Compiler Performance Test and Analysis Based on Hardware Performance Counters
Yunlan Wang · Microelectronics & Computer · 2008
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.
