Prior to this patch, IfConverter may widen the cases where a sequence of instructions were executed because of the way it uses nested predicates. This result in incorrect execution. For instance, Let A be a basic block that flows conditionally into B and B be a predicated block. B can be predicated with A.BrToBPredicate into A iff B.Predicate is less "permissive" than A.BrToBPredicate, i.e., iff A.BrToBPredicate subsumes B.Predicate. The IfConverter was checking the opposite: B.Predicate subsumes A.BrToBPredicate. <rdar://problem/14379453> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187071 91177308-0d34-0410-b5e6-96231b3b80d8 |
