System for executing and debugging multiple codes in a multi- architecture environment using jacketing means for jacketing the cross- domain calls

摘要

A system is provided for executing and debugging multiple codes in a multi-architecture environment that includes a real X architecture (domain) and a simulated (Y) architecture (domain). The multiple code executing and debugging system comprises an X computer system having a memory with stored X and Y code and having the X architecture embodied therein.PPA detector is provided to detect calls from executing code in either domain for cross-domain services including execution of cross-domain routines. A jacketing system jackets cross- domain routine calls to interface the calling conventions of the calling and the called routines.
