================
Comment at: llvm/lib/CodeGen/SelectionDAG/LegalizeVectorOps.cpp:1339
+
+  // X % Y -> X-X/Y*Y
+  SDValue Div = DAG.getNode(DivOpc, DL, VT, Dividend, Divisor, Mask, EVL);
----------------
I'd prefer something like the comment in DivRemPairs as it's a little clearer: `// X % Y --> X - ((X / Y) * Y).`
