[Qemu-devel] [PATCH 0/4] target/arm, cris, mips: optimize "swap bytes within words"

[Aurelien Jarno]

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.

Aurelien Jarno (4):
  target/arm: optimize aarch32 rev16
  target/arm: simplify and optimize aarch64 rev16
  target/cris: optimize swap
  target/mips: optimize WSBH, DSBH and DSHD
