2004-01-05 Robert Dewar <dewar@gnat.com>

	* 1ssecsta.ads: Default_Secondary_Stack is not a constant since it may
	be modified by the binder generated main program if the -D switch is
	used.

	* 4onumaux.ads, 4znumaux.ads: Add Pure_Function pragmas for all
	imported functions (since now we expect this to be done for imported
	functions)

	Minor reformatting throughout

	* s-secsta.ads, s-secsta.adb:
	(SS_Get_Max): New function to obtain high water mark for ss stack
	Default_Secondary_Stack is not a constant since it may be modified by
	the binder generated main program if the -D switch is used.

	lib-xref.adb, sem_ch5.adb, sem_ch7.adb, sem_ch8.adb:
	Minor reformatting and code clean ups.
	Minor changes to prevent -gnatwa warnings

	* ali.adb: Minor reformatting and cleanup of code
	Acquire new SS indication of secondary stack use from ali files

	* a-numaux.ads: Add Pure_Function pragmas for all imported functions
	(since now we expect this to be done for imported functions)

	* bindgen.adb: Generate call to modify default secondary stack size if
	-Dnnn switch given

	* bindusg.adb: Add line for new -D switch

	* exp_aggr.adb (Type_May_Have_Bit_Aligned_Components): More appropriate
	replacement name for Type_May_Have_Non_Bit_Aligned_Components!
	Add circuitry for both records and arrays to avoid gigi
	processing if the type involved has non-bit-aligned components

	* exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
	N_String_Literal node always references an E_String_Literal_Subtype
	entity. This may not be true in the future.
	(Possible_Bit_Aligned_Component): Move processing of
	Component_May_Be_Bit_Aligned from exp_ch5 to exp_util

	* exp_ch6.adb (Expand_Thread_Body): Pick up
	Default_Secondary_Stack_Size as variable so that we get value modified
	by possible -Dnnn binder parameter.

	* exp_util.adb (Component_May_Be_Bit_Aligned): New function.
	(Type_May_Have_Bit_Aligned_Components): New function.

	* exp_util.ads (Component_May_Be_Bit_Aligned): New function.
	(Type_May_Have_Bit_Aligned_Components): New function.

	* fe.h: (Set_Identifier_Casing): Fix prototype.
	Add declaration for Sem_Elim.Eliminate_Error_Msg.
	Minor reformatting.

	* freeze.adb (Freeze_Entity): Add RM reference to error message about
	importing constant atomic/volatile objects.
	(Freeze_Subprogram): Reset Is_Pure indication for imported subprogram
	unless explicit Pure_Function pragma given, to avoid insidious bug of
	call to non-pure imported function getting eliminated.

	* gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb,
	gnatls.adb, gnatlink.adb, gnatmem.adb, gnatname.adb, gnatsym.adb,
	gnatxref.adb, gprcmd.adb, gprep.adb, make.adb: Minor reformatting
	Add 2004 to printed copyright notice

	* lib-writ.ads, lib-writ.adb: Put new SS flag in ali file if secondary
	stack used.

	* Makefile.rtl: Add entry for g-sestin.o
	g-sestin.ads: New file.

	* mdll.adb: Minor changes to avoid -gnatwa warnings

	* mlib-tgt.adb: Minor reformatting

	* opt.ads: New parameter Default_Secondary_Stack_Size (GNATBIND)
	New switch Sec_Stack_Used (GNAT, GNATBIND)
	Make Default_Secondary_Stack_Size a variable instead of a constant,
	so that it can be modified by the new -Dnnn bind switch.

	* rtsfind.adb (Load_Fail): Give full error message in configurable
	run-time mode if all_errors mode is set. This was not done in the case
	of a file not found, which was an oversight.
	Note if secondary stack unit is used by compiler.

	* sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
	ineffective elaborate all pragmas on non-visible packages (this
	happened when a renamed subprogram was called). Now the elaborate all
	always goes on the package containing the renaming rather than the one
	containing the renamed subprogram.

	* sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
	(Process_Eliminate_Pragma): Add parameter to capture pragma location.

	* sem_eval.adb (Eval_String_Literal): Do not assume that string literal
	has an Etype that references an E_String_Literal.
	(Eval_String_Literal): Avoid assumption that N_String_Literal node
	always references an E_String_Literal_Subtype entity. This may not
	be true in the future.

	* sem_prag.adb (Process_Eliminate_Pragma): Add parameter to capture
	pragma location.

	* sem_res.adb (Resolve): Specialize msg for function name used in proc
	call.

2004-01-05  Ed Falis  <falis@gnat.com>

	* g-debuti.adb: Replaced direct boolean operator with short-circuit
	form.

2004-01-05  Vincent Celier  <celier@gnat.com>

	* bld.adb: Minor comment updates
	(Process_Declarative_Items): Correct incorrect name (Index_Name instead
	of Item_Name).

	* make.adb (Gnatmake): Special process for files to compile/check when
	-B is specified. Fail when there are only foreign mains in attribute
	Main of the project file and -B is not specified. Do not skip bind/link
	steps when -B is specified.

	* makeusg.adb: Document new switch -B

	* opt.ads (Build_Bind_And_Link_Full_Project): New Boolean flag

	* switch-m.adb: (Scan_Make_Switches): Process -B switch

	* vms_data.ads: Add new GNAT PRETTY qualifier
	/FORM_FEED_AFTER_PRAGMA_PAGE for switch -ff

2004-01-05  Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>

	* trans.c (tree_transform, case N_Free_Statement): Handle thin pointer
	case.

	* misc.c (gnat_printable_name): If VERBOSITY is 2, call
	Set_Identifier_Casing.

	has size that overflows.

	-gnatwa warning on static condition.

2004-01-05  Doug Rupp  <rupp@gnat.com>

	* link.c: (shared_libgnat_default) [VMS]: Change to STATIC.

2004-01-05  Arnaud Charlet  <charlet@act-europe.fr>

	* Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
	all attributes, including read-only attribute.

2004-01-05  Pascal Obry  <obry@gnat.com>

	* bindgen.adb (Gen_Object_Files_Options): Generate the new shared
	library naming scheme.

	* mlib-prj.adb (Build_Library): Generate different names for the static
	or dynamic version of the GNAT runtime. This is needed to support the
	new shared library naming scheme.
	(Process_Binder_File): Add detection of shared library in binder file
	based on the new naming scheme.

	* gnatlink.adb (Process_Binder_File): Properly detect the new naming
	scheme for the shared runtime libraries.

	* Makefile.in:
	(LIBRARY_VERSION) [VMS]: Convert all . to _ to conform to new naming
	scheme.
	(install-gnatlib): Do not create symlinks for shared libraries.
	(gnatlib-shared-default): Idem.
	(gnatlib-shared-dual-win32): New target. Not used for now as the
	auto-import feature does not support arrays/records.
	(gnatlib-shared-win32): Do not create copy for the shared libraries.
	(gnatlib-shared-vms): Fix shared runtime libraries names.

	* osint.ads, osint.adb (Shared_Lib): New routine, returns the target
	dependent runtime shared library name.

2004-01-05  Vasiliy Fofanov  <fofanov@act-europe.fr>

	* osint.adb (Read_Library_Info): Remove bogus check if ALI is older
	than the object.

2004-01-05  Ed Schonberg  <schonberg@gnat.com>

	* sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
	protected objects when allocator has a subtype indication, not a
	qualified expression. Note that qualified expressions may have to be
	checked when limited aggregates are implemented.

	* sem_prag.adb (Analyze_Pragma, case Import): If enclosing package is
	pure, emit warning.
	(Analyze_Pragma, case Pure_Function): If enclosing package is pure and
	subprogram is imported, remove warning.

2004-01-05  Geert Bosch  <bosch@gnat.com>

	* s-poosiz.adb: Update copyright notice.
	(Allocate): Use Task_Lock to protect against concurrent access.
	(Deallocate): Likewise.

2004-01-05  Joel Brobecker  <brobecker@gnat.com>
