Summary: This patch was introduced one year ago, but because my google account was disabled, I didn't get email with failing buildbot and I missed revert of this commit. There was small but in test regex. I am back. Reviewers: rsmith, rengolin Subscribers: nlewycky, rjmccall, cfe-commits Differential Revision: https://reviews.llvm.org/D26117 llvm-svn: 285497
