2003-11-14 David Mosberger <davidm@hpl.hp.com> * sysdeps/unix/sysv/linux/ia64/sysdep.h (GAS_ALIGN_BREAKS_UNWIND_INFO): Define this macro to indicate that all existing GAS versions have a problem with .align inside a function. * sysdeps/ia64/memccpy.S: Work around GAS_ALIGN_BREAKS_UNWIND_INFO bug. * sysdeps/ia64/memcpy.S: Likewise. * sysdeps/ia64/memset.S: Likewise. * sysdeps/ia64/memmove.S: Likewise. Also move the jump-table to out of .text into .rodata, where it belongs. * sysdeps/unix/sysv/linux/ia64/pipe.S: There is no need to save/restore input-arguments, because they're necessarily preserved by the kernel to support syscall-restart.
