Subject: glsl: remove stage ref generation for transform feedback
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=42d283a0cc928a9e3ecddf1a90f9417ef1a34392;p=mesa.git

glsl: remove stage ref generation for transform feedback

Stage ref cannot be queried for transform feedback.

Also simplify the build_stageref function by passing the
correct mode for uniforms.
