	to not use the PCS in the case where no pragma All_Calls_Remote applies,
	as is already done in the PolyORB implementation of the DSA.

	as is done for non-private derived record types.

	Ada 2005 AI-310: an abstract non-dispatching operation is not a
	candidate interpretation in an overloaded call.

	* tbuild.adb (Unchecked_Convert_To): Preserve conversion node if
	expression is Null and target type is not an access type (e.g. a
	non-private address type).

	* exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
	statement whose right-hand side is an inlined call, save a copy of the
	original assignment subtree to preserve enough consistency for
	Analyze_Assignment to proceed.

	* sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
	complete assignment subtree which is now unnecessary, as the expansion
	of inlined call has been improved to preserve a consistent assignment
	tree.  Note_Possible_Modification must be called only
	after checks have been applied, or else unnecessary checks will
	be generated.

	* sem_util.adb (Note_Possible_Modification): Reorganise the handling
	of explicit dereferences that do not Come_From_Source:
	 - be selective on cases where we must go back to the dereferenced
	   pointer (an assignment to an implicit dereference must not be
	   recorded as modifying the pointer);
	 - do not rely on Original_Node being present (Analyze_Assignment
	   calls Note_Possible_Modification on a copied tree).

	* sem_warn.adb (Check_References): When an unset reference to a pointer
	that is never assigned is encountered, prefer '<pointer> may be null'
	warning over '<pointer> is never assigned a value'.

2004-03-29  Ed Schonberg  <schonberg@gnat.com>

	* exp_ch6.adb (Expand_Call): A call to a function declared in the

2004-03-25  Thomas Quinot  <quinot@act-europe.fr>

	* sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
	attribute reference does not denote a subtype, it can be any
	expression that has a classwide type, potentially after an implicit
	dereference.  In particular, the prefix can be a view conversion for
	a classwide type (for which Is_Object_Reference holds), but it can
	also be a value conversion for an access-to-classwide type. In the
	latter case, there is an implicit dereference, and the original node
	for the prefix does not verify Is_Object_Reference.

	* sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
	conversion of a discriminant-dependent component of a mutable object
	is one itself.

	* sem_elab.adb (Check_Elab_Call): Refine loop that checks for default

	gigi has enough information to construct the record, and there is no
	place in the tree for the declaration.

	* sem_ch6.adb (Build_Body_To_Inline): Use an internal name without

	* decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
	as regular exception objects and not as mere integers representing the
	condition code.  The latter approach required some dynamics to mask off
	severity bits, which did not fit well into the GCC table based model.
	(gnat_to_gnu_entity, objects): Don't supply an external name for VMS
	exception data objects. We don't it and it would conflict with the other
	external symbol we have to generate for such exceptions.

	* trans.c (tree_transform, case N_Exception_Handler): Remove part of

	as regular exceptions objects.

	a dummy empty library).

	* targparm.ads: Configurable_Run_Time mode no longer affects linker

	to indicate that the initialization call corresponds to a
	default-initialized component of an aggregate.
	In case of default initialized aggregate with tasks this parameter is
	used to generate a null string (this is just a workaround that must be
	improved later). In case of discriminants, this parameter is used to
	generate a selected component node that gives access to the discriminant
	value.

	* exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
	subprogram, based on Build_Task_Allocate_Block, but adapted to expand

2003-10-21  Gary Dismukes  <dismukes@gnat.com>

	* exp_ch3.adb:
	(Component_Needs_Simple_Initialization): Return False when the type is a
	packed bit array. Revise spec comments to document this case.

	* exp_prag.adb:
	(Expand_Pragma_Import): Set any expression on the imported object to
	empty to avoid initializing imported objects (in particular this
	covers the case of zero-initialization of bit arrays).
	Update copyright notice.

2003-10-21  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch12.adb:
	(Load_Parent_Of_Generic): If parent is compilation unit, stop search,
	a subunit is missing.
	(Instantiate_Subprogram_Body): If body of function is missing, set type
	of return expression explicitly in dummy body, to prevent cascaded
	errors when a subunit is missing.
	Fixes PR 5677.

	* sem_ch3.adb:
	(Access_Subprogram_Declaration): Verify that return type is valid.
	Fixes PR 8693.

	* sem_elab.adb:
	(Check_Elab_Calls): Do not apply elaboration checks if the main unit is
	generic.
	Fixes PR 12318.

	* sem_util.adb:
	(Corresponding_Discriminant): If the scope of the discriminant is a
	private type without discriminant, use its full view.
	Fixes PR 8247.

	* exp_ch7.adb (Make_Transient_Block): if statement is within
	exception handler, always use new transient scope to place Clean
	procedure.

2001-10-11  Pascal Obry <obry@gnat.com>

	* Makefile.in:
	(GNAT_ADA_OBJS): add g-crc32.o, a-tags.o, a-stream.o
	(GNATBIND_OBJS): add g-crc32.o, a-tags.o, a-stream.o
	(GNATLS_RTL_OBJS): add g-crc32.o
	(GNATMAKE_RTL_OBJS): add g-crc32.o

	* ali-util.adb:
	(CRC_Match): new function.
	(Get_File_Checksum): renamed Get_File_CRC. Use the GNAT.CRC32 unit
	instead of the previous simple checksum algorithm.
	(Time_Stamp_Mismatch): use CRC_Match for comparison.
	(Set_Source_Table): idem.

	* ali-util.ads:
	(Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
	instead of simple checksum.
	(CRC_Match): new function.
	(CRC_Error): new constant.

	* ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
	a CRC now and not a simple checksum. A CRC uses lower-case hex
	letters, fixes ambiguity in parsing.

	* ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
	is what this variable will store.

	* bcheck.adb: Change reference to chechsum in comments by CRC.
	(Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
	rename All_Checksum_Match to All_CRC_Match. Change due to API
	renaming since now GNAT does not use a simple checksum but a
	CRC using GNAT.CRC32.

	* gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
	now and not anymore a simple checksum.

	* lib-load.adb: Use Source_CRC instead of Source_Checksum in many
	places.

	* lib-writ.adb (Write_ALI): Use Source_CRC instead of Source_Checksum.

	* scans.adb:
	(Restore_Scan_State): rename Checksum to CRC.
	(Save_Scan_State): idem.

	* scans.ads:
	With GNAT.CRC32.
	(Checksum): rename to CRC.
	(Saved_Scan_State): Save_Checksum field renamed to Save_CRC

	* scn-nlit.adb: Rename many Accumulate_Checksum to Update (from
	GNAT.CRC32).  Update copyright notice.

	* scn-slit.adb: Rename many Accumulate_Checksum to Update (from
	GNAT.CRC32).  Update copyright notice.

	* scn.adb:
	(Accumulate_Checksum): removed.

	(Complete_Source_File_Entry): use CRC32 instead of simple checksum.
	(Load_File): fix initialization of S (change Source_Checksum to
	Source_CRC)

	* sinput-p.adb (Load_Project_File): rename Source_Checksum to
	Source_CRC in S initialization.

	* sinput.adb (Source_Checksum): renamed to Source_CRC.

	* sinput.ads (Source_Checksum): renamed to Source_CRC.
	Update comments for the CRC.

	* types.adb (Hex): Use lowercase for the letter part.

	* types.ads (Get_Hex_String): Returns the hexadecimal representation
	for a word. This is currently used only for CRC. In previous version,
	the checksum was using a representation with all letter being
	upper-case. With the new implementation (using CRC) we do not remove
	the 32th bit of the CRC, so we can have an upper-case starting letter
	in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
	It is ambigous since the CRC was optional and could be followed by
	options like EB, EE. So now this routines uses lower-case letter for
	the hexadecimal representation. Strange enough only lower case letters
	where checked in Scan_ALI (even if this was not a possible case).

	* gnatvsn.ads (Library_Version): changed to 3.15a.

	* s-crc32.ads: Initial version from GNAT.CRC32. This is the version
	for the compiler.

	* s-crc32.adb: Initial version from GNAT.CRC32. This is the version
	for the compiler.

	* ali-util.adb: Redo previous change to avoid using word CRC everywhere
	Add 2001 to copyright notice
	(Accumulate_Checksum): Modify to use System.CRC32.

	* ali-util.ads: Redo changes of previous revision to continue to use
	the word Checksum. Add 2001 to copyright notice.

	* ali.adb: Undo some of previous changes, not needed.
	Keep the change for lower case letters in the checksum.

	* ali.ads: Undo previous change not needed.

	* bcheck.adb: Undo most of previous change, not needed.
	But do use Checksums_Match for checksum comparison.

	* gnatls.adb: Undo most of previous change, not needed.
	But do use Checksums_Match for comparing checksums.

	* lib-load.adb: Undo previous change, not needed.

	* lib-writ.adb: Undo previous change, not needed.

	* lib-writ.ads: Document that checksums use lower case,
	not upper case letters.

	* scans.adb: Undo previous change, not needed

	* scans.ads: Undo previous change, not needed.

	* scn-nlit.adb: Undo previous changes, not needed.

	* sinput.adb: Undo previous change, not needed.

	* sinput-l.adb: Undo previous change, not needed.

	* sinput.ads: Undo previous change, not needed.  Keep only comment
	on new checksum algorithm

	* Makefile.in: Add s-crc32 as needed, remove g-crc32.
	Also remove a-tags and a-stream from GNAT sources.

	* ali.adb (Scan_ALI): fix typo introduce in latest check-in.

	* Makefile.in (GNATRTL_NONTASKING_OBJS): Add g-crc32.o.
