Abstract

Subject program code is translated to target code in basic block units at run-time in a process wherein translation of basic blocks is interleaved with execution of those translations. A shared code cache mechanism is added to persistently store subject code translations, such that a translator may reuse translations that were generated and/or optimized by earlier translator instances.
