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

DB is found in the ali file. Any unit compiled with pragma
Detect_Blocking active forces its effect in the whole partition.

Detect_Blocking is active and delay is called from a protected

* 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

* 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.
