From 122c3b9486d3dbf8cb6b796c9a25f43817f006d3 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 11 Feb 2014 09:41:44 +1000 Subject: [PATCH] glsl/i965: move lower_offset_array up to GLSL compiler level. This lowering pass will be useful for gallium drivers as well, in order to support the GL TG4 oddity that is textureGatherOffsets.
