	* 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.
	(Timed_Task_Entry_Call): When pragma Detect_Blocking is active, raise
	Program_Error if called from a protected operation.

	* s-tassta.adb (Abort_Tasks): When pragma Detect_Blocking is active,
	raise Program_Error if called from a protected operation.

	* s-tpoben.adb (Lock_Entries): When pragma Detect_Blocking is active,
	raise Program_Error if called from a protected operation, and increase
	the protected action nesting level.

	(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

	(__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.

	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

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

	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.

	interpretations for rewritten right operand.
	(Set_Mixed_Mode_Operand): Handle properly a universal real operand when
