| 25 // RedefineClasses tracing support via the TraceRedefineClasses | |
| 26 // option. A bit is assigned to each group of trace messages. | |
| 27 // Groups of messages are individually selectable. We have to use | |
| 28 // decimal values on the command line since the command option | |
| 29 // parsing logic doesn't like non-decimal numerics. The HEX values | |
| 30 // are used in the actual RC_TRACE() calls for sanity. To achieve | |
| 31 // the old cumulative behavior, pick the level after the one in | |
| 32 // which you are interested and subtract one, e.g., 33554431 will | |
| 33 // print every tracing message. | |
| 34 // | |
| 35 // 0x00000000 | 0 - default; no tracing messages | |
| 36 // 0x00000001 | 1 - name each target class before loading, after | |
| 37 // loading and after redefinition is completed | |
| 38 // 0x00000002 | 2 - print info if parsing, linking or | |
| 39 // verification throws an exception | |
