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).
