开放世界逃逸分析算法中的优化和反优化问题

his paper introduced the optimization and deoptimization technologies for Escape Analysis in open world. These technologies are used in a novel Escape Analysis framework that has been implemented in Open Runtime Platform, Intel's open-source Java Virtual Machine. We introduced the optimization technologies for synchronization removal and object stack allocation, as well as the runtime deoptimization and compensation work. The deoptimization and compensation technologies are crucial for a practical Escape Analysis in open world. We evaluated the runtime efficiency of the deoptimization and compensation work on benchmarks like SPECjbb2000 and SPECjvm98.
