Three of the 9 bits may also be used up for a 2nd Predicate (Twin Predication) leaving a mere 6 bits for qualifying registers. As can -be seen there is significant pressure on these (and all) SVP64 bits. +be seen there is significant pressure on these (and in fact all) SVP64 bits. In Power ISA v3.1 prefixing there are bits which describe and classify the prefix in a fashion that is independent of the suffix. MLSS for
