[PATCH] D108479: [Clang] Add __builtin_addressof_nocfi

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

`std::addressof(&someFunction)` certainly ought to return a signed pointer under ptrauth, so if your goal here is to get a completely unadorned symbol address, I think you do need a different builtin, and it probably ought to return a `void*` to emphasize that it shouldn't be used as a normal value.  Maybe it should even be semantically restricted to require a constant decl reference as its operand?  Related and perhaps illuminating question: if it were implementable, would you also want to force the suppression of lazy-binding thunks and/or decorations like the THUMB bit?
