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 the first 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 that collapse the associated original call structure as performed by a Just-in-Time compiler compiling bytecodes into machine instructions;
• extract data associated with the tracked “in-lining” optimizations that collapse the associated original call structure to provide extracted data that specifies functions within the associated original call structure that are collapsed by the tracked “in-lining” optimizations;
• store the extracted data that specifies functions within the associated original call structure that are collapsed by the tracked “in-lining” optimizations in a second performance profile;
• and
• augment the first performance profile with the extracted data that specifies functions within the associated original call structure that are collapsed by the tracked “in-lining” optimizations.

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 the first 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 one or more computers, the program instructions comprising instructions to:
• track “in-lining” optimizations that collapse the associated original call structure as performed by a Just-in-Time compiler compiling bytecodes into machine instructions;
• extract data associated with the tracked “in-lining” optimizations that collapse the associated original call structure to provide extracted data that specifies functions within the associated original call structure that are collapsed by the tracked “in-lining” optimizations;
• store the extracted data that specifies functions within the associated original call structure that are collapsed by the tracked “in-lining” optimizations in a second performance profile;
• and
• augment the first performance profile with the extracted data that specifies functions within the associated original call structure that are collapsed by the tracked “in-lining” optimizations.
