RADEON_DEBUG=fp,vp

In Anno1701, some models are red, however they are rendered with correct colors
when RADEON_DEBUG=noopt is used (or with glsl disabled in Wine).

Apitrace here http://pavel.ondracka.cz/Anno1701.trace (renders fine with
proprietary NVIDIA drivers).

Wine: 1.5.23
GPU: RV530
Mesa: f1ab67c13ab97f19c08d99c6ba101edc7d7b80e6
Kernel: 3.7.3-101.fc17.i686

Could you post a dump with RADEON_DEBUG=noopt,vp,fp

RADEON_DEBUG=noopt,fp,vp output

New log attached. However there is something bad going on. There are two bugs
affecting this game. This one and bug 60965, however when I reported them, this
bug used to disappeared with RADEON_DEBUG=noopt and bug 60965 didn't. Now when
I use RADEON_DEBUG=noopt, the corruption from bug 60965 is much worse and is
all over the place. The change did happened with 
f6c061261885fed0c83c437e9459ba79618f1b3a is the first bad commit

    st/mesa: convert ir_triop_lrp to TGSI_OPCODE_LRP

    AFAICT, all gallium drivers implement TGSI_OPCODE_LRP.
    Tested with softpipe, llvmpipe, svga drivers.

    Reviewed-by: Matt Turner <mattst88@gmail.com>

without RADEON_DEBUG=noopt the corruption is still the same, so my guess is
that r300 compiler somehow doesn't like TGSI_OPCODE_LRP, optimizes is away a
little bit, but not completely.
