摘　　要：IA-64体系结构使用软件流水提高程序的执行性能,但产生的二进制代码跟机器特性紧密相关,给代码跨平台移植造成了困难。该文针对IA-64体系结构下软件流水的特点,提出2种软件流水代码消除方法,它能够将软件流水代码转换成语义等价无硬件依赖的串行代码,实验验证了这2种方法的有效性。Software pipelining is used to improve the performance of programs in IA-64, but the codes generated are relevant to the hardware plat, which makes them difficult to be migrated between different platforms. This paper analyzes the software-pipelined mechanism of IA-64, and presents two methods to eliminate software pipelined codes from optimized IA-64 executables. These two methods can convert the software pipelined codes into semantically equivalent sequential counterparts without dependence on the hardware. Experiments verify the validity of the proposed methods.
