    // for example: `Rdd=memd(gp+#u16:3)` can be extended. if u16 is `0...1111`, where the low
    // three bits are all set, the address used for gp-relative addressing would be `1111000`. as
    // an extended constant, would this also be `1111000` and illegal for extension as bits other
    // than the low six are set? or is this `000111` with an unaligned address but otherwise
    // extended and legal for execution?
    //
    // i am going to assume that the shifted immediate is used.
