So as opposed to a unary operation which would look exactly the same apart from having a subcode? So what does gimple_assign_subcode () return for the GIMPLE_SINGLE_RHS case? Some random garbage? Seems I need to look at the tuples branch closer. Is there some overview documentation available that explains all the above? Thanks, Richard.
