2013-02-18C++11 thread_local destructors supportSiddhesh Poyarekar
This feature is specifically for the C++ compiler to offload calling thread_local object destructors on thread program exit, to glibc. This is to overcome the possible complication of destructors of thread_local objects getting called after the DSO in which they're defined is unloaded by the dynamic linker. The DSO is marked as 'unloadable' if it has a constructed thread_local object and marked as 'unloadable' again when all the constructed thread_local objects defined in it are destroyed.
2013-02-14hppa: Remove unused lll_unlock_wake_cb.Carlos O'Donell
There hasn't been a use for lll_unlock_wake_cb since it was removed globally in 2007-05-29. This patch removes the function from hppa's lowlevellock.[ch] implementation.

2013-02-08Remove CHECK_N and bp-checks.h.Joseph Myers
2013-02-08ARM: Support loading unmarked objects from cache.Carlos O'Donell
ARM now supports loading unmarked objects from the dynamic loader cache. Unmarked objects can be used with the hard-float or soft-float ABI. We must support loading unmarked objects during the transition period from a binutils that does not mark objects to one that does mark them with the correct ELF flags.

2013-02-08Remove CHECK_1 and CHECK_1_NULL_OK.Joseph Myers
2013-02-05MIPS: Correct formatting of syscall wrapper `asm' specifiers.Maciej W. Rozycki
2013-02-05MIPS: Respect the legacy syscall restart convention.Maciej W. Rozycki
That convention requires the instruction immediately preceding SYSCALL to initialize $v0 with the syscall number. Then if a restart triggers, $v0 will have been clobbered by the syscall interrupted, and needs to be reinititalized. The kernel will decrement the PC by 4 before switching back to the user mode so that $v0 has been reloaded before SYSCALL is executed again. This implies the place $v0 is loaded from must be preserved across a syscall, e.g. an immediate, static register, stack slot, etc. The restriction was lifted with Linux 2.6.36 kernel release and no special requirements are placed around the SYSCALL instruction anymore, however we still support older kernel binaries.

2013-01-10tilegx: fix ldd to work with both tilegx64 and tilegx32Chris Metcalf
This uses the same ldd-rewrite.sed hook as other platforms, with the minor tweak that tilegx uses /lib (64-bit) and /lib32 (32-bit).

2012-12-28tile: support lll_futex_timed_wait_bitsetChris Metcalf
2012-12-21tile: fix DWARF bug in clone() for created threadChris Metcalf
Previously, we would see a bad frame in the gdb backtrace output, e.g.: (gdb) bt #0 foo () at foo.c:5 #1 0x000000aaaab68ee8 in start_thread () from /lib/libpthread.so.0 #2 0x000000aaaad01c88 in clone () from /lib/libc.so.6 #3 0x0000000000000000 in ?? () With this change the bogus frame #3 is gone and we have the same output as x86 does for the same program.
