Update.
2003-03-13 Jakub Jelinek <jakub@redhat.com>
* sysdeps/unix/sysv/linux/ia64/sysdep.h (BREAK_INSN_1, BREAK_INSN,
ASM_OUTARGS_0, ASM_OUTARGS_1, ASM_OUTARGS_2, ASM_OUTARGS_3,
ASM_OUTARGS_4, ASM_OUTARGS_5, ASM_OUTARGS_6): Define.
(INTERNAL_SYSCALL, INLINE_SYSCALL): Use it. Make syscall arguments
clobbered by the syscall.
(ASM_ARGS_1, ASM_ARGS_2, ASM_ARGS_3, ASM_ARGS_4, ASM_ARGS_5,
ASM_ARGS_6): Change constraints from r to index of corresponding
output register.
* sysdeps/unix/sysv/linux/ia64/clone2.S (__clone2): Swap
ptid and ctid to match kernel.
* sysdeps/unix/sysv/linux/ia64/system.c (FORK): Likewise.
* sysdeps/powerpc/powerpc64/elf/configure.in: Remove
* sysdeps/powerpc/powerpc64/elf/configure: Regenerated.
