    I do not plan to implement registerized parameters in the near future,
    but I would not worry too much about efficiency.  DICE utilizes
    registers well, especially for low level subroutines (which is where
    the stack-args hit is most predominant).  In many such cases DICE is
    able to remove both the LINK/UNLK *and* both MOVEMs completely and use
    scratch registers as register variables.

    DICE will put as many argument vars and local vars into registers as
    possible without requiring the register keyword, just like Lattice and
    Aztec.  However, DICE is able to utilize more registers for register
    variables and generally makes better choices than either of the other
    two compilers.

    Needless to say, the performance gain you get from the above two items
    is much greater than you get with registerized parameters.

    Its messy.	It isn't just messy, it's *very* messy to implement.  I
    intend to keep DICE lean, mean... and bug free.

    The commercial version will have an 020 option to utilize MUL*.L and
    DIV*.L, bit field stuff, and the scaling modes for array indexing.
    Also, the commercial version will implement a couple of things I do not
    intend to put in the shareware version (floating point, bit fields,
    structural returns).
