	lexsup.c (parse_args): Check whether provided SONAME is empty
	string.  If yes, warn and ignore it.  Don't overwrite valid SONAME
	with empty string.
watchpoint-reuse-slot.exp: Correctly skip unsupported commands.

The test case "watchpoint-reuse-slot.exp" yields a lot of failures on
s390/s390x: all instances of awatch, rwatch, and hbreak are performed
even though they aren't supported on these targets.  This is because
the test case ignores non-support error messages when probing for
support of these commands, like:

    (gdb) rwatch buf.byte[0]
    Target does not support this type of hardware watchpoint.

The patch adds handling for this case in the appropriate
gdb_test_multiple invocations.

gdb/testsuite/
	* gdb.base/watchpoint-reuse-slot.exp: Handle the case that the
	target lacks support for awatch, rwatch, or hbreak.

This constifies the parameters to search_symbols and fixes up the
fallout.

Linker foreign output format support for PowerPC64 ELFv2

Makes the ld srec tests pass.  Uses a horrible scan through symbols to
find ELF fields for symbol definitions, but the generic linker doesn't
offer anything better.  Might be slow.  Anyway, sane people will link
to ELF output then objcopy to convert formats.

	* elf64-ppc.c (abiversion, set_abiversion): Move earlier.
	(ppc64_elf_branch_reloc): Adjust addend for ELFv2 local offset.
	(ppc64_elf_set_toc): Set ".TOC." symbol value when using
	generic linker.
	(ppc64_elf_relocate_section): Disable ELFv2 function entry
	optimisation when --traditional-format.
Don't include sys/param.h

sys/param.h on recent versions of powerpc glibc ends up including
asm/elf.h via asm/sigcontex.h.  asm/elf.h defines R_PPC_* and R_PPC64_*
macros, which clash with our include/elf/ppc.h and include/elf/ppc64.h.
It turns out that no current source uses LD_PATHMAX, so there is no
need for limits.h or sys/param.h, except for one occurrence of UINT_MAX.
I don't have a quarrel with limits.h, but it seems unnecessary just
for UINT_MAX.

	* sysdep.h: Don't include limits.h and sys/param.h.  Don't
	include unistd.h twice.
	(LD_PATHMAX): Don't define.
	* ldlang.c (lang_common): Don't use UINT_MAX.
Add symbols for global entry stub, and report stats

The undefined function symbols (with non-zero value) on global entry
stubs are discarded by objdump when disassembling, so give objdump
another symbol to mark the stubs.

Also fixes a couple of bugs:
- entry_section was set to .opd for ELFv2, which meant a hard error
  rather than a warning when _start wasn't defined.
- global entry stubs were not built if they were the only type of
  stub in an executable.

bfd/
	* elf64-ppc.c (ppc_stub_type): Add ppc_stub_global_entry.
	(struct ppc_link_hash_table): Increase size of stub_count array.
	(build_global_entry_stubs): Emit symbol on global entry stub.
	(ppc64_elf_build_stubs): NULL check htab->brlt.  Add global entry
	stub stats.
ld/
	* emultempl/ppc64elf.em (stub_added): Delete.
	(gld${EMULATION_NAME}_finish): Call ppc64_elf_build_stubs even when
	none of the usual stubs have been added.  Only change entry_section
	for ELFv1.
Reorganise struct bfd

for better packing.  Removes a field and a flag that are never set.

bfd/
	* bfd.c (struct bfd): Reorganise for better packing.  Delete

	* coff-tic4x.c: Remove HAS_LOAD_PAGE from extra flags in target vecs.
binutils/

use cmd_sfunc_ftype and cmd_cfunc_ftype more

This patch changes a few more spots to use either cmd_sfunc_ftype or
cmd_cfunc_ftype, as appropriate.  This is a bit cleaner.

Tested by rebuilding.

Handle volatile array types in dwarf2read.c.

read_tag_const_type propagates the cv-qualifier to the array element type,
but read_tag_volatile_type didn't. Make sure that both cv-qualifiers that
apply to array types are handled the same.

gdb/ChangeLog

	* dwarf2read.c (add_array_cv_type): New function.
	(read_tag_const_type): Call add_array_cv_type for TYPE_CODE_ARRAY.

	vulture, vilify, villar): New volatile array constants.
	(vindictive, vegetation): New const volatile array constants.
	* gdb.base/volatile.exp: Test volatile and const volatile array
	types.

Set DF_STATIC_TLS for PIEs

Remove unused Linux libthread_db callbacks

gdb/proc-service.c includes several libthread_db callbacks that do not
exist in gdb/gdbserver/proc-service.c.  Other than in proc_service.h,
there is no reference to any of these callbacks in any revision of
nptl_db or linuxthreads_db in glibc's git repo so it seems likely that
these functions have never been called.  This commit removes them.

Taking an undefined function's address in an executable

doesn't always mean you need to define a function symbol on plt code.
If all references are in read-write sections, then using dynamic relocs
is OK.

bfd/
	* elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Clear
	pointer_equality_needed when !readonly_dynrelocs.

	* ld-powerpc/ambiguousv2b.d: New.
	* ld-powerpc/powerpc.exp: Run new tests.
This testcase currently does not handle powerpc branches. It kinda
does in a way, because the arm/aarch64 branch instruction is the
same as powerpc's, but the target triplet pattern is not there.

In summary, the testcase fails to locate the branch offset and causes
a failure and the early termination of the test.

The following patch adds a separate conditional block for powerpc (to keep
things organized), allowing the testcase to continue.

2014-07-02  Luis Machado  <lgustavo@codesourcery.com>

	* gdb.trace/entry-values.exp: Handle powerpc-specific branch
	instruction.
