Author: Kenneth Graunke <[email protected]> Date: Mon Oct 17 14:23:10 2016 -0700 i965: Use NIR-based clip/cull lowering for OpenGL as well. The old approach works fine, and this approach isn't necessarily better. But it at least has the advantage that Vulkan and GL use the same approach. I originally wrote it to gain additional testing for the new paths. shader-db statistics show 0 instruction count changes.
