Subject: glsl: Propagate invariant/precise after lowering const arrays.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=586f4a42e78f171c28c3ae37adb8671e09bd74b4;p=mesa.git

glsl: Propagate invariant/precise after lowering const arrays.

The new uniform may need precise as well.

Fixes copy propagation of constant array uniforms in Tomb Raider shaders.
