From 300315fe69ba275dda8a4786783c2bdd007d0758 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 23 Jul 2012 11:05:11 -0700 Subject: [PATCH] glsl: Fix glGetActiveUniformsiv(GL_UNIFORM_BLOCK_INDEX). Previously, we were returning the index into the UniformBlocks of one of the linked shaders, when it's supposed to be the program global index. Fixes piglit getactiveuniformsiv-uniform_block_index.
