- Subject line almost says it all. Many modern processors have an
- instruction to swap the bytes in a word. Can one quantify the
- win of using this instruction vs. the equivalent sequence of
- instructions? How much silicon is needed? What applications
- win the most and how much? There must be *some* resaon why the
- RISC folks put it in, right?
