2003-07-08 Jakub Jelinek <jakub@redhat.com> * pthreadP.h (__pthread_unwind_next, __pthread_register_cancel, __pthread_unregister_cancel): Add prototypes and hidden_proto. * unwind.c (__pthread_unwind_next): Add hidden_def. * cleanup.c (__pthread_register_cancel, __pthread_unregister_cancel): Likewise. * sysdeps/unix/sysv/linux/i386/i486/sem_wait.S (__new_sem_wait): Use HIDDEN_JUMPTARGET to jump to __pthread_unwind. * sysdeps/unix/sysv/linux/i386/i486/sem_timedwait.S (sem_timedwait): Likewise. * sysdeps/unix/sysv/linux/x86_64/sem_wait.S (sem_wait): Likewise. * sysdeps/unix/sysv/linux/x86_64/sem_timedwait.S (sem_timedwait): Likewise. * sysdeps/unix/sysv/linux/i386/pthread_once.S (__pthread_once): Use HIDDEN_JUMPTARGET to call __pthread_register_cancel, __pthread_unregister_cancel and __pthread_unwind_next.
