Reassigning to mesa-core since the issue could be in glsl-to-tgsi. In the meantime GLSL 1.30 has been enabled by default on r600g. Is this still an issue with current mesa from git? Vincent said on irc that this isn't an issue anymore. |

Hi, the following fragment shader : __ #version 130 uniform int mode; uniform vec3 red; uniform struct { vec3 green; vec3 blue; } teststruct; uniform vec3 testarray[3]; out vec3 fragColor; void main() { if (mode == 0) fragColor = red; if (mode == 1) fragColor = teststruct.green + teststruct.blue; if (mode == 2) { fragColor = vec3(0.); for(int i = 0; i < 3; i++) fragColor += testarray[i]; } } __ is lowered to : __ FRAG PROPERTY FS_COLOR0_WRITES_ALL_CBUFS 1 DCL IN[0], COLOR, LINEAR DCL OUT[0], COLOR 0: MOV OUT[0], IN[0] 1: END __ using mesa from git, swrast, and setting glsl supported version to 130 in st_extensions.c ; glsl_compiler --dump-lir seems correct, so it might be an issue with glsl-to-tgsi.
