As someone whose software heavily depends on SSE and AVX2 assembly code, we always do runtime detection. The SSE2 baseline of x86_64 is handy as there are a few things I can inline as a result, but there is no performance benefit to an AVX2 baseline, other than possibly the binary size dropping a bit as it no longer has to include the SSE2 versions of the functions. _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
