From ddca4592a7fa08cc294403d221a5f329ee4991e9 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 22 Aug 2011 11:48:04 -0700 Subject: [PATCH] i965/vs: Don't lower uniform array indexing. This avoids the massive conditional move array access, and brings code generation quality for the new VS backend into the realm of efficiency of the old backend (roughly 20% more instructions generated than before across shader-db, instead of assertion failing for generating over 10,000 instructions on many shaders!).
