You just reconstruct the jump log from the trace.   A register doesn't help you with any of this, you need an external interface.  If you're really (only) interested in looking at the 9k instruction cycles for interrupts, the better approach is gprof.

A trace log system is for reconstructing whole program flows, including things like stalls and cache misses...
