摘要: 在程序实际执行中,Profiling技术能为编译器提供准确的轮廓信息。编译优化借助这种轮廓信息,可在优化时进行取舍,提高生成代码性能。该文介绍了在龙芯/ORC编译器中edge profiling的技术,给出了在edge profiling辅助下CPU2000性能测试结果。

关键词: 轮廓信息, edge profiling, 龙芯/ORC编译器

Abstract: A compiler can get accurate execution profile information about the program through profiling. It takes advantage of this information to aid trade-off making in various optimizations and improves the performance of the final code. This paper introduces the edge profiling technology in Godson/ORC compiler, gives the performance test report of CPU2000 with edge profiling enabled.

Key words: profile information, edge profiling, godson/ORC compiler
