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:

3f67251e3d0ce61a0e7fc16de91de6fb49cad768 is the first bad commit commit 3f67251e3d0ce61a0e7fc16de91de6fb49cad768 Author: Christian König christian.koenig@amd.com Date: Sun Mar 10 14:33:29 2013 +0100

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

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