Wouldn't it be possible to have a binary containing multiple versions of your program compiled optimized for various CPU configuration and have a switch at runtime which would select depending on your CPUid. I think intel have a compiler for that.

Yes, our github.com/google/highway does that for SSE4/AVX2/AVX-512. It targets at the level of instruction sets, though, not specific microarchitectures.
