12.3.2. Trace generation

The PFT architecture assumes that the trace tools can access a copy of the code being traced. For this reason, the PTM generates trace only at certain points in program execution, called waypoints. This reduces the amount of trace data generated by the PTM compared to the ETM protocol. Waypoints are changes in the program flow or events, such as an exception. The trace tools use waypoints to follow the flow of program execution. For full reconstruction of the program flow, the PTM traces:

You can also configure the PTM to trace:
