craig.topper added a comment. @erichkeane are you ok with this code for now? I think validateCPUIs gives you what you need at least for Sema support for target attribute. You'll probably need to refactor the CG code to make your ifunc resolver. But I think you need to do that for the existing feature code that's similar anyway. And from our side conversation it sounds like you're not ready for that yet.
