Process and system for merging trace data for primarily interpreted methods

An apparatus for profiling an instrumented program executing in a data processing system, the apparatus comprising:

• first recording means for recording trace data in response to an occurrence of a selected event within the instrumented program;
• detecting means for detecting an occurrence of a selected interrupt;
• identifying means for identifying a call stack associated with the instrumented program in response to the detection of the selected interrupt;
• examining means for examining the call stack to identify each routine that is currently executing in association with the instrumented program;
• and
• second recording means for recording additional trace data which includes an indication of each currently executing routine.

A computer program product on a computer readable medium for use in a data processing system for profiling an executing program, the computer program product comprising:

• first instructions for recording trace data in response to an occurrence of a selected event within the instrumented program;
• second instructions for detecting an occurrence of a selected interrupt;
• third instructions for identifying a call stack associated with the instrumented program in response to the detection of the selected interrupt;
• fourth instructions for examining the call stack to identify each routine that is currently executing in association with the instrumented program;
• and
• fifth instructions for recording additional trace data which includes an indication of each currently executing routine.

A data processing system comprising:

• a bus system;
• a communications unit connected to the bus system;.
• a memory connected to the bus system, wherein the memory includes a set of instructions;
• and
• a processing unit connected to the bus system, wherein the processing unit executes the set of instructions to record trace data in response to an occurrence of a selected event within an instrumented program;
• detect an occurrence of a selected interrupt;
• identify a call stack associated with the program in response to the detection of the selected interrupt;
• examine the call stack to identify each routine that is currently executing in association with the program;
• and record additional trace data which includes an indication of each currently executing routine.
