This patch series adds the needed support for this extension to the various parts of mesa to finally enable it for nvc0. Dave Airlie (1): glsl: lower cull_distance into cull_distance_mesa Tobias Klausmann (10): glapi: add GL_ARB_cull_distance mesa/main: add support for GL_ARB_cull_distance mesa/prog: Add varyings for arb_cull_distance mesa/st: add support for GL_ARB_cull_distance

Running Tomb Raider on Nouveau I found some flicker caused by ignoring precise modifiers on variables inside Nouveau. This series add precise/invariant handling to TGSI, which can be then used by drivers to disable certain unsafe optimisations which may otherwise alter calculations, which depend on having the same result across shaders. This series fixes this bug in Tomb Raider and one CTS test
