ABSTRACT:
In various embodiments of the present invention, debugging and program-behavior-analysis software can reconstruct register-based processor states for nested routine calls from the backing-store memory employed by a modern processor, and by processors of similar architectures, to automatically spill and restore register values via a register stack engine. Sufficient information resides in the backing-store memory to reconstruct the stack frames for all nested routines. However, reconstructing the stack frames from the backing-store memory depends on identifying stored register vales in the backing-store memory containing saved values of the previous-frame-marker application register. Various embodiments of the present invention employ a set of heuristic tests to evaluate stored values in the backing-store memory in order to identify those values corresponding to the stored contents of the previous-frame-marker application register.
