In this patch, I placed the LRW table in SPRG6 like before, but Kumar's code seems a little more compact, so I decided to use that one and fix it ;-)
It's a pity we seem to have one register short in the handler, so we need to load SPRN_SRR1 twice :-( Allthough the code-path now has 1 instruction less than my previous version most of the time (and 2 instructions more when way is not adjusted), benchmark results are barely affected by this: 1.- mplayer: Total time: 50.392s (50.316s previous patch) 2.- prboom timedemo: 20.1 fps (19.9 fps previous patch) 3.- memcpy speed: 179 MByte/s (180 Mbyte/s previous patch) Conclusion: difference not measurable between v4 and v5.
