From 00a2f9aa41a4f2a441c3b9787ca1a7701632de5f Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 26 Aug 1998 16:00:46 +0000 Subject: Update. 1998-08-26 15:46 Ulrich Drepper * 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. --- linuxthreads/sysdeps/sparc/sparc32/pt-machine.h | 6 +++++- linuxthreads/sysdeps/sparc/sparc64/pt-machine.h | 6 +++++- 2 files changed, 10 insertions(+), 2 deletions(-) (limited to 'linuxthreads/sysdeps/sparc') diff --git a/linuxthreads/sysdeps/sparc/sparc32/pt-machine.h b/linuxthreads/sysdeps/sparc/sparc32/pt-machine.h index 13f78e319a..7eea8d400c 100644 --- a/linuxthreads/sysdeps/sparc/sparc32/pt-machine.h +++ b/linuxthreads/sysdeps/sparc/sparc32/pt-machine.h @@ -1,6 +1,6 @@ /* Machine-dependent pthreads configuration and inline functions. sparc version. - Copyright (C) 1996, 1997 Free Software Foundation, Inc. + Copyright (C) 1996, 1997, 1998 Free Software Foundation, Inc.
