arithmetic.
* exp_ch4.adb (Expand_Allocator_Expression): When compiling for
.NET/JVM targets, attach the newly allocated object to the access
type's finalization collection. Do not generate a call to
Set_Finalize_Address_Ptr on .NET/JVM because this routine does not
exist in the runtime.
(Expand_N_Allocator): When compiling for .NET/JVM targets, do not
create a custom Allocate for object that do not require initialization.

collection on .NET/JVM.
* exp_ch5.adb (Make_Tag_Ctrl_Assignment): Add special processing for
assignment of controlled types on .NET/JVM. The two hidden pointers
Prev and Next and stored and later restored after the assignment takes
place.
* exp_ch6.adb (Expand_Call): Add local constant Curr_S. Add specialized

Heap_Management and change the call to Finalize into Deep_Finalize.

(Make_Attach_Call): New routine.
(Make_Detach_Call): New routine.
(Process_Object_Declarations): Suppress the generation of

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):

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.

presence of a VM target, the routine generates calls to the proper
library finalization routine.
(Gen_Adainit_Ada): Import Finalize_Library_Objects only on non-VM
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
potential exception after all units have been finalized.
(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.

Generate a with clause for System.Soft_Links when compiling for a VM.

An aggregate project and its aggregated trees need to share the common
data structures used for lists of strings, packages,... This makes the
code simpler since otherwise we have to pass the root tree (also used
for the configuration file data) in addition to the current project
tree. This also avoids ambiguities as to which tree should be used.
And finally this saves a bit of memory.
(For_Every_Project_Imported): new parameter Tree.
Since aggregated projects are using a different tree, we need to let
the caller know which tree to use to manipulate the returned project.
