ABSTRACT:
A method is disclosed for instructing a computing system to unwind a program call stack that lacks explicit Stack Frame Backchain Pointers, including finding the called function's entry point, determining the return point in the calling function, placing a NOP instruction at the return point that contains embedded information about what type of call was used, and backing up in storage by an amount determined by using the address of the called function's entry point to locate the static data item containing the called function's DSA size.
