* S/390: Port of lock elision to System/zDominik Vogt2014-05-0914-2/+584
| | | | | | | | | | Added support for TX lock elision of pthread mutexes on s390 and s390x. This may improve lock scaling of existing programs on TX capable systems. The lock elision code is only built with --enable-lock-elision=yes and then requires a GCC version supporting the TX builtins. With lock elision default mutexes are elided via __builtin_tbegin, if the cpu supports transactions. By default lock elision is not enabled and the elision code is not built.

* PowerPC: Sync pthread_once with default implementationAdhemerval Zanella2014-04-171-110/+0
| | | | | | | | This patch removes the arch specific powerpc implementation and instead uses the linux default one. Although the current powerpc implementation already constains the required memory barriers for correct initialization, the default implementation shows a better performance on newer chips.
* Fixed and unified pthread_once.Torvald Riegel2014-04-112-93/+131
| | | | | | | [BZ #15215] This unifies various pthread_once architecture-specific implementations which were using the same algorithm with slightly different implementations. It also adds missing memory barriers that are required for correctness.
* Move __PTHREAD_SPINS definition to architecture specific headerAdhemerval Zanella2014-04-096-13/+15
| | | | | | | This patch moves the __PTHREAD_SPINS definition to arch specific header since pthread_mutex_t layout is also arch specific. This leads to no need to defining __PTHREAD_MUTEX_HAVE_ELISION and thus removing of the undefined compiler warning.
* Fix dwarf2 unwinding through futex functions.Andi Kleen2014-03-262-336/+40
| | | | | | | | | | | | | | | | | | | When profiling programs with lock problems with perf record -g dwarf, libunwind can currently not backtrace through the futex and unlock functions in pthread. This is because they use out of line sections, and those are not correctly described in dwarf2 (I believe needs dwarf3 or 4). This patch first removes the out of line sections. They only save a single jump, but cause a lot of pain. Then it converts the now inline lock code to use the now standard gas .cfi_* commands. With these changes libunwind/perf can backtrace through the futex functions now. Longer term it would be likely better to just use C futex() functions on x86 like all the other architectures. This would clean the code up even more.
