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. |
