What makes those generated functions explicitly unsafe? Isn't it only the fact that the cpu might not have those instructions? If so, then isn't the runtime generate function completely safe, because it ensures at runtime that the instructions that it will use do exist? |

simd_xxx_generatemacros are explictlyunsafe.This has an impact for consumers of this crate, so a (minor) version bump might be applicable.
