+; This is supposed to be testing BranchFolding's common
+; code hoisting logic, but has been erroneously passing due
+; to there being a redundant xorl in the entry block
+; and no common code to hoist.
+; However, now that MachineSink sinks the redundant xor
+; hoist-common looks at it and rejects it for hoisting,
+; which causes this test to fail.
+; Since it seems this test is broken, marking XFAIL for now
+; until someone decides to remove it or fix what it tests.
