           Summary: E-350 misprocesses shader
           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)

Screenshot of the failure

If you pull from my e350bug branch (
http://cgit.freedesktop.org/~cand/mesa/log/?h=e350bug ) and execute
"pp_jimenezmlaa=8 glxgears", you should see a fully white window. What actually
happens on the E-350 is attached.


The gist is "a long shader; output = white;", which should always create white,
since the shader has no kilp/discard. While this would rarely happen in
practise (the glsl compiler would eliminate dead code), this is a clear bug,
and I believe this is causing me other grief.

While the branch is based on ~4 weeks old master, the bug is present when
merged with today's master.

The kernel I'm on is 3.0.1.
