Hi, I have just published a branch with loop emulation for the r300 compiler here: http://cgit.freedesktop.org/~tstellar/mesa/
This adds support for unrolling of loops that have a constant number of iterations (e.g. for(i=0; i<10; i++) or for(i=10; i>0; i--) It only handles cases where the counter is either added to or subtracted from, like the examples above, but I think this covers a majority of loops. Loops that have an unknown number of iterations are unrolled as many times as possible without going over the instruction limit for the shader program. Right now, this is only enabled for fragment shaders, but I am working on enabling it for vertex shaders. Any comments/suggestions would be appreciated. Thanks. -Tom _______________________________________________ mesa-dev mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-dev
