[Bug 29786] New: [Diablo II] Software Rasterizer broken after making OpenGL default renderer

http://bugs.winehq.org/show_bug.cgi?id=29786

Bug #: 29786
           Summary: [Diablo II] Software Rasterizer broken after making
                    OpenGL default renderer
           Product: Wine
           Version: unspecified
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

I use software rendering as workaround for bug #14348. I do this by:
LIBGL_ALWAYS_SOFTWARE=1 wine ~/.wine/drive_c/Diablo\ II/Game.exe

Unfortunately with new Wine releases software renderer doesn't work any more.
I've bisected this issue to:

94ae743ea668e49d40ae4e2dc5fe1f5d9be018cb is the first bad commit

It seems pretty likely that this is either a bug in swrast or an issue with
your setup. I tested this with the Diablo II demo on wine-1.4-rc3 and softpipe
from current (d2c54fb) Mesa and it renders fine for me, if a bit slow. For what
it's worth, r600g also works fine here. If this is about workarounds for bug
14348, I'd recommend the DRAW_USE_LLVM=0 environment variable mentioned there.
If that doesn't work either for some reason, you can still explicitly request
the behaviour from before 94ae743 by setting the DirectDrawRenderer registry
key. (See http://wiki.winehq.org/UsefulRegistryKeys for details.)

Henri Verbeet: can I ask what llvm version was used to compile your Mesa?

If you take a look at:
https://bugs.freedesktop.org/show_bug.cgi?id=41791
https://bugzilla.novell.com/show_bug.cgi?id=747333
you'll see I've discovered that downgrading llvm from 3.0 to 2.8 and
recompiling Mesa fixes this issue.

I guess it means it's Mesa or llvm issue, not Wine, is that right? Should we
close this bug report as NOTOURBUG/INVALID?

(In reply to comment #5)
> Henri Verbeet: can I ask what llvm version was used to compile your Mesa?

None. At least for the moment r600g doesn't use LLVM for anything, it's only
initialized by the common gallium code. I'd be much happier if it stayed that
way, but the are plans to use LLVM for the r600g shader compiler. As I'm sure
you've noticed by now, LLVM is just a huge pain to work with, or even link
against.

Yeah, this is INVALID.
