Hi Phoebe, thank you for the feedbacks! By front end tests, do you mean `check-clang`? I updated the header files, but don't see failing tests in `check-clang`.

In addition, although the correct assembly is currently generated, is there a need to update `X86InstrSSE.td` given `vpdpb*` intrinsic argument types have been updated?
