Hmm, uiCA results: xlatb: https://bit.ly/3cyBNN5 https://bit.ly/3cyBNN5 sequence: https://bit.ly/3nCmVTX https://bit.ly/3nCmVTX xlatb is looking better here. There are also some front end concerns that may favor xlatb, in particular if it's friendlier to the decoder. xlat is also fewer muops, taking less of the muop cache once decoded.
