                      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()).
