*	[ObjC][ARC] Upgrade calls to ARC runtime functions to intrinsic calls if	Akira Hatanaka	2019-08-08	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	the bitcode has the arm64 retainAutoreleasedReturnValue marker The ARC middle-end passes stopped optimizing or transforming bitcode that has been compiled with old compilers after we started emitting calls to ARC runtime functions as intrinsic calls instead of normal function calls in the front-end and made changes to teach the ARC middle-end passes about those intrinsics (see r349534). This patch converts calls to ARC runtime functions that are not intrinsic functions to intrinsic function calls if the bitcode has the arm64 retainAutoreleasedReturnValue marker. Checking for the presence of the marker is necessary to make sure we aren't changing ARC function calls that were originally MRR message sends (see r349952). rdar://problem/53280660 Differential Revision: https://reviews.llvm.org/D65902 llvm-svn: 368311
*	[Bitcode] Fix bitcode compatibility issue with clang.arc.use intrinsic	Steven Wu	2019-03-08	1	-0/+14
	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
