Summary: In r349534, objc arc implementation is switched to use intrinsics and at the same time, clang.arc.use is renamed to llvm.objc.clang.arc.use to make the naming more consistent. The side-effect of that is llvm no longer recognize it as intrinsics and codegen external references to it instead. Rather than upgrade the old intrinsics name to the new one and wait for the arc-contract pass to remove it, simply remove it in the bitcode upgrader. rdar://problem/48607063 Reviewers: pete, ahatanak, erik.pilkington, dexonsmith Reviewed By: pete, dexonsmith Subscribers: jkorous, jdoerfert, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D59112 llvm-svn: 355663
