| description | In one or more embodiments, a data processing system can include at least one core capable of executing instructions of an instruction set architecture and a trace unit coupled to the at least one core. A call to a subroutine can be detected, and in response, a program trace correlation (PTC) message can be generated and sent to a trace port. Data associated with an execution of the subroutine and/or performance of the data processing system can be sampled and sent to the trace port. A return from the subroutine can be detected, and in response, a trace message can be generated and sent to the trace port. The PTC message and the trace message can be correlated, and the correlation of the PTC message and the trace message can be used to determine a boundary for the subroutine and/or the sampled data associated with the execution of the subroutine. |
