[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:2634
+      (N1.getOpcode() == ISD::TRUNCATE) &&
+      (N1.getOperand(0).getOpcode() == ISD::VSCALE)) {
+    EVT VSVT = N1.getOperand(0).getValueType();
----------------
Do you need to check that both vscales have the same types?
