+
+2004-09-09 Jose Ruiz <ruiz@act-europe.fr>
+
+ * gnat_ugn.texi: Add Detect_Blocking to the list of configuration
+ pragmas recognized by GNAT.
+
+ * gnat_rm.texi: Document pragma Detect_Blocking.
+
+ * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
+ raise Program_Error if called from a protected operation.
+
+ * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
+ the protected action nesting level.
+ (Lock_Read_Only): When pragma Detect_Blocking is active increase the
+ protected action nesting level.
+ (Unlock): When pragma Detect_Blocking is active decrease the protected
+ action nesting level.

+ * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
+ Protected_Action_Nesting.
+
+ * s-taskin.ads: Adding the field Protected_Action_Nesting to the
+ Common_ATCB record. It contains the dynamic level of protected action
+ nesting for each task. It is needed for checking whether potentially
+ blocking operations are called from protected operations.
+ (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
+ Detect_Blocking is active or not in the partition.
+
+ * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
+ raise Program_Error if called from a protected operation.
+ (Task_Entry_Call): When pragma Detect_Blocking is active, raise
+ Program_Error if called from a protected operation.

+ active, raise Program_Error if called from a protected operation.
+ (Unlock_Entry): When pragma Detect_Blocking is active decrease the
+ protected action nesting level.
+
+ * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
+ insertion of the statement raising Program_Error. The run time
+ contains the required machinery for handling that.
+
+ * sem_util.ads: Change comment associated to procedure
+ Check_Potentially_Blocking_Operation.
+ This procedure does not insert a call for raising the exception because
+ that is currently done by the run time.
+
+ * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
+
+ * init.c: Add the global variable __gl_detect_blocking that indicates
+ whether pragma Detect_Blocking is active (1) or not (0). Needed for
+ making the pragma available at run time.
+ (__gnat_set_globals): Pass and update the detect_blocking parameter.
+
+ * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
+ pragma Detect_Blocking is active.
+
+ * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
+
+ * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
+ DB is found in the ali file. Any unit compiled with pragma
+ Detect_Blocking active forces its effect in the whole partition.
+
+ * a-retide.adb (Delay_Until): Raise Program_Error if pragma
+ Detect_Blocking is active and delay is called from a protected
+ operation.
+
+ * bindgen.adb (Gen_Adainit_Ada): When generating the call to
+ __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
+ Detect_Blocking is active (0 otherwise).
+ (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
+ as Detect_Blocking parameter if pragma Detect_Blocking is active (0
+ otherwise).
+
+2004-09-09 Thomas Quinot <quinot@act-europe.fr>
+
+ * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
+ GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
+ package.
+
+ * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
+ (Register_Receiving_Stub): Add Subp_Info formal parameter.
+ Update API in placeholder implemetation of s-parint to reflect changes
+ in distribution runtime library.
+
+ * sem_ch3.adb (Expand_Derived_Record): Rename to
+ Expand_Record_Extension.
+
+ * sem_disp.adb (Check_Controlling_Formals): Improve error message for
+ primitive operations of potentially distributed object types that have
+ non-controlling anonymous access formals.
+
+ * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
+ subprogram.
+ New implementation of expansion for remote access-to-subprogram types,
+ based on the RACW infrastructure.
+ This version of sem_dist is compatible with PolyORB/DSA as well as
+ GLADE.
+
+ * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
+ Asynchrronous that applies to a remote access-to-subprogram type, mark
+ the underlying RACW type as asynchronous.
+
+ * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
+ __gnat_using_gnu_linker to 1.
+
+ * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
+ g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
+ GNAT.Perfect_Hash_Generators, and remove the empty
+ GNAT.Perfect_Hash package.
+
+ * atree.adb: Minor reformatting
+
+ * exp_ch3.adb (Expand_Derived_Record): Rename to
+ Expand_Record_Extension.
+ (Build_Record_Init_Proc.Build_Assignment): The default expression in
+ a component declaration must remain attached at that point in the
+ tree so New_Copy_Tree copies it if the enclosing record type is derived.
+ It is therefore necessary to take a copy of the expression when building
+ the corresponding assignment statement in the init proc.
+ As a side effect, in the case of a derived record type, we now see the
+ original expression, without any rewriting that could have occurred
+ during expansion of the ancestor type's init proc, and we do not need
+ to go back to Original_Node.
+
+ * exp_ch3.ads (Expand_Derived_Record): Rename to
+ Expand_Record_Extension.
+
+ * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
+ Returns the RACW type used to implement a remote access-to-subprogram
+ type.
+ (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
+ New subprograms. Used to create a proxy tagged object for a remote
+ subprogram. The proxy object is used as the designated object
+ for RAS values on the same partition (unless All_Calls_Remote applies).
+ (Build_Get_Unique_RP_Call): New subprogram. Build a call to
+ System.Partition_Interface.Get_Unique_Remote_Pointer.
+ (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
+ Renamed from Add_RAS_*_Attribute.
+ (Add_Receiving_Stubs_To_Declarations): Generate a table of local
+ subprograms.
+ New implementation of expansion for remote access-to-subprogram types,
+ based on the RACW infrastructure.
+
+ * exp_dist.ads (Copy_Specification): Update comment to note that this
+ function can copy the specification from either a subprogram
+ specification or an access-to-subprogram type definition.
+
+2004-09-09 Ed Schonberg <schonberg@gnat.com>
+
+ * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
+ in an instance, between an explicit subprogram an one inherited from a
+ type derived from an actual.
+
+ * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
+ add a polling call if the subprogram is to be inlined by the back-end,
+ to avoid repeated calls with multiple inlinings.
+
+ * checks.adb (Apply_Alignment_Check): If the expression in the address
+ clause is a call whose name is not a static entity (e.g. a dispatching
+ call), treat as dynamic.
+
+2004-09-09 Robert Dewar <dewar@gnat.com>
+
+ * g-trasym.ads: Minor reformatting
+
+ * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except
+ packed arrays, since unused bits are expected to be zero for a
+ comparison.
+
+2004-09-09 Eric Botcazou <ebotcazou@act-europe.fr>
+
+ * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
+ comment.
+
+2004-09-09 Pascal Obry <obry@gnat.com>
+
+ * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
+ enable map file generation. Add the right option to generate the map
+ file if Map_File is set to True.
+
+ * gnatdll.adb (Gen_Map_File): New variable.
+ (Syntax): Add info about new -m (Map_File) option.
+ (Parse_Command_Line): Add support for -m option.
+ (gnatdll): Pass Gen_Map_File to Build_Dynamic_Library calls.
+ Minor reformatting.
+
+2004-09-09 Laurent Pautet <pautet@act-europe.fr>
+
+ * gnatls.adb: Add a very verbose mode -V. Such mode is required by the
+ new gnatdist implementation.
+ Define a subpackage isolating the output routines specific to this
+ verbose mode.
+
+2004-09-09 Joel Brobecker <brobecker@gnat.com>
+
+ * Makefile.rtl: (GNATRTL_NONTASKING_OBJS): Add g-dynhta.
+
+ * gnat_ugn.texi (Main Subprograms): Fix typo. Deduced, not deducted.
+
+2004-09-09 Cyrille Comar <comar@act-europe.fr>
+
+ * opt.adb (Set_Opt_Config_Switches): Use Ada_Version_Runtime to compile
+ internal unit.
+
+ * opt.ads: Add Ada_Version_Runtime constant used to decide which
+ version of the language is used to compile the run time.
+
+2004-09-09 Arnaud Charlet <charlet@act-europe.fr>
+
+ * sem_util.adb (Requires_Transient_Scope): Re-enable handling
+ of variable length temporaries for function return now that the
+ back-end and gigi support it.
