How to make Cargo crate enable instruction set if the compiling hardware supports it?
My library runs substantially faster on x86 when compiled with the avx2, bmi1, bmi2 instruction sets, but even today not all hardware supports those. I think ideally the build would check whether the hardware supports these instruction sets and compile with them if so. How can I best make this happen?
