Abstract
A system and method for instrumenting program instructions. A processing system includes a compiler and a profiler. The compiler is configured to notify the profiler of a compilation event corresponding to first program instructions. In response to detecting the event, the profiler is configured to intercept compilation of the first program instructions, determine whether an instrumented version of the first program instructions is currently available, instruct the compiler to compile the instrumented version of the first program instructions if available, and retrieve and instrument the first program instructions if not available. The profiler may maintain an instrumentation cache for storing instrumented versions of program instructions. The instrumentation cache may further include metadata which identifies portions of program code which have been instrumented and their location. The profiler may generally instrument program instructions once during the resident life of a corresponding application.
