--- Comment #6 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
We should keep this issue open for a different problem, though. When swap
optimization doesn't succeed on such a loop, we don't end up optimizing away
the xxlnand associated with the vperm on Power8. Currently that is only done
as part of swap optimization. It's a minor savings but worth doing.
