I'm working on packaging a project that makes use of AVX/AVX2/NEON to process and improve the quality of low bitrate human speech:
https://github.com/mozilla/LPCNet I'm having trouble determining what the base CPU targets for Fedora can accommodate. For example, ss it safe to assume AVX2 on x86_64? At this time upstream only supports AVX/AVX2/NEON, but if they did add support for SVE on aarch64, can I use it? What about VSX on ppc64le? It doesn't look like I have any options on s390x since the base is "-march=zEC12+" which from what I can tell doesn't support the extended intrinsics required. I found this but all the information seems to be wildly out of date and even if it wasn't it doesn't tell me what I need to know: https://fedoraproject.org/wiki/Architectures This is very much an area I'm not familiar with. Thanks, Richard
