摘　　要：Itanium 2处理器提供的性能监控单元实现了在程序运行过程中捕捉微结构事件的功能.利用GNU Gcc、Intel Icc和HP-Opencc编译器的不同优化选项编译并运行SPEC2006基准程序.通过CPU硬件计数器(HPCs)采集的性能数据,了解特定程序特征,分析比较编译器性能差异,对HP-Opencc编译器的性能优化给出相关参考数据.实验表明HP-Opencc编译器的的分支预测优化技术可再改进.Itanium 2 processors are providing hardware support that help to capture microarchitectural events that occur during the running of a program. Make use of GNU Gcc, Intel Icc and HP-Openc compilers＇different compiler optimization, compiler and run the SPEC2006 benchmark, based on the sampling value of hardware performance counters, analysis particular program＇s feature and performance discrepancy of compilers, provide reference datas to HP-Opencc＇s compiler optimize. The experiment indicates that HP-Opencc compiler＇ s branch prediction optimization techniques may further improve.
