Minor reformatting.
Add Unreferenced and Warnings (Off) pragmas for cases of
variables modified calls where they are IN OUT or OUT parameters and
the resulting values are not subsequently referenced. In a few cases,
we also remove redundant code found by the new warnings.

* adaint.c, socket.c, cal.c: Initial port to arm-mentor-nucleus.
* expect.c: Initial port to arm-mentor-nucleus.
Use kill for __gnat_kill() on VMS.
2007-10-15 Emmanuel Briot <briot@adacore.com>
* ali.ads, ali.adb (Scan_ALI): Initialize XE.Tref to a known default
value.
(Xref_Record): Change type for Line, since in the case of a reference to
a predefined entity (as happens for array index types), the line is set
to 0.
Add support for parsing multiple array index types info, or
multiple inherited interfaces info. This information cannot be stored
in Xref_Entity_Record, which only supports a single instance of Tref_*,
and is therefore stored in the list of references instead. It has a
special treatement later on in tools that use this information.
2007-10-15 Tristan Gingold <gingold@adacore.com>
* debug.adb: Document use of -gnatd.a and -gnatd.I
* layout.adb: On OpenVMS -gnatd.a disables alignment optimization.
2007-10-15 Javier Miranda <miranda@adacore.com>
* exp_attr.adb (Expand_N_Attribute_Reference): Case Access,
Unchecked_Access, and Unrestricted_Access. Cleanup code that takes
care of access to class-wide interface types plus removal of bizarre
conversion of tagged object to access type (reported by Gary
Dismukes). After this patch there is no need to perform any
additional management on these nodes in Expand_Interface_Actuals.
* exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
that handles use of 'Access and 'Unchecked_Access applied to
actuals covering interface types. Such code is now
centralized in Expand_N_Attribute_Reference.
2007-10-15 Ed Schonberg <schonberg@adacore.com>
* exp_ch3.adb (Build_Init_Procedure): Keep separate the initialization
of tagged types whose ultimate ancestor is a CPP type.
(Freeze_Array_Type): For a packed array type, generate an initialization
procedure if the type is public, to handle properly a client that
specifies Normalize_Scalars.
2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
* exp_ch9.adb (Actual_Index_Expression): When the expansion occurs
inside a generic body, retrieve the full view of the entry family
discrete subtype if available.

* exp_dist.adb (Add_RACW_Primitive_Declarations_And_Bodies): Do not
attempt to generate stubs for hidden primitive operations.
2007-10-15 Vincent Celier <celier@adacore.com>
* mlib-tgt-specific.adb (Support_For_Libraries): New function,
returning None, used when there is no platform specific body for
MLib.Tgt.Specific.
2007-10-15 Bob Duff <duff@adacore.com>
* sem_case.adb, sem_ch13.adb, lib-sort.adb: Replace use of Heap_Sort_A
(passing'Unrestricted_Access of nested subprograms to Sort) with use of
the generic Heap_Sort_G, in order to avoid trampolines.
2007-10-15 Vasiliy Fofanov <fofanov@adacore.com>
Jose Ruiz <ruiz@adacore.com>
* vx_stack_info.c: New file.
* i-forbla-unimplemented.ads: New file.
* Makefile.in: i-forbla-unimplemented.ads: a variant of i-forbla.ads
for unsupported configurations; use it on VMS targets instead of the
real one.
(EXTRA_LIBGNAT_SRCS,EXTRA_LIBGNAT_OBJS for VxWorks): Include
vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
used by VxWorks targets to have access to task-specific data and be
able to extract the stack boundaries for stack checking.
Use system-vms-ia64.ads on ivms.
* Make-lang.in: Update dependencies.
* sysdep.c (__gnat_get_stack_info): Move to a standalone file
(vx_stack_info.c).
2007-10-15 Vincent Celier <celier@adacore.com>
* snames.adb, snames.ads: Add new standard name runtime_library_dir
* prj.ads (Language_Config): Add new component Runtime_Library_Dir

the source is unknown.

95 reserved word in its name.

Runtime_Library_Dir.

config project against the user project names.

not include a dot are always case insensitive.

detected.
* prj-util.adb (Value_Of (In_Array)): When Force_Lower_Case_Index is

* rtsfind.adb: (Load_RTU): Turn off style checks for Load call
2007-10-15 Gary Dismukes <dismukes@adacore.com>
* sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
association for an access component, add an association with null as
the expression. Remove testing for array subtypes and the setting in
that case of Ctyp to the array component type, which prevented proper
inclusion of an association for null-initialized arrays. Collapse
condition that tests for array subtypes into just a test of
Is_Partially_Initialized_Type (which already covers arrays anyway).
2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
* sem_ch12.adb: Minor code reformatting.
(Check_Generic_Child_Unit): Iterate over the homonym chain in order to

on the parent subtype and any new set of discriminants.
2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
* sem_ch4.adb: Minor code and comment reformatting.
(Analyze_Allocator): When the designated type of an unconstrained
allocator is a record with unknown discriminants or an array with
unknown range bounds, emit a detailed error message depending on the
compilation mode and whether the designated type is limited.
2007-10-15 Tristan Gingold <gingold@adacore.com>
* system-vms-ia64.ads: New file.
* system-vms_64.ads: Minor comment fix.
2007-10-15 Ed Schonberg <schonberg@adacore.com>
* sem_ch6.adb (Find_Corresponding_Spec): If the previous entity is a
body generated for a function with a controlling result that is a null
extension, discard the generated body in favor of the current explicit
one.
2007-10-15 Ed Schonberg <schonberg@adacore.com>
* sem_disp.adb (Find_Controlling_Arg): Examine the call node before
examining its original form, to handle properly operator calls that
have been rewritten.
2007-10-15 Olivier Hainque <hainque@adacore.com>

type, for dispatching calls.
