| 摘 要： | 寄存器分配技术是编译器最为关键的优化技术之一.反馈式编译优化是一种基于程序当前和以前运行时的趋势来改变程序以后执行动作的技术,它能够提供给寄存器分配一些有用的优化信息.在分析Open64编译器反馈式编译优化技术的基础上,基于ALPHA结构实现和扩展了反馈式编译优化在寄存器分配中的应用,获得了较好的优化性能.

| Abstract: | Register allocation has become one of the most important optimization techniques of complier.Feedback-directed compiling optimization is a technique which can alter later executing operation of programs based on current and previous program running trend,and it can provide some useful information to register allocation.Feedback-directed compiling optimization technique of Open64 complier is analyzed,on that basis the ALPHA architecture is used to have achieved and extended the application of the technique i... |
