Hi, I have just pushed a branching adding support for presubtract sources to my personal repo. The branch contains peephole optimizations for all the presubtract operations except for 1 - 2 * src0. I've tested this branch on an RV370 and an RV515 and both match the piglit results from master.
The branch name is presub-rebase-v2 and you can check it out from here: git://anongit.freedesktop.org/~tstellar/mesa The changes in the branch touch almost every part of the compiler, so I'll wait a few days to push this to give people a chance to comment. I haven't done a lot of performance testing on this branch yet, so I'm not sure what the performance impact will be. I'm hoping at the very least this will help fix some of the "too many instructions" bugs. -Tom _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
