Author: Vadim Girlin <[email protected]> Date: Sun May 5 06:01:20 2013 +0400 r600g/sb: fix kcache handling on r6xx Use the same limit for kcache constants in alu group on r6xx as on other chips (two const pairs). Relaxing this will require additional checks to make sure that all 4 consts in the group come from 2 kcache sets (clause limit), probably without noticeable improvements of shader performance.
