+Subject: [PATCH] [PATCH][llvm] Make source-interleave-prefix test case
+ compatible with llvm-test
+
+llvm-test runs test from a directory that's not the upstream one, and that leads
+to some false positive. Workaround this by forcing the current working
+directory.

-Since AGR clobbers CC it should not be used here.
