Subject: i965/vs: Fix builtin uniform setup.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fea7d34b3545878ce00914f388e1eeebf55f7748;p=mesa.git

i965/vs: Fix builtin uniform setup.

I want to intelligently pack them at some point, but for now we have
the params set up in groups of 4.  Fixes glsl-vs-normalscale.
