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.

This fixes a regression that Jan pointed out.
The bug is that some names were allocated by dwarf2read on the objfile
obstack, but then passed to SYMBOL_SET_NAMES with copy_name=0. This
violates the invariant that the names must have a lifetime tied to the
lifetime of the BFD.
The fix is to allocate names on the per-BFD obstack.
I looked at all callers, direct or indirect, of SYMBOL_SET_NAMES that
pass copy_name=0. Note that only the ELF and DWARF readers do this;
other symbol readers were never updated (and perhaps cannot be,
depending on the details of the formats). This is why the patch is
relatively small.
Built and regtested on x86-64 Fedora 20.

In arm-tdep.c, arm_skip_stub is installed to gdbarch
skip_trampoline_code, but in arm-linux-tdep.c,
find_solib_trampoline_target is installed to skip_trampoline_code.
That means gdb configured for arm-linux target doesn't recognize some
arm specific trampolines or stubs. Beside handling generic solib
trampoline, gdb for arm-linux target should be able to handle arm
specific trampolines. This patch is to skip arm specific stubs, if
any, and as a fallback, skip the generic solib trampoline.

In target arm-none-eabi, prologue unwinder is used for trampoline
'bx reg'. However, in target arm-linux, exidx unwinder is selected for
trampoline at first, which is not expected. The main function and the
trampoline is,
0x00009dfc <main+0>: push {r4, r5, r6, r7, lr}
......
0x0000ac30 <main+3636>: ldrdeq r3, [r1], -r8
0x0000ac34: bx r2
0x0000ac36: bx r4
and .ARM.exidx is:
0x9dfc <main>: @0xb404
Compact model index: 1
0x97 vsp = r7
0x20 vsp = vsp + 132
0x3f vsp = vsp + 256
0x80 0xf0 pop {r8, r9, r10, r11}
0xab pop {r4, r5, r6, r7, r14}
0xac38 <__aeabi_drsub>: 0x1 [cantunwind]
Trampolines 'bx r2' and 'bx r4' doesn't belong to main, but the exidx
for main is still selected form them because there is no end address
of each exidx entry.
Instead of teaching exidx unwinder ignore this trampoline (which looks
complicated and error prone), I decide to let stub unwinder to handle
trampoline, because stub undwinder is installed before exidx unwinder,
and this trampoline can be regarded as a stub too.
This patch is to add the code to match 'bx reg' trampoline in the
sniffer of stub unwinder.

In the example above the debug registers are being switched from this
state:
CONTROL (DR7): 0000000000050101 STATUS (DR6): 0000000000000000
DR0: addr=0x0000000000601040, ref.count=1 DR1: addr=0x0000000000000000, ref.count=0
DR2: addr=0x0000000000000000, ref.count=0 DR3: addr=0x0000000000000000, ref.count=0
to this:
CONTROL (DR7): 0000000000010101 STATUS (DR6): 0000000000000000
DR0: addr=0x0000000000601041, ref.count=1 DR1: addr=0x0000000000000000, ref.count=0
DR2: addr=0x0000000000000000, ref.count=0 DR3: addr=0x0000000000000000, ref.count=0
That is, before, DR7 was setup for watching a 2 byte region starting
at what's in DR0 (0x601040).
And after, DR7 is setup for watching a 1 byte region starting at
what's in DR0 (0x601041).
We always write DR0..DR3 before DR7, because if we enable a slot's
bits in DR7, you need to have already written the corresponding
DR0..DR3 registers -- the kernel rejects the DR7 write with EINVAL
otherwise.
The error shown above is the opposite scenario. When we try to write
0x601041 to DR0, DR7's bits still indicate intent of watching a 2-byte
region. That DR0/DR7 combination is invalid, because 0x601041 is
unaligned. To watch two bytes, we'd have to use two slots. So the
kernel errors out with EINVAL.
Fix this by always first clearing DR7, then writing DR0..DR3, and then
setting DR7's bits.
A little optimization -- if we're disabling the last watchpoint, then
we can clear DR7 just once. The changes to nat/i386-dregs.c make that
easier to detect, and as bonus, they make it a little easier to make
sense of DR7 in the debug logs, as we no longer need to remember we're
seeing stale bits.
Tested on x86_64 Fedora 20, native and GDBserver.
This adds an exhaustive test that switches between many different
combinations of watchpoint types and addresses and widths.

The recent libiberty patch caused issues when cross building
gdbserver. The Makefile ends invoking the build machine's "ar"
instead of the --host version:
ar ./libiberty.a \
./regex.o (...)
ar: illegal option -- .
Usage: ar [emulation options] [-]{dmpqrstx}[abcfilNoPsSuvV] [member-name] [count] archive-file file...
ar -M [<mri-script]
The libiberty configure script does probe for and finds an appropriate
AR. However, gdbserver's configure does not probe for AR and
overrides the AR used in the libiberty build by explicitly passing AR
to the sub-builds.
