   2
   3         * sysdeps/sparc/sparc64/pt-machine.h (MEMORY_BARRIER): Use membar,
   4         not stbar.
   5         (READ_MEMORY_BARRIER): Define.
   6         * spinlock.c (__pthread_spin_unlock): Use READ_MEMORY_BARRIER, not
   7         MEMORY_BARRIER.
   8         * internals.h (READ_MEMORY_BARRIER): Define if not defined in sysdep
   9         headers.

  11 2000-04-17  Ulrich Drepper  <drepper@redhat.com>
  12
  13         * sysdeps/unix/sysv/linux/i386/getcpuclockid.c
  14         (pthread_getcpuclockid): Don't compare thread_id with thread_self,
  15         use thread_handle().
  16
  17 2000-04-16  Ulrich Drepper  <drepper@redhat.com>
  18
  19         * condvar.c (pthread_cond_timedwait_relative): Don't test for owner
  20         if fast mutex is used.  Don't initialize `already_canceled' twice.
  21         Correctly test for return value of timedsuspend.
  22
  23         * pthread.c: Correct long-time braino.  We never set SA_SIGINFO and
  24         therefore don't need the _rt versions of the signal handlers.
  25

  35
  36         * pthread.c: Is __ASSUME_REALTIME_SIGNALS then avoid generating code
  37         to dynamically detect RT signals and avoid generating compatibility
  38         functions with old kernel.
  39         * restart.h (restart) [__ASSUME_REALTIME_SIGNALS]: Use
  40         __pthread_restart_new directly.
  41         (suspend) [__ASSUME_REALTIME_SIGNALS]: Use
  42         __pthread_wait_for_restart_signal directly.
  43         (timedsuspend) [__ASSUME_REALTIME_SIGNALS]: Use

  60         * semaphore.c (sem_timedwait): Use timedsuspend, don't duplicate
  61         the code.

 356         Redesigned how cancellation unblocks a thread from internal
 357         cancellation points (sem_wait, pthread_join,
 358         pthread_cond_{wait,timedwait}).
 359         Cancellation won't eat a signal in any of these functions
 360         (*required* by POSIX and Single Unix Spec!).
 361         * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
 362         simultaneous condition variable signal (not required by POSIX
 363         or Single Unix Spec, but nice).
 364         * spinlock.c: __pthread_lock queues back any received restarts
 365         that don't belong to it instead of assuming ownership of lock
 366         upon any restart; fastlock can no longer be acquired by two threads
 367         simultaneously.
 368         * restart.h: Restarts queue even on kernels that don't have
 369         queued real time signals (2.0, early 2.1), thanks to atomic counter,
 370         avoiding a rare race condition in pthread_cond_timedwait.

 502 1999-10-21  Xavier Leroy  <Xavier.Leroy@inria.fr>
 503
 504         * linuxthreads/pthread.c: For i386, wrap pthread_handle_sigrestart
 505         and pthread_handle_sigcancel with functions that restore

1632         Since sigset_t no longer fits in a register, we can't pass in the
