I'm using a Radeon HD6950, it fails to build a shader when playing "War
Thunder", renders the login screen fine, starts to build shaders and then fails
and spams the following in the console:

EE r600_state_common.c:799 r600_shader_select - Failed to build shader variant
(type=1) -1
EE r600_shader.c:183 r600_pipe_shader_create - translation from TGSI failed !

same thing happens a lof of shaders from shadertoy.com.

OS: OpenSUSE Tumbleweed, glxinfo attached
