Abstract
A system and method for non-sequential program execution in an incompletely assembled runtime environment. In a program debugging context, a primary advantage is that neither a fully linked executable nor a complete code base is required to execute the program. As well, it is not necessary to begin execution at the traditional program entry point. Six key methods are described. Virtual execution initialization logic involves establishing the runtime environment within the context of the first statement of execution. Statement execution logic concerns execution of a program statement and a technique by which the runtime copes with incomplete information. Reset execution point logic allows the user to randomly reposition the current execution point within a program without violating the runtime environment. Finally, methods for adding and deleting callers into/from the runtime stack are outlined. Extensions for multi-process and thread support are outlined as well as the incorporation of standard and application libraries into the execution model.
