Since LLVM 3.5 will be released in August and my radeon patches adding ARB_draw_indirect depend on it, I will commit ARB_draw_indirect support for Gallium with softpipe and llvmpipe support earlier. My plan is for patches 3,4,5,6 to get committed in one week from now, or sooner if somebody reviews them.
