ABSTRACT:
A method and apparatus for reproduction of a legacy ISA application corresponding to a target ISA application state at an execution stop point are described. In one embodiment, the method includes the translation of a binary application generated for a legacy instruction set architecture (ISA) into a translated binary application for a target ISA. During translation, one or more instructions within the translated binary application are selected as commit point instructions. Once selected, the translated binary application is modified to store a source ISA application state corresponding to a target ISA application state prior to each selected commit point. In addition, the selected commit points indicate the location of the stored source ISA application state information.
