Augmenting profile data with information gathered from a jit compiler

A computer program product for augmenting a first performance profile with data extracted from a Just-in-Time compiler, the Just-in-Time compiler compiling bytecodes into machine instructions and generating a performance profile, the bytecodes having an associated original call structure, the computer program product comprising:

• one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising instructions to:
• track “in-lining” optimizations performed by the Just-in-Time compiler compiling bytecodes into machine instructions;
• extract data associated with the tracked “in-lining” optimizations;
• store the extracted data in a second profile;
• and
• augment the first performance profile with the extracted data associated with the tracked “in-lining” optimizations, the extracted data comprising call paths corresponding to the original call structure associated with the bytecodes.

A computer system for augmenting a first performance profile with data extracted from a Just-in-Time compiler, the Just-in-Time compiler compiling bytecodes into machine instructions and generating a performance profile, the bytecodes having an associated original call structure, the computer system comprising:

• one or more computers;
• one or more computer readable storage media and program instructions stored on the one or more computer readable storage media for execution by at least one of the computers, the program instructions comprising instructions to:
• track “in-lining” optimizations performed by the Just-in-Time compiler compiling bytecodes into machine instructions;
• extract data associated with the tracked “in-lining” optimizations;
• store the extracted data in a second profile;
• and
• augment the first performance profile with the extracted data associated with the tracked “in-lining” optimizations, the extracted data comprising call paths corresponding to the original call structure associated with the bytecodes.
