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.

	associated comment on field usage.
	* a-tags.adb (Get_RC_Offset): Removed.
	(Needs_Finalization): New routine.

	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.

	targets. Set the correct library finalization routine depending on
	whether the library has controlled objects or this is a VM compilation.

	to library-level finalizers of compiled units in reverse order of
	elaboration. It also produces exception management code and reraises a

	library-level finalizers of compiled units in reverse order of
	elaboration.

	definitions of all library-level finalizers available to the compilation
	(Gen_Main_Ada): Directly call Adafinal which now contails all target
	dependent code.

	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.
