--- 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?).
