From 09e2df5961cfe04925bdd820e6ea59af3ba783f6 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 30 Aug 2013 10:45:00 -0700 Subject: [PATCH] i965/vs: Fix regression on pre-gen6 with no VS uniforms in use. df06745c5adb524e15d157f976c08f1718f08efa made it so that we didn't allocate extra uniform space for unused clip planes, which also incidentally made us not allocate any space at all, which we were relying on for this no-uniforms case. Instead of putting the knowledge of this special HW exception into the thing that normally preallocates prog_data for us, just allocate it here.
