--itrace::
Options for decoding instruction tracing data. The options are:
- i synthesize instructions events
- b synthesize branches events
- c synthesize branches events (calls only)
- r synthesize branches events (returns only)
- x synthesize transactions events
- e synthesize error events
- d create a debug log
- g synthesize a call chain (use with i or x)
-
- The default is all events i.e. the same as --itrace=ibxe
-
- In addition, the period (default 100000) for instructions events
- can be specified in units of:
-
- i instructions
- t ticks
- ms milliseconds
- us microseconds
- ns nanoseconds (default)
-
- Also the call chain size (default 16, max. 1024) for instructions or
- transactions events can be specified.
