Summary: [r300g] Unknown opcode DDX with RV350 Product: Mesa Version: git Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: rankincj@googlemail.com
Output from piglit's glsl-derivs program:
r300 FP: Compiler Error: r300_fragprog_emit.c::translate_rgb_opcode(): translate_rgb_opcode: Unknown opcode DDX Using a dummy shader instead. If there's an 'unknown opcode' message, please file a bug report and attach this log. Probe at (205,125) Expected: 0.800000 0.400000 0.000000 Observed: 0.000000 0.000000 0.000000
And similarly for glsl-deriv-varyings.

--- Comment #1 from Marek Olšák maraeo@gmail.com 2010-07-13 13:45:30 PDT --- Unfortunately, this is a hardware limitation and fixing it is impossible. If you really want this opcode, I recommend using a software rasterizer like llvmpipe. Really, there is nothing we can do.

--- Comment #2 from Roland Scheidegger sroland@vmware.com 2010-07-13 18:53:19 PDT --- I dunno, maybe should output a bit different message for opcodes known to be impossible to implement? That would make it more obvious it's really a hardware limitation and not a driver bug.
