   8         * internals.h (struct _pthread_descr_struct): Reorganization.
   9         Allocate room for 16 pointers at head of the structure for future
  10         thread-local data handling.  Move p_self member in this area.
  11         * manager.c (pthread_handle_create): Adjust use of p_self.

  75         (pthread_getcpuclockid): Don't compare thread_id with thread_self,
  76         use thread_handle().
  77
  78 2000-04-16  Ulrich Drepper  <drepper@redhat.com>
  79
  80         * condvar.c (pthread_cond_timedwait_relative): Don't test for owner
  81         if fast mutex is used.  Don't initialize `already_canceled' twice.
  82         Correctly test for return value of timedsuspend.
  83

  97         * pthread.c: Is __ASSUME_REALTIME_SIGNALS then avoid generating code
  98         to dynamically detect RT signals and avoid generating compatibility
  99         functions with old kernel.

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

 399         * queue.h (queue_is_empty): New function.

 417         Redesigned how cancellation unblocks a thread from internal
 418         cancellation points (sem_wait, pthread_join,
 419         pthread_cond_{wait,timedwait}).
 420         Cancellation won't eat a signal in any of these functions
 421         (*required* by POSIX and Single Unix Spec!).
 422         * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
 423         simultaneous condition variable signal (not required by POSIX
 424         or Single Unix Spec, but nice).
 425         * spinlock.c: __pthread_lock queues back any received restarts
 426         that don't belong to it instead of assuming ownership of lock
 427         upon any restart; fastlock can no longer be acquired by two threads
 428         simultaneously.
 429         * restart.h: Restarts queue even on kernels that don't have
 430         queued real time signals (2.0, early 2.1), thanks to atomic counter,
 431         avoiding a rare race condition in pthread_cond_timedwait.
 432
 433 1999-12-31  Andreas Jaeger  <aj@suse.de>
 434
 435         * internals.h: Remove duplicate prototype declarations.

 563 1999-10-21  Xavier Leroy  <Xavier.Leroy@inria.fr>
 564
 565         * linuxthreads/pthread.c: For i386, wrap pthread_handle_sigrestart
 566         and pthread_handle_sigcancel with functions that restore
 567         %gs from the signal context.  For each signal handling function,
