The profile of command completers has been change to returna VEC
of char_ptr. Most completers were updated, except the one in
remote-sim.c.
Unfortunately, to make things a little more difficult, the meat of
the completer is actually implemented in the sim, were VECs are not
available. This patch thus translates the returned array into a VEC,
and then returns that VEC.

This patch sets the windows target to use their own version of
the iterate_over_objfiles_in_search_order gdbarch method, in
order to make global symbol searches sensitive to the current
objfile.
gdb/ChangeLog:
* windows-tdep.h (windows_iterate_over_objfiles_in_search_order):
Add declaration.
* windows-tdep.c: #include "objfiles.h".

* i386-cygwin-tdep.c (i386_cygwin_init_abi): Likewise.
This patch introduces the "iterate_over_objfiles_in_search_order"
gdbarch method, as well as its default implementation, and converts
the areas where it will matter to using this gdbarch method.
The default method implementation is the only one installed, and
the changes should have no functional impact in terms of behavior.
This only paves the way for the architectures that will need their
own version.
gdb/ChangeLog:
* gdbarch.sh: Add generation of
"iterate_over_objfiles_in_search_order_cb_ftype" typedef in

(default_read_var_value) [case LOC_UNRESOLVED]: Resolve the

The search order used in this patch breaks global symbol lookups
for certain symbols when copy-relocation is used. A slightly different
search order will be implemented later.
gdb/ChangeLog:
Revert the following patch:
* findvar.c (default_read_var_value): For LOC_UNRESOLVED symbols,
try locating the symbol in the symbol's own objfile first, before
extending the search to all objfiles.
* symtab.c (lookup_symbol_aux_objfile): New function, extracted
out of lookup_symbol_aux_symtabs.

(lookup_static_symbol_aux): Update call to lookup_symbol_aux_symtabs.
(lookup_symbol_global): Search for matches in the block's objfile

With an Ada program, trying to break on a specific Ada task, but
with the wrong capitalization of the `task' keyword, we currently
get only pieces of the "garbage" that caused the error:
(gdb) b *rendez_vous'address TASK 2
Garbage 2 at end of command
Pushing this a little further:
(gdb) b *rendez_vous'address TASK Task TaSK 2
Garbage 2 at end of command
Another interesting failure mode:
(gdb) b *rendez_vous'address TASK if
Argument required (expression to compute).
The parser skipped `TASK', then found the `if' keyword, and thus
started looking for a condition.
This patch fixes the problem by aborting the parsing as soon as
an invalid keyword is found. This makes it consistent with the
case where the REST parameter is passed as NULL (where an error
is raised immediately after seeing the first invalid keyword).
It also introduces a new testcase that reproduces all above scenarios.

* breakpoint.c (find_condition_and_thread): Stop parsing
as soon as the first invalid keyword is found.

The code for handling calls to internal functions (esp., Python
functions) and for handling STT_GNU_IFUNC had not been added to the Ada
expression evaluator. This change adapts them from eval.c.
gdb/Changelog:
* ada-lang.c (ada_evaluate_subexp): Add cases for
TYPE_CODE_INTERNAL_FUNCTION and for TYPE_GNU_IFUNC, following
their treatment in eval.c.
SPARC-T4 adds a "compare and branch" instruction which fuses
a compare and a branch instruction into one. The branch
is non-delayed, there are no anulling facilities, and the
displacement is 10-bits.
This also corrects the existing bit test for Branch on
Integer Register. The distinguising characteristic between
Branch on Integer Register and Compare-and-Branch is bit
28. The existing code was checking bit 24 for zero, but
that's pointless because bit 24 is already covered by
the "X_OP2 (insn) == 3" test.

The problem showed up on AIX when we switched from the system linker
to GNU ld. What happens is that configure is adding -lpthdebug to
CONFIG_LDFLAGS when AIX thread debugging support is detected. But
this causes the "-lpthread" switch to be placed at the _before_
GDB's .o files (see Makefile.in):
INTERNAL_LDFLAGS = [...] $(CONFIG_LDFLAGS)
[...]
gdb$(EXEEXT): gdb.o $(LIBGDB_OBS) $(ADD_DEPS) $(CDEPS) $(TDEPLIBS)
rm -f gdb$(EXEEXT)
$(CC_LD) $(INTERNAL_LDFLAGS) $(WIN32LDAPP) \
-o gdb$(EXEEXT) gdb.o $(LIBGDB_OBS) \
$(TDEPLIBS) $(TUI_LIBRARY) $(CLIBS) $(LOADLIBES)
And as a result of this, the linker reports an error due to some
symbols in aix-thread.o not being satisfied.
This patch adds the "-lpthread" switch to LIBS instead, which should
be the right place to add it.

This patch fixes the following problem:
% gdb foo
(gdb) b main
/[...]/progspace.c:216: internal-error: set_current_program_space: Assertion `pspace != NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
The problem happens when we try to get the program space from
a minimal symbol. For that, we go through the minimal symbol's
obj_section->objfile->pspace. But the minimal symbol's obj_section
is not set, and thus we somehow get a NULL program space. And
the reason why the obj_section is not set is because the XCOFF
reader did not pass the bfd_section when calling minsyms.c's
prim_record_minimal_symbol_and_info.
gdb/ChangeLog:
* xcoffread.c (xcoff_secnum_to_sections): New function.
