[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added inline comments.


================
Comment at: llvm/lib/Target/X86/X86ISelDAGToDAG.cpp:3576
+    SDValue BitWidthC =
+        CurDAG->getConstant(NVT.getScalarSizeInBits(), DL, MVT::i32);
+    insertDAGNode(*CurDAG, SDValue(Node, 0), BitWidthC);
