prefix is not a scalar type, place error message on prefix, not on
type entity.
From-SVN: r91894

to be resolved later as part of Analyze_Iteration_Scheme's call to
Make_Index.
From-SVN: r91893
* sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
used to record an implicit dereference as a read operation on its
prefix when operating under -gnatc. Necessary to avoid spurious
'variable assigned but never read' warnings in that mode.
(Process_Indexed_Component, Analyze_Selected_Component): When the prefix
is a non-overloaded implicit dereference, call the above subprogram to
ensure proper recording of references.
From-SVN: r91892
* nlists.adb (Prepend_Debug): Remove parameters and nest within
Prepend.

Specific_Build_Stub_Target): New subprograms.
(Build_Subprogram_Calling_Stubs): Make this procedure independent from
the PCS implementation used, using the above PCS-customized subprograms.
Minor reformatting.

implementation of the partition communication subsystem in ancillary

PolyORB_Support.Build_Stub_Type): New subrograms containing the
PCS-specific part of Add_Stub_Type.

E.4(19) check.
* rtsfind.ads: New entity System.PolyORB_Interface.Make_Ref

This deals with the case where the pragma Import specified
an external name, to be handled by the back end.
* sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
subprogram which is Imported with convention Intrinsic if an
External_Name argument is specified.
(Process_Import_Or_Interface): Properly diagnose link name argument.
(Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion
with Sem_Ch6.Cannot_Inline.
(Process_Inline): Provide separate warning for inapplicable inline
pragma.
(Cannot_Inline): Reject subprograms that have an at_end handler, so that
treatment is uniform on different targets.
From-SVN: r91882
* exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
with an implicit dereference as its prefix, use
Insert_Explicit_Dereference instead of merely rewriting the prefix into
an explicit dereference. This ensures that a reference to the original
prefix is generated, if appropriate.
* sem_util.adb (Insert_Explicit_Dereference): When an implicit
dereference is rewritten to an explicit one, generate a reference to
the entity denoted by its prefix using the original prefix node, so
the dereference can be properly recorded as a read of the denoted
access value, if appropriate.
* sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
emitting 'assigned but never read' warning on a variable on the basis
that it has an access type.
(Check_References): Emit unreferenced warning when the scope is a
subprogram body.
From-SVN: r91881
* decl.c (maybe_pad_type): Use TYPE_SIZE_UNIT of the input type for
TYPE_SIZE_UNIT of result type if SIZE is not specified.
(make_aligning_type): Pass -1 as ADDRESSABLE to prevent the creation
of a bitfield, which we know is useless and causes trouble because of
alignment implications.
* utils.c (create_var_decl): Set DECL_COMMON again on targets without
BSS sections.
(process_attributes): Clear DECL_COMMON again when a section attribute
is present.
(finish_record_type): Independently track if RECORD_TYPE has SIZE and/or
SIZE_UNIT already set and use to compute final SIZE and SIZE_UNIT.
(create_field_decl): Special case ADDRESSABLE negative to mean
"no bitfield creation", to be used by make_aligning_type. Don't
restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
fields claimed addressable still have to be bitfields. Use
value_factor_p instead of a raw binop construction to check for the
position's alignment.
