1 | i synthesize instructions events |
| 2 | b synthesize branches events | |
| 3 | c synthesize branches events (calls only) | |
| 4 | r synthesize branches events (returns only) | |
| 5 | x synthesize transactions events | |
| 6 | e synthesize error events | |
| 7 | d create a debug log | |
| 8 | g synthesize a call chain (use with i or x) | |
| 601897b5 | 9 | l synthesize last branch entries (use with i or x) |
| d1706b39 | 10 | s skip initial number of events |
| 60b88d87 AH |
11 | |
| 12 | The default is all events i.e. the same as --itrace=ibxe | |
| 13 | ||
| 14 | In addition, the period (default 100000) for instructions events | |
| 15 | can be specified in units of: | |
| 16 | ||
| 17 | i instructions | |
| 18 | t ticks | |
| 19 | ms milliseconds | |
| 20 | us microseconds | |
| 21 | ns nanoseconds (default) | |
| 22 | ||
| 23 | Also the call chain size (default 16, max. 1024) for instructions or | |
| 24 | transactions events can be specified. | |
| 601897b5 AH |
25 | |
| 26 | Also the number of last branch entries (default 64, max. 1024) for | |
| 27 | instructions or transactions events can be specified. | |
| d1706b39 AK |
28 | |
| 29 | It is also possible to skip events generated (instructions, branches, transactions) | |
| 30 | at the beginning. This is useful to ignore initialization code. | |
| 31 | ||
| 32 | --itrace=i0nss1000000 | |
| 33 | ||
| 34 | skips the first million instructions. |
