the request subreg is entirely contained in the requested component.
(simplify_gen_subreg): Return null for CONCATs that are rejected
by simplify_subreg.

* varasm.c (pending_assemble_externals): New static.
(assemble_external_real): Meat of assemble_external split out
to this new function.
(process_pending_assemble_externals): New function.
(assemble_external): Use gcc_assert. If flag_unit_at_a_time
is true and the basic test passes, merely cons the decl onto
the pending list to be handled later.
* tree.h: Declare process_pending_assemble_externals.
* cgraphunit.c (cgraph_optimize): Call it.
* config/h8300/h8300.h: Do not define ASM_OUTPUT_EXTERNAL.
From-SVN: r91914
* g-socket.ads (Get_Host_By_Address, Get_Host_By_Name): Clarify
documentation of the behaviour of these functions when passed an IP
address that has no record in the system hosts database and no reverse
record in the DNS.
* cstand.adb, a-tags.ads: Fix typos in comment.

Add some ??? comments asking for more comments
* s-poosiz.adb: Minor reformatting
Add comments on alignment requirement
* sinfo.ads: Remove obsolete comment and fix typo.
* gnat_ugn.texi: Update the section "The GNAT Driver and Project
Files" with the new tool and package names.
Reformatting to suppress most of the warnings for line too long
Document the new section "Project Search Path:" in the output of
gnatls -v.
Add gnatmetric section
* vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
-gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
and -eit to -ept. Added qualifier
/ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.

* sem_ch8.adb (Find_Type): If node is a reference to 'Base and the
prefix is not a scalar type, place error message on prefix, not on
type entity.
From-SVN: r91894
* sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
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.
(Remove_Next_Debug): Same fix
* nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
maintain back pointers now, though we did not used to, and comments
were out of date).
(Prepend): Remove pragma Inline.
(Remove_Next): Same cleanup
From-SVN: r91891
* lib-xref.adb (Generate_Reference): Handle properly a reference to an
entry formal, when an accept statement has a pragma Unreferenced for it.
* sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
and the Has_Pragma_Unreferenced flag for each formal before analyzing
the body, to ensure that warnings are properly emitted for each accept
statement of a given task entry.
From-SVN: r91888
* gnatmem.adb, gnatname.adb, gnatsym.adb, gprcmd.adb, vms_conv.adb:
Output the copyright message on a separate line from the version
message.
From-SVN: r91885
* exp_dist.adb (Specific_Build_General_Calling_Stubs,
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.
(PolyORB_Support.Helpers): New subunit containing supporting subprograms
for generation of DSA code targeted to the PolyORB PCS.
(Add_Stub_Type): Rewrite to isolate the parts that are specific to one
implementation of the partition communication subsystem in ancillary
subprograms.
(Specific_Build_Stub_Type, GARLIC_Support.Build_Stub_Type,
PolyORB_Support.Build_Stub_Type): New subrograms containing the
PCS-specific part of Add_Stub_Type.
(Insert_Partition_Check): Use runtime library function to perform
E.4(19) check.
* rtsfind.ads: New entity System.PolyORB_Interface.Make_Ref
(RE_Same_Partition): New entity, from s-parint.
* s-parint.ads, s-parint.adb (Same_Partition): New subprogram.
From-SVN: r91884
* exp_ch7.adb (Expand_Cleanup_Actions): If statement sequence of
construct is rewritten, preserve end label to permit source navigation.
From-SVN: r91883
* exp_ch6.adb (Expand_Call): Add comment on handling of back end
intrinsic
* exp_intr.adb (Expand_Intrinsic_Call): Ignore unrecognized intrinsic,
leaving call unchanged.
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.
