[PATCH] D60150: [DAGCombiner][x86] scalarize splatted vector FP ops

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:18133
+      // splat (scalar_bo (extelt L, Index), (extelt R, Index))
+      SDValue L = N0.getOperand(0), R = N0.getOperand(1);
+      SDLoc DL(N);
----------------
Should we assert that the splat index is coming from N0?
