New Revision: 178101
URL: http://llvm.org/viewvc/llvm-project?rev=178101&view=rev
Log:
Added back in the test for arc-annotations.
The test was removed since I had not turned off the test during release
builds. This fails since ARC annotations support is conditionally
compiled out during release builds. I added the proper requires header
to assuage this issue.
