Abstract

A cross-domain call jacketing system is provided in a computer system that embodies a first hardware (X) architecture to executing X-code in an X-domain and which simulates at least a second computer hardware (Y) architecture executing Y-code in a Y-domain. Cross-domain routine calls are jacketed for services in the cross-domain and for returns after the requested services have been performed. After jacketing X routine calls are transmitted for implementation by the simulating subsystem and Y calls are transmitted for implementation in the X domain. Call parameters are transformed from a representation that uses the call conventions of the calling domain to another representation that uses the call conventions of the called domain. Data in the mem-ory is generally globally accessible and the Y calls include data references that require memory access handling in the X domain.
A first jacketing table is provided for each executable routine in the X domain. A second jacketing table is provided for each ex-ecutable routine in the Y domain. A run-time jacketing routine is driven by the jacketing tables to drive the call parameter trans-formations needed to complete cross-domain calls.
