2004-06-07  Vincent Celier  <celier@gnat.com>

	* a-calend.ads: Add a GNAT Note comment after function Time_Of to
	explain that when a time of day corresponding to the non existing hour
	on the day switching to DST is specified, Split may return a different
	value for Seconds.

	* gnatcmd.adb: Add processing of GNAT METRIC (for gnatmetric), similar
	to GNAT PRETTY.

	* g-os_lib.adb (OpenVMS): New Boolean value imported from System.
	(Normalize_Pathname): Only resolve VMS logical names when on VMS.

	* mlib-prj.adb (Build_Library): New flag Gtrasymobj_Needed, initialize
	to False.
	If Gtrasymobj_Needed is True, add the full path of g-trasym.obj to
	the linking options.
	(Build_Library.Check_Libs): On VMS, if there is a dependency on
	g-trasym.ads, set Gtrasymobj_Needed to True.

	* prj-attr.adb: Add new package Metrics for gnatmetric

	* prj-nmsc.adb (Record_Other_Sources): Put source file names in
	canonical case to take into account files with upper case characters on
	Windows.
	(Ada_Check): Load the reference symbol file name in the name buffer to
	check it, not the symbol file name.

	* snames.ads, snames.adb: Add standard name Metrics (name of project
	file package for gnatmetric).

	* vms_conv.ads: Add Metric to Comment_Type

	* vms_conv.adb (Initialize): Add component dor Metric in Command_List

	* vms_data.ads: Add qualifiers for GNAT METRIC

	* makegpr.adb (Link_Executables): Take into account the switches
	specified in package Linker of the main project.

2004-06-07  Thomas Quinot  <quinot@act-europe.fr>

	* bindgen.adb (Set_Unit_Number): Units is an instance of Table, and so
	the index of the last element is Units.Last, not Units.Table'Last
	(which is usually not a valid index within the actually allocated
	storage for the table).

	* exp_ch4.adb (Insert_Dereference_Action): Change predicate that
	determines whether to generate a call to a checked storage pool
	Dereference action.
	Generate such a call only for a dereference that either comes from
	source, or is the result of rewriting a dereference that comes from
	source.

2004-06-07  Romain Berrendonner  <berrendo@act-europe.fr>

	* bindgen.adb (Gen_Output_File): Add support for GAP builds.

2004-06-07  Eric Botcazou  <ebotcazou@act-europe.fr>

	(gnat_to_gnu_entity) <E_Array_Subtype>: For multi-dimensional arrays at
	file level, elaborate the stride for inner dimensions in alignment
	units, not bytes.

	* exp_ch5.adb: Correct wrong reference to Component_May_Be_Bit_Aligned
	in a comment.

2004-06-07  Javier Miranda  <miranda@gnat.com>

	* exp_ch6.adb: Correct wrong modification in previous patch

2004-06-07  Vasiliy Fofanov  <fofanov@act-europe.fr>

	* g-trasym.ads: Corrected comment to properly reflect level of support
	on VMS.

2004-06-07  Hristian Kirtchev  <kirtchev@gnat.com>

	* lib-xref.adb (Generate_Reference): Add nested function Is_On_LHS. It
	includes case of a variable referenced on the left hand side of an
	assignment, therefore remove redundant code. Variables and prefixes of
	indexed or selected components are now marked as referenced on left
	hand side. Warnings are now properly emitted when variables or prefixes
	are assigned but not read.

	* sem_warn.adb (Output_Unreferenced_Messages): Add additional checks to
	left hand side referenced variables. Private access types do not
	produce the warning "variable ... is assigned but never read".
	Add also additional checks to left hand side referenced variables.
	Aliased, renamed objects and access types do not produce the warning
	"variable ... is assigned but never read" since other entities may read
	the memory location.

2004-06-07  Jerome Guitton  <guitton@act-europe.fr>

	* Makefile.in: In the powerpc/vxworks-specific section, restore
	EXTRA_GNATRTL_NONTASKING_OBJS and EXTRA_GNATRTL_TASKING_OBJS (removed
	by mistake).

2004-06-07  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch4.adb (Remove_Abstract_Operations): Refine the removal of
	predefined operators.
	Removes spurious type errors from g-trasym-vms.adb.

	* sem_res.adb (Rewrite_Renamed_Operator): If intrinsic operator is
	distinct from the operator appearing in the source, call appropriate
	routine to insert conversions when needed, and complete resolution of
	node.
	(Resolve_Intrinsic_Operator): Fix cut-and-paste bug on transfer of
	interpretations for rewritten right operand.
	(Set_Mixed_Mode_Operand): Handle properly a universal real operand when
	the other operand is overloaded and the context is a type conversion.

2004-06-07  Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>

	* ada-tree.def (BLOCK_STMT): Now has two operands.
	(BREAK_STMT): New.

	* ada-tree.h: (BLOCK_STMT_BLOCK): New macro.

	* gigi.h: (gnat_poplevel): Now returns a tree.

	* trans.c (end_block_stmt): Add arg; all callers changed.
	(tree_transform, case N_Case_Statement): Make a BLOCK_STMT for a WHEN.
	(start_block_stmt): Clear BLOCK_STMT_BLOCK.
	(add_stmt): Set TREE_TYPE.
	(gnat_expand_stmt, case BLOCK_STMT): Handle BLOCK_STMT_BLOCK.
	(gnat_expand_stmt, case BREAK_STMT): New case.

	* utils.c (gnat_poplevel): Return a BLOCK, if we made one.

2004-06-07  Jose Ruiz  <ruiz@act-europe.fr>

	* s-stchop.adsm s-stchop.adb, s-stchop-vxworks.adb: Remove the
	procedure Set_Stack_Size that is not needed.

2004-06-07  Sergey Rybin  <rybin@act-europe.fr>

	* gnat_ugn.texi: Clarify the case when non-standard naming scheme is
	used for gnatpp input file and for the files upon which it depends

2004-06-07  Ben Brosgol  <brosgol@gnat.com>

	* gnat_ugn.texi: Wordsmithing of "GNAT and Libraries" chapter

2004-06-07  Arnaud Charlet  <charlet@act-europe.fr>

	* gnatvsn.ads: Bump version numbers appropriately.
	Add new build type.

2004-06-07  Pascal Obry  <obry@gnat.com>

	* gnat_ugn.texi: Improve comments about imported names and link names
	on Windows. Add a note about the requirement to use -k gnatdll's option
	when working with a DLL which has stripped stdcall symbols (no @nn
	suffix).
