Patent
CA 2081977
2081977 9215961 PCTABS00016 A cross-domain call detection system is provided in a computer system that embodies a first hardware (X) architecture and includes a memory system and a system for executing and debugging multiple codes having a subsystem for simulating at least a second computer hardware (Y) architecture on the computer system and a jacketing subsystem for handling cross-domain calls. An X code and a Y code are stored in the memory system. The X code is executed on the X hardware and the Y code is executed by a simulator on the X hardware. Stub routines and an instruction interrupt fault mechanism are provided for detecting calls from executing X code routines for services in the Y domain. An address range detector and a common stub routine are provided for detecting calls from executing Y code routines for services in the X domain. The detected cross-domain calls are passed for processing by the jacketing subsystem.
