Systems and methods for selectively instrumenting a program according to performance characteristics

A non-transitory computer-readable medium storing instructions for selectively instrumenting a program and that when executed by one or more processors cause the one or more processors to:

• analyze the program to generate overhead scores associated with segments of instrumentation within separate functions of the program, wherein the instrumentation is combined with source code to provide functionality in addition to a base functionality of the program;
• and
• selectively modify the segments in the source code of the program for the separate functions according to whether the overhead scores for respective ones of the segments satisfies an instrumentation threshold associated with respective ones of the separate functions,
• wherein the instructions to generate the overhead scores include instructions to calculate the overhead scores for the respective ones of the segments associated with the separate functions as a ratio of a program count and an instrumentation count relative to a runtime coverage for the separate functions.

A method of selectively instrumenting a program, comprising:

• in response to compiling the program from source code into machine code, analyzing the program to generate overhead scores associated with segments of instrumentation within separate functions of the program, wherein the instrumentation is combined with the source code to provide functionality in addition to a base functionality of the program;
• and
• selectively modifying the segments in the source code for the separate functions according to whether the overhead scores for respective ones of the segments satisfy an instrumentation threshold associated with respective ones of the separate functions,
• wherein generating the overhead scores includes calculating the overhead scores for the respective ones of the segments associated with the separate functions as a ratio of a program count and an instrumentation count relative to a runtime coverage for the respective ones of the segments.
