GCC used to stand for the GNU C - Compiler, but since the compiler supports several other languages - aside from C, it now stands for the GNU Compiler Collection. - - This is a minor release to address several bugs in the GCC version - 2.95.1 release. - - The -fstrict-aliasing is not enabled by default for GCC 2.95.2. While - the optimizations performed by -fstrict-aliasing are valid according - to the C and C++ standards, the optimization have caused some - problems, particularly with old non-conforming code. - - The GCC developers are experimenting with ways to warn users about - code which violates the C/C++ standards, but those warnings are not - ready for widespread use at this time. Rather than wait for those - warnings the GCC developers have chosen to disable -fstrict-aliasing - by default for the GCC 2.95.2 release. - - We strongly encourage developers to find and fix code which violates - the C/C++ standards as -fstrict-aliasing may be enabled by default in - future releases. Use the option -fstrict-aliasing to re-enable these - optimizations. - - * Generic bugfixes and improvements - + Fix incorrectly optimized memory reference in global common - subexpression elimination (GCSE) optimization pass. - + Fix code generation bug in regmove.c in which it could - incorrectly change a "const" value. - + Fix bug in optimization of conditionals involving volatile - memory references. - + Avoid over-allocation of stack space for some procedures. - + Fixed bug in the compiler which caused incorrect optimization - of an obscure series of bit manipulations, shifts and - arithmetic. - + Fixed register allocator bug which caused teTeX to be - mis-compiled on Sparc targets. - + Avoid incorrect optimization of degenerate case statements - for certain targets such as the ARM. - + Fix out of range memory reference in the jump optimizer. - + Avoid dereferencing null pointer in fix-header. - + Fix test for GCC specific features so that it is possible to - bootstrap with gcc-2.6.2 and older versions of GCC. - + Fix typo in scheduler which could potentially cause out of - range memory accesses. - + Avoid incorrect loop reversal which caused incorrect code for - certain loops on PowerPC targets. - + Avoid incorrect optimization of switch statements on certain - targets (for example the ARM). - * Platform specific bugfixes and improvements - + Work around bug in Sun V5.0 compilers which caused bootstrap - comparison failures on Sparc targets. - + Fix Sparc backend bug which caused aborts in final.c. - + Fix sparc-hal-solaris2* configuration fragments. - + Fix bug in sparc block profiling. - + Fix obscure code generation bug for the PARISC targets. - + Define __STDC_EXT__ for HPUX configurations. - + Various POWERPC64 code generation bugfixes. - + Fix abort for PPC targets using ELF (ex GNU/Linux). - + Fix collect2 problems for AIX targets. - + Correct handling of .file directive for PPC targets. - + Fix bug in fix_trunc x86 patterns. - + Fix x86 port to correctly pop the FP stack for functions that - return structures in memory. - + Fix minor bug in strlen x86 pattern. - + Use stabs debugging instead of dwarf1 for x86-solaris - targets. - + Fix template repository code to handle leading underscore in - mangled names. - + Fix weak/weak alias support for OpenBSD. - + GNU/Linux for the ARM has C++ compatible include files. - * Language & Runtime specific fixes. - + Fix handling of constructor attribute in the C front-end - which caused problems building the Chill runtime library on - some targets. - + Fix minor problem merging type qualifiers in the C front-end. - + Fix aliasing bug for pointers and references (C/C++). - + Fix incorrect "non-constant initializer bug" when - -traditional or -fwritable-strings is enabled. - + Fix build error for Chill front-end on SunOS. - + Do not complain about duplicate instantiations when using - -frepo (C++) - + Fix array bounds handling in C++ front-end which caused - problems with dwarf debugging information in some - circumstances. - + Fix minor namespace problem. - + Fix problem linking java programs. - - The whole suite has been extensively [1]regression tested and - [2]package tested.

This - is particularly noticeable when compiling older versions of the - Linux kernel (2.0.xx). Please refer to the [1]FAQ for more - information on this issue. - * GCC 2.95 implements type based alias analysis to disambiguate - memory references. Some programs, particularly the Linux kernel - violate ANSI/ISO aliasing rules and therefore may not operate - correctly when compiled with GCC 2.95. Please refer to the [2]FAQ - for more information on this issue. - * GCC 2.95 has a known bug in its handling of complex variables for - 64bit targets. Instead of silently generating incorrect code, GCC - 2.95 will issue a fatal error for situations it can not handle. - This primarily affects the Fortran community as Fortran makes more - use of complex variables than C or C++. - * GCC 2.95 has an integrated libstdc++, but does not have an - integrated libg++. Furthermore old libg++ releases will not work - with GCC 2.95. You can retrieve a recent copy of libg++ from the - [3]GCC ftp server. - Note most C++ programs only need libstdc++. - * Exception handling may not work with shared libraries, - particularly on alphas, hppas, rs6000/powerpc and mips based - platforms. Exception handling is known to work on x86 GNU/Linux - platforms with shared libraries. - * In general, GCC 2.95 is more rigorous about rejecting invalid C++ - code or deprecated C++ constructs than G++ 2.7, G++ 2.8, EGCS 1.0, - or EGCS 1.1. As a result it may be necessary to fix C++ code - before it will compile with GCC 2.95. - * G++ is also converting toward the ISO C++ standard; as a result - code which was previously valid (and thus accepted by other - compilers and older versions of g++) may no longer be accepted. - The flag -fpermissive may allow some non-conforming code to - compile with GCC 2.95. - * GCC 2.95 compiled C++ code is not binary compatible with EGCS - 1.1.x, EGCS 1.0.x or GCC 2.8.x. - * GCC 2.95 does not have changes from the GCC 2.8 tree that were - made between Sept 30, 1998 and April 30, 1999 (the official end of - the GCC 2.8 project). Future GCC releases will include all the - changes from the defunct GCC 2.8 sources. - _________________________________________________________________ - - - [4]The GCC team - Last modified 2000-11-10 - -References - - 1. http://gcc.gnu.org/faq.html#asmclobber - 2. http://gcc.gnu.org/fom_serv/cache/24.html - 3. ftp://gcc.gnu.org/pub/gcc/infrastructure/libg++-2.8.1.3.tar.gz - 4. http://gcc.gnu.org/about.html -====================================================================== -http://gcc.gnu.org/egcs-1.1/egcs-1.1.2.html - - EGCS 1.1.2 - - March 15, 1999 - - We are pleased to announce the release of EGCS 1.1.2. - - EGCS is a collaborative effort involving several groups of hackers - using an open development model to accelerate development and testing - of GNU compilers and runtime libraries. - - EGCS 1.1.2 is a minor update to the EGCS 1.1.1 compiler to fix several - serious problems in EGCS 1.1.1. - * General improvements and fixes - + Fix bug in loop optimizer which caused the SPARC (and - potentially other) ports to segfault. - + Fix infinite recursion in alias analysis and combiner code. - + Fix bug in regclass preferencing. - + Fix incorrect loop reversal which caused incorrect code to be - generated for several targets. - + Fix return value for builtin memcpy. - + Reduce compile time for certain loops which exposed quadratic - behavior in the loop optimizer. - + Fix bug which caused volatile memory to be written multiple - times when only one write was needed/desired. - + Fix compiler abort in caller-save.c - + Fix combiner bug which caused incorrect code generation for - certain division by constant operations. - + Fix incorrect code generation due to a bug in range check - optimizations. - + Fix incorrect code generation due to mis-handling of - clobbered values in CSE. - + Fix compiler abort/segfault due to incorrect register - splitting when unrolling loops. - + Fix code generation involving autoincremented addresses with - ternary operators. - + Work around bug in the scheduler which caused qt to be - mis-compiled on some platforms. - + Fix code generation problems with -fshort-enums. - + Tighten security for temporary files. - + Improve compile time for codes which make heavy use of - overloaded functions. - + Fix multiply defined constructor/destructor symbol problems. - + Avoid setting bogus RPATH environemnt variable during - bootstrap. - + Avoid GNU-make dependencies in the texinfo subdir. - + Install CPP wrapper script in $(prefix)/bin if --enable-cpp. - --enable-cpp= can be used to specify an additional install - directory for the cpp wrapper script. - + Fix CSE bug which caused incorrect label-label refs to appear - on some platforms. - + Avoid linking in EH routines from libgcc if they are not - needed. - + Avoid obscure bug in aliasing code. - + Fix bug in weak symbol handling. - * Platform-specific improvements and fixes - + Fix detection of PPro/PII on Unixware 7. - + Fix compiler segfault when building spec99 and other programs - for SPARC targets. - + Fix code-generation bugs for integer and floating point - conditional move instructions on the PPro/PII. - + Use fixincludes to fix byteorder problems on i?86-*-sysv. - + Fix build failure for the arc port. - + Fix floating point format configuration for i?86-gnu port - + Fix problems with hppa1.0-hp-hpux10.20 configuration when - threads are enabled - + Fix coldfire code generation bugs. - + Fix "unrecognized insn" problems for Alpha and PPC ports. - + Fix h8/300 code generation problem with floating point values - in memory. - + Fix unrecognized insn problems for the m68k port. - + Fix namespace-pollution problem for the x86 port. - + Fix problems with old assembler on x86 NeXT systems. - + Fix PIC code-generation problems for the SPARC port. - + Fix minor bug with LONG_CALLS in PowerPC SVR4 support. - + Fix minor ISO namespace violation in Alpha varargs/stdarg - support. - + Fix incorrect "braf" instruction usage for the SH port. - + Fix minor bug in va-sh which prevented its use with -ansi. - + Fix problems recognizing and supporting FreeBSD. - + Handle OpenBSD systems correctly. - + Minor fixincludes fix for Digital UNIX 4.0B. - + Fix problems with ctors/dtors in SCO shared libraries. - + Abort instead of generating incorrect code for PPro/PII - floating point conditional moves. - + Avoid multiply defined symbols on Linux/GNU systems using - libc-5.4.xx. - + Fix abort in alpha compiler. - - Fortran-specific fixes - * Fix the IDate intrinsic (VXT) (in libg2c) so the returned year is - in the documented, non-Y2K-compliant range of 0-99, instead of - being returned as 100 in the year 2000. - * Fix the `Date_and_Time' intrinsic (in libg2c) to return the - milliseconds value properly in Values(8). - * Fix the `LStat' intrinsic (in libg2c) to return device-ID - information properly in SArray(7). - - An important goal of EGCS is to allow wide scale testing of new - features and optimizations which are still under development. However, - EGCS has been carefully tested and should be comparable in quality to - most gcc releases. - - EGCS 1.1.2 is based on the June 6, 1998 snapshot of the GCC 2.8 - development sources; it contains all of the new features found in GCC - 2.8.1 as well as all new development from gcc2 up to June 6, 1998. - - See the [1]new features page for a more complete list of new features - found in EGCS 1.1 releases. - - The EGCS 1.1.2 release includes installation instructions in both HTML - and plaintext forms (see the INSTALL directory in the toplevel - directory of the EGCS 1.1.2 distribution).

By providing more accurate information - to the priority based allocator, we get better register - allocation. - * The register reloading phase of the compiler optimizes spill code - much better than in previous releases. - * Some bad interactions between the register allocator and - instruction scheduler have been fixed, resulting in much better - code for certain programs. Additionally, we have tuned the - scheduler in various ways to improve performance of generated code - for some architectures. - * The compiler's branch shortening algorithms have been - significantly improved to work better on targets which align jump - targets. - * The compiler now supports -Os to prefer optimizing for code space - over optimizing for code speed. - * The compiler will now totally eliminate library calls which - compute constant values. This primarily helps targets with no - integer div/mul support and targets without floating point - support. - * The compiler now supports an extensive "--help" option. - * cpplib has been greatly improved and may be suitable for limited - use. - * Memory footprint for the compiler has been significantly reduced - for some pathological cases. - * The time to build EGCS has been improved for certain targets - (particularly the alpha and mips platforms). - * Many infrastructure improvements throughout the compiler, plus the - usual mountain of bugfixes and minor improvements. - * Target dependent improvements: - + SPARC port now includes V8 plus and V9 support as well as - performance tuning for Ultra class machines. The SPARC port - now uses the Haifa scheduler. - + Alpha port has been tuned for the EV6 processor and has an - optimized expansion of memcpy/bzero. The Alpha port now uses - the Haifa scheduler. - + RS6000/PowerPC: EGCS 1.1 includes support for the Power64 - architecture and aix4.3 support. The RS6000/PowerPC port now - uses the Haifa scheduler. - + x86: Alignment of static store data and jump targets is per - Intel recommendations now. Various improvements throughout - the x86 port to improve performance on Pentium processors. - Conditional move support has been fixed and enabled for PPro - processors. The x86 port also better supports 64bit - operations now. - + MIPS has improved multiply/multiply-add support and now - includes mips16 ISA support. - + M68k has many micro-optimizations and Coldfire fixes. - * Core compiler is based on the GCC development tree from June 9, - 1998, so we have all of the [5]features found in GCC 2.8. - - [6]Return to the EGCS home page - - Last modified: September 4, 1999 - -References - - 1. http://gcc.gnu.org/onlinedocs/g77_news.html - 2. http://gcc.gnu.org/egcs-1.1/c++features.html - 3. http://gcc.gnu.org/news/gcse.html - 4. http://gcc.gnu.org/news/alias.html - 5. http://gcc.gnu.org/egcs-1.0/features-2.8.html - 6. http://gcc.gnu.org/index.html -====================================================================== -http://gcc.gnu.org/egcs-1.1/caveats.html - - EGCS 1.1 Caveats - - * EGCS has an integrated libstdc++, but does not have an integrated - libg++.

Changes since the - EGCS 1.0 release: - * Add support for Red Hat 5.0 Linux and better support for Linux - systems using glibc2. - Many programs failed to link when compiled with EGCS 1.0 on Red - Hat 5.0 or on systems with newer versions of glibc2. EGCS 1.0.1 - should fix these problems. - * Compatability with both EGCS 1.0 and GCC 2.8 libgcc exception - handling interfaces. - To avoid future compatibility problems, we strongly urge anyone - who is planning on distributing shared libraries that contain C++ - code to upgrade to EGCS 1.0.1 first. - Soon after EGCS 1.0 was released, the GCC developers made some - incompatible changes in libgcc's exception handling interfaces. - These changes were needed to solve problems on some platforms. - This means that GCC 2.8.0, when released, will not be seamlessly - compatible with shared libraries built by EGCS 1.0. The reason is - that the libgcc.a in GCC 2.8.0 will not contain a function needed - by the old interface. - The result of this is that there may be compatibility problems - with shared libraries built by EGCS 1.0 when used with GCC 2.8.0. - With EGCS 1.0.1, generated code uses the new (GCC 2.8.0) - interface, and libgcc.a has the support routines for both the old - and the new interfaces (so EGCS 1.0.1 and EGCS 1.0 code can be - freely mixed, and EGCS 1.0.1 and GCC 2.8.0 code can be freely - mixed). - The maintainers of GCC 2.x have decided against including seamless - support for the old interface in 2.8.0, since it was never - "official", so to avoid future compatibility problems we recommend - against distributing any shared libraries built by EGCS 1.0 that - contain C++ code (upgrade to 1.0.1 and use that). - * Various bugfixes in the x86, hppa, mips, and rs6000/ppc backends. - The x86 changes fix code generation errors exposed when building - glibc2 and the Linux dynamic linker (ld.so). - The hppa change fixes a compiler abort when configured for use - with RTEMS. - The MIPS changes fix problems with the definition of LONG_MAX on - newer systems, allow for command line selection of the target ABI, - and fix one code generation problem. - The rs6000/ppc change fixes some problems with passing structures - to varargs/stdarg functions. - * A few machine independent bugfixes, mostly to fix code generation - errors when building Linux kernels or glibc. - * Fix a few critical exception handling and template bugs in the C++ - compiler. - * Fix Fortran namelist bug on alphas. - * Fix build problems on x86-solaris systems. - - An important goal of EGCS is to allow wide scale testing of new - features and optimizations which are still under development. However, - EGCS has been carefully tested and should be comparable in quality to - most GCC releases. - - EGCS 1.0.1 is based on an August 2, 1997 snapshot of the GCC 2.8 - development sources; it contains nearly all of the new features found - in GCC 2.8. - - EGCS also contains many improvements and features not found in GCC 2.7 - and even the soon to be released GCC 2.8 compilers. - * Integrated C++ runtime libraries, including support for most major - linux systems! - * The integrated libstdc++ library includes a verbatim copy of - [1]SGI's STL release. - * Integrated GNU Fortran compiler - * New instruction scheduler - * New alias analysis code - - See the [2]new features page for a more complete list of new features - found in EGCS 1.0.x releases. - - The EGCS 1.0.1 release includes installation instructions in both HTML - and plaintext forms (see the INSTALL directory in the toplevel - directory of the EGCS 1.0.1 distribution).

However, - EGCS has been carefully tested and should be comparable in quality to - most GCC releases. - - EGCS 1.0 is based on an August 2, 1997 snapshot of the GCC 2.8 - development sources; it contains nearly all of the new features found - in GCC 2.8. - - EGCS 1.0 also contains many improvements and features not found in GCC - 2.7 and even the soon to be released GCC 2.8 compilers. - * Integrated C++ runtime libraries, including support for most major - linux systems! - * The integrated libstdc++ library includes a verbatim copy of - [1]SGI's STL release. - * Integrated GNU Fortran compiler - * New instruction scheduler - * New alias analysis code - - See the [2]new features page for a more complete list of new features. - - The EGCS 1.0 release includes installation instructions in both HTML - and plaintext forms (see the INSTALL directory in the toplevel - directory of the EGCS 1.0 distribution). However, we also keep the - most up to date [3]installation instructions and [4]build/test status - on our web page. We will update those pages as new information becomes - available. - - And, we can't in good conscience fail to mention some [5]caveats to - using EGCS. - - Update: The T1 into our main California offices has been 100% - saturated since shortly after the release. We've added an EGCS 1.0 - mirror at our Massachusetts office to help share the load. We also - encourage folks to use the many mirrors available throughout the - world. - - Update: Big thanks to Stanford for providing a high speed link for - downloading EGCS!

Furthermore old libg++ releases will not work with egc; HJ - Lu has made a [1]libg++ snapshot available which may work with - EGCS. - Note most C++ programs only need libstdc++. - * Note that using -pedantic or -Wreturn-type can cause an explosion - in the amount of memory needed for template-heavy C++ code, such - as code that uses STL. Also note that -Wall includes - -Wreturn-type, so if you use -Wall you will need to specify - -Wno-return-type to turn it off. - * Exception handling may not work with shared libraries, - particularly on alphas, hppas, and mips based platforms. Exception - handling is known to work on x86-linux platforms with shared - libraries. - * Some versions of the Linux kernel have bugs which prevent them - from being compiled or from running when compiled by EGCS. See - [2]the FAQ for additional information. - * In general, EGCS is more rigorous about rejecting invalid C++ code - or deprecated C++ constructs than G++ 2.7. As a result it may be - necessary to fix C++ code before it will compile with EGCS. - * G++ is also aggressively tracking the C++ standard; as a result - code which was previously valid (and thus accepted by other - compilers and older versions of G++) may no longer be accepted. - * EGCS 1.0 may not work with Red Hat Linux 5.0 on all targets. EGCS - 1.0.x and later releases should work with Red Hat Linux 5.0. - - [3]Return to the GCC home page - - Last modified: August 27, 1998 - -References - - 1. ftp://ftp.yggdrasil.com/private/hjl/libg++-2.8.1.2.tar.gz - 2. http://gcc.gnu.org/faq.html#linuxkernel - 3. http://gcc.gnu.org/index.html -====================================================================== |
