Preparing a binary file for future instrumentation

摘要

Techniques for preparing a binary file for future instrumentation are provided. First object code and second object code are linked into a binary file. The first object code is created by compiling the source code of a computer program. The second object code comprises a first set of instrumentation code that is not referenced by any instructions in the object code of the computer program. The second object code stores commonly used instrumentation routines that are referenced by a second set of instrumentation code, which second set is inserted in the binary file when the binary file is subsequently instrumented.
