An Effective Reversible Debugger of Cross Platform Based on Virtualization

Cross platform debugging can make the software debugging and hardware platform developing work simultaneity in embedded system development, which accelerates the development lifecycle dramatically. Reverse execution can run program backward to historic points, may provide programmers with a useful approach of fast locating the cause of the program failure. In this paper we propose a reversible debugging framework for cross debugging and implement a prototype reversible debugger called Reversible Debugger for Cross Platform (RDXP) on X86/Linux platform based on PORD. The evaluation shows that RDXP provides an efficient and portable software debugging environment with reasonable speed and memory consumption.
