Ok, i expect the following methods on IntVector (and friends) to be made intrinsic at some point leveraging such instructions:

  public IntVector<S> shiftL(int s)

  public IntVector<S> shiftR(int s)

  public IntVector<S> aShiftR(int s)

Thanks!

No problem. I made a choice on the lane L/R direction based on ascending indexes rather than descending indexes, as you expected in your test case, that seems more intuitive in terms of order.
