概述
最近在研究gem5，nvmain, 并将nvmain集成到gem5里面，然后用基准测试spec cpu2006进行测试。之前一直找不到基准测包，现在终于找到了，在此写下实验过程。
我的系统是ubuntu,spec cpu 2006是cpu2006-1.2.iso镜像。
1. 解压cpu2006-1.2.iso
2 .安装spec cpu 2006
执行下面的命令：
./install.sh -d /home/jyf/download/speccpu2006注意：/home/jyf/download/speccpu2006 是我电脑上的安装路径，可自定义。
3.运行shrc脚本
source shrc4.修改配置文件
将config目录下的 Example-linux64-amd64-gcc41.cfg配置文件复制下，命名为gcc41.cfg，由于gem5运行spec需要静态可执行文件，所以将gcc41.cfg文件修改：
将
COPTIMIZE = -O2
CXXOPTIMIZE = -O2
FOPTIMIZE = -O2 改为
COPTIMIZE = -O2 -static
CXXOPTIMIZE = -O2 -static
FOPTIMIZE = -O2 -static5.编译其中一个benchmark(这里是编译的gcc)
runspec –config=gcc41.cfg –action=build –tune=base gcc
若出现runspec找不到命令时，需要回退到spec的安装目录，即输入命令
.空格./shrc注意：编译成功后会在bencuspec下的cpu2006下的403.gcc包里产生exe和build两个文件。
6.在gem5中用cpu 2006进行基准测试：
./build/X86/gem5.opt ./configs/example/se.py -c ../../speccpu2006/benchspec/CPU2006/450.soplex/exe/soplex_base.gcc41-64bit -o ../../speccpu2006/benchspec/CPU2006/450.soplex/data/test/input/test.mps 注意：
540.sople可以运行，运行结果在/home/jyf/download/gem_nvmain/gem5-master/m5out/stats.txt，但还是会提示：info: Increasing stack size by one page.
运行结果：

---------- End Simulation Statistics ----------这里还存在一个问题：info: Increasing stack size by one page.修改了gem5里一些配置参数，还是不行。
参考博客：
1.gme5集成nvmain
2.报错：Increasing stack size by one page
