I have not been able to find a way to test each in isolation, for a few reasons: 1) The ability to look-through non-i1 BinaryOperator's requires the ability to look through non-constant ICmps in order for it to ever trigger. 2) The ability to do LVI-powered PHI value determination only matters in cases that ProcessBranchOnPHI can't handle. Since it already handles all the cases without other instructions in the def-use chain between the PHI and the branch, it requires the ability to look through ICmps and/or BinaryOperators as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112611 91177308-0d34-0410-b5e6-96231b3b80d8
