Author: Marek Olšák <[email protected]> Date: Sat Jul 25 12:01:07 2015 +0200 gallium/radeon: re-enable unsafe math for graphics shaders This reverts commit 4db985a5fa9ea985616a726b1770727309502d81. The grass no longer disappears, which was the reason the commit was reverted. This might affect tessellation. We'll see.
