Software debugging system and method especially adapted for code debugging within a multi-architecture environment

摘要

In a computer system that embodies a first hardware (X) architecture and includes a memory system and at least one simulator for a second (Y) architecture and a system for executing and debugging multiple codes having an environment manager that handles cross-domain calls, a debugging system and method are provided for debugging code in each domain as part of said multi-code executing and debugging system in a multi-architecture environment. In response to calls for debugging from either the X domain or the Y domain, commands are generated for controlling operations in both domains. User generated RUN and STEP commands control the machine execution state in the domain where debugging is performed. General support commands and debug operations support commands including EXAMINE, DEPOSIT, SET BREAKPOINT and CANCEL BREAKPOINT commands which are implemented differently for the different domains may also be user generated for controlling debugging.
