I would imagine they write separate asm for x86, x86_64, and the various instruction set extensions that exist.

- __s 8y agoA project may even go so far as to write different asm for the same ISA for different architectures in order to optimize for specific pipeline behavior or whatnot https://github.com/z-classic/libgmp/tree/master/mpn/x86_64 https://github.com/z-classic/libgmp/tree/master/mpn/x86_64
