Abstract
Method and apparatus for handling call stack unwinding when execution of an instrumented program is stopped in a first function of the instrumented program. When unwinding is initiated and a call to a second function of unwind software is made, the call to the second function is intercepted. The second function returns a reference to unwind information associated with the first function of the instrumented program. The unwind information includes references to locations of selected instructions in the function. If the first function of the instrumented program is instrumented with instrumentation code, then updated unwind information is created. The updated unwind information includes updated references to the locations of the selected instructions in the first function as offset by the instrumentation code. A reference to the updated unwind information is returned.
