================
Comment at: llvm/lib/Target/X86/X86ISelLowering.cpp:9253
+      // TODO, there may be some general way to know if a SDNode can
+      // be foled. We now only know whether an MI is foldable.
+      if (Opc == X86ISD::VPDPBUSD && U->getOperand(2).getNode() != N)
----------------
foled -> folded
