    .. code:: yoscrypt

        opt_share [selection]

    ::

        This pass identifies mutually exclusive cells of the same type that:
            (a) share an input signal,
            (b) drive the same $mux, $_MUX_, or $pmux multiplexing cell,

        allowing the cell to be merged and the multiplexer to be moved from
        multiplexing its output to multiplexing the non-shared input signals.
