New Revision: 135740
URL: http://llvm.org/viewvc/llvm-project?rev=135740&view=rev
Log:
objective-c: Any use of @synthesize or @dynamic lexically after a method (or C function) implementation
will be rejected with a compilation error in ARC mode, and a compiler warning otherwise.
This may cause breakage in non-arc (and arc) tests which don't expect warning/error. Feel free
to fix the tests, or reverse the patch, if I am unavailable. // rdar://9818354 - WIP
