From 739d440d2a748be4b0139d4e5e0a566098abfcec Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 20 Jul 2002 01:14:41 +0000 Subject: Update. 2002-07-19 Ulrich Drepper * configure.in: Add test for __thread support in compiler. * config.h.in: Add HAVE___THREAD. * Makefile (headers): Remove errno.h, sys/errno.h, and bits/errno.h. * include/sys/errno.h: Moved to... * stdlib/sys/errno.h: ...here. New file. * stdlib/errno.h: New file. Moved from... * include/errno.h: ...here. Changed into an internal header defining libc-local things like __set_errno. * stdlib/Makefile (headers): Add errno.h, sys/errno.h, and bits/errno.h. * elf/dl-minimal.c: Include . Define errno as thread-local variable if USE_TLS && HAVE___THREAD. Don't define __errno_location either. * elf/rtld.c (_dl_start): Add code to initialize TLS for ld.so from... (_dl_start_final): ...here. Add code to initialize tls elements from bootstrap_map. * sysdeps/generic/errno-loc.c: Define errno as thread-local variable if USE_TLS && HAVE___THREAD. * sysdeps/generic/bits/errno.h: Remove __set_errno definition. * sysdeps/mach/hurd/bits/errno.h: Likewise. * sysdeps/standalone/arm/bits/errno.h: Likewise. * sysdeps/standalone/bits/errno.h: Likewise. * sysdeps/unix/bsd/bsd4.4/bits/errno.h: Likewise. * sysdeps/unix/sysv/aix/bits/errno.h: Likewise. * sysdeps/unix/sysv/hpux/bits/errno.h: Likewise. * sysdeps/unix/sysv/linux/bits/errno.h: Likewise. * sysdeps/unix/sysv/linux/hppa/bits/errno.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/errno.h: Likewise. * sysdeps/unix/sysv/sysv4/solaris2/bits/errno.h: Likewise. * sysdeps/i386/dl-machine.c (elf_machine_rel) [RTLD_BOOTSTRAP]: Don't use GL(dl_rtld_map), use map parameter. * sysdeps/sh/dl-machine.h (elf_machine_rela): Likewise. * sysdeps/unix/sysv/linux/i386/sysdep.S: Define errno in .tbss if USE_TLS && HAVE___THREAD. * sysdeps/unix/sysv/linux/i386/sysdep.h: Unify SETUP_PIC_REG definitions. If USE_TLS && HAVE___THREAD store errooor value using TLS code sequence. * sysdeps/unix/sysv/linux/i386/i686/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/getcwd.c: No real need to restore errno. * sysdeps/unix/sysv/linux/grantpt.c: Likewise. * sysdeps/unix/sysv/linux/internal_statvfs.c: Likewise. * sysdeps/unix/sysv/linux/msgctl.c: Likewise. * sysdeps/unix/sysv/linux/readv.c: Likewise. * sysdeps/unix/sysv/linux/writev.c: Likewise. --- sysdeps/generic/errno-loc.c | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) (limited to 'sysdeps/generic/errno-loc.c') diff --git a/sysdeps/generic/errno-loc.c b/sysdeps/generic/errno-loc.c index 44fedf41f0..bda9fa4211 100644 --- a/sysdeps/generic/errno-loc.c +++ b/sysdeps/generic/errno-loc.c @@ -1,6 +1,6 @@ /* MT support function to get address of `errno' variable, non-threaded version. - Copyright (C) 1996, 1998 Free Software Foundation, Inc. + Copyright (C) 1996, 1998, 2002 Free Software Foundation, Inc.
