Since these insns run in usermode, there should be no need to setup
RET[ENI] to safe values. They won't be dereferenced, and any insn
that returns via them are valid only in supervisor mode. Since this
is in the main exception code path, saving any insn at all is good
as it gets multiplied quickly (as in O(n^2) times).

The multi-arch patch made GDBserver do the the wrong siginfo layout
conversion, because most uses of `linux_is_elf64' were removed, and it
ended up never set. A global really is the wrong thing to use as
elf64-ness is a per-process property; `linux_is_elf64' was just
accidentally left behind.
Tested on x86_64 Fedora 17.

There's no need for every arch to pre-allocate disabled_regsets.
Chances are the array won't be used.
(I have a hunch that with some more work we could dispense with
initialize_regsets_info.)
Tested on x86_64 Fedora 17 w/ -lmcheck.

This fixes the regression reported at
<http://sourceware.org/ml/gdb-patches/2013-06/msg00185.html>.
GDBserver was reaching:
static int
regsets_fetch_inferior_registers (struct regsets_info *regsets_info,
struct regcache *regcache)
{
struct regset_info *regset;
int saw_general_regs = 0;
int pid;
struct iovec iov;
regset = regsets_info->regsets;
pid = lwpid_of (get_thread_lwp (current_inferior));
while (regset->size >= 0)
{
void *buf, *data;
int nt_type, res;
if (regset->size == 0
|| regsets_info->disabled_regsets[regset - regsets_info->regsets])
{
>>>>>>> regset ++; <<<<<<< HERE
continue;
}
Because info->disabled_regsets[] was not being initialized, and that
causes all sorts of wrong.

While enhancing the warning printed in when SuspendThread fails,
I accidently changed the format used to print the error code
from %u to %d. This patch reverts it back.
gdb/ChangeLog:
* windows-nat.c (thread_rec): Revert format used to print
error code returned by SuspendThread from %d back to %u.
The windows-nat.c debug traces print the thread ID in base 16,
but give no indication of it. So, in a trace like the following...
gdb: kernel event for pid=4816 tid=720 code=CREATE_THREAD_DEBUG_EVENT)
... where tid is "720", it's easy to be confused and think that
the thread ID is 720 rather than 0x720. This patch avoids the
confusion by adding the usual "0x" prefix used for hexadecimal
values.
gdb/ChangeLog:
* windows-nat.c (windows_continue): Add "0x" prefix for thread
ID in debug trace.
(get_windows_debug_event): Likewise, for all debug traces.
This patch adds the thread ID to a warning printed when a call to
SuspendThread fails. It will help investigate issues, particularly
when correlated with the various debug traces provided by the
windows-nat module.
For the record, the output has been changed from...
warning: SuspendThread failed. (winerr 6)
... to ...
warning: SuspendThread (tid=0x720) failed. (winerr 6)
gdb/ChangeLog:
* window-nat.c (thread_rec): Add thread ID in SuspendThread
warning message.
Fix incorrect usage of ELF32_R_SYM introduced in ifunc changes.

2013-06-11 Will Newton <will.newton@linaro.org>
* elf64-aarch64.c (elf_aarch64_get_local_sym_hash): Use

Since many people don't have a Blackfin toolchain available, only try to
regenerate the header file when in maintainer mode. This file rarely changes,
and when it does, we commit the generated output, so there's almost never a
need to run directly on an end system.
