Bug ID: 98521 Summary: [x86] Missing/incorrect XOP functions Product: gcc Version: 10.2.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: e...@coeus-group.com Target Milestone: --- _mm256_cmov_si256 is missing from xopintrin.h. It is present on clang and Visual Studio, and mentioned in AMD's documentation at https://developer.amd.com/wordpress/media/2012/10/New-Bulldozer-and-Piledriver-Instructions.pdf Additionally, _mm_frcz_ss and _mm_frcz_sd take two arguments in GCC's header but should only take one (as they do in clang and VS).
