Lu <h...@gcc.gnu.org>: https://gcc.gnu.org/g:dd9b529f08c3c6064c37234922d298336d78caf7 commit r10-6298-gdd9b529f08c3c6064c37234922d298336d78caf7 Author: H.J. Lu <hjl.to...@gmail.com> Date: Tue Jan 28 11:32:56 2020 -0800 i386: Prefer TARGET_AVX over TARGET_SSE_TYPELESS_STORES movaps/movups is one byte shorter than movdqa/movdqu. But it isn't the case for AVX nor AVX512. This patch prefers TARGET_AVX over TARGET_SSE_TYPELESS_STORES and adjust vmovups checks in assembly ouputs. gcc/ PR target/91461 * config/i386/i386.md (*movoi_internal_avx): Remove TARGET_SSE_TYPELESS_STORES check.
