Possible fix
Can you try this patch? If it doesn't work can you get the debug output (RADEON_DEBUG=fp,vp) from when the test was passing?

Bug #: 46004
Summary: [r300g, bisected] piglit glsl-fs-discard-02 fails
Classification: Unclassified
Product: Mesa
Version: git
Platform: Other
OS/Version: All
Status: NEW
Keywords: regression
Severity: normal
Priority: medium
Component: Drivers/Gallium/r300
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: pavel.ondracka@email.cz
CC: vljn@ovi.com
Piglit glsl-fs-discard-02 fails with r300g since:
10937e651222501c0e9f4f44e6b842c261e2edfb is the first bad commit
commit 10937e651222501c0e9f4f44e6b842c261e2edfb
Author: Vincent Lejeune <vljn@ovi.com>
Date: Mon Jan 2 20:17:38 2012 +0100
glsl_to_tgsi: Use the GLSL compiler's new remove-output-reads pass.
The existing glsl_to_tgsi::remove_output_read pass did not work properly
when indirect addressing was involved; this commit replaces it with a
lowering pass that occurs before TGSI code generation.
Fixes varying-array related piglit tests.

Hi,
could you please provide the error output for this test, and the generated opcodes using RADEON_DEBUG=fp,vp envar ?
RADEON_DEBUG /path/to/piglit/bin/glsl-fs-discard-02
Regards,
Vincent

The patch doesn't help. Attaching a new log with 6d4b35c03619148cde89bc5eedaac3288001edd3 (right before the regression).

I'm guessing that this is a bug in the vertex shader. Does running with RADEON_NO_TCL=1 fix it?
