864a4236aa atree.ads, atree.adb (Copy_Separate_List): New function that applies Copy_Separate_Tree to a list of nodes. 
2011-08-29  Ed Schonberg  <schonberg@adacore.com>

	* atree.ads, atree.adb (Copy_Separate_List): New function that applies
	Copy_Separate_Tree to a list of nodes. Used to create disjoint copies
	of statement lists that may contain local declarations.
	(Expand_N_Timed_Entry_Call): Use Copy_Separate_List to duplicate the
	triggering statements needed for the expansion of this construct, when
	the trigger is a dispatching call to a synchronized primitive.

df3e68b121 a-except.adb, [...] (Raise_From_Controlled_Operation): Rewritten to create the message strings when... 
2011-08-03  Hristian Kirtchev  <kirtchev@adacore.com>

	* a-except.adb, a-except-2005.adb (Raise_From_Controlled_Operation):
	Rewritten to create the message strings when the exception is not
	raised by an abort during finalization.
	* a-except.ads, a-except-2005.ads: Add pragma Export for procedure
	Raise_From_Controlled_Operation and update its associated comment.
	* a-fihema.ads, a-fihema.adb: New GNAT unit.
	Ada.Finalization.Heap_Management provides key functionality
	associated with controlled objects on the heap, their creation,
	finalization and reclamation. Type Finalization_Collection is
	effectively a wrapper which sits ontop of a storage pool and performs
	all necessary bookkeeping for all the objects it contains. Each
	access-to-controlled or access-to-class-wide type receives a collection
	as part of its expansion. The compiler generates buffer code and
	invokes Allocate / Deallocate to create and destroy allocated
	controlled objects.
	* a-finali.adb ("="): Removed.
	* a-finali.ads ("="): Removed. Controlled types no longer carry hidden
	fields Prev and Next.
	* ali.adb (Scan_ALI): Add parsing code to process PF / Has_Finalizer.
	A library unit with at least one controlled object on the library level
	has a special finalizer which is invoked by the binder. To signal this,
	ali files carry field PF.
	* ali.ads: New field in type Unit_Record called Has_Finalizer. Add
	associated comment on field usage.
	* a-tags.adb (Get_RC_Offset): Removed.
	(Needs_Finalization): New routine.
	* a-tags.ads: Update the structure of the GNAT dispatch tables.
	Dispatch tables now carry field Needs_Finalization which provides
	runtime indication whether a type is controlled or has controlled
	components or both. Remove field RC_Offset.
	(Get_RC_Offset): Removed along with its associated pragma Export.
	Since tagged types with controlled components no longer carry hidden
	field _controller, the special mechanism to retrieve its location is no
	longer needed.
	(Needs_Finalization): New routine.
	* atree.ads, atree.adb (Elist24): New routine.
	(Set_Elist24): New routine.
	* atree.h: Add a define clause for Elist24.
	* bindgen.adb New library-level variable Lib_Final_Built.

	presence of a VM target, the routine generates calls to the proper
	library finalization routine.

	targets. Set the correct library finalization routine depending on
	whether the library has controlled objects or this is a VM compilation.
	(Gen_Finalize_Library_Ada): New routine. This procedure generates calls
	to library-level finalizers of compiled units in reverse order of
	elaboration. It also produces exception management code and reraises a

	(Gen_Finalize_Library_C): New routine. This procedure generates calls to
	library-level finalizers of compiled units in reverse order of
	elaboration.
	(Gen_Finalize_Library_Defs_C): New routine. This procedure generates the
	definitions of all library-level finalizers available to the compilation
	(Gen_Main_Ada): Directly call Adafinal which now contails all target
	dependent code.
	(Gen_Main_C): Add new local constant Needs_Library_Finalization. Call
	System.Standard_Library.Adafinal directly. If the library needs
	finalization actions, create the sequence of finalization calls.
	(Gen_Output_File_Ada): Alphabetize local variables and constants.
	Generate a with clause for System.Soft_Links when compiling for a VM.
	Remove the code which imports System.Standard_Library.Adafinal as
	Do_Finalize. Generate the library finalization routine.
	(Gen_Output_File_C): Add new local constant Needs_Library_Finalization.
	If the library needs finalization actions, create all the definitions
	of library- level finalizers.
	(Has_Finalizer): New routine. Determines whether at least one compiled
	unit has a library-level finalizer.
	Add type Qualification_Mode.
	(Set_Unit_Name): Add a formal which controls the replacement of a dot.
	* einfo.adb: New usage of field 15 as Return_Flag.

a9d8907c20 atree.ads, atree.adb: Add support for Elist24 field 
2005-03-08  Javier Miranda  <miranda@adacore.com>
	    Robert Dewar  <dewar@adacore.com>
	    Thomas Quinot  <quinot@adacore.com>

	Add support for Elist16 field
	Add support for Elist24 field

	* einfo.ads, einfo.adb (Abstract_Interfaces,
	Set_Abstract_Interfaces): New subprograms.
	(Abstract_Interface_Alias, Set_Abstract_Interface_Alias): New
	subprograms.
	(Access_Disp_Table, Set_Access_Disp_Table): Modified to handle a list of
	entities rather than a single node.
	(Is_Interface, Set_Is_Interface): New subprogram
	(First_Tag_Component): New syntesized attribute
	(Next_Tag_Component): New synthesized attribute
	(Write_Entity_Flags): Upgraded to write Is_Interface
	(Write_Field24_Name): Upgraded to write Abstract_Interfaces
	(Write_Field25_Name): Upgraded to write Abstract_Interface_Alias
	(Task_Body_Procedure): New subprogram to read this attribute.
	(Set_Task_Body_Procedure): New subprogram to set this attribute.
	(Has_Controlled_Component): Now applies to all entities.
	This is only a documentation change, since it always worked to apply
	this to other than composite types (yielding false), but now this is
	official.
	Update documentation on Must_Be_Byte_Aligned for new spec

	* tbuild.adb, exp_dist.adb, exp_disp.adb, exp_ch3.ads, exp_ch3.adb,
	exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
	uses of the Access_Disp_Table attribute to reference the first dispatch
	table associated with a tagged type. As
	part of the implementation of abstract interface types,
	Access_Disp_Table has been redefined to contain a list of dispatch
	tables (rather than a single dispatch table).
	Similarly, upgrade all the references to Tag_Component by the
	new attribute First_Tag_Component.
	(Find_Inherited_TSS): Moved to exp_tss.
	Clean up test in Expand_N_Object_Declaration for cases
	where we need to do a separate assignment of the initial value.
	(Expand_N_Object_Declaration): If the expression in the
	declaration of a tagged type is an aggregate, no need to generate an
	additional tag assignment.
	(Freeze_Type): Now a function that returns True if the N_Freeze_Entity
	is to be deleted.
	Bit packed array ops are only called if operands are known to be
	aligned.
	(Component_Equality): When returning an N_Raise_Program_Error statement,
	ensure that its Etype is set to Empty to avoid confusing GIGI (which
	expects that only expressions have a bona fide type).
	(Make_Tag_Ctrl_Assignment): Use Build_Actual_Subtype to correctly
	determine the amount of data to be copied.

	* par.adb (P_Interface_Type_Definition): New subprogram that parses the
	new syntax rule of Ada 2005 interfaces (for AI-251 and AI-345):
	    INTERFACE_TYPE_DEFINITION ::=
	      [limited | task | protected | synchronized] interface
	        [AND interface_list]

	* par-ch3.adb (P_Type_Declaration): Modified to give support to
	interfaces.

	record type definition and
	derived type definition nodes.
	(Synchronized_Present, Set_Synchronized_Present): New subprograms.
	(Task_Present, Set_Task_Present): New subprogram.
	(Task_Body_Procedure): Removed.
	(Set_Task_Body_Procedure): Removed.
	These subprogram have been removed because the attribute
	Task_Body_Procedure has been moved to the corresponding task type
	or task subtype entity to leave a field free to store the list
	of interfaces implemented by a task (for AI-345)
	Add Expression field to N_Raise_Statement node for Ada 2005 AI-361
	(Null_Exclusion_Present): Change to Flag11, to avoid conflict with
	expression flag Do_Range_Check
	(Exception_Junk): Change to Flag7 to accomodate above change
	(Box_Present, Default_Name, Specification, Set_Box_Present,
	Set_Default_Name, Set_Specification): Expand the expression
	"X in N_Formal_Subprogram_Declaration" into the corresponding
	two comparisons. Required to use the csinfo tool.

	* exp_ch11.adb (Expand_N_Raise_Statement): Deal with case where
	"with string" given.

        * sem_ch11.adb (Analyze_Raise_Statement): Handle case where string
        expression given.

	* par-ch11.adb (P_Raise_Statement): Recognize with string expression
	in 2005 mode

	* exp_ch9.adb (Build_Task_Proc_Specification): Modified to use entity
	attribute Task_Body_Procedure rather than the old semantic field that
	was available in the task_type_declaration node.

	* par-ch12.adb (P_Formal_Type_Definition): Modified to handle formal
	interface type definitions.
	(P_Formal_Derived_Type_Definition): Modified to handle the list of
	interfaces.

	* par-ch9.adb (P_Task): Modified to handle the list of interfaces in a
	task type declaration.
	(P_Protected): Modified to handle the list of interfaces in a
	protected type declaration.

	value by a warning message.
	(Resolve_Type_Conversion): If the mixed-mode expression is interpreted

	* stringt.ads, stringt.adb: Handle full UTF-32 range.
	Remove ["0A"] from comment, since it can look like a line terminator.
	Currently we don't permit this, but this is under discussion by the
	ARG, and it is easy enough to use a different example.

	* s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for

	wrong null-exclusion value by a warning message.
	(Enable_Range_Check): Do range check if the prefix is an
	explicit dereference whose designated object is an unconstrained array.
	Current algorithm for removing duplicate checks is over-eager in this
	case.

	* sem_ch5.adb (Analyze_Assignment): Replace the error messages on wrong
	null-exclusion value by a warning message

	describing the new layout.
	(Dispatch_Table): The expander computes the actual array size, allocates
	the Dispatch_Table record accordingly, and generates code that displaces
	the base of the record after the Typeinfo_Ptr component. The access to
	these components is done by means of local functions.
	(Offset_To_Top): New function.
	(Typeinfo_Ptr): New function.

	and result, and issuing an error if there is no controlling type for
	the formal subprogram.
	(Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
	which is an unclean use of that field, we set the new field
	Corresponding_Formal_Spec to make the formal subprogram available to
	processing in Analyze_Subprogram_Declaration.
	(Analyze_Formal_{Discrete, Decimal_Fixed_Point, Fixed_Point,
	Floating_Point, Modular_Integer, Signed_Integer}_Type: Make formal type
	Constrained, so that it is is does not statically match its anonymous
	base type.

	* sem_ch6.adb (Analyze_Subprogram_Specification): Include test for
	abstract formal subprograms in error check for functions returning
	abstract types. Set scope of new designator for
	a parameterless subprogram, so that it is available when checking the
	body for nested subprograms, before full analysis of said body.
	(Analyze_Subprogram_Body): Warn on inlining bodies with nested
	subprogram only if inner one comes from source.
	(Analyze_Function_Call): If the call is given in object notation, the
	analysis of the name rewrites the node and analyzes it with the proper
	argument list. After analyzing the name, if the call has been rewritten
	and the result type is set, no further analysis is needed.
	(Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
	mark in function specification, in a context where the formals are
	visible and hide outer homographs.

	* sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
	as the tagged type for the cases of abstract formal subprograms and
	renamings of those.  Clean up spec comments.

	that has statically tagged operands.
	(Check_Dispatching_Call): Check for the case of an actual given by
	a tag-indeterminate function call whose type is an ancestor of the
	containing call's associated tagged type. This situation can occur
	for inherited primitives with function defaults. In this case we
	use the tagged type's tag directly as the controlling argument for
	the calls.
	(Expand_Call): Name change on call to Expand_Dispatch_Call.

	* sprint.adb (Sprint_Node_Actual): Split
	N_Formal_Subprogram_Declaration into two alternatives for the new

	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,

	 __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

	* 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.

	(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.

	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.

	when in deleted code, because gigi needs properly ordered freeze
	actions to annotate types.

	* freeze.adb (Is_Fully_Defined): Predicate must be recursive, to
	prevent the premature freezing of record type that contains
	subcomponents with a private type that does not yet have a completion.
