Description gurketsky 2013-09-03 18:24:07 UTC 
When running 3DMark2001 in wine (1.7.1), the r600 gallium driver (on RV710) fails to generate some shaders. This is a regression:

    glsl_to_tgsi: allocate arrays separately v2
    
    Instead of allocating everything as temporaries, use the
    new array allocation functions.
    
    v2: fix bug in simplify_cmp, declare arrays on demand

The output when the shader generation fails is:

This is not a dupe of bug 62696 as the problem is still there with git version 6b5c802c30ada043ee31cc5e62249ff99bbc865f.
