| 88 | gen_exe_tbl(), for SS_Instr and all its children, produces entries |
| 89 | for various execution tables, e.g. the idx, run, and trc |
| 90 | exe_tables. Each entry corresponds to a decoded instruction |
| 91 | action -- a function that simulates the instruction's behavior. |
| 92 | |
| 93 | gen_exe_tbl() writes its output to 'file'. |
| 94 | |
| 95 | Which kind of entry is controlled by 'mode', which can be either |
| 96 | 'idx', 'run', or 'trc', for index, fast (or run) mode, or |
| 97 | tracing/ras mode. 'idx' populates the ExeIdx enum, 'run' fills |
| 98 | run_exe_table[], and 'trc' fills trc_exe_table[]. gen_exe_tbl() |
| 99 | guarantees that the order and size of these tables will all match |
| 100 | so that a ExeIdx enum can be used to index either exe table and |
| 101 | the corresponding table entries will refer to the same instruction |
| 102 | behavior. |
| 103 | |
| 104 | Note that at each level in the class hierarchy, gen_exe_tbl() |
| 105 | produces *all* the table entries for the class' instance. This |
| 106 | may involve some list traversal, multiple entry generation, or |
| 107 | emitting nothing -- the behavior is ad hoc. |
