新版本gem5的splash2 run.py修改版本

在新版本gem5中，各种类属性有了改动，然而对应的config/splash2/run.py脚本并未做修改，因此直接运行时会报错（如果没改过，碰到的第一个错应该就是class L1没有latency属性了）。我把run.py和config/example/se.py做了对照，一个个修改，下面的run.py终于能直接运行了。我把其中class L1 L2删了，直接用Caches.py里面的L1Cache L2Cache替代，其他杂七杂八什么clock voltage也是模仿se.py进行修改。改完的经验是，如果你不清楚每个类具体是什么，不妨在脚本里插入print type() dir()什么的，可以迅速定位到其类型，然后看新版本属性有了什么改动，还有grep命令也是在目录中定位文件的利器。
