It’s considerably more onerous than just compiling to a single/multiple microarchitecture(s) though. Plus when you do this, you need to split out this code to be conditionally compiled so that you can support other architectures like ARM.
- janwas 3y agoHere is an example on how to do this using github.com/google/highway: https://gcc.godbolt.org/z/zP7MYe9Yf https://gcc.godbolt.org/z/zP7MYe9Yf You write the code only once and do not have to worry about any #pragma/conditional compilation. Just copy-paste about a dozen lines of boilerplate, link with the Highway library, and done. Disclosure: I am the main author; happy to discuss.
