+    // Otherrwise promote the input to i32 first.
     setOperationPromotedToType(ISD::UINT_TO_FP, MVT::v4i8, MVT::v4i32);

Thanks, the comment change is gone after moving to the existing if/else.

     if (Subtarget->hasFullFP16()) {
       setOperationAction(ISD::SINT_TO_FP, MVT::v4i16, Custom);
       setOperationAction(ISD::UINT_TO_FP, MVT::v4i16, Custom);
