| Abstract: | Moped is a portable debugger that uses enhanced tracing facilities and backtracing to discover unusual or undesirable program behaviors. It is based upon two modules — Program Probes and Program History. Program Probes is a forward tracing utility which allows Moped to dynamically examine the execution of a program. Program History is a backtracing utility which allows Moped to study the executed section of a program. Together, Program Probes and Program History enable Moped to have more control over the behavior of a program than either one of them, and consequently to provide an easier path toward program debugging. Moped is written in Common LISP with no dependencies on details of the machine implementation. Therefore, it is easily portable to any Common LISP environment.This work supported in part by Hewlett-Packard Company, the National Science foundation Under Grant Number MCS81-21750 and the Defense Advanced Research Projects Agency under contract number DAAK11-84-K-0017. |
