Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |uros at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Oops, no, that change only changed xorpd into pxor. The actual change that introduced the xoring was r201308, aka PR57954 and PR57988. So can you explain why you think the xors aren't necessary to avoid partial sse dependency stalls?
