What's preventing vectorization with sse2 (or other architecture' base SIMD) anyhow, if anything? Use something like gcc -Ofast -fopt-info-vec-missed on the performance-critical parts for clues. Use -Ofast if you don't care about conforming maths, which you presumably don't, especially if using NEON. _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx 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@xxxxxxxxxxxxxxxxxxxxxxx
