           Summary: [r300g] Too many ALU instructions
           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: isukin.intelliware@gmail.com


"Toyball" standard demo is not working now (it was working with older versions
of Mesa). Output is:
r300 FP: Compiler Error:
r300_fragprog_emit.c::emit_alu(): Too many ALU instructions
Using a dummy shader instead.

Can you file a new bug.  This is a different problem.

Yes, it's in 7.10.

Note that this is not a bug, it's a hardware limitation. Sometimes we can
improve the compiler so that it generates a little less instructions, but that
only applies to shaders the size of which is very close to the hardware limit.
Too long shaders are simply NOT supported by hardware. Period.

Please set the environment variable RADEON_DEBUG=fp and attach the output
gnome-shell will generate (in a new bug).
