================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:22807
+
+  // fold vp_mul X, (splat 0), Mask, EVL -> vp_select Mask, undef, (splat 0),
+  // EVL
----------------
If one of the true/false values of the VP_SELECT is undef can we ignore the mask and EVL and return the other operand? @simoll @frasercrmck
