          Priority: medium
            Bug ID: 68901
          Keywords: regression
          Assignee: dri-devel@lists.freedesktop.org
           Summary: wine/3DMark2001: shader generation fails
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: gurketsky@googlemail.com
               URL: http://www.futuremark.com/support/downloads
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

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:
EE /mnt/raid0/software/mesa/git/src/gallium/drivers/r600/r600_shader.c:1886
r600_shader_from_tgsi - GPR limit exceeded - shader requires 129 registers

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