Subject: glsl: Mark the array access for whole-array comparisons.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b4f585665c31b1f80d909e38b3b2a9fab0c03076;p=mesa.git

glsl: Mark the array access for whole-array comparisons.

By not doing so, the uniform contents of
glsl-uniform-non-uniform-array-compare.shader_test was getting thrown
out since nobody was recorded as dereferencing the array.
