Hi Rechard, I recommend using the simde (SIMD Everywhere) library for the packaging and contribution to the upstream. https://github.com/nemequ/simde You do not need to care about the availability by arch or compiler when using this library. simde-devel is available in Fedora stable versions now. [1] libsimde-dev is available in Debian, hopefully soon available to the stable versions and Ubuntu. [2] Here are the actual examples 1 [3] and 2 [4] implementing it.
