Subject: i965: Do lowering of array indexing of a vector in the FS.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=df4d83dca4618eb7077637865763d3e9ab750d11;p=mesa.git

i965: Do lowering of array indexing of a vector in the FS.

Fixes a regression in ember since switching to the native FS backend,
and the new piglit tests glsl-fs-vec4-indexing-{2,3} for catching this.
