It is very annoying for gas to warn NOPS generated from macros. It
causes many "make check" failures in gcc. Here is a patch.

2001-06-06 H.J. Lu <hjl@gnu.org>
* config/tc-mips.c (warn_nops): New variable. Set to 0 to
disable warning about all NOPS that the assembler generates.
(macro): Warn NOPS generated only if warn_nops is not 0.
(md_shortopts): Add `n'.
(md_parse_option): Set warn_nops to 1 for `n'.
