You'll typically get something like this:
Making Clang 'lit.site.cfg' file...
--- Running clang tests for x86_64-apple-darwin10.0.0 ---
lit.py: lit.cfg:146: note: using clang: '/Users/dgregor/Projects/llvm-
lit.py: lit.cfg:151: note: using clang-cc: '/Users/dgregor/Projects/
-- Testing: 1625 tests, 2 threads --
once the tests finish, the progress bar will go away and you'll get a
Testing Time: 58.61s
Expected Passes : 1610
Expected Failures : 15
there's no other output unless there is a failure, which shouldn't
happen. If you really want to see every test go by, pass the make

Ignore it. At some point, it will disappear. llvm/utils/lit/lit.py is
what drives Clang testing now ("make all" in tools/clang/test just

The verbose output shows all passes/fails. Generally, it's only the
fails that matter, and there should never be any not marked XFAIL.
