[PATCH] D138796: ObjCARC: Try to fix faulty tests

[Akira Hatanaka via Phabricator via llvm-commits]

ahatanak added a comment.

ARC optimizer was previously removing the retain/release pair, but it's not clear to me why it was safe to do so. There is a load that loads an ivar of the object before the call to `@llvm.objc.release`, so the object has to be kept alive at least until that point.

I have to investigate when it stopped removing the pair.
