In the process of trying to work around the spilling in the huge unigine soft shadowing shaders, I got to wondering if we couldn't just reduce the cost of spilling to the point of "I don't care". Notably, there is this nice message for doing unspills on gen7 where you don't need to set up the message beyond passing in g0.
It turns out to be a slight win. Unfortunately, the complementary spill message was a loss. You can find the code in this submission on gen7-scratch-read of my tree, and the code I'm not trying to push is on gen7-scratch-write. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
