Update.
1998-08-26 15:46 Ulrich Drepper <drepper@cygnus.com> * internals.h: Define THREAD_GETMEM and THREAD_SETMEM to default if not already defined. (struct _pthread_descr_struct): Add p_self and p_nr field. * manager.c (__pthread_handles): Define second element to point to manager thread. (__pthread_handles_num): Initialize to 2. (__pthread_manager): Use INIT_THREAD_SELF with two arguments. (pthread_start_thread): Likewise. (pthread_handle_create): Start search for free slot at entry 2. Initialize new fields p_self and p_nr. Call __clone with CLONE_PTRACE if available. (pthread_free): Call FREE_THREAD_SELF if available. * pthread.c (__pthread_initial_thread): Initialize new fields. (__pthread_manager_thread): Likewise. (__pthread_initialize_manager): Call __clone with CLONE_PTRACE. * cancel.c: Use THREAD_GETMEM and THREAD_SETMEM to access the elements of the thread descriptor. * condvar.c: Likewise. * errno.c: Likewise. * join.c: Likewise. * manager.c: Likewise. * pthread.c: Likewise. * ptlongjmp.c: Likewise. * semaphore.c: Likewise. * signals.c: Likewise. * specific.c: Likewise. * spinlock.c: Likewise. * sysdeps/alpha/pt-machine.h (INIT_THREAD_SELF): Add extra parameter. * sysdeps/i386/useldt.h: New file. * sysdeps/i386/i686/pt-machine.h: Show how to use this file. * sysdeps/sparc/sparc32/pt-machine.h: Define THREAD_GETMEM and THREAD_SETMEM using __thread_self. * sysdeps/sparc/sparc64/pt-machine.h: Likewise.
