Update.
2002-07-19 Ulrich Drepper <drepper@redhat.com>
* 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 <tls.h>. 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.
