Abstract:
A program is executed on a processor to produce execution events. The execution events are traced using a first trace mode during a first portion of the program execution, wherein a portion of trace information for the execution events is omitted from a trace report while tracing in the first trace mode. The mode of tracing is dynamically changed to a second trace mode in response to an event trigger, such that all execution events that occur during the change of mode are captured. Execution events are traced during a second portion of the program execution using the second trace mode, wherein additional trace information for the execution events is included in the trace report while tracing in the second trace mode. The trace mode may be dynamically switched between the two trace modes during execution of the program.
