Selective branch-triggered trace generation apparatus and method

摘要

A method for selectively generating trace data is disclosed. Such a method includes executing a first module on a processor. The processor is operably coupled to a memory storing the first module and one or more branch modules. The method further includes detecting the execution of an instruction of the first module to execute a branch module. In response to detecting execution of the instruction, traces of branch modules subsequently executed by the processor are generated. Upon detecting a return of execution by the processor to the first module, the generation of traces is terminated and a trace report is generated. A corresponding apparatus and computer program product are also disclosed herein.
