From c88385603ae8d983314b736a9459bbf7d002cf11 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 19 Nov 2014 10:17:35 +1000 Subject: [PATCH] r600g: do all CUBE ALU operations before gradient texture operations (v2.1) This moves all the CUBE section above the gradients section, so that the gradient emission happens on one block which is what sb/hardware expect. v2: avoid changes to bytecode by using spare temps v2.1: shame gcc, oh the shame.
