A method instruments a function in an executable file so that the instrumented function calls a generic preprocessor prior to execution of the body of the function. After the preprocessor modifies the original function's incoming parameters, the body of the function itself is executed. Finally, execution is directed to a generic postprocessor prior to returning from the function. The postprocessor modifies the outgoing parameters and return value. In one implementation, the parameters of an instrumented function are described and packaged into a descriptor data structure. The descriptor data structure is passed to the generic preprocessor and postprocessor. A generic processor uses the descriptor to select changed behaviors based on the calling context.

Method and apparatus for handling calls from relocated instrumented functions to functions that expect a return pointer value in an original address space. In various embodiments of the invention, instrumented versions of selected functions of an executable program are generated and stored in a relocation address space. When a function is called by a function in the relocation address space, a return pointer register stores a first return-pointer value that is an address in the relocation address space. The address in the original address space that corresponds (logically) to the first return-pointer value is identified as an original return-pointer value. The first return-pointer value is associated with the original return-pointer value, references to the original return-pointer value are substituted for references to the first return-pointer value, and the instruction at the address indicated by the original return-pointer value is replaced with a breakpoint. When the breakpoint is encountered upon return of control at the original return-pointer value, the first return-pointer value that is associated with the original return-pointer value is obtained, and control is transferred to the instruction at the address referenced by the first return-pointer value.
