Bob Wilson 74b0ccc577 Fix pr4195: When iterating through predecessor blocks, break out of the loop ... after finding the (unique) layout predecessor. Sometimes a block may be listed more than once, and processing it more than once in this loop can lead to inconsistent values for FtTBB/FtFBB, since the AnalyzeBranch method does not clear these values. There's no point in continuing the loop regardless. The testcase for this is reduced from the 2003-05-02-DependentPHI SingleSource test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71536 91177308-0d34-0410-b5e6-96231b3b80d8		2009-05-12 03:48:10 +00:00
