1cff9a8964 Use the kernel's sa_restorer for aarch64.
gdb was happy with what we had, but libgcc and libunwind weren't.
libgcc is happy with the kernel's restorer (because of the extra nop),
though libunwind looks like it's going to need code changes regardless.

We could make our restorer more like the kernel's one, but why bother
when we can just let the kernel supply the canonical one?

36f451a6d9 Fix signal trampolines.
* LP32 should use sa_restorer too. gdb expects this, and future (>= 3.15) x86
  kernels will apparently stop supporting the case where SA_RESTORER isn't
  set.

* gdb and libunwind care about the exact instruction sequences, so we need to
  modify the code slightly in a few cases to match what they're looking for.

* gdb also cares about the exact function names (for some architectures),
  so we need to use __restore and __restore_rt rather than __sigreturn and
  __rt_sigreturn.

* It's possible that we don't have a VDSO; dl_iterate_phdr shouldn't assume
  that getauxval(AT_SYSINFO_EHDR) will return a non-null pointer.

This fixes unwinding through a signal handler in gdb for all architectures.
It doesn't fix libunwind for arm and arm64. I'll keep investigating that...

26a8eb50a8 POSIX says <signal.h> gets you ucontext_t.
POSIX also says that ucontext_t's uc_sigmask has type sigset_t.

MIPS64 strace needs this.

The #define is to keep chromium off our lawn; otherwise it tries to redefine
all this stuff itself. We should probably clean that up and remove the #define.

Dmitriy Ivanov
9aea164457 Add IFUNC support for arm64 and IRELATIVE reloc
There are number of changes in the way IFUNC related relocations are done:
 1. IRELATIVE relocations are now supported for x86/x86_64 and arm64.
 2. IFUNC relocations are now relying on static linker to generate
    them in correct order - this removes necessety of additional
    relocation pass for ifuncs.
 3. Related to 2: rela?.dyn relocations are preformed before .plt ones.
 4. Ifunc are resolved on symbol lookup this approach allowed to avoid
    mprotect(PROT_WRITE) call on r-x program segments.

a4831cb4a3 Add pthread_gettid_np and re-expose __get_thread for LP32.
A lot of third-party code calls the private __get_thread symbol,
often as part of a backport of bionic's pthread_rwlock implementation.
Hopefully this will go away for LP64 (since you're guaranteed the
real implementation there), but there are still APIs that take a tid
and no way to convert between a pthread_t and a tid. pthread_gettid_np
is a public API for that. To aid the transition, make __get_thread
available again for LP32.

011e111d29 Ensure __set_errno is still visible on LP32.
The use of the .hidden directive to avoid going via the PLT for
__set_errno had the side-effect of actually making __set_errno
hidden (which is odd because assembler directives don't usually
affect symbols defined in a different file --- you can't even
create a weak reference to a symbol that's defined in a different
file).

This change switches the system call stubs over to a new always-hidden
__set_errno_internal and has a visible __set_errno on LP32 just for
binary compatibility with old NDK apps.

9685c30a23 Upgrade bionic to tzdata2014g.
From the release notes:

  Changes affecting future time stamps

    Turks & Caicos is switching from US eastern time to UTC-4 year-round,
    modeled as a switch from EST/EDT to AST on 2014-11-02 at 02:00.

  Changes affecting past time stamps

    Time in Russia or the USSR before 1926 or so has been corrected by
    a few seconds in the following zones: Asia/Irkutsk,
    Asia/Krasnoyarsk, Asia/Omsk, Asia/Samarkand, Asia/Tbilisi,
    Asia/Vladivostok, Asia/Yakutsk, Europe/Riga, Europe/Samara.  For
    Asia/Yekaterinburg the correction is a few minutes.  (Thanks to
    Vladimir Karpinsky.)

    The Portuguese decree of 1911-05-26 took effect on 1912-01-01.
    This affects 1911 time stamps in Africa/Bissau, Africa/Luanda,
    Atlantic/Azores, and Atlantic/Madeira.  Also, Lisbon's pre-1912
    GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32.
    (Thanks to Stephen Colebourne for pointing to the decree.)

    Asia/Dhaka ended DST on 2009-12-31 at 24:00, not 23:59.

    A new file 'backzone' contains data which may appeal to
    connoisseurs of old time stamps, although it is out of scope for
    the tz database, is often poorly sourced, and contains some data
    that is known to be incorrect.  The new file is not recommended
    for ordinary use and its entries are not installed by default.
    (Thanks to Lester Caine for the high-quality Jersey, Guernsey, and
    Isle of Man entries.)

    Some more zones have been turned into links, when they differed
    from existing zones only for older time stamps.  As usual,
    these changes affect UTC offsets in pre-1970 time stamps only.
    Their old contents have been moved to the 'backzone' file.
    The affected zones are: Africa/Bangui, Africa/Brazzaville,
    Africa/Douala, Africa/Kinshasa, Africa/Libreville, Africa/Luanda,
    Africa/Malabo, Africa/Niamey, and Africa/Porto-Novo.
