expr.c (emit_block_move_via_movmem): Fix expected_align parameter.
2008-07-08 Raksit Ashok <raksit@google.com>
* expr.c (emit_block_move_via_movmem): Fix expected_align parameter.
(set_storage_via_setmem): Fix expected_align parameter.
* doc/invoke.texi (i386 and x86-64 Options): Add a couple of options
missing from the list.
* doc/md.texi (movmem): Explicitly state that expected alignment is
to be expressed in bytes.
(setmem): Explicitly state that expected alignment is to be expressed
in bytes.
