From c59802d3a147956d4f33586bb6221cd236987ee2 Mon Sep 17 00:00:00 2001 From: Chris Forbes Date: Sun, 18 May 2014 12:03:54 +1200 Subject: glsl: Convert uniform_block in lower_ubo_reference to ir_rvalue. Previously this was a block index with special semantics for -1. With ARB_gpu_shader5, this need not be a compile-time constant, so allow any rvalue here and convert the -1 to a NULL pointer.
