It does now, but failed to do so until r169695 due to a incompatibility of LLVM's makefiles and Fedora 17's version of python. It still reported a (false) green status, which is indeed confusing and probably a different bug in our buildbot infrastructure. The LLVM bots were unaffected, they're still running on Fedora 16.

Now the bot successfully runs all clang regression tests, which is great and very helpful by reporting new regressions early.
