        !             7: WHAT THE DEBUG FLAGS MEAN:
        !             8: 
        !             9: 0)     Dump core on fatal errors.  Set by default when -d is given.
        !            10:        Also prints statistics on optimizations.
        !            11: 
        !            12: 1)     Show data structures after optimization but before intermediate
        !            13:        code generation.  Also causes each optimizer data structure to
        !            14:        be printed as it is created (before optimization).
        !            15: 
        !            16: 2)     Show data structures prior to optimization.
        !            17: 
        !            18: 3)     Show data structures after loop optimization but before other
        !            19:        optimizations.
        !            20: 
        !            21: 4)     Show data structures after loop optimization and CSE but before
        !            22:        other optimizations.
        !            23: 
        !            24: 6)     Don't perform loop optimization.
        !            25: 
        !            26: 7)     Don't do copy propagation optimization.
        !            27: 
        !            28: 8)     Show data structures after fatal errors.
        !            29: 
        !            30: 9)     Show data structures after loop optimization, CSE and copy
        !            31:        propagation but before register optimization.
        !            32: 
        !            33: 10)    Don't do register optimization.
        !            34: 
        !            35: 12)    Print statistics on memory allocation (local version only).
        !            36: 
        !            37: 13)    Don't do common subexpression elimination.
        !            38: 
        !            39: 14)    Print history of stack temporary allocations (mkaltmpn()).
