Subject: glsl: Consider ubo_load to be a horizontal operation.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3da789f1e9e3eb027bcfdb9d9170e7b37160b5b9;p=mesa.git

glsl: Consider ubo_load to be a horizontal operation.

Unclear to me whether it actually is a horizontal operation that cannot
be vectorized, but the fact that i965 generates the same code in either
case makes me less interested in finding out.
