From 44a117ab9ac7e18ffddf4d59ae35fe2c266efc1d Mon Sep 17 00:00:00 2001 From: Vadim Girlin Date: Sat, 25 May 2013 22:56:53 +0400 Subject: r600g/sb: fix handling of preloaded inputs for compute shaders For compute shaders we need to let the backend know that GPRs 0 and 1 are preloaded with some compute-specific input values, otherwise any use of these regs without previous definition is considered as undefined value and usually is simply replaced with 0.
