--- Comment #3 from Uroš Bizjak <ubizjak at gmail dot com> --- (In reply to Jakub Jelinek from comment #1) > Created attachment 31463 [details] > gcc49-pr59539.patch >From a quick look at the patch, the proposed patch doesn't support masked insns. I think it is better to introduce corresponding sse.md expanders for UNSPEC_STOREU and UNSPEC_LOADU insns. These expanders will either generate UNSPEC_* pattern or "normal" (masked) move in case of TARGET_AVX.
