code compression

This paper discusses the target of loops optimization and various methods of program transformation which can significantly reduce the access time to subscripted variables , diminish some types of dependence , increase the " depth " of software pipelining , and merge some iterations of loops in order to make code compaction easier
程序变换可大大减少下标变数的访问时间；消除某些类型的相关，提高软件流水的“深度” ；合并多个循环，有利于进行代码压缩。
