Ralf Meyer (another Laurentian prof) did some quick and dirty experimentation with preliminary versions of bit-twiddling minmods and found that on PowerPC chips it made a big difference. Not on Intel. Not really surprising: Avoiding branches like the plague is more relevant to PowerPC/cell than Intel. In GEGL (production) code? Not sure.
