Can you add a couple of comments:
/* Check for transform feedback varyings specified via the API */
shader->info.has_transform_feedback_varyings =
shader_prog->TransformFeedback.NumVarying > 0;
/* Check for transform feedback varyings specified in Shader */
+ if (shader_prog->last_vert_prog)
+ shader->info.has_transform_feedback_varyings |=
+ shader_prog->last_vert_prog->sh.LinkedTransformFeedback->NumVarying >
0;
return shader;
}
Otherwise:
