--- Comment #2 from Filip Kastl <pheeck at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #1) > Can you try to revert r14-9692 if that commit isn't the cause? I have tried reverting r14-9692 and that indeed removed the slowdown. The benchmark ran as fast as on r14-9649-gbb04a11418f54c. So it seems that r14-9692 is the cause of this slowdown.
