linuxthreads/ChangeLog

   1 1999-10-21  Xavier Leroy  <Xavier.Leroy@inria.fr>
   2
   3         * linuxthreads/pthread.c: For i386, wrap pthread_handle_sigrestart
   4         and pthread_handle_sigcancel with functions that restore
   5         %gs from the signal context.  For each signal handling function,
   6         two wrappers are required, one for a non-RT signal and one for
   7         a RT signal.
   8         * linuxthreads/signal.c: For i386, add code to restore %gs
   9         from the signal context in pthread_sighandler and
  10         pthread_sighandler_rt.
  11

  39
  40         * manager.c (__pthread_manager) [REQ_POST]: Use __new_sem_post
  41         directly instead of calling sem_post which should not be necessary
  42         but is faster and might help in some case to work around problems.

1107         * sysdeps/pthread/libc-lock.h: Define __libc_key_create,
1108         __libc_getspecific, __libc_setspecific, and __libc_key_t.
1109         * sysdeps/pthread/stdio-lock.h: Don't care for implementation not
1110         using libio.

1131         Since sigset_t no longer fits in a register, we can't pass in the
1132         thread's initial mask so easily.  Take this opportunity to simplify
1133         the clone implementation by only accepting a single void* argument.
1134
1135         * linuxthreads/manager.c (__pthread_manager): Put thread vitals
1136         in the thread struct instead of as arguments through clone.
1137         (pthread_start_thread): Look for them there.
1138         * linuxthreads/internals.h (struct _pthread): Add p_initial_fn,
1139         p_initial_fn_arg, p_initial_mask.  Fix __pthread_manager proto.
1140         * linuxthreads/pthread.c (pthread_initialize_manager): Revise
1141         clone invocation.
