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).

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

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

    st/mesa: convert ir_triop_lrp to TGSI_OPCODE_LRP
    
    AFAICT, all gallium drivers implement TGSI_OPCODE_LRP.
    Tested with softpipe, llvmpipe, svga drivers.

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.
