2013-06-10x86*: Return syscall error for lll_futex_wake.Carlos O'Donell
It is very very possible that the futex syscall returns an error and that the caller of lll_futex_wake may want to look at that error and propagate the failure. This patch allows a caller to see the syscall error. There are no users of the syscall error at present, but future cleanups are now be able to check for the error. -- nplt/ 2013-06-10 Carlos O'Donell <carlos@redhat.com> * sysdeps/unix/sysv/linux/i386/lowlevellock.h (lll_futex_wake): Return syscall error. * sysdeps/unix/sysv/linux/x86_64/lowlevellock.h (lll_futex_wake): Return syscall error.

2013-04-07sem_post.c: Include atomic.h.Carlos O'Donell
The sem_post.c file uses atomic functions without including atomic.h. Add `#include <atomic.h>' to the file to prevent any compile time warnings when other headers change and atomic.h isn't implicitly included. --- nptl/ 2013-04-07 Carlos O'Donell <carlos@redhat.com> * sysdeps/unix/sysv/linux/sem_post.c: Include atomic.h.
2013-04-04Fix static build when configured with --disable-hidden-pltSiddhesh Poyarekar
Fixes BZ #15337. Static builds fail with the following warning: /home/tools/glibc/glibc/nptl/../nptl/sysdeps/unix/sysv/linux/x86_64/cancellation.S:80: undefined reference to `__GI___pthread_unwind' When the source is configured with --disable-hidden-plt. This is because the preprocessor conditional in cancellation.S only checks if the build is for SHARED, whereas hidden_def is defined appropriately only for a SHARED build that will have symbol versioning *and* hidden defs are enabled. The last case is false here.

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.

2012-11-05[S390,PPC] Implement FUTEX_WAIT_BITSET for timedwait functionsSiddhesh Poyarekar
Since the FUTEX_WAIT operation takes a relative timeout, the pthread_cond_timedwait and other timed function implementations have to get a relative timeout from the absolute timeout parameter it gets before it makes the futex syscall. This value is then converted back into an absolute timeout within the kernel. This is a waste and has hence been improved upon by a FUTEX_WAIT_BITSET operation (OR'd with FUTEX_CLOCK_REALTIME to make the kernel use the realtime clock instead of the default monotonic clock). This was implemented only in the x86 and sh assembly code and not in the C code. This patch implements support for FUTEX_WAIT_BITSET whenever available (since linux-2.6.29) for s390 and powerpc.
