Update.
2004-01-13 Ulrich Drepper <drepper@redhat.com>
* sysdeps/x86_64/dl-machine.h: Include <tls.h>.
* elf/rtld.c (_dl_start_final): Initialze __libc_stack_end here.
* sysdeps/generic/dl-sysdep.c: Define __libc_stack_end with
rtld_hidden_def and move into .data.rel.ro section.
* sysdeps/generic/ldsodefs.h: Declare __libc_stack_end with
rtld_hidden_proto.
* sysdeps/generic/libc-start.c: Only initialize __libc_stack_end here
if !SHARED.
* sysdeps/unix/sysv/linux/dl-execstack.c
(_dl_make_stack_executable): Move common code in front. Use
__builtin_expect.
