[PATCH] D62433: [ObjC][ARC] Delete ObjC runtime calls if the argument is a global variable

[Michael Gottesman via Phabricator via llvm-commits]

gottesmm added a comment.

I don't remember. That being said, this should be a conservative optimization. What if someone adds in the future a different global where this isn't a no-op. Is it possible if you know what the global is to add a whitelist that you only care about those 2 things.
