It is assumed that AUX area decoding will synthesize events for consumption by other tools. At this time, the main use of AUX area tracing will be to capture instruction trace (aka processor trace) data. The nature of instruction tracing suggests the initial inclusion of options for "instructions" and "branches" events, but more could be added as needed.
