2014-05-09S/390: Port of lock elision to System/zDominik Vogt
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.

2014-04-17PowerPC: Sync pthread_once with default implementationAdhemerval Zanella
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.
2014-04-11Fixed and unified pthread_once.Torvald Riegel
[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.
2014-04-09Move __PTHREAD_SPINS definition to architecture specific headerAdhemerval Zanella
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.
2014-03-26Fix dwarf2 unwinding through futex functions.Andi Kleen
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.

2014-03-17Fix __PTHREAD_MUTEX_HAVE_ELISION -Wundef warningWill Newton
ChangeLog: 2014-03-17 Will Newton <will.newton@linaro.org> * nptl/sysdeps/pthread/pthread.h: Check __PTHREAD_MUTEX_HAVE_ELISION is defined before testing its value.
2014-03-17Get rid of __LT_SPINLOCK_INITSiddhesh Poyarekar
We got rid of LinuxThreads in 2005, but we didn't remove __LT_SPINLOCK_INIT back then. Do it now. * nptl/sysdeps/pthread/bits/libc-lockP.h [defined NOT_IN_libc && !defined IS_IN_libpthread && __LT_SPINNOCK_INIT != 0]: Remove.

2014-02-05Fix tst-setgetname for Linux kernels < 2.6.33.Carlos O'Donell
Support for /proc/self/task/$tid/comm as added in Linux 2.6.33, therefore since the test tst-setgetname relies on this functionality to operate we must skip the test in kernels < 2.6.33. We wrap the checks with __ASSUME_PROC_PID_TASK_COMM such that in the future when we move arch_minimum_kernel to 2.6.33 we can remove this code.

2013-12-12Add test case for pthread_[sg]etname_np.Carlos O'Donell
This commit adds a testcase for pthread_setname_np and pthread_getname_np. The testcase itself has four tests to validate that these functions work as expected. The test is only enabled for Linux since it requires access to an alternate method for validating the functions work.
