2005-01-26  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/unix/sysv/linux/i386/sysdep.h
	(SYSCALL_ERROR_HANDLER_TLS_STORE): Remove unnecessary 0 imm.
nptl/
	* sysdeps/unix/sysv/linux/i386/i486/sem_trywait.S (__new_sem_trywait):
	Use direct %gs segment access or, if NO_TLS_DIRECT_SEG_REFS,
	at least gotntpoff relocation and addition.
	* sysdeps/unix/sysv/linux/i386/i486/sem_timedwait.S (sem_timedwait):
	Likewise.
	* sysdeps/unix/sysv/linux/i386/i486/sem_post.S (__new_sem_post):
	Likewise.
	* sysdeps/unix/sysv/linux/i386/i486/sem_wait.S (__new_sem_wait):
	Likewise.

2005-01-23  Roland McGrath  <roland@redhat.com>

	* sysdeps/i386/Makefile (defines): If -mno-tls-direct-seg-refs appears
	in $(CFLAGS), add -DNO_TLS_DIRECT_SEG_REFS.
	* sysdeps/unix/sysv/linux/i386/sysdep.h [USE___THREAD]
	(SYSCALL_ERROR_HANDLER) [NO_TLS_DIRECT_SEG_REFS]: Load thread pointer
	from %gs:0 and add to that value, rather that direct %gs:OFFSET access.
	* sysdeps/unix/i386/sysdep.S [NO_TLS_DIRECT_SEG_REFS]: Likewise.
