This patchset optimizes the "swap bytes within words" instructions on the arm, cris and mips targets. It all started with the patchset from Philippe Mathieu-Daudé optimizing TCG code by using the extract op. Looking at the patch I have found that the aarch64 rev16 function can be optimized even more. Richard Henderson then suggested an even more optimized version.
