For reference, here are the results from the last time I ran it with llvm-gcc, about a month ago:

# of expected passes            39621
# of unexpected failures        1112
# of unexpected successes       2
# of expected failures          59
# of unresolved testcases       80
# of untested testcases         280
# of unsupported tests          1073

Many of the 9000 extra failures are probably llvm-gcc/clang differences that are nothing to do with you, though.  The best way to get useful info out of this is to run it with and without the patch you're testing, and compare.
