ir_call doesn't implement equals, so it should always return 'not equals' via ir_instruction::equals. (ir_equals.cpp) This should prevent optimizations involving calls, right? -Jordan _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
