[LLVMdev] Marking a test suite test XFAIL

[Patrick Alexander Simmons]

 From http://llvm.org/docs/TestingGuide.html

Some tests are known to fail. Some are bugs that we have not fixed yet; 
others are features that we haven't added yet (or may never add). In 
DejaGNU, the result for such tests will be XFAIL (eXpected FAILure). In 
this way, you can tell the difference between an expected and unexpected 
failure.

The tests in the test suite have no such feature at this time. If the 
test passes, only warnings and other miscellaneous output will be 
generated. If a test fails, a large <program> FAILED message will be 
displayed. This will help you separate benign warnings from actual test 
failures.

Does this mean there is no way to selectively disable a backend or to 
mark a test suite test XFAIL?

Thanks,
