU malloc

+@node Incompatibilities
+@section Incompatibilities of GNU CC
+@cindex incompatibilities of GNU CC
+
+There are several noteworthy incompatibilities between GNU C and most
+existing (non-ANSI) versions of C.  The @samp{-traditional} option
+eliminates many of these incompatibilities, @emph{but not all}, by
+telling GNU C to behave like the other C compilers.
+
+@itemize @bullet
+@cindex string constants
+@cindex read-only strings
+@cindex shared strings
+@item
+GNU CC normally makes string constants read-only.  If several
+identical-looking string constants are used, GNU CC stores only one
+copy of the string.
+
+@cindex @code{mktemp}, and constant strings
+One consequence is that you cannot call @code{mktemp} with a string
+constant argument.  The function @code{mktemp} always alters the
+string its argument points to.
+
+@cindex @code{sscanf}, and constant strings
+@cindex @code{fscanf}, and constant strings
+@cindex @code{scanf}, and constant strings
+Another consequence is that @code{sscanf} does not work on some systems
+when passed a string constant as its format control string or input.
+This is because @code{sscanf} incorrectly tries to write into the string
+constant.  Likewise @code{fscanf} and @code{scanf}.
+
+The best solution to these problems is to change the program to use
+@code{char}-array variables with initialization strings for these
+purposes instead of string constants.  But if this is not possible,
+you can use the @samp{-fwritable-strings} flag, which directs GNU CC
+to handle string constants the same way most C compilers do.
+@samp{-traditional} also has this effect, among others.
+
+@item
+@code{-2147483648} is positive.
+
+This is because 2147483648 cannot fit in the type @code{int}, so
+(following the ANSI C rules) its data type is @code{unsigned long int}.
+Negating this value yields 2147483648 again.
+
+@item
+GNU CC does not substitute macro arguments when they appear inside of
+string constants.  For example, the following macro in GNU CC
+
+@example
+#define foo(a) "a"
+@end example
+
+@noindent
+will produce output @code{"a"} regardless of what the argument @var{a} is.
+
+The @samp{-traditional} option directs GNU CC to handle such cases
+(among others) in the old-fashioned (non-ANSI) fashion.
+
+@cindex @code{setjmp} incompatibilities
+@cindex @code{longjmp} incompatibilities
+@item
+When you use @code{setjmp} and @code{longjmp}, the only automatic
+variables guaranteed to remain valid are those declared
+@code{volatile}.  This is a consequence of automatic register
+allocation.  Consider this function:
+
+@example
+jmp_buf j;
+
+foo ()
+@{
+  int a, b;
+
+  a = fun1 ();
+  if (setjmp (j))
+    return a;
+
+  a = fun2 ();
+  /* @r{@code{longjmp (j)} may occur in @code{fun3}.} */
+  return a + fun3 ();
+@}
+@end example
+
+Here @code{a} may or may not be restored to its first value when the
+@code{longjmp} occurs.  If @code{a} is allocated in a register, then
+its first value is restored; otherwise, it keeps the last value stored
+in it.
+
+If you use the @samp{-W} option with the @samp{-O} option, you will
+get a warning when GNU CC thinks such a problem might be possible.
+
+The @samp{-traditional} option directs GNU C to put variables in
+the stack by default, rather than in registers, in functions that
+call @code{setjmp}.  This results in the behavior found in
+traditional C compilers.
+

+Programs that use preprocessing directives in the middle of macro

+@end example
+
+ANSI C does not permit such a construct.  It would make sense to support
+it when @samp{-traditional} is used, but it is too much work to
+implement.
+
+@cindex external declaration scope
+@cindex scope of external declarations
+@cindex declaration scope
+@item
+Declarations of external variables and functions within a block apply
+only to the block containing the declaration.  In other words, they
+have the same scope as any other declaration in the same place.
+
+In some other C compilers, a @code{extern} declaration affects all the
+rest of the file even if it happens within a block.
+
+The @samp{-traditional} option directs GNU C to treat all @code{extern}
+declarations as global, like traditional compilers.
+
+@item
+In traditional C, you can combine @code{long}, etc., with a typedef name,
+as shown here:
+
+@example
+typedef int foo;
+typedef long foo bar;
+@end example
+
+In ANSI C, this is not allowed: @code{long} and other type modifiers
+require an explicit @code{int}.  Because this criterion is expressed
+by Bison grammar rules rather than C code, the @samp{-traditional}
+flag cannot alter it.
+
+@cindex typedef names as function parameters
+@item
+PCC allows typedef names to be used as function parameters.  The
+difficulty described immediately above applies here too.
+
+@cindex whitespace
+@item
+PCC allows whitespace in the middle of compound assignment operators
+such as @samp{+=}.  GNU CC, following the ANSI standard, does not
+allow this.  The difficulty described immediately above applies here
+too.
+
+@cindex apostrophes
+@cindex '
+@item
+GNU CC complains about unterminated character constants inside of
+preprocessing conditionals that fail.  Some programs have English
+comments enclosed in conditionals that are guaranteed to fail; if these
+comments contain apostrophes, GNU CC will probably report an error.  For
+example, this code would produce an error:
+
+@example
+#if 0
+You can't expect this to work.
+#endif
+@end example
+
+The best solution to such a problem is to put the text into an actual
+C comment delimited by @samp{/*@dots{}*/}.  However,
+@samp{-traditional} suppresses these error messages.
+
+@item
+Many user programs contain the declaration @samp{long time ();}.  In the
+past, the system header files on many systems did not actually declare
+@code{time}, so it did not matter what type your program declared it to
+return.  But in systems with ANSI C headers, @code{time} is declared to
+return @code{time_t}, and if that is not the same as @code{long}, then
+@samp{long time ();} is erroneous.
+
+The solution is to change your program to use @code{time_t} as the return
+type of @code{time}.
+
+@cindex @code{float} as function value type
+@item
+When compiling functions that return @code{float}, PCC converts it to
+a double.  GNU CC actually returns a @code{float}.  If you are concerned
+with PCC compatibility, you should declare your functions to return
+@code{double}; you might as well say what you mean.
+
+@cindex structures
+@cindex unions
+@item
+When compiling functions that return structures or unions, GNU CC
+output code normally uses a method different from that used on most
+versions of Unix.  As a result, code compiled with GNU CC cannot call
+a structure-returning function compiled with PCC, and vice versa.
+
+The method used by GNU CC is as follows: a structure or union which is
+1, 2, 4 or 8 bytes long is returned like a scalar.  A structure or union
+with any other size is stored into an address supplied by the caller
+(usually in a special, fixed register, but on some machines it is passed
+on the stack).  The machine-description macros @code{STRUCT_VALUE} and
+@code{STRUCT_INCOMING_VALUE} tell GNU CC where to pass this address.
+
+By contrast, PCC on most target machines returns structures and unions
+of any size by copying the data into an area of static storage, and then
+returning the address of that storage as if it were a pointer value.
+The caller must copy the data from that memory area to the place where
+the value is wanted.  GNU CC does not use this method because it is
+slower and nonreentrant.
+
+On some newer machines, PCC uses a reentrant convention for all
+structure and union returning.  GNU CC on most of these machines uses a
+compatible convention when returning structures and unions in memory,
+but still returns small structures and unions in registers.
+
+You can tell GNU CC to use a compatible convention for all structure and
+union returning with the option @samp{-fpcc-struct-return}.
+
+@cindex preprocessing tokens
+@cindex preprocessing numbers
+@item
+GNU C complains about program fragments such as @samp{0x74ae-0x4000}
+which appear to be two hexadecimal constants separated by the minus
+operator.  Actually, this string is a single @dfn{preprocessing token}.
+Each such token must correspond to one token in C.  Since this does not,
+GNU C prints an error message.  Although it may appear obvious that what
+is meant is an operator and two values, the ANSI C standard specifically
+requires that this be treated as erroneous.
+
+A @dfn{preprocessing token} is a @dfn{preprocessing number} if it
+begins with a digit and is followed by letters, underscores, digits,
+periods and @samp{e+}, @samp{e-}, @samp{E+}, or @samp{E-} character
+sequences.
+
+To make the above program fragment valid, place whitespace in front of
+the minus sign.  This whitespace will end the preprocessing number.

+@node Fixed Headers
+@section Fixed Header Files
+
+GNU CC needs to install corrected versions of some system header files.
+This is because most target systems have some header files that won't
+work with GNU CC unless they are changed.  Some have bugs, some are
+incompatible with ANSI C, and some depend on special features of other
+compilers.
+
+Installing GNU CC automatically creates and installs the fixed header
+files, by running a program called @code{fixincludes} (or for certain
+targets an alternative such as @code{fixinc.svr4}).  Normally, you
+don't need to pay attention to this.  But there are cases where it
+doesn't do the right thing automatically.
+
+@itemize @bullet
+@item
+If you update the system's header files, such as by installing a new
+system version, the fixed header files of GNU CC are not automatically
+updated.  The easiest way to update them is to reinstall GNU CC.  (If
+you want to be clever, look in the makefile and you can find a
+shortcut.)
+
+@item
+On some systems, in particular SunOS 4, header file directories contain
+machine-specific symbolic links in certain places.  This makes it
+possible to share most of the header files among hosts running the
+same version of SunOS 4 on different machine models.
+
+The programs that fix the header files do not understand this special
+way of using symbolic links; therefore, the directory of fixed header
+files is good only for the machine model used to build it.
+
+In SunOS 4, only programs that look inside the kernel will notice the
+difference between machine models.  Therefore, for most purposes, you
+need not be concerned about this.
+
+It is possible to make separate sets of fixed header files for the
+different machine models, and arrange a structure of symbolic links so
+as to use the proper set, but you'll have to do this by hand.
+
+@item
+On Lynxos, GNU CC by default does not fix the header files.  This is
+because bugs in the shell cause the @code{fixincludes} script to fail.
+
+This means you will encounter problems due to bugs in the system header
+files.  It may be no comfort that they aren't GNU CC's fault, but it
+does mean that there's nothing for us to do about them.

+
+@node Standard Libraries
+@section Standard Libraries
+
+GNU CC by itself attempts to be what the ISO/ANSI C standard calls a
+@dfn{conforming freestanding implementation}.  This means all ANSI
+C language features are available, as well as the contents of
+@file{float.h}, @file{limits.h}, @file{stdarg.h}, and
+@file{stddef.h}.  The rest of the C library is supplied by the
+vendor of the operating system.  If that C library doesn't conform to
+the C standards, then your programs might get warnings (especially when
+using @samp{-Wall}) that you don't expect.
+
+For example, the @code{sprintf} function on SunOS 4.1.3 returns
+@code{char *} while the C standard says that @code{sprintf} returns an
+@code{int}.  The @code{fixincludes} program could make the prototype for
+this function match the Standard, but that would be wrong, since the
+function will still return @code{char *}.
+
+If you need a Standard compliant library, then you need to find one, as
+GNU CC does not provide one.  The GNU C library (called @code{glibc})
+has been ported to a number of operating systems, and provides ANSI/ISO,
+POSIX, BSD and SystemV compatibility.  You could also ask your operating
+system vendor if newer libraries are available.

+Certain local variables aren't recognized by debuggers when you compile
+with optimization.
+
+This occurs because sometimes GNU CC optimizes the variable out of
+existence.  There is no way to tell the debugger how to compute the
+value such a variable ``would have had'', and it is not clear that would
+be desirable anyway.  So GNU CC simply does not mention the eliminated
+variable when it writes debugging information.
+
+You have to expect a certain amount of disagreement between the
+executable and your source code, when you use optimization.
+
+@cindex conflicting types
+@cindex scope of declaration
+@item
+Users often think it is a bug when GNU CC reports an error for code
+like this:
+
+@example
+int foo (struct mumble *);
+
+struct mumble @{ @dots{} @};
+
+int foo (struct mumble *x)
+@{ @dots{} @}
+@end example
+
+This code really is erroneous, because the scope of @code{struct
+mumble} in the prototype is limited to the argument list containing it.
+It does not refer to the @code{struct mumble} defined with file scope
+immediately below---they are two unrelated types with similar names in
+different scopes.
+
+But in the definition of @code{foo}, the file-scope type is used
+because that is available to be inherited.  Thus, the definition and
+the prototype do not match, and you get an error.
+
+This behavior may seem silly, but it's what the ANSI standard specifies.
+It is easy enough for you to make your code work by moving the
+definition of @code{struct mumble} above the prototype.  It's not worth
+being incompatible with ANSI C just to avoid an error for the example
+shown above.
+
+@item
+Accesses to bitfields even in volatile objects works by accessing larger
+objects, such as a byte or a word.  You cannot rely on what size of
+object is accessed in order to read or write the bitfield; it may even
+vary for a given bitfield according to the precise usage.
+
+If you care about controlling the amount of memory that is accessed, use
+volatile but do not use bitfields.

+GNU CC comes with shell scripts to fix certain known problems in system
+header files.  They install corrected copies of various header files in
+a special directory where only GNU CC will normally look for them.  The
+scripts adapt to various systems by searching all the system header
+files for the problem cases that we know about.
+
+If new system header files are installed, nothing automatically arranges
+to update the corrected header files.  You will have to reinstall GNU CC
+to fix the new header files.  More specifically, go to the build
+directory and delete the files @file{stmp-fixinc} and
+@file{stmp-headers}, and the subdirectory @code{include}; then do
+@samp{make install} again.
+
+@item
+@cindex floating point precision
+On 68000 and x86 systems, for instance, you can get paradoxical results
+if you test the precise values of floating point numbers.  For example,
+you can find that a floating point value which is not a NaN is not equal
+to itself.  This results from the fact that the floating point registers
+hold a few more bits of precision than fit in a @code{double} in memory.
+Compiled code moves values between memory and floating point registers
+at its convenience, and moving them into memory truncates them.
+
+You can partially avoid this problem by using the @samp{-ffloat-store}
+option (@pxref{Optimize Options}).
+
+@item
+On the MIPS, variable argument functions using @file{varargs.h}
+cannot have a floating point value for the first argument.  The
+reason for this is that in the absence of a prototype in scope,
+if the first argument is a floating point, it is passed in a
+floating point register, rather than an integer register.
+
+If the code is rewritten to use the ANSI standard @file{stdarg.h}
+method of variable arguments, and the prototype is in scope at
+the time of the call, everything will work fine.
+
+@item
+On the H8/300 and H8/300H, variable argument functions must be
+implemented using the ANSI standard @file{stdarg.h} method of
+variable arguments.  Furthermore, calls to functions using @file{stdarg.h}
+variable arguments must have a prototype for the called function
+in scope at the time of the call.

+@cindex C++ misunderstandings
+C++ is a complex language and an evolving one, and its standard definition
+(the ANSI C++ draft standard) is also evolving.  As a result,
+your C++ compiler may occasionally surprise you, even when its behavior is
+correct.  This section discusses some areas that frequently give rise to
+questions of this sort.
+
+@menu
+* Static Definitions::  Static member declarations are not definitions
+* Temporaries::         Temporaries may vanish before you expect

+
+@node Static Definitions
+@subsection Declare @emph{and} Define Static Members
+
+@cindex C++ static data, declaring and defining
+@cindex static data in C++, declaring and defining
+@cindex declaring static data in C++
+@cindex defining static data in C++
+When a class has static data members, it is not enough to @emph{declare}
+the static member; you must also @emph{define} it.  For example:
+
+@example
+class Foo
+@{
+  @dots{}
+  void method();
+  static int bar;
+@};
+@end example
+
+This declaration only establishes that the class @code{Foo} has an
+@code{int} named @code{Foo::bar}, and a member function named
+@code{Foo::method}.  But you still need to define @emph{both}
+@code{method} and @code{bar} elsewhere.  According to the draft ANSI
+standard, you must supply an initializer in one (and only one) source
+file, such as:
+
+@example
+int Foo::bar = 0;
+@end example
+
+Other C++ compilers may not correctly implement the standard behavior.
+As a result, when you switch to @code{g++} from one of these compilers,
+you may discover that a program that appeared to work correctly in fact
+does not conform to the standard: @code{g++} reports as undefined
+symbols any static data members that lack definitions.
+
+@node Temporaries
+@subsection Temporaries May Vanish Before You Expect
+
+@cindex temporaries, lifetime of
+@cindex portions of temporary objects, pointers to
+It is dangerous to use pointers or references to @emph{portions} of a
+temporary object.  The compiler may very well delete the object before
+you expect it to, leaving a pointer to garbage.  The most common place
+where this problem crops up is in classes like the libg++
+@code{String} class, that define a conversion function to type
+@code{char *} or @code{const char *}.  However, any class that returns
+a pointer to some internal structure is potentially subject to this
+problem.
+
+For example, a program may use a function @code{strfunc} that returns
+@code{String} objects, and another function @code{charfunc} that
+operates on pointers to @code{char}:
+
+@example
+String strfunc ();
+void charfunc (const char *);
+@end example
+
+@noindent
+In this situation, it may seem natural to write @w{@samp{charfunc
+(strfunc ());}} based on the knowledge that class @code{String} has an
+explicit conversion to @code{char} pointers.  However, what really
+happens is akin to @samp{charfunc (@w{strfunc ()}.@w{convert ()});},
+where the @code{convert} method is a function to do the same data
+conversion normally performed by a cast.  Since the last use of the
+temporary @code{String} object is the call to the conversion function,
+the compiler may delete that object before actually calling
+@code{charfunc}.  The compiler has no way of knowing that deleting the
+@code{String} object will invalidate the pointer.  The pointer then
+points to garbage, so that by the time @code{charfunc} is called, it
+gets an invalid argument.
+
+Code like this may run successfully under some other compilers,
+especially those that delete temporaries relatively late.  However, the
+GNU C++ behavior is also standard-conforming, so if your program depends
+on late destruction of temporaries it is not portable.
+
+If you think this is surprising, you should be aware that the ANSI C++
+committee continues to debate the lifetime-of-temporaries problem.
+
+For now, at least, the safe way to write such code is to give the
+temporary a name, which forces it to remain until the end of the scope of
+the name.  For example:
+
+@example
+String& tmp = strfunc ();
+charfunc (tmp);
+@end example
+
+@node Protoize Caveats
+@section Caveats of using @code{protoize}
+
+The conversion programs @code{protoize} and @code{unprotoize} can
+sometimes change a source file in a way that won't work unless you
+rearrange it.
+
+@itemize @bullet
+@item
+@code{protoize} can insert references to a type name or type tag before
+the definition, or in a file where they are not defined.
+
+If this happens, compiler error messages should show you where the new
+references are, so fixing the file by hand is straightforward.
+
+@item
+There are some C constructs which @code{protoize} cannot figure out.
+For example, it can't determine argument types for declaring a
+pointer-to-function variable; this you must do by hand.  @code{protoize}
+inserts a comment containing @samp{???} each time it finds such a
+variable; so you can find all such variables by searching for this
+string.  ANSI C does not require declaring the argument types of
+pointer-to-function types.
+
+@item
+Using @code{unprotoize} can easily introduce bugs.  If the program
+relied on prototypes to bring about conversion of arguments, these
+conversions will not take place in the program without prototypes.
+One case in which you can be sure @code{unprotoize} is safe is when
+you are removing prototypes that were made with @code{protoize}; if
+the program worked before without any prototypes, it will work again
+without them.
+
+You can find all the places where this problem might occur by compiling
+the program with the @samp{-Wconversion} option.  It prints a warning
+whenever an argument is converted.
+
+@item
+Both conversion programs can be confused if there are macro calls in and
+around the text to be converted.  In other words, the standard syntax
+for a declaration or definition must not result from expanding a macro.
+This problem is inherent in the design of C and cannot be fixed.  If
+only a few functions have confusing macro calls, you can easily convert
+them manually.
+
+@item
+@code{protoize} cannot get the argument types for a function whose
+definition was not actually compiled due to preprocessing conditionals.
+When this happens, @code{protoize} changes nothing in regard to such
+a function.  @code{protoize} tries to detect such instances and warn
+about them.
+
+You can generally work around this problem by using @code{protoize} step
+by step, each time specifying a different set of @samp{-D} options for
+compilation, until all of the functions have been converted.  There is
+no automatic way to verify that you have got them all, however.
+
+@item
+Confusion may result if there is an occasion to convert a function
+declaration or definition in a region of source code where there is more
+than one formal parameter list present.  Thus, attempts to convert code
+containing multiple (conditionally compiled) versions of a single
+function header (in the same vicinity) may not produce the desired (or
+expected) results.
+
+If you plan on converting source files which contain such code, it is
+recommended that you first make sure that each conditionally compiled
+region of source code which contains an alternative function header also
+contains at least one additional follower token (past the final right
+parenthesis of the function header).  This should circumvent the
+problem.
+
+@item
+@code{unprotoize} can become confused when trying to convert a function
+definition or declaration which contains a declaration for a
+pointer-to-function formal argument which has the same name as the
+function being defined or declared.  We recommand you avoid such choices
+of formal parameter names.
+
+@item
+You might also want to correct some of the indentation by hand and break
+long lines.  (The conversion programs don't write lines longer than
+eighty characters in any case.)

+@section Certain Changes We Don't Want to Make
+
+This section lists changes that people frequently request, but which
+we do not make because we think GNU CC is better without them.
+
+@itemize @bullet
+@item
+Checking the number and type of arguments to a function which has an
+old-fashioned definition and no prototype.
+
+Such a feature would work only occasionally---only for calls that appear
+in the same file as the called function, following the definition.  The
+only way to check all calls reliably is to add a prototype for the
+function.  But adding a prototype eliminates the motivation for this
+feature.  So the feature is not worthwhile.
+
+@item
+Warning about using an expression whose type is signed as a shift count.
+
+Shift count operands are probably signed more often than unsigned.
+Warning about this would cause far more annoyance than good.
+
+@item
+Warning about assigning a signed value to an unsigned variable.
+
+Such assignments must be very common; warning about them would cause
+more annoyance than good.
+
+@item
+Warning about unreachable code.
+
+It's very common to have unreachable code in machine-generated
+programs.  For example, this happens normally in some files of GNU C
+itself.
+
+@item
+Warning when a non-void function value is ignored.
+
+Coming as I do from a Lisp background, I balk at the idea that there is
+something dangerous about discarding a value.  There are functions that
+return values which some callers may find useful; it makes no sense to
+clutter the program with a cast to @code{void} whenever the value isn't
+useful.
+
+@item
+Assuming (for optimization) that the address of an external symbol is
+never zero.
+
+This assumption is false on certain systems when @samp{#pragma weak} is
+used.
+
+@item
+Making @samp{-fshort-enums} the default.
+
+This would cause storage layout to be incompatible with most other C
+compilers.  And it doesn't seem very important, given that you can get
+the same result in other ways.  The case where it matters most is when
+the enumeration-valued object is inside a structure, and in that case
+you can specify a field width explicitly.
+
+@item
+Making bitfields unsigned by default on particular machines where ``the
+ABI standard'' says to do so.
+
+The ANSI C standard leaves it up to the implementation whether a bitfield
+declared plain @code{int} is signed or not.  This in effect creates two
+alternative dialects of C.
+
+The GNU C compiler supports both dialects; you can specify the signed
+dialect with @samp{-fsigned-bitfields} and the unsigned dialect with
+@samp{-funsigned-bitfields}.  However, this leaves open the question of
+which dialect to use by default.
+
+Currently, the preferred dialect makes plain bitfields signed, because
+this is simplest.  Since @code{int} is the same as @code{signed int} in
+every other context, it is cleanest for them to be the same in bitfields
+as well.
+
+Some computer manufacturers have published Application Binary Interface
+standards which specify that plain bitfields should be unsigned.  It is
+a mistake, however, to say anything about this issue in an ABI.  This is
+because the handling of plain bitfields distinguishes two dialects of C.
+Both dialects are meaningful on every type of machine.  Whether a
+particular object file was compiled using signed bitfields or unsigned
+is of no concern to other object files, even if they access the same
+bitfields in the same data structures.
+
+A given program is written in one or the other of these two dialects.
+The program stands a chance to work on most any machine if it is
+compiled with the proper dialect.  It is unlikely to work at all if
+compiled with the wrong dialect.
+
+Many users appreciate the GNU C compiler because it provides an
+environment that is uniform across machines.  These users would be
+inconvenienced if the compiler treated plain bitfields differently on
+certain machines.
+
+Occasionally users write programs intended only for a particular machine
+type.  On these occasions, the users would benefit if the GNU C compiler
+were to support by default the same dialect as the other compilers on
+that machine.  But such applications are rare.  And users writing a
+program to run on more than one type of machine cannot possibly benefit
+from this kind of compatibility.
+
+This is why GNU CC does and will treat plain bitfields in the same
+fashion on all types of machines (by default).
+
+There are some arguments for making bitfields unsigned by default on all
+machines.  If, for example, this becomes a universal de facto standard,
+it would make sense for GNU CC to go along with it.  This is something
+to be considered in the future.
+
+(Of course, users strongly concerned about portability should indicate
+explicitly in each bitfield whether it is signed or not.  In this way,
+they write programs which have the same meaning in both C dialects.)
+
+@item
+Undefining @code{__STDC__} when @samp{-ansi} is not used.
+
+Currently, GNU CC defines @code{__STDC__} as long as you don't use
+@samp{-traditional}.  This provides good results in practice.
+
+Programmers normally use conditionals on @code{__STDC__} to ask whether
+it is safe to use certain features of ANSI C, such as function
+prototypes or ANSI token concatenation.  Since plain @samp{gcc} supports
+all the features of ANSI C, the correct answer to these questions is
+``yes''.
+
+Some users try to use @code{__STDC__} to check for the availability of
+certain library facilities.  This is actually incorrect usage in an ANSI
+C program, because the ANSI C standard says that a conforming
+freestanding implementation should define @code{__STDC__} even though it
+does not have the library facilities.  @samp{gcc -ansi -pedantic} is a
+conforming freestanding implementation, and it is therefore required to
+define @code{__STDC__}, even though it does not come with an ANSI C
+library.
+
+Sometimes people say that defining @code{__STDC__} in a compiler that
+does not completely conform to the ANSI C standard somehow violates the
+standard.  This is illogical.  The standard is a standard for compilers
+that claim to support ANSI C, such as @samp{gcc -ansi}---not for other
+compilers such as plain @samp{gcc}.  Whatever the ANSI C standard says
+is relevant to the design of plain @samp{gcc} without @samp{-ansi} only
+for pragmatic reasons, not as a requirement.
+
+@item
+Undefining @code{__STDC__} in C++.
+
+Programs written to compile with C++-to-C translators get the
+value of @code{__STDC__} that goes with the C compiler that is
+subsequently used.  These programs must test @code{__STDC__}
+to determine what kind of C preprocessor that compiler uses:
+whether they should concatenate tokens in the ANSI C fashion
+or in the traditional fashion.
+
+These programs work properly with GNU C++ if @code{__STDC__} is defined.
+They would not work otherwise.
+
+In addition, many header files are written to provide prototypes in ANSI
+C but not in traditional C.  Many of these header files can work without
+change in C++ provided @code{__STDC__} is defined.  If @code{__STDC__}
+is not defined, they will all fail, and will all need to be changed to
+test explicitly for C++ as well.
+
+@item
+Deleting ``empty'' loops.
+
+GNU CC does not delete ``empty'' loops because the most likely reason
+you would put one in a program is to have a delay.  Deleting them will
+not make real programs run any faster, so it would be pointless.
+
+It would be different if optimization of a nonempty loop could produce
+an empty one.  But this generally can't happen.
+
+@item
+Making side effects happen in the same order as in some other compiler.
+
+@cindex side effects, order of evaluation
+@cindex order of evaluation, side effects
+It is never safe to depend on the order of evaluation of side effects.
+For example, a function call like this may very well behave differently
+from one compiler to another:
+
+@example
+void func (int, int);
+
+int i = 2;
+func (i++, i++);
+@end example
+
+There is no guarantee (in either the C or the C++ standard language
+definitions) that the increments will be evaluated in any particular
+order.  Either increment might happen first.  @code{func} might get the
+arguments @samp{2, 3}, or it might get @samp{3, 2}, or even @samp{2, 2}.
+
+@item
+Not allowing structures with volatile fields in registers.
+
+Strictly speaking, there is no prohibition in the ANSI C standard
+against allowing structures with volatile fields in registers, but
+it does not seem to make any sense and is probably not what you wanted
+to do.  So the compiler will give an error message in this case.

+@cindex warnings vs errors
+@cindex messages, warning and error
+The GNU compiler can produce two kinds of diagnostics: errors and
+warnings.  Each kind has a different purpose:
+
+@itemize @w{}
+@item
+@emph{Errors} report problems that make it impossible to compile your
+program.  GNU CC reports errors with the source file name and line
+number where the problem is apparent.
+
+@item
+@emph{Warnings} report other unusual conditions in your code that
+@emph{may} indicate a problem, although compilation can (and does)
+proceed.  Warning messages also report the source file name and line
+number, but include the text @samp{warning:} to distinguish them
+from error messages.
+@end itemize
+
+Warnings may indicate danger points where you should check to make sure
+that your program really does what you intend; or the use of obsolete
+features; or the use of nonstandard features of GNU C or C++.  Many
+warnings are issued only if you ask for them, with one of the @samp{-W}
+options (for instance, @samp{-Wall} requests a variety of useful
+warnings).
+
+GNU CC always tries to compile your program if possible; it never
+gratuitously rejects a program whose meaning is clear merely because
+(for instance) it fails to conform to a standard.  In some cases,
+however, the C and C++ standards specify that certain extensions are
+forbidden, and a diagnostic @emph{must} be issued by a conforming
+compiler.  The @samp{-pedantic} option tells GNU CC to issue warnings in
+such cases; @samp{-pedantic-errors} says to make them errors instead.
+This does not mean that @emph{all} non-ANSI constructs get warnings
+or errors.
+
+@xref{Warning Options,,Options to Request or Suppress Warnings}, for
+more detail on these and related command-line options.

+@cindex reporting bugs
+
+Your bug reports play an essential role in making GNU CC reliable.
+
+When you encounter a problem, the first thing to do is to see if it is
+already known.  @xref{Trouble}.  If it isn't known, then you should
+report the problem.
+
+Reporting a bug may help you by bringing a solution to your problem, or
+it may not.  (If it does not, look in the service directory; see
+@ref{Service}.)  In any case, the principal function of a bug report is
+to help the entire community by making the next version of GNU CC work
+better.  Bug reports are your contribution to the maintenance of GNU CC.
+
+Since the maintainers are very overloaded, we cannot respond to every
+bug report.  However, if the bug has not been fixed, we are likely to
+send you a patch and ask you to tell us whether it works.
+
+In order for a bug report to serve its purpose, you must include the
+information that makes for fixing the bug.

+@node Bug Criteria
+@section Have You Found a Bug?
+@cindex bug criteria
+
+If you are not sure whether you have found a bug, here are some guidelines:
+
+@itemize @bullet
+@cindex fatal signal
+@cindex core dump
+@item
+If the compiler gets a fatal signal, for any input whatever, that is a
+compiler bug.  Reliable compilers never crash.
+
+@cindex invalid assembly code
+@cindex assembly code, invalid
+@item
+If the compiler produces invalid assembly code, for any input whatever
+(except an @code{asm} statement), that is a compiler bug, unless the
+compiler reports errors (not just warnings) which would ordinarily
+prevent the assembler from being run.
+
+@cindex undefined behavior
+@cindex undefined function value
+@cindex increment operators
+@item
+If the compiler produces valid assembly code that does not correctly
+execute the input source code, that is a compiler bug.
+
+However, you must double-check to make sure, because you may have run
+into an incompatibility between GNU C and traditional C
+(@pxref{Incompatibilities}).  These incompatibilities might be considered
+bugs, but they are inescapable consequences of valuable features.
+
+Or you may have a program whose behavior is undefined, which happened
+by chance to give the desired results with another C or C++ compiler.
+
+For example, in many nonoptimizing compilers, you can write @samp{x;}
+at the end of a function instead of @samp{return x;}, with the same
+results.  But the value of the function is undefined if @code{return}
+is omitted; it is not a bug when GNU CC produces different results.
+
+Problems often result from expressions with two increment operators,
+as in @code{f (*p++, *p++)}.  Your previous compiler might have
+interpreted that expression the way you intended; GNU CC might
+interpret it another way.  Neither compiler is wrong.  The bug is
+in your code.
+
+After you have localized the error to a single source line, it should
+be easy to check for these things.  If your program is correct and
+well defined, you have found a compiler bug.
+
+@item
+If the compiler produces an error message for valid input, that is a
+compiler bug.
+
+@cindex invalid input
+@item
+If the compiler does not produce an error message for invalid input,
+that is a compiler bug.  However, you should note that your idea of
+``invalid input'' might be my idea of ``an extension'' or ``support
+for traditional practice''.
+
+@item
+If you are an experienced user of C or C++ compilers, your suggestions
+for improvement of GNU CC or GNU C++ are welcome in any case.

+@strong{Do not send bug reports to @samp{help-gcc@@prep.ai.mit.edu} or

+@node Bug Reporting
+@section How to Report Bugs
+@cindex compiler bugs, reporting
+
+The fundamental principle of reporting bugs usefully is this:
+@strong{report all the facts}.  If you are not sure whether to state a
+fact or leave it out, state it!
+
+Often people omit facts because they think they know what causes the
+problem and they conclude that some details don't matter.  Thus, you might
+assume that the name of the variable you use in an example does not matter.
+Well, probably it doesn't, but one cannot be sure.  Perhaps the bug is a
+stray memory reference which happens to fetch from the location where that
+name is stored in memory; perhaps, if the name were different, the contents
+of that location would fool the compiler into doing the right thing despite
+the bug.  Play it safe and give a specific, complete example.  That is the
+easiest thing for you to do, and the most helpful.
+
+Keep in mind that the purpose of a bug report is to enable someone to
+fix the bug if it is not known.  It isn't very important what happens if
+the bug is already known.  Therefore, always write your bug reports on
+the assumption that the bug is not known.
+
+Sometimes people give a few sketchy facts and ask, ``Does this ring a
+bell?''  This cannot help us fix a bug, so it is basically useless.  We
+respond by asking for enough details to enable us to investigate.
+You might as well expedite matters by sending them to begin with.
+
+Try to make your bug report self-contained.  If we have to ask you for
+more information, it is best if you include all the previous information
+in your response, as well as the information that was missing.
+
+Please report each bug in a separate message.  This makes it easier for
+us to track which bugs have been fixed and to forward your bugs reports
+to the appropriate maintainer.
+
+Do not compress and encode any part of your bug report using programs
+such as @file{uuencode}.  If you do so it will slow down the processing
+of your bug.  If you must submit multiple large files, use @file{shar},
+which allows us to read your message without having to run any
+decompression programs.
+
+To enable someone to investigate the bug, you should include all these
+things:
+
+@itemize @bullet
+@item
+The version of GNU CC.  You can get this by running it with the
+@samp{-v} option.
+
+Without this, we won't know whether there is any point in looking for
+the bug in the current version of GNU CC.
+
+@item
+A complete input file that will reproduce the bug.  If the bug is in the
+C preprocessor, send a source file and any header files that it
+requires.  If the bug is in the compiler proper (@file{cc1}), run your
+source file through the C preprocessor by doing @samp{gcc -E
+@var{sourcefile} > @var{outfile}}, then include the contents of
+@var{outfile} in the bug report.  (When you do this, use the same
+@samp{-I}, @samp{-D} or @samp{-U} options that you used in actual
+compilation.)
+
+A single statement is not enough of an example.  In order to compile it,
+it must be embedded in a complete file of compiler input; and the bug
+might depend on the details of how this is done.
+
+Without a real example one can compile, all anyone can do about your bug
+report is wish you luck.  It would be futile to try to guess how to
+provoke the bug.  For example, bugs in register allocation and reloading
+frequently depend on every little detail of the function they happen in.
+
+Even if the input file that fails comes from a GNU program, you should
+still send the complete test case.  Don't ask the GNU CC maintainers to
+do the extra work of obtaining the program in question---they are all
+overworked as it is.  Also, the problem may depend on what is in the
+header files on your system; it is unreliable for the GNU CC maintainers
+to try the problem with the header files available to them.  By sending
+CPP output, you can eliminate this source of uncertainty and save us
+a certain percentage of wild goose chases.
+
+@item
+The command arguments you gave GNU CC or GNU C++ to compile that example
+and observe the bug.  For example, did you use @samp{-O}?  To guarantee
+you won't omit something important, list all the options.
+
+If we were to try to guess the arguments, we would probably guess wrong
+and then we would not encounter the bug.
+
+@item
+The type of machine you are using, and the operating system name and
+version number.
+
+@item
+The operands you gave to the @code{configure} command when you installed
+the compiler.
+
+@item
+A complete list of any modifications you have made to the compiler
+source.  (We don't promise to investigate the bug unless it happens in
+an unmodified compiler.  But if you've made modifications and don't tell
+us, then you are sending us on a wild goose chase.)
+
+Be precise about these changes.  A description in English is not
+enough---send a context diff for them.
+
+Adding files of your own (such as a machine description for a machine we
+don't support) is a modification of the compiler source.
+
+@item
+Details of any other deviations from the standard procedure for installing
+GNU CC.
+
+@item
+A description of what behavior you observe that you believe is
+incorrect.  For example, ``The compiler gets a fatal signal,'' or,
+``The assembler instruction at line 208 in the output is incorrect.''
+
+Of course, if the bug is that the compiler gets a fatal signal, then one
+can't miss it.  But if the bug is incorrect output, the maintainer might
+not notice unless it is glaringly wrong.  None of us has time to study
+all the assembler code from a 50-line C program just on the chance that
+one instruction might be wrong.  We need @emph{you} to do this part!
+
+Even if the problem you experience is a fatal signal, you should still
+say so explicitly.  Suppose something strange is going on, such as, your
+copy of the compiler is out of synch, or you have encountered a bug in
+the C library on your system.  (This has happened!)  Your copy might
+crash and the copy here would not.  If you @i{said} to expect a crash,
+then when the compiler here fails to crash, we would know that the bug
+was not happening.  If you don't say to expect a crash, then we would
+not know whether the bug was happening.  We would not be able to draw
+any conclusion from our observations.
+
+If the problem is a diagnostic when compiling GNU CC with some other
+compiler, say whether it is a warning or an error.
+
+Often the observed symptom is incorrect output when your program is run.
+Sad to say, this is not enough information unless the program is short
+and simple.  None of us has time to study a large program to figure out
+how it would work if compiled correctly, much less which line of it was
+compiled wrong.  So you will have to do that.  Tell us which source line
+it is, and what incorrect result happens when that line is executed.  A
+person who understands the program can find this as easily as finding a
+bug in the program itself.
+
+@item
+If you send examples of assembler code output from GNU CC or GNU C++,
+please use @samp{-g} when you make them.  The debugging information
+includes source line numbers which are essential for correlating the
+output with the input.
+
+@item
+If you wish to mention something in the GNU CC source, refer to it by
+context, not by line number.
+
+The line numbers in the development sources don't match those in your
+sources.  Your line numbers would convey no useful information to the
+maintainers.
+
+@item
+Additional information from a debugger might enable someone to find a
+problem on a machine which he does not have available.  However, you
+need to think when you collect this information if you want it to have
+any chance of being useful.
+
+@cindex backtrace for bug reports
+For example, many people send just a backtrace, but that is never
+useful by itself.  A simple backtrace with arguments conveys little
+about GNU CC because the compiler is largely data-driven; the same
+functions are called over and over for different RTL insns, doing
+different things depending on the details of the insn.
+
+Most of the arguments listed in the backtrace are useless because they
+are pointers to RTL list structure.  The numeric values of the
+pointers, which the debugger prints in the backtrace, have no
+significance whatever; all that matters is the contents of the objects
+they point to (and most of the contents are other such pointers).
+
+In addition, most compiler passes consist of one or more loops that
+scan the RTL insn sequence.  The most vital piece of information about
+such a loop---which insn it has reached---is usually in a local variable,
+not in an argument.
+
+@findex debug_rtx
+What you need to provide in addition to a backtrace are the values of
+the local variables for several stack frames up.  When a local
+variable or an argument is an RTX, first print its value and then use
+the GDB command @code{pr} to print the RTL expression that it points
+to.  (If GDB doesn't run on your machine, use your debugger to call
+the function @code{debug_rtx} with the RTX as an argument.)  In
+general, whenever a variable is a pointer, its value is no use
+without the data it points to.
+@end itemize
+
+Here are some things that are not necessary:
+
+@itemize @bullet
+@item
+A description of the envelope of the bug.
+
+Often people who encounter a bug spend a lot of time investigating
+which changes to the input file will make the bug go away and which
+changes will not affect it.
+
+This is often time consuming and not very useful, because the way we
+will find the bug is by running a single example under the debugger with
+breakpoints, not by pure deduction from a series of examples.  You might
+as well save your time for something else.
+
+Of course, if you can find a simpler example to report @emph{instead} of
+the original one, that is a convenience.  Errors in the output will be
+easier to spot, running under the debugger will take less time, etc.
+Most GNU CC bugs involve just one function, so the most straightforward
+way to simplify an example is to delete all the function definitions
+except the one where the bug occurs.  Those earlier in the file may be
+replaced by external declarations if the crucial function depends on
+them.  (Exception: inline functions may affect compilation of functions
+defined later in the file.)
+
+However, simplification is not vital; if you don't want to do this,
+report the bug anyway and send the entire test case you used.
+
+@item
+In particular, some people insert conditionals @samp{#ifdef BUG} around
+a statement which, if removed, makes the bug not happen.  These are just
+clutter; we won't pay any attention to them anyway.  Besides, you should
+send us cpp output, and that can't have conditionals.
+
+@item
+A patch for the bug.
+
+A patch for the bug is useful if it is a good one.  But don't omit the
+necessary information, such as the test case, on the assumption that a
+patch is all we need.  We might see problems with your patch and decide
+to fix the problem another way, or we might not understand it at all.
+
+Sometimes with a program as complicated as GNU CC it is very hard to
+construct an example that will make the program follow a certain path
+through the code.  If you don't send the example, we won't be able to
+construct one, so we won't be able to verify that the bug is fixed.
+
+And if we can't understand what bug you are trying to fix, or why your
+patch should be an improvement, we won't install it.  A test case will
+help us to understand.
+
+@xref{Sending Patches}, for guidelines on how to make it easy for us to
+understand and install your patches.
+
+@item
+A guess about what the bug is or what it depends on.
+
+Such guesses are usually wrong.  Even I can't guess right about such
+things without first using the debugger to find the facts.
+
+@item
+A core dump file.
+
+We have no way of examining a core dump for your type of machine
+unless we have an identical system---and if we do have one,
+we should be able to reproduce the crash ourselves.

+
+@itemize @bullet
+@item
+Send an explanation with your changes of what problem they fix or what
+improvement they bring about.  For a bug fix, just include a copy of the
+bug report, and explain why the change fixes the bug.
+
+(Referring to a bug report is not as good as including it, because then
+we will have to look it up, and we have probably already deleted it if
+we've already fixed the bug.)
+
+@item
+Always include a proper bug report for the problem you think you have
+fixed.  We need to convince ourselves that the change is right before
+installing it.  Even if it is right, we might have trouble judging it if
+we don't have a way to reproduce the problem.
+
+@item
+Include all the comments that are appropriate to help people reading the
+source in the future understand why this change was needed.
+
+@item
+Don't mix together changes made for different reasons.
+Send them @emph{individually}.
+
+If you make two changes for separate reasons, then we might not want to
+install them both.  We might want to install just one.  If you send them
+all jumbled together in a single set of diffs, we have to do extra work
+to disentangle them---to figure out which parts of the change serve
+which purpose.  If we don't have time for this, we might have to ignore
+your changes entirely.
+
+If you send each change as soon as you have written it, with its own
+explanation, then the two changes never get tangled up, and we can
+consider each one properly without any extra work to disentangle them.
+
+Ideally, each change you send should be impossible to subdivide into
+parts that we might want to consider separately, because each of its
+parts gets its motivation from the other parts.
+
+@item
+Send each change as soon as that change is finished.  Sometimes people
+think they are helping us by accumulating many changes to send them all
+together.  As explained above, this is absolutely the worst thing you
+could do.
+
+Since you should send each change separately, you might as well send it
+right away.  That gives us the option of installing it immediately if it
+is important.
+
+@item
+Use @samp{diff -c} to make your diffs.  Diffs without context are hard
+for us to install reliably.  More than that, they make it hard for us to
+study the diffs to decide whether we want to install them.  Unidiff
+format is better than contextless diffs, but not as easy to read as
+@samp{-c} format.
+
+If you have GNU diff, use @samp{diff -cp}, which shows the name of the
+function that each change occurs in.
+
+@item
+Write the change log entries for your changes.  We get lots of changes,
+and we don't have time to do all the change log writing ourselves.
+
+Read the @file{ChangeLog} file to see what sorts of information to put
+in, and to learn the style that we use.  The purpose of the change log
+is to show people where to find what was changed.  So you need to be
+specific about what functions you changed; in large functions, it's
+often helpful to indicate where within the function the change was.
+
+On the other hand, once you have shown people where to find the change,
+you need not explain its purpose.  Thus, if you add a new function, all
+you need to say about it is that it is new.  If you feel that the
+purpose needs explaining, it probably does---but the explanation will be
+much more useful if you put it in comments in the code.
+
+If you would like your name to appear in the header line for who made
+the change, send us the header line.
+
+@item
+When you write the fix, keep in mind that we can't install a change that
+would break other systems.
+
+People often suggest fixing a problem by changing machine-independent
+files such as @file{toplev.c} to do something special that a particular
+system needs.  Sometimes it is totally obvious that such changes would
+break GNU CC for almost all users.  We can't possibly make a change like
+that.  At best it might tell us how to write another patch that would
+solve the problem acceptably.
+
+Sometimes people send fixes that @emph{might} be an improvement in
+general---but it is hard to be sure of this.  It's hard to install
+such changes because we have to study them very carefully.  Of course,
+a good explanation of the reasoning by which you concluded the change
+was correct can help convince us.
+
+The safest changes are changes to the configuration files for a
+particular machine.  These are safe because they can't create new bugs
+on other machines.
+
+Please help us keep up with the workload by designing the patch in a
+form that is good to install.

+@cindex include files and VMS
+@cindex VMS and include files
+@cindex header files and VMS
+Due to the differences between the filesystems of Unix and VMS, GNU CC
+attempts to translate file names in @samp{#include} into names that VMS
+will understand.  The basic strategy is to prepend a prefix to the
+specification of the include file, convert the whole filename to a VMS
+filename, and then try to open the file.  GNU CC tries various prefixes
+one by one until one of them succeeds:
+
+@enumerate
+@item
+The first prefix is the @samp{GNU_CC_INCLUDE:} logical name: this is
+where GNU C header files are traditionally stored.  If you wish to store
+header files in non-standard locations, then you can assign the logical
+@samp{GNU_CC_INCLUDE} to be a search list, where each element of the
+list is suitable for use with a rooted logical.
+
+@item
+The next prefix tried is @samp{SYS$SYSROOT:[SYSLIB.]}.  This is where
+VAX-C header files are traditionally stored.
+
+@item
+If the include file specification by itself is a valid VMS filename, the
+preprocessor then uses this name with no prefix in an attempt to open
+the include file.
+
+@item
+If the file specification is not a valid VMS filename (i.e. does not
+contain a device or a directory specifier, and contains a @samp{/}
+character), the preprocessor tries to convert it from Unix syntax to
+VMS syntax.
+
+Conversion works like this: the first directory name becomes a device,
+and the rest of the directories are converted into VMS-format directory
+names.  For example, the name @file{X11/foobar.h} is
+translated to @file{X11:[000000]foobar.h} or @file{X11:foobar.h},
+whichever one can be opened.  This strategy allows you to assign a
+logical name to point to the actual location of the header files.
+
+@item
+If none of these strategies succeeds, the @samp{#include} fails.
+@end enumerate
+
+Include directives of the form:
+
+@example
+#include foobar
+@end example
+
+@noindent
+are a common source of incompatibility between VAX-C and GNU CC.  VAX-C
+treats this much like a standard @code{#include <foobar.h>} directive.
+That is incompatible with the ANSI C behavior implemented by GNU CC: to
+expand the name @code{foobar} as a macro.  Macro expansion should
+eventually yield one of the two standard formats for @code{#include}:
+
+@example
+#include "@var{file}"
+#include <@var{file}>
+@end example
+
+If you have this problem, the best solution is to modify the source to
+convert the @code{#include} directives to one of the two standard forms.
+That will work with either compiler.  If you want a quick and dirty fix,
+define the file names as macros with the proper expansion, like this:
+
+@example
+#define stdio <stdio.h>
+@end example
+
+@noindent
+This will work, as long as the name doesn't conflict with anything else
+in the program.
+
+Another source of incompatibility is that VAX-C assumes that:
+
+@example
+#include "foobar"
+@end example
+
+@noindent
+is actually asking for the file @file{foobar.h}.  GNU CC does not
+make this assumption, and instead takes what you ask for literally;
+it tries to read the file @file{foobar}.  The best way to avoid this
+problem is to always specify the desired file extension in your include
+directives.
+
+GNU CC for VMS is distributed with a set of include files that is
+sufficient to compile most general purpose programs.  Even though the
+GNU CC distribution does not contain header files to define constants
+and structures for some VMS system-specific functions, there is no
+reason why you cannot use GNU CC with any of these functions.  You first
+may have to generate or create header files, either by using the public
+domain utility @code{UNSDL} (which can be found on a DECUS tape), or by
+extracting the relevant modules from one of the system macro libraries,
+and using an editor to construct a C header file.
+
+A @code{#include} file name cannot contain a DECNET node name.  The
+preprocessor reports an I/O error if you attempt to use a node name,
+whether explicitly, or implicitly via a logical name.

+
+@findex GLOBALREF
+@findex GLOBALDEF
+@findex GLOBALVALUEDEF
+@findex GLOBALVALUEREF
+GNU CC does not provide the @code{globalref}, @code{globaldef} and
+@code{globalvalue} keywords of VAX-C.  You can get the same effect with
+an obscure feature of GAS, the GNU assembler.  (This requires GAS
+version 1.39 or later.)  The following macros allow you to use this
+feature in a fairly natural way:
+
+@smallexample
+#ifdef __GNUC__
+#define GLOBALREF(TYPE,NAME)                      \
+  TYPE NAME                                       \
+  asm ("_$$PsectAttributes_GLOBALSYMBOL$$" #NAME)
+#define GLOBALDEF(TYPE,NAME,VALUE)                \
+  TYPE NAME                                       \
+  asm ("_$$PsectAttributes_GLOBALSYMBOL$$" #NAME) \
+    = VALUE
+#define GLOBALVALUEREF(TYPE,NAME)                 \
+  const TYPE NAME[1]                              \
+  asm ("_$$PsectAttributes_GLOBALVALUE$$" #NAME)
+#define GLOBALVALUEDEF(TYPE,NAME,VALUE)           \
+  const TYPE NAME[1]                              \
+  asm ("_$$PsectAttributes_GLOBALVALUE$$" #NAME)  \
+    = @{VALUE@}
+#else
+#define GLOBALREF(TYPE,NAME) \
+  globalref TYPE NAME
+#define GLOBALDEF(TYPE,NAME,VALUE) \
+  globaldef TYPE NAME = VALUE
+#define GLOBALVALUEDEF(TYPE,NAME,VALUE) \
+  globalvalue TYPE NAME = VALUE
+#define GLOBALVALUEREF(TYPE,NAME) \
+  globalvalue TYPE NAME
+#endif
+@end smallexample
+
+@noindent
+(The @code{_$$PsectAttributes_GLOBALSYMBOL} prefix at the start of the
+name is removed by the assembler, after it has modified the attributes
+of the symbol).  These macros are provided in the VMS binaries
+distribution in a header file @file{GNU_HACKS.H}.  An example of the
+usage is:
+
+@example
+GLOBALREF (int, ijk);
+GLOBALDEF (int, jkl, 0);
+@end example
+
+The macros @code{GLOBALREF} and @code{GLOBALDEF} cannot be used
+straightforwardly for arrays, since there is no way to insert the array
+dimension into the declaration at the right place.  However, you can
+declare an array with these macros if you first define a typedef for the
+array type, like this:
+
+@example
+typedef int intvector[10];
+GLOBALREF (intvector, foo);
+@end example
+
+Array and structure initializers will also break the macros; you can
+define the initializer to be a macro of its own, or you can expand the
+@code{GLOBALDEF} macro by hand.  You may find a case where you wish to
+use the @code{GLOBALDEF} macro with a large array, but you are not
+interested in explicitly initializing each element of the array.  In
+such cases you can use an initializer like: @code{@{0,@}}, which will
+initialize the entire array to @code{0}.
+
+A shortcoming of this implementation is that a variable declared with
+@code{GLOBALVALUEREF} or @code{GLOBALVALUEDEF} is always an array.  For
+example, the declaration:
+
+@example
+GLOBALVALUEREF(int, ijk);
+@end example
+
+@noindent
+declares the variable @code{ijk} as an array of type @code{int [1]}.
+This is done because a globalvalue is actually a constant; its ``value''
+is what the linker would normally consider an address.  That is not how
+an integer value works in C, but it is how an array works.  So treating
+the symbol as an array name gives consistent results---with the
+exception that the value seems to have the wrong type.  @strong{Don't
+try to access an element of the array.}  It doesn't have any elements.
+The array ``address'' may not be the address of actual storage.
+
+The fact that the symbol is an array may lead to warnings where the
+variable is used.  Insert type casts to avoid the warnings.  Here is an
+example; it takes advantage of the ANSI C feature allowing macros that
+expand to use the same name as the macro itself.
+
+@example
+GLOBALVALUEREF (int, ss$_normal);
+GLOBALVALUEDEF (int, xyzzy,123);
+#ifdef __GNUC__
+#define ss$_normal ((int) ss$_normal)
+#define xyzzy ((int) xyzzy)
+#endif
+@end example
+
+Don't use @code{globaldef} or @code{globalref} with a variable whose
+type is an enumeration type; this is not implemented.  Instead, make the
+variable an integer, and use a @code{globalvaluedef} for each of the
+enumeration values.  An example of this would be:
+
+@example
+#ifdef __GNUC__
+GLOBALDEF (int, color, 0);
+GLOBALVALUEDEF (int, RED, 0);
+GLOBALVALUEDEF (int, BLUE, 1);
+GLOBALVALUEDEF (int, GREEN, 3);
+#else
+enum globaldef color @{RED, BLUE, GREEN = 3@};
+#endif
+@end example

+@section Other VMS Issues
+
+@cindex exit status and VMS
+@cindex return value of @code{main}
+@cindex @code{main} and the exit status
+GNU CC automatically arranges for @code{main} to return 1 by default if
+you fail to specify an explicit return value.  This will be interpreted
+by VMS as a status code indicating a normal successful completion.
+Version 1 of GNU CC did not provide this default.
+
+GNU CC on VMS works only with the GNU assembler, GAS.  You need version
+1.37 or later of GAS in order to produce value debugging information for
+the VMS debugger.  Use the ordinary VMS linker with the object files
+produced by GAS.
+
+@cindex shared VMS run time system
+@cindex @file{VAXCRTL}
+Under previous versions of GNU CC, the generated code would occasionally
+give strange results when linked to the sharable @file{VAXCRTL} library.
+Now this should work.
+
+A caveat for use of @code{const} global variables: the @code{const}
+modifier must be specified in every external declaration of the variable
+in all of the source files that use that variable.  Otherwise the linker
+will issue warnings about conflicting attributes for the variable.  Your
+program will still work despite the warnings, but the variable will be
+placed in writable storage.
+
+@cindex name augmentation
+@cindex case sensitivity and VMS
+@cindex VMS and case sensitivity
+Although the VMS linker does distinguish between upper and lower case
+letters in global symbols, most VMS compilers convert all such symbols
+into upper case and most run-time library routines also have upper case
+names.  To be able to reliably call such routines, GNU CC (by means of
+the assembler GAS) converts global symbols into upper case like other
+VMS compilers.  However, since the usual practice in C is to distinguish
+case, GNU CC (via GAS) tries to preserve usual C behavior by augmenting
+each name that is not all lower case.  This means truncating the name
+to at most 23 characters and then adding more characters at the end
+which encode the case pattern of those 23.   Names which contain at
+least one dollar sign are an exception; they are converted directly into
+upper case without augmentation.
+
+Name augmentation yields bad results for programs that use precompiled
+libraries (such as Xlib) which were generated by another compiler.  You
+can use the compiler option @samp{/NOCASE_HACK} to inhibit augmentation;
+it makes external C functions and variables case-independent as is usual
+on VMS.  Alternatively, you could write all references to the functions
+and variables in such libraries using lower case; this will work on VMS,
+but is not portable to other systems.  The compiler option @samp{/NAMES}
+also provides control over global name handling.
+
+Function and variable names are handled somewhat differently with GNU
+C++.  The GNU C++ compiler performs @dfn{name mangling} on function
+names, which means that it adds information to the function name to
+describe the data types of the arguments that the function takes.  One
+result of this is that the name of a function can become very long.
+Since the VMS linker only recognizes the first 31 characters in a name,
+special action is taken to ensure that each function and variable has a
+unique name that can be represented in 31 characters.
+
+If the name (plus a name augmentation, if required) is less than 32
+characters in length, then no special action is performed.  If the name
+is longer than 31 characters, the assembler (GAS) will generate a
+hash string based upon the function name, truncate the function name to
+23 characters, and append the hash string to the truncated name.  If the
+@samp{/VERBOSE} compiler option is used, the assembler will print both
+the full and truncated names of each symbol that is truncated.
+
+The @samp{/NOCASE_HACK} compiler option should not be used when you are
+compiling programs that use libg++.  libg++ has several instances of
+objects (i.e.  @code{Filebuf} and @code{filebuf}) which become
+indistinguishable in a case-insensitive environment.  This leads to
+cases where you need to inhibit augmentation selectively (if you were
+using libg++ and Xlib in the same program, for example).  There is no
+special feature for doing this, but you can get the result by defining a
+macro for each mixed case symbol for which you wish to inhibit
+augmentation.  The macro should expand into the lower case equivalent of
+itself.  For example:
+
+@example
+#define StuDlyCapS studlycaps
+@end example
+
+These macro definitions can be placed in a header file to minimize the
+number of changes to your source code.

+@chapter GNU CC and Portability
+@cindex portability
+@cindex GNU CC and portability
+
+The main goal of GNU CC was to make a good, fast compiler for machines in
+the class that the GNU system aims to run on: 32-bit machines that address
+8-bit bytes and have several general registers.  Elegance, theoretical
+power and simplicity are only secondary.
+
+GNU CC gets most of the information about the target machine from a machine
+description which gives an algebraic formula for each of the machine's
+instructions.  This is a very clean way to describe the target.  But when
+the compiler needs information that is difficult to express in this
+fashion, I have not hesitated to define an ad-hoc parameter to the machine
+description.  The purpose of portability is to reduce the total work needed
+on the compiler; it was not of interest for its own sake.
+
+@cindex endianness
+@cindex autoincrement addressing, availability
+@findex abort
+GNU CC does not contain machine dependent code, but it does contain code
+that depends on machine parameters such as endianness (whether the most
+significant byte has the highest or lowest address of the bytes in a word)
+and the availability of autoincrement addressing.  In the RTL-generation
+pass, it is often necessary to have multiple strategies for generating code
+for a particular kind of syntax tree, strategies that are usable for different
+combinations of parameters.  Often I have not tried to address all possible
+cases, but only the common ones or only the ones that I have encountered.
+As a result, a new target may require additional strategies.  You will know
+if this happens because the compiler will call @code{abort}.  Fortunately,
+the new strategies can be added in a machine-independent fashion, and will
+affect only the target machines that need them.

+@chapter Interfacing to GNU CC Output
+@cindex interfacing to GNU CC output
+@cindex run-time conventions
+@cindex function call conventions
+@cindex conventions, run-time
+
+GNU CC is normally configured to use the same function calling convention
+normally in use on the target system.  This is done with the
+machine-description macros described (@pxref{Target Macros}).
+
+@cindex unions, returning
+@cindex structures, returning
+@cindex returning structures and unions
+However, returning of structure and union values is done differently on
+some target machines.  As a result, functions compiled with PCC
+returning such types cannot be called from code compiled with GNU CC,
+and vice versa.  This does not cause trouble often because few Unix
+library routines return structures or unions.
+
+GNU CC code returns structures and unions that are 1, 2, 4 or 8 bytes
+long in the same registers used for @code{int} or @code{double} return
+values.  (GNU CC typically allocates variables of such types in
+registers also.)  Structures and unions of other sizes are returned by
+storing them into an address passed by the caller (usually in a
+register).  The machine-description macros @code{STRUCT_VALUE} and
+@code{STRUCT_INCOMING_VALUE} tell GNU CC where to pass this address.
+
+By contrast, PCC on most target machines returns structures and unions
+of any size by copying the data into an area of static storage, and then
+returning the address of that storage as if it were a pointer value.
+The caller must copy the data from that memory area to the place where
+the value is wanted.  This is slower than the method used by GNU CC, and
+fails to be reentrant.
+
+On some target machines, such as RISC machines and the 80386, the
+standard system convention is to pass to the subroutine the address of
+where to return the value.  On these machines, GNU CC has been
+configured to be compatible with the standard compiler, when this method
+is used.  It may not be compatible for structures of 1, 2, 4 or 8 bytes.
+
+@cindex argument passing
+@cindex passing arguments
+GNU CC uses the system's standard convention for passing arguments.  On
+some machines, the first few arguments are passed in registers; in
+others, all are passed on the stack.  It would be possible to use
+registers for argument passing on any machine, and this would probably
+result in a significant speedup.  But the result would be complete
+incompatibility with code that follows the standard convention.  So this
+change is practical only if you are switching to GNU CC as the sole C
+compiler for the system.  We may implement register argument passing on
+certain machines once we have a complete GNU system so that we can
+compile the libraries with GNU CC.
+
+On some machines (particularly the Sparc), certain types of arguments
+are passed ``by invisible reference''.  This means that the value is
+stored in memory, and the address of the memory location is passed to
+the subroutine.
+
+@cindex @code{longjmp} and automatic variables
+If you use @code{longjmp}, beware of automatic variables.  ANSI C says that
+automatic variables that are not declared @code{volatile} have undefined
+values after a @code{longjmp}.  And this is all GNU CC promises to do,
+because it is very difficult to restore register variables correctly, and
+one of GNU CC's features is that it can put variables in registers without
+your asking it to.
+
+If you want a variable to be unaltered by @code{longjmp}, and you don't
+want to write @code{volatile} because old C compilers don't accept it,
+just take the address of the variable.  If a variable's address is ever
+taken, even if just to compute it and ignore it, then the variable cannot
+go in a register:
+
+@example
+@{
+  int careful;
+  &careful;
+  @dots{}
+@}
+@end example
+
+@cindex arithmetic libraries
+@cindex math libraries
+Code compiled with GNU CC may call certain library routines.  Most of
+them handle arithmetic for which there are no instructions.  This
+includes multiply and divide on some machines, and floating point
+operations on any machine for which floating point support is disabled
+with @samp{-msoft-float}.  Some standard parts of the C library, such as
+@code{bcopy} or @code{memcpy}, are also called automatically.  The usual
+function call interface is used for calling the library routines.
+
+These library routines should be defined in the library @file{libgcc.a},
+which GNU CC automatically searches whenever it links a program.  On
+machines that have multiply and divide instructions, if hardware
+floating point is in use, normally @file{libgcc.a} is not needed, but it
+is searched just in case.
+
+Each arithmetic function is defined in @file{libgcc1.c} to use the
+corresponding C arithmetic operator.  As long as the file is compiled
+with another C compiler, which supports all the C arithmetic operators,
+this file will work portably.  However, @file{libgcc1.c} does not work if
+compiled with GNU CC, because each arithmetic function would compile
+into a call to itself!

+@cindex top level of compiler
+The overall control structure of the compiler is in @file{toplev.c}.  This
+file is responsible for initialization, decoding arguments, opening and
+closing files, and sequencing the passes.
+
+@cindex parsing pass
+The parsing pass is invoked only once, to parse the entire input.  The RTL
+intermediate code for a function is generated as the function is parsed, a
+statement at a time.  Each statement is read in as a syntax tree and then
+converted to RTL; then the storage for the tree for the statement is
+reclaimed.  Storage for types (and the expressions for their sizes),
+declarations, and a representation of the binding contours and how they nest,
+remain until the function is finished being compiled; these are all needed
+to output the debugging information.
+
+@findex rest_of_compilation
+@findex rest_of_decl_compilation
+Each time the parsing pass reads a complete function definition or
+top-level declaration, it calls either the function
+@code{rest_of_compilation}, or the function
+@code{rest_of_decl_compilation} in @file{toplev.c}, which are
+responsible for all further processing necessary, ending with output of
+the assembler language.  All other compiler passes run, in sequence,
+within @code{rest_of_compilation}.  When that function returns from

+Parsing.  This pass reads the entire text of a function definition,
+constructing partial syntax trees.  This and RTL generation are no longer
+truly separate passes (formerly they were), but it is easier to think
+of them as separate.
+
+The tree representation does not entirely follow C syntax, because it is
+intended to support other languages as well.
+
+Language-specific data type analysis is also done in this pass, and every
+tree node that represents an expression has a data type attached.
+Variables are represented as declaration nodes.
+
+@cindex constant folding
+@cindex arithmetic simplifications
+@cindex simplifications, arithmetic
+Constant folding and some arithmetic simplifications are also done
+during this pass.
+
+The language-independent source files for parsing are

+There are also header files @file{tree.h} and @file{tree.def}
+which define the format of the tree representation.@refill
+
+@c Avoiding overfull is tricky here.
+The source files to parse C are
+@file{c-parse.in},
+@file{c-decl.c},
+@file{c-typeck.c},
+@file{c-aux-info.c},
+@file{c-convert.c},
+and @file{c-lang.c}
+along with header files
+@file{c-lex.h}, and
+@file{c-tree.h}.
+
+The source files for parsing C++ are @file{cp-parse.y},

+
+The special source files for parsing Objective C are
+@file{objc-parse.y}, @file{objc-actions.c}, @file{objc-tree.def}, and
+@file{objc-actions.h}.  Certain C-specific files are used for this as
+well.
+
+The file @file{c-common.c} is also used for all of the above languages.
+
+@cindex RTL generation
+@item
+RTL generation.  This is the conversion of syntax tree into RTL code.
+It is actually done statement-by-statement during parsing, but for
+most purposes it can be thought of as a separate pass.
+
+@cindex target-parameter-dependent code
+This is where the bulk of target-parameter-dependent code is found,
+since often it is necessary for strategies to apply only when certain
+standard kinds of instructions are available.  The purpose of named
+instruction patterns is to provide this information to the RTL
+generation pass.
+
+@cindex tail recursion optimization
+Optimization is done in this pass for @code{if}-conditions that are
+comparisons, boolean operations or conditional expressions.  Tail
+recursion is detected at this time also.  Decisions are made about how
+best to arrange loops and how to output @code{switch} statements.
+
+@c Avoiding overfull is tricky here.
+The source files for RTL generation include
+@file{stmt.c},
+@file{calls.c},
+@file{expr.c},
+@file{explow.c},
+@file{expmed.c},
+@file{function.c},
+@file{optabs.c}
+and @file{emit-rtl.c}.
+Also, the file
+@file{insn-emit.c}, generated from the machine description by the
+program @code{genemit}, is used in this pass.  The header file
+@file{expr.h} is used for communication within this pass.@refill
+
+@findex genflags
+@findex gencodes
+The header files @file{insn-flags.h} and @file{insn-codes.h},
+generated from the machine description by the programs @code{genflags}
+and @code{gencodes}, tell this pass which standard names are available
+for use and which patterns correspond to them.@refill
+
+Aside from debugging information output, none of the following passes
+refers to the tree structure representation of the function (only
+part of which is saved).
+
+@cindex inline, automatic
+The decision of whether the function can and should be expanded inline
+in its subsequent callers is made at the end of rtl generation.  The
+function must meet certain criteria, currently related to the size of
+the function and the types and number of parameters it has.  Note that
+this function may contain loops, recursive calls to itself
+(tail-recursive functions can be inlined!), gotos, in short, all
+constructs supported by GNU CC.  The file @file{integrate.c} contains
+the code to save a function's rtl for later inlining and to inline that
+rtl when the function is called.  The header file @file{integrate.h}
+is also used for this purpose.
+
+The option @samp{-dr} causes a debugging dump of the RTL code after
+this pass.  This dump file's name is made by appending @samp{.rtl} to
+the input file name.
+
+@cindex jump optimization
+@cindex unreachable code
+@cindex dead code
+@item
+Jump optimization.  This pass simplifies jumps to the following
+instruction, jumps across jumps, and jumps to jumps.  It deletes
+unreferenced labels and unreachable code, except that unreachable code
+that contains a loop is not recognized as unreachable in this pass.
+(Such loops are deleted later in the basic block analysis.)  It also
+converts some code originally written with jumps into sequences of
+instructions that directly set values from the results of comparisons,
+if the machine has such instructions.
+
+Jump optimization is performed two or three times.  The first time is
+immediately following RTL generation.  The second time is after CSE,
+but only if CSE says repeated jump optimization is needed.  The
+last time is right before the final pass.  That time, cross-jumping
+and deletion of no-op move instructions are done together with the
+optimizations described above.
+
+The source file of this pass is @file{jump.c}.
+
+The option @samp{-dj} causes a debugging dump of the RTL code after
+this pass is run for the first time.  This dump file's name is made by
+appending @samp{.jump} to the input file name.
+
+@cindex register use analysis
+@item
+Register scan.  This pass finds the first and last use of each
+register, as a guide for common subexpression elimination.  Its source
+is in @file{regclass.c}.
+
+@cindex jump threading
+@item
+Jump threading.  This pass detects a condition jump that branches to an
+identical or inverse test.  Such jumps can be @samp{threaded} through
+the second conditional test.  The source code for this pass is in
+@file{jump.c}.  This optimization is only performed if
+@samp{-fthread-jumps} is enabled.
+
+@cindex common subexpression elimination
+@cindex constant propagation
+@item
+Common subexpression elimination.  This pass also does constant
+propagation.  Its source file is @file{cse.c}.  If constant
+propagation causes conditional jumps to become unconditional or to
+become no-ops, jump optimization is run again when CSE is finished.
+
+The option @samp{-ds} causes a debugging dump of the RTL code after
+this pass.  This dump file's name is made by appending @samp{.cse} to
+the input file name.
+
+@cindex loop optimization
+@cindex code motion
+@cindex strength-reduction
+@item
+Loop optimization.  This pass moves constant expressions out of loops,
+and optionally does strength-reduction and loop unrolling as well.
+Its source files are @file{loop.c} and @file{unroll.c}, plus the header
+@file{loop.h} used for communication between them.  Loop unrolling uses
+some functions in @file{integrate.c} and the header @file{integrate.h}.
+
+The option @samp{-dL} causes a debugging dump of the RTL code after
+this pass.  This dump file's name is made by appending @samp{.loop} to
+the input file name.
+
+@item
+If @samp{-frerun-cse-after-loop} was enabled, a second common
+subexpression elimination pass is performed after the loop optimization
+pass.  Jump threading is also done again at this time if it was specified.
+
+The option @samp{-dt} causes a debugging dump of the RTL code after
+this pass.  This dump file's name is made by appending @samp{.cse2} to
+the input file name.
+
+@cindex register allocation, stupid
+@cindex stupid register allocation
+@item
+Stupid register allocation is performed at this point in a
+nonoptimizing compilation.  It does a little data flow analysis as
+well.  When stupid register allocation is in use, the next pass
+executed is the reloading pass; the others in between are skipped.
+The source file is @file{stupid.c}.
+
+@cindex data flow analysis
+@cindex analysis, data flow
+@cindex basic blocks
+@item
+Data flow analysis (@file{flow.c}).  This pass divides the program
+into basic blocks (and in the process deletes unreachable loops); then
+it computes which pseudo-registers are live at each point in the
+program, and makes the first instruction that uses a value point at
+the instruction that computed the value.
+
+@cindex autoincrement/decrement analysis
+This pass also deletes computations whose results are never used, and
+combines memory references with add or subtract instructions to make
+autoincrement or autodecrement addressing.
+
+The option @samp{-df} causes a debugging dump of the RTL code after
+this pass.  This dump file's name is made by appending @samp{.flow} to
+the input file name.  If stupid register allocation is in use, this
+dump file reflects the full results of such allocation.
+
+@cindex instruction combination
+@item
+Instruction combination (@file{combine.c}).  This pass attempts to
+combine groups of two or three instructions that are related by data
+flow into single instructions.  It combines the RTL expressions for
+the instructions by substitution, simplifies the result using algebra,
+and then attempts to match the result against the machine description.
+
+The option @samp{-dc} causes a debugging dump of the RTL code after
+this pass.  This dump file's name is made by appending @samp{.combine}
+to the input file name.
+
+@cindex instruction scheduling
+@cindex scheduling, instruction
+@item
+Instruction scheduling (@file{sched.c}).  This pass looks for
+instructions whose output will not be available by the time that it is
+used in subsequent instructions.  (Memory loads and floating point
+instructions often have this behavior on RISC machines).  It re-orders
+instructions within a basic block to try to separate the definition and
+use of items that otherwise would cause pipeline stalls.
+
+Instruction scheduling is performed twice.  The first time is immediately
+after instruction combination and the second is immediately after reload.
+
+The option @samp{-dS} causes a debugging dump of the RTL code after this
+pass is run for the first time.  The dump file's name is made by
+appending @samp{.sched} to the input file name.
+
+@cindex register class preference pass
+@item
+Register class preferencing.  The RTL code is scanned to find out
+which register class is best for each pseudo register.  The source
+file is @file{regclass.c}.
+
+@cindex register allocation
+@cindex local register allocation
+@item
+Local register allocation (@file{local-alloc.c}).  This pass allocates
+hard registers to pseudo registers that are used only within one basic
+block.  Because the basic block is linear, it can use fast and
+powerful techniques to do a very good job.
+
+The option @samp{-dl} causes a debugging dump of the RTL code after
+this pass.  This dump file's name is made by appending @samp{.lreg} to
+the input file name.
+
+@cindex global register allocation
+@item
+Global register allocation (@file{global.c}).  This pass
+allocates hard registers for the remaining pseudo registers (those
+whose life spans are not contained in one basic block).
+
+@cindex reloading
+@item
+Reloading.  This pass renumbers pseudo registers with the hardware
+registers numbers they were allocated.  Pseudo registers that did not
+get hard registers are replaced with stack slots.  Then it finds
+instructions that are invalid because a value has failed to end up in
+a register, or has ended up in a register of the wrong kind.  It fixes
+up these instructions by reloading the problematical values
+temporarily into registers.  Additional instructions are generated to
+do the copying.
+
+The reload pass also optionally eliminates the frame pointer and inserts
+instructions to save and restore call-clobbered registers around calls.
+
+Source files are @file{reload.c} and @file{reload1.c}, plus the header
+@file{reload.h} used for communication between them.
+
+The option @samp{-dg} causes a debugging dump of the RTL code after
+this pass.  This dump file's name is made by appending @samp{.greg} to
+the input file name.
+
+@cindex instruction scheduling
+@cindex scheduling, instruction
+@item
+Instruction scheduling is repeated here to try to avoid pipeline stalls
+due to memory loads generated for spilled pseudo registers.
+
+The option @samp{-dR} causes a debugging dump of the RTL code after
+this pass.  This dump file's name is made by appending @samp{.sched2}
+to the input file name.
+
+@cindex cross-jumping
+@cindex no-op move instructions
+@item
+Jump optimization is repeated, this time including cross-jumping
+and deletion of no-op move instructions.
+
+The option @samp{-dJ} causes a debugging dump of the RTL code after
+this pass.  This dump file's name is made by appending @samp{.jump2}
+to the input file name.
+
+@cindex delayed branch scheduling
+@cindex scheduling, delayed branch
+@item
+Delayed branch scheduling.  This optional pass attempts to find
+instructions that can go into the delay slots of other instructions,
+usually jumps and calls.  The source file name is @file{reorg.c}.
+
+The option @samp{-dd} causes a debugging dump of the RTL code after
+this pass.  This dump file's name is made by appending @samp{.dbr}
+to the input file name.
+
+@cindex register-to-stack conversion
+@item
+Conversion from usage of some hard registers to usage of a register
+stack may be done at this point.  Currently, this is supported only
+for the floating-point registers of the Intel 80387 coprocessor.   The
+source file name is @file{reg-stack.c}.
+
+The options @samp{-dk} causes a debugging dump of the RTL code after
+this pass.  This dump file's name is made by appending @samp{.stack}
+to the input file name.
+
+@cindex final pass
+@cindex peephole optimization
+@item
+Final.  This pass outputs the assembler code for the function.  It is
+also responsible for identifying spurious test and compare
+instructions.  Machine-specific peephole optimizations are performed
+at the same time.  The function entry and exit sequences are generated
+directly as assembler code in this pass; they never exist as RTL.
+
+The source files are @file{final.c} plus @file{insn-output.c}; the
+latter is generated automatically from the machine description by the
+tool @file{genoutput}.  The header file @file{conditions.h} is used
+for communication between these files.
+
+@cindex debugging information generation
+@item
+Debugging information output.  This is run after final because it must
+output the stack slot offsets for pseudo registers that did not get
+hard registers.  Source files are @file{dbxout.c} for DBX symbol table
+format, @file{sdbout.c} for SDB symbol table format, and
+@file{dwarfout.c} for DWARF symbol table format.
+@end itemize
+
+Some additional files are used by all or many passes:
+
+@itemize @bullet
+@item
+Every pass uses @file{machmode.def} and @file{machmode.h} which define
+the machine modes.
+
+@item
+Several passes use @file{real.h}, which defines the default
+representation of floating point constants and how to operate on them.
+
+@item
+All the passes that work with RTL use the header files @file{rtl.h}
+and @file{rtl.def}, and subroutines in file @file{rtl.c}.  The tools
+@code{gen*} also use these files to read and work with the machine
+description RTL.
+
+@findex genconfig
+@item
+Several passes refer to the header file @file{insn-config.h} which
+contains a few parameters (C macro definitions) generated
+automatically from the machine description RTL by the tool
+@code{genconfig}.
+
+@cindex instruction recognizer
+@item
+Several passes use the instruction recognizer, which consists of
+@file{recog.c} and @file{recog.h}, plus the files @file{insn-recog.c}
+and @file{insn-extract.c} that are generated automatically from the
+machine description by the tools @file{genrecog} and
+@file{genextract}.@refill
+
+@item
+Several passes use the header files @file{regs.h} which defines the
+information recorded about pseudo register usage, and @file{basic-block.h}
+which defines the information recorded about basic blocks.
+
+@item
+@file{hard-reg-set.h} defines the type @code{HARD_REG_SET}, a bit-vector
+with a bit for each hard register, and some macros to manipulate it.
+This type is just @code{int} if the machine has few enough hard registers;
+otherwise it is an array of @code{int} and some of the macros expand
+into loops.
+
+@item
+Several passes use instruction attributes.  A definition of the
+attributes defined for a particular machine is in file
+@file{insn-attr.h}, which is generated from the machine description by
+the program @file{genattr}.  The file @file{insn-attrtab.c} contains
+subroutines to obtain the attribute values for insns.  It is generated

+@chapter The Configuration File
+@cindex configuration file
+@cindex @file{xm-@var{machine}.h}
+
+The configuration file @file{xm-@var{machine}.h} contains macro
+definitions that describe the machine and system on which the compiler
+is running, unlike the definitions in @file{@var{machine}.h}, which
+describe the machine for which the compiler is producing output.  Most
+of the values in @file{xm-@var{machine}.h} are actually the same on all
+machines that GNU CC runs on, so large parts of all configuration files
+are identical.  But there are some macros that vary:
+
+@table @code
+@findex USG
+@item USG
+Define this macro if the host system is System V.
+
+@findex VMS
+@item VMS
+Define this macro if the host system is VMS.
+
+@findex FATAL_EXIT_CODE
+@item FATAL_EXIT_CODE
+A C expression for the status code to be returned when the compiler
+exits after serious errors.
+
+@findex SUCCESS_EXIT_CODE
+@item SUCCESS_EXIT_CODE
+A C expression for the status code to be returned when the compiler
+exits without serious errors.
+
+@findex HOST_WORDS_BIG_ENDIAN
+@item HOST_WORDS_BIG_ENDIAN
+Defined if the host machine stores words of multi-word values in
+big-endian order.  (GNU CC does not depend on the host byte ordering
+within a word.)
+
+@findex HOST_FLOAT_WORDS_BIG_ENDIAN
+@item HOST_FLOAT_WORDS_BIG_ENDIAN
+Define this macro to be 1 if the host machine stores @code{DFmode},
+@code{XFmode} or @code{TFmode} floating point numbers in memory with the
+word containing the sign bit at the lowest address; otherwise, define it
+to be zero.
+
+This macro need not be defined if the ordering is the same as for
+multi-word integers.
+
+@findex HOST_FLOAT_FORMAT
+@item HOST_FLOAT_FORMAT
+A numeric code distinguishing the floating point format for the host
+machine.  See @code{TARGET_FLOAT_FORMAT} in @ref{Storage Layout} for the
+alternatives and default.
+
+@findex HOST_BITS_PER_CHAR
+@item HOST_BITS_PER_CHAR
+A C expression for the number of bits in @code{char} on the host
+machine.
+
+@findex HOST_BITS_PER_SHORT
+@item HOST_BITS_PER_SHORT
+A C expression for the number of bits in @code{short} on the host
+machine.
+
+@findex HOST_BITS_PER_INT
+@item HOST_BITS_PER_INT
+A C expression for the number of bits in @code{int} on the host
+machine.
+
+@findex HOST_BITS_PER_LONG
+@item HOST_BITS_PER_LONG
+A C expression for the number of bits in @code{long} on the host
+machine.
+
+@findex ONLY_INT_FIELDS
+@item ONLY_INT_FIELDS
+Define this macro to indicate that the host compiler only supports
+@code{int} bit fields, rather than other integral types, including
+@code{enum}, as do most C compilers.
+
+@findex OBSTACK_CHUNK_SIZE
+@item OBSTACK_CHUNK_SIZE
+A C expression for the size of ordinary obstack chunks.
+If you don't define this, a usually-reasonable default is used.
+
+@findex OBSTACK_CHUNK_ALLOC
+@item OBSTACK_CHUNK_ALLOC
+The function used to allocate obstack chunks.
+If you don't define this, @code{xmalloc} is used.
+
+@findex OBSTACK_CHUNK_FREE
+@item OBSTACK_CHUNK_FREE
+The function used to free obstack chunks.
+If you don't define this, @code{free} is used.
+
+@findex USE_C_ALLOCA
+@item USE_C_ALLOCA
+Define this macro to indicate that the compiler is running with the
+@code{alloca} implemented in C.  This version of @code{alloca} can be
+found in the file @file{alloca.c}; to use it, you must also alter the
+@file{Makefile} variable @code{ALLOCA}.  (This is done automatically
+for the systems on which we know it is needed.)
+
+If you do define this macro, you should probably do it as follows:
+
+@example
+#ifndef __GNUC__
+#define USE_C_ALLOCA
+#else
+#define alloca __builtin_alloca
+#endif
+@end example
+
+@noindent
+so that when the compiler is compiled with GNU CC it uses the more
+efficient built-in @code{alloca} function.
+
+@item FUNCTION_CONVERSION_BUG
+@findex FUNCTION_CONVERSION_BUG
+Define this macro to indicate that the host compiler does not properly
+handle converting a function value to a pointer-to-function when it is
+used in an expression.
+
+@findex HAVE_VPRINTF
+@findex vprintf
+@item HAVE_VPRINTF
+Define this if the library function @code{vprintf} is available on your
+system.
+
+@findex MULTIBYTE_CHARS
+@item MULTIBYTE_CHARS
+Define this macro to enable support for multibyte characters in the
+input to GNU CC.  This requires that the host system support the ANSI C
+library functions for converting multibyte characters to wide
+characters.
+
+@findex HAVE_PUTENV
+@findex putenv
+@item HAVE_PUTENV
+Define this if the library function @code{putenv} is available on your
+system.
+
+@findex POSIX
+@item POSIX
+Define this if your system is POSIX.1 compliant.
+
+@findex HAVE_POPEN
+@findex popen
+@item HAVE_POPEN
+Define this if the library function @code{popen} is available on your
+system.
+
+@findex NO_SYS_SIGLIST
+@item NO_SYS_SIGLIST
+Define this if your system @emph{does not} provide the variable
+@code{sys_siglist}.
+
+@findex DONT_DECLARE_SYS_SIGLIST
+@item DONT_DECLARE_SYS_SIGLIST
+Define this if your system has the variable @code{sys_siglist}, and
+there is already a declaration of it in the system header files.
+
+@findex USE_PROTOTYPES
+@item USE_PROTOTYPES
+Define this to be 1 if you know that the host compiler supports
+prototypes, even if it doesn't define __STDC__, or define
+it to be 0 if you do not want any prototypes used in compiling
+GNU CC.  If @samp{USE_PROTOTYPES} is not defined, it will be
+determined automatically whether your compiler supports
+prototypes by checking if @samp{__STDC__} is defined.
+
+@findex NO_MD_PROTOTYPES
+@item NO_MD_PROTOTYPES
+Define this if you wish suppression of prototypes generated from
+the machine description file, but to use other prototypes within
+GNU CC.  If @samp{USE_PROTOTYPES} is defined to be 0, or the
+host compiler does not support prototypes, this macro has no
+effect.
+
+@findex MD_CALL_PROTOTYPES
+@item MD_CALL_PROTOTYPES
+Define this if you wish to generate prototypes for the
+@code{gen_call} or @code{gen_call_value} functions generated from
+the machine description file.  If @samp{USE_PROTOTYPES} is
+defined to be 0, or the host compiler does not support
+prototypes, or @samp{NO_MD_PROTOTYPES} is defined, this macro has
+no effect.  As soon as all of the machine descriptions are
+modified to have the appropriate number of arguments, this macro
+will be removed.
+
+@vindex sys_siglist
+Some systems do provide this variable, but with a different name such
+as @code{_sys_siglist}.  On these systems, you can define
+@code{sys_siglist} as a macro which expands into the name actually
+provided.
+
+@findex NO_STAB_H
+@item NO_STAB_H
+Define this if your system does not have the include file
+@file{stab.h}.  If @samp{USG} is defined, @samp{NO_STAB_H} is
+assumed.
+
+@findex PATH_SEPARATOR
+@item PATH_SEPARATOR
+Define this macro to be a C character constant representing the
+character used to separate components in paths.  The default value is.
+the colon character
+
+@findex DIR_SEPARATOR
+@item DIR_SEPARATOR
+If your system uses some character other than slash to separate
+directory names within a file specification, define this macro to be a C
+character constant specifying that character.  When GNU CC displays file
+names, the character you specify will be used.  GNU CC will test for
+both slash and the character you specify when parsing filenames.
+
+@findex OBJECT_SUFFIX
+@item OBJECT_SUFFIX
+Define this macro to be a C string representing the suffix for object
+files on your machine.  If you do not define this macro, GNU CC will use
+@samp{.o} as the suffix for object files.
+
+@findex EXECUTABLE_SUFFIX
+@item EXECUTABLE_SUFFIX
+Define this macro to be a C string representing the suffix for executable
+files on your machine.  If you do not define this macro, GNU CC will use
+the null string as the suffix for object files.
+
+@findex COLLECT_EXPORT_LIST
+@item COLLECT_EXPORT_LIST
+If defined, @code{collect2} will scan the individual object files
+specified on its command line and create an export list for the linker.
+Define this macro for systems like AIX, where the linker discards
+object files that are not referenced from @code{main} and uses export
+lists.
+@end table
+
+@findex bzero
+@findex bcmp
+In addition, configuration files for system V define @code{bcopy},
+@code{bzero} and @code{bcmp} as aliases.  Some files define @code{alloca}
+as a macro when compiled with GNU CC, in order to take advantage of the
+benefit of GNU CC's built-in @code{alloca}.

+@findex LIBGCC2_CFLAGS
+@item LIBGCC2_CFLAGS
+Compiler flags to use when compiling @file{libgcc2.c}.
+
+@findex LIB2FUNCS_EXTRA
+@item LIB2FUNCS_EXTRA
+A list of source file names to be compiled or assembled and inserted
+into @file{libgcc.a}.
+
+@findex CRTSTUFF_T_CFLAGS
+@item CRTSTUFF_T_CFLAGS
+Special flags used when compiling @file{crtstuff.c}.
+@xref{Initialization}.
+
+@findex CRTSTUFF_T_CFLAGS_S
+@item CRTSTUFF_T_CFLAGS_S
+Special flags used when compiling @file{crtstuff.c} for shared
+linking.  Used if you use @file{crtbeginS.o} and @file{crtendS.o}
+in @code{EXTRA-PARTS}.
+@xref{Initialization}.
+
+@findex MULTILIB_OPTIONS
+@item MULTILIB_OPTIONS
+For some targets, invoking GNU CC in different ways produces objects
+that can not be linked together.  For example, for some targets GNU CC
+produces both big and little endian code.  For these targets, you must
+arrange for multiple versions of @file{libgcc.a} to be compiled, one for
+each set of incompatible options.  When GNU CC invokes the linker, it
+arranges to link in the right version of @file{libgcc.a}, based on
+the command line options used.
+
+The @code{MULTILIB_OPTIONS} macro lists the set of options for which
+special versions of @file{libgcc.a} must be built.  Write options that
+are mutually incompatible side by side, separated by a slash.  Write
+options that may be used together separated by a space.  The build
+procedure will build all combinations of compatible options.
+
+For example, if you set @code{MULTILIB_OPTIONS} to @samp{m68000/m68020
+msoft-float}, @file{Makefile} will build special versions of
+@file{libgcc.a} using the sets of options @samp{-m68000}, @samp{-m68020},
+@samp{-msoft-float}, @samp{-m68000 -msoft-float}, and @samp{-m68020
+-msoft-float}.
+
+@findex MULTILIB_DIRNAMES
+@item MULTILIB_DIRNAMES
+If @code{MULTILIB_OPTIONS} is used, this variable specifies the
+directory names that should be used to hold the various libraries.
+Write one element in @code{MULTILIB_DIRNAMES} for each element in
+@code{MULTILIB_OPTIONS}.  If @code{MULTILIB_DIRNAMES} is not used, the
+default value will be @code{MULTILIB_OPTIONS}, with all slashes treated
+as spaces.
+
+For example, if @code{MULTILIB_OPTIONS} is specified as @samp{m68000/m68020
+msoft-float}, then the default value of @code{MULTILIB_DIRNAMES} is
+@samp{m68000 m68020 msoft-float}.  You may specify a different value if
+you desire a different set of directory names.
+
+@findex MULTILIB_MATCHES
+@item MULTILIB_MATCHES
+Sometimes the same option may be written in two different ways.  If an
+option is listed in @code{MULTILIB_OPTIONS}, GNU CC needs to know about
+any synonyms.  In that case, set @code{MULTILIB_MATCHES} to a list of
+items of the form @samp{option=option} to describe all relevant
+synonyms.  For example, @samp{m68000=mc68000 m68020=mc68020}.
+
+@findex MULTILIB_EXCEPTIONS
+@item MULTILIB_EXCEPTIONS
+Sometimes when there are multiple sets of @code{MULTILIB_OPTIONS} being
+specified, there are combinations that should not be built.  In that
+case, set @code{MULTILIB_EXCEPTIONS} to be all of the switch exceptions
+in shell case syntax that should not be built.
+
+For example, in the PowerPC embedded ABI support, it was not desirable

+@node Funding
+@unnumbered Funding Free Software
+
+If you want to have more free software a few years from now, it makes
+sense for you to help encourage people to contribute funds for its
+development.  The most effective approach known is to encourage
+commercial redistributors to donate.
+
+Users of free software systems can boost the pace of development by
+encouraging for-a-fee distributors to donate part of their selling price
+to free software developers---the Free Software Foundation, and others.
+
+The way to convince distributors to do this is to demand it and expect
+it from them.  So when you compare distributors, judge them partly by
+how much they give to free software development.  Show distributors
+they must compete to be the one who gives the most.
+
+To make this approach work, you must insist on numbers that you can
+compare, such as, ``We will donate ten dollars to the Frobnitz project
+for each disk sold.''  Don't be satisfied with a vague promise, such as
+``A portion of the profits are donated,'' since it doesn't give a basis
+for comparison.
+
+Even a precise fraction ``of the profits from this disk'' is not very
+meaningful, since creative accounting and unrelated business decisions
+can greatly alter what fraction of the sales price counts as profit.
+If the price you pay is $50, ten percent of the profit is probably
+less than a dollar; it might be a few cents, or nothing at all.
+
+Some redistributors do development work themselves.  This is useful too;
+but to keep everyone honest, you need to inquire how much they do, and
+what kind.  Some kinds of development make much more long-term
+difference than others.  For example, maintaining a separate version of
+a program contributes very little; maintaining the standard version of a
+program for the whole community contributes much.  Easy new ports
+contribute little, since someone else would surely do them; difficult
+ports such as adding a new CPU to the GNU C compiler contribute more;
+major new features or packages contribute the most.
+
+By establishing the idea that supporting further development is ``the
+proper thing to do'' when distributing free software for a fee, we can
+assure a steady flow of resources into making more free software.

+@quotation
+@i{This section is a political message from the League for Programming
+Freedom to the users of GNU CC.  We have included it here because the
+issue of interface copyright is important to the GNU project.}
+@end quotation
+
+Apple, Lotus, and now CDC have tried to create a new form of legal
+monopoly: a copyright on a user interface.
+
+An interface is a kind of language---a set of conventions for
+communication between two entities, human or machine.  Until a few years
+ago, the law seemed clear: interfaces were outside the domain of
+copyright, so programmers could program freely and implement whatever
+interface the users demanded.  Imitating de-facto standard interfaces,
+sometimes with improvements, was standard practice in the computer
+field.  These improvements, if accepted by the users, caught on and
+became the norm; in this way, much progress took place.
+
+Computer users, and most software developers, were happy with this state
+of affairs.  However, large companies such as Apple and Lotus would
+prefer a different system---one in which they can own interfaces and
+thereby rid themselves of all serious competitors.  They hope that
+interface copyright will give them, in effect, monopolies on major
+classes of software.
+
+Other large companies such as IBM and Digital also favor interface
+monopolies, for the same reason: if languages become property, they
+expect to own many de-facto standard languages.  But Apple and Lotus are
+the ones who have actually sued.  Apple's lawsuit was defeated, for
+reasons only partly related to the general issue of interface copyright.
+
+Lotus won lawsuits against two small companies, which were thus put out
+of business.  Then Lotus sued Borland; Lotus won in the trial court (no
+surprise, since it was the same court that had ruled for Lotus twice
+before), but the court of appeals ruled in favor of Borland, which was
+assisted by a friend-of-the-court brief from the League for Programming
+Freedom.
+
+Lotus appealed the case to the Supreme Court, which heard the case but
+was unable to reach a decision.  This failure means that the appeals
+court decision stands, in one portion of the United States, and may
+influence the other appeals courts, but it does not set a nationwide
+precedent.  The battle is not over, and it is not limited to the United
+States.
+
+The battle is extending into other areas of software as well.  In 1995 a
+company that produced a simulator for a CDC computer was shut down by a
+copyright lawsuit, in which CDC charged that the simulator infringed the
+copyright on the manuals for the computer.
+
+If the monopolists get their way, they will hobble the software field:
+
+@itemize @bullet
+@item
+Gratuitous incompatibilities will burden users.  Imagine if each car
+manufacturer had to design a different way to start, stop, and steer a
+car.
+
+@item
+Users will be ``locked in'' to whichever interface they learn; then they
+will be prisoners of one supplier, who will charge a monopolistic price.
+
+@item
+Large companies have an unfair advantage wherever lawsuits become
+commonplace.  Since they can afford to sue, they can intimidate smaller
+developers with threats even when they don't really have a case.
+
+@item
+Interface improvements will come slower, since incremental evolution
+through creative partial imitation will no longer occur.
+@end itemize
+
+If interface monopolies are accepted, other large companies are waiting
+to grab theirs:
+
+@itemize @bullet
+@item
+Adobe is expected to claim a monopoly on the interfaces of various
+popular application programs, if Lotus ultimately wins the case against
+Borland.
+
+@item
+Open Computing magazine reported a Microsoft vice president as threatening
+to sue people who imitate the interface of Windows.
+@end itemize
+
+Users invest a great deal of time and money in learning to use computer
+interfaces.  Far more, in fact, than software developers invest in
+developing @emph{and even implementing} the interfaces.  Whoever can own
+an interface, has made its users into captives, and misappropriated
+their investment.
+
+To protect our freedom from monopolies like these, a group of
+programmers and users have formed a grass-roots political organization,
+the League for Programming Freedom.
+
+The purpose of the League is to oppose monopolistic practices such as
+interface copyright and software patents.  The League calls for a return
+to the legal policies of the recent past, in which programmers could
+program freely.  The League is not concerned with free software as an
+issue, and is not affiliated with the Free Software Foundation.
+
+The League's activities include publicizing the issues, as is being done
+here, and filing friend-of-the-court briefs on behalf of defendants sued
+by monopolists.
+
+The League's membership rolls include Donald Knuth, the foremost
+authority on algorithms, John McCarthy, inventor of Lisp, Marvin Minsky,
+founder of the MIT Artificial Intelligence lab, Guy L. Steele, Jr.,
+author of well-known books on Lisp and C, as well as Richard Stallman,
+the developer of GNU CC.  Please join and add your name to the list.
+Membership dues in the League are $42 per year for programmers, managers
+and professionals; $10.50 for students; $21 for others.
+
+Activist members are especially important, but members who have no time
+to give are also important.  Surveys at major ACM conferences have
+indicated a vast majority of attendees agree with the League on both
+issues (interface copyrights and software patents).  If just ten percent
+of the programmers who agree with the League join the League, we will
+probably triumph.

+59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+@end display
+
+@unnumberedsec Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software---to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.

+@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+@end ifinfo
+
+@enumerate 0
+@item
+This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The ``Program'', below,
+refers to any such program or work, and a ``work based on the Program''
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term ``modification''.)  Each licensee is addressed as ``you''.
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+@item
+You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+@item
+You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+@enumerate a
+@item
+You must cause the modified files to carry prominent notices
+stating that you changed the files and the date of any change.
+
+@item
+You must cause any work that you distribute or publish, that in
+whole or in part contains or is derived from the Program or any
+part thereof, to be licensed as a whole at no charge to all third
+parties under the terms of this License.
+
+@item
+If the modified program normally reads commands interactively
+when run, you must cause it, when started running for such
+interactive use in the most ordinary way, to print or display an
+announcement including an appropriate copyright notice and a
+notice that there is no warranty (or else, saying that you provide
+a warranty) and that users may redistribute the program under
+these conditions, and telling the user how to view a copy of this
+License.  (Exception: if the Program itself is interactive but
+does not normally print such an announcement, your work based on
+the Program is not required to print an announcement.)
+@end enumerate
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+@item
+You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+@enumerate a
+@item
+Accompany it with the complete corresponding machine-readable
+source code, which must be distributed under the terms of Sections
+1 and 2 above on a medium customarily used for software interchange; or,
+
+@item
+Accompany it with a written offer, valid for at least three
+years, to give any third party, for a charge no more than your
+cost of physically performing source distribution, a complete
+machine-readable copy of the corresponding source code, to be
+distributed under the terms of Sections 1 and 2 above on a medium
+customarily used for software interchange; or,
+
+@item
+Accompany it with the information you received as to the offer
+to distribute corresponding source code.  (This alternative is
+allowed only for noncommercial distribution and only if you
+received the program in object code or executable form with such
+an offer, in accord with Subsection b above.)
+@end enumerate
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+@item
+You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+@item
+You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+@item
+Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+@item
+If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+@item
+If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+@item
+The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.

+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and ``any
+later version'', you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+

+If you wish to incorporate parts of the Program into other free

+to ask for permission.  For software which is copyrighted by the Free

+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the ``copyright'' line and a pointer to where the full notice is found.

+@item -fprofile-arcs
+Instrument @dfn{arcs} during compilation.  For each function of your
+program, GNU CC creates a program flow graph, then finds a spanning tree
+for the graph.  Only arcs that are not on the spanning tree have to be
+instrumented: the compiler adds code to count the number of times that these
+arcs are executed.  When an arc is the only exit or only entrance to a
+block, the instrumentation code can be added to the block; otherwise, a
+new basic block must be created to hold the instrumentation code.
+
+Since not every arc in the program must be instrumented, programs
+compiled with this option run faster than programs compiled with
+@samp{-a}, which adds instrumentation code to every basic block in the
+program.  The tradeoff: since @code{gcov} does not have
+execution counts for all branches, it must start with the execution
+counts for the instrumented branches, and then iterate over the program
+flow graph until the entire graph has been solved.  Hence, @code{gcov}

+@samp{-a}.
+
+@samp{-fprofile-arcs} also makes it possible to estimate branch
+probabilities, and to calculate basic block execution counts.  In

 Position-independent code requires special support, and therefore works
 only on certain machines.  For the 386, GNU CC supports PIC for System V
 but not for the Sun 386i.  Code generated for the IBM RS/6000 is always
 position-independent.

+@samp{-fprefix-function-name} option, which requests GNU CC to encapsulate
+your code and make other functions look as if they were compiled with
+@samp{-fcheck-memory-usage}.  This is done by calling ``stubs'',

+@node Stack Checking
+@subsection Specifying How Stack Checking is Done
+
+GNU CC will check that stack references are within the boundaries of
+the stack, if the @samp{-fstack-check} is specified, in one of three ways:
+
+@enumerate
+@item
+If the value of the @code{STACK_CHECK_BUILTIN} macro is nonzero, GNU CC
+will assume that you have arranged for stack checking to be done at
+appropriate places in the configuration files, e.g., in
+@code{FUNCTION_PROLOGUE}.  GNU CC will do not other special processing.
+
+@item
+If @code{STACK_CHECK_BUILTIN} is zero and you defined a named pattern
+called @code{check_stack} in your @file{md} file, GNU CC will call that
+pattern with one argument which is the address to compare the stack
+value against.  You must arrange for this pattern to report an error if
+the stack pointer is out of range.
+
+@item
+If neither of the above are true, GNU CC will generate code to periodically
+``probe'' the stack pointer using the values of the macros defined below.
+@end enumerate
+
+Normally, you will use the default values of these macros, so GNU CC
+will use the third approach.
+
+@table @code
+@findex STACK_CHECK_BUILTIN
+@item STACK_CHECK_BUILTIN
+A nonzero value if stack checking is done by the configuration files in a
+machine-dependent manner.  You should define this macro if stack checking 
+is require by the ABI of your machine or if you would like to have to stack 
+checking in some more efficient way than GNU CC's portable approach.
+The default value of this macro is zero.
+
+@findex STACK_CHECK_PROBE_INTERVAL
+@item STACK_CHECK_PROBE_INTERVAL
+An integer representing the interval at which GNU CC must generate stack
+probe instructions.  You will normally define this macro to be no larger
+than the size of the ``guard pages'' at the end of a stack area.  The
+default value of 4096 is suitable for most systems.
+
+@findex STACK_CHECK_PROBE_LOAD
+@item STACK_CHECK_PROBE_LOAD
+A integer which is nonzero if GNU CC should perform the stack probe 
+as a load instruction and zero if GNU CC should use a store instruction.
+The default is zero, which is the most efficient choice on most systems.
+
+@findex STACK_CHECK_PROTECT
+@item STACK_CHECK_PROTECT
+The number of bytes of stack needed to recover from a stack overflow,
+for languages where such a recovery is supported.  The default value of
+75 words should be adequate for most machines.
+
+@findex STACK_CHECK_MAX_FRAME_SIZE
+@item STACK_CHECK_MAX_FRAME_SIZE
+The maximum size of a stack frame, in bytes.  GNU CC will generate probe
+instructions in non-leaf functions to ensure at least this many bytes of
+stack are available.  If a stack frame is larger than this size, stack
+checking will not be reliable and GNU CC will issue a warning.  The
+default is chosen so that GNU CC only generates one instruction on most
+systems.  You should normally not change the default value of this macro.
+
+@findex STACK_CHECK_FIXED_FRAME_SIZE
+@item STACK_CHECK_FIXED_FRAME_SIZE
+GNU CC uses this value to generate the above warning message.  It
+represents the amount of fixed frame used by a function, not including
+space for any callee-saved registers, temporaries and user variables.
+You need only specify an upper bound for this amount and will normally
+use the default of four words.
+
+@findex STACK_CHECK_MAX_VAR_SIZE
+@item STACK_CHECK_MAX_VAR_SIZE
+The maximum size, in bytes, of an object that GNU CC will place in the
+fixed area of the stack frame when the user specifies
+@samp{-fstack-check}.
+GNU CC computed the default from the values of the above macros and you will
+normally not need to override that default.
