[PATCH] D112349: [Verifier] Add verification logic for GlobalIFuncs

[Itay Bookstein via Phabricator via llvm-commits]

ibookstein added a comment.

Note that (as the examples demonstrate) clang self-verifies and checks among other things that ifuncs that it emits point to definitions; this happens in `CodeGenModule::checkAliases()`.
I haven't read the cpu_specific/cpu_dispatch-related code in CodeGenModule yet, but I'm guessing that it doesn't register the generated aliases/ifuncs into the `CodeGenModule::Aliases` vector for deferred verification, which is why this didn't trigger the same error that my ifunc example did so far.
