(__pthread) [ENABLE_TLS]: Add TCB member. [ENABLE_TLS] (_dl_allocate_tls, _dl_deallocate_tls): Declare; from glibc. * sysdeps/mach/hurd/pt-sysdep.h (__thread_set_pcsp): Rename to __thread_set_pcsptp. Add SET_TP and TP parameters. Change all callers. * sysdeps/mach/hurd/i386/pt-machdep.c (__thread_set_pcsptp): Imlement TLS support. * sysdeps/mach/hurd/i386/pt-setup.c (__pthread_setup): Likewise. --- pthread/pt-exit.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'pthread/pt-exit.c') diff --git a/pthread/pt-exit.c b/pthread/pt-exit.c index 7484ffd..941526a 100644 --- a/pthread/pt-exit.c +++ b/pthread/pt-exit.c @@ -1,5 +1,5 @@ /* Thread termination. - Copyright (C) 2000, 2002, 2005 Free Software Foundation, Inc. + Copyright (C) 2000, 2002, 2005, 2007 Free Software Foundation, Inc.
