--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I've attached two rotate patches to PR57157. They seem to improve #c6 runtime slightly (from: real 0m6.303s user 0m6.293s sys 0m0.000s to: real 0m5.920s user 0m5.913s sys 0m0.000s ) but guess there are other issues to look at (perhaps RA can be one thing, what else?).
