NAK. This is wrong. -munroll-only-small-loops does not enable loop unrolling; doing that with a machine flag is completely unmaintainable, also for people using different targets. Something in your patch was wrong, please fix that (or revert the patch). You should not have to touch config/rs6000/ at all. Segher
