Chop
     
        A {code generator} by Alan L. Wendt 
        for the {lcc} {C} compiler {front end}.  Version 0.6 is
        interfaced with Fraser and Hanson's {lcc} {front end}.  The
        result is a {C} compiler with good code selection but no
        {global optimisation}.  Chop can currently compile and run
        small test programs on the {VAX}.  The {NS32k} and {68000}
        code generators are being upgraded for lcc compatibility.
