I still think this is the basic problem. Unless you're on a really
weird architecture it really doesn't matter whether an
originally-written operation was signed or unsigned (with the
already-represented exception of sdiv/udiv). It's probably best to
take a step back and reassess this rather than ploughing on trying to
preserve long-departed information.
