> Yes, exactly. AFAICT you're implementing functionality which will be removed. More generally, you might want to check whether any builtins generate platform-specific IR instructions. If no, there is (or should) probably be a generic version, which the x86 builtins can use instead. That way, instead of adding code, you might actually remove code to implement new features.
Thanks, that's what I wanted to clarify. That also means i'll have to have a new implementation targeting __builtin_elementwise_sqrt instead.
