Subject: i965: Fix GS push inputs with enhanced layouts.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c4be6e0b8d91746eccf334b9e20861af4036d06a;p=mesa.git

i965: Fix GS push inputs with enhanced layouts.

We weren't taking first_component into account when handling GS push
inputs.  We hardly ever push GS inputs, so this was not caught by
existing tests.  When I started using component qualifiers for the
gl_ClipDistance arrays, glsl-1.50-transform-feedback-type-and-size
started catching this.
