Set by default when -d is given. 13 Also prints statistics on optimizations. 14 151) Show data structures after optimization but before intermediate 16 code generation. Also causes each optimizer data structure to 17 be printed as it is created (before optimization). 18 192) Show data structures prior to optimization. 20 213) Show data structures after loop optimization but before other 22 optimizations. 23 244) Show data structures after loop optimization and CSE but before 25 other optimizations. 26 276) Don't perform loop optimization. 28 297) Don't do copy propagation optimization. 30 318) Show data structures after fatal errors. 32 339) Show data structures after loop optimization, CSE and copy 34 propagation but before register optimization. 35 3610) Don't do register optimization. 37 3812) Print statistics on memory allocation (local version only). 39 4013) Don't do common subexpression elimination. 41 4214) Print history of stack temporary allocations (mkaltmpn()). 43
