Unless others have comments, this looks good to go in to me.



================
Comment at: llvm/lib/CodeGen/GlobalISel/CombinerHelper.cpp:392
+  CmpInst::Predicate InversePred = CmpInst::getInversePredicate(
+      (CmpInst::Predicate)CmpMI->getOperand(1).getPredicate());
+
----------------
Orthogonal to this patch - I've found that MachineOperand::getPredicate returning an unsigned and users having to explicitly cast to Predicate is a little annoying. What do you think of getPredicate returning Predicate type (in a separate patch)? In my use cases I've almost never used the unsigned value without casting to Predicate.
