Subject: i965: Fix type of gl_FragData[] dereference for FB write.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2927b6c21202fd0f9a661665e0093e7193c5df6e;p=mesa.git

i965: Fix type of gl_FragData[] dereference for FB write.

Fixes glsl-fs-fragdata-1, and hopefully Eve Online where I noticed
this bug in the generated shader.  Bug #31952.
