--- Comment #11 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Fixed on the trunk, this patch is not worth backporting even though this is a
regression; it is a missed optimization and one which one that happens only one
specific condition (even/odd checks) and it took 5 years for someone to report.
