37a6ac445d Run ar with --plugin for LTO 11 test
Objects built with -fno-fat-lto-objects (the default for gcc-4.9) have
no normal symbols, except things like __gnu_lto_slim.  These useless
symbols are the ones put into the archive index, and of course nothing
references them so no objects are extracted by the linker.  Running
ar with --plugin changes ar behaviour to put the lto symbols into the
archive index.

	PR 17112
	* ld-plugin/lto.exp: When building liblti-11.a, pass
	--plugin path_to_gcc/liblto_plugin.so to ar.

b2ee242b93 PR gdb/17096: async support breaks remote debugging on Windows
On Windows, with "maint set target-async on" (the default since
a09dd441), Ctrl-C fails to stop a remote target.

With maint target-async on, the SIGINT signal handler doesn't send the
remote interrupt request immediately.  Instead, it marks an async
handler as ready, and then the main event loop wakes up and notices
that the SIGINT async signal handler token was set, and calls the
corresponding event handler, which sends the remote interrupt request.

On POSIX-like systems, the SIGINT signal makes the select/poll in the
main event loop wake up / return with EINTR.  However, on Windows,
signal handlers run on a separate thread, and Windows doesn't really
have a concept of EINTR.  So, just marking the async handler
(effectively just setting a flag) does not wake up gdb_select.
Instead, we need to call gdb_call_async_signal_handler from the signal
handler.  The Windows version (in mingw-hdep.c) sets a Windows event
that gdb_select's WaitForMultipleObjects is waiting for.

Confirmed that with this, Ctrl-C interrupts the remote target on
Windows.  Also regression tested on x86_64 Fedora 20 against
GDBserver.

f0f9ff9530 convert to_get_thread_local_address to use target delegation
This converts to_get_thread_local_address to use
TARGET_DEFAULT_NORETURN.  One possible oddity is that this changes the
text of the kind of exception thrown in some cases.  This doesn't seem
to be a problem; in fact perhaps the final call to 'error' in
target_translate_tls_address should be changed to call
generic_tls_error.

f1d7f4a64c Ensure ld testsuite gcc -B options precede $CC -B options
Various ld-elf/shared.exp and ld-plugin/lto.exp tests simply appended
the testsuite -B options intended to force gcc use the linker under test.
This fails if $CC itself has -B options, as when setting CC to run gcc
out of a build directory.  Net result is that tests were run using
the gcc build dir collect-ld.

2b239efbec 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.

7341d5e22f 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.

2dc0e7b400 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.

aebf9d247e 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.

b67a2c6fd4 Associate dummy_frame with ptid
This patch is to add ptid into dummy_frame and extend frame_id to
dummy_frame_id (which has a ptid field).  With this change, GDB uses
dummy_frame_id (thread ptid and frame_id) to find the dummy frames.

Currently, dummy frames are looked up by frame_id, which isn't
accurate in non-stop or multi-process mode.  The test case
gdb.multi/dummy-frame-restore.exp shows the problem and this patch can
fix it.

Test dummy-frame-restore.exp makes two inferiors stop at
different functions, say, inferior 1 stops at f1 while inferior 2
stops at f2.  Set a breakpoint to a function, do the inferior call
in two inferiors, and GDB has two dummy frames of the same frame_id.
When the inferior call is finished, GDB will look up a dummy frame
from its stack/list and restore the inferior's regcache.  Two
inferiors are finished in different orders, the inferiors' states are
restored differently, which is wrong.  Running dummy-frame-restore.exp
under un-patched GDB, we'll get two fails:

FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 2
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 1

With this patch applied, GDB will choose the correct dummy_frame to
restore for a given inferior, because ptid is considered when looking up
dummy frames.  Two fails above are fixed.

Regression tested on x86_64-linux, both native and gdbserver.
