Currently, if you try to use ctrl-c while python code is running nothing happens. This is not ideal. This change enables users to use ctrl-c while python is running (e.g., when a large disk image is downloading). To do this, we moved the `initSignals` function in gem5 from `main` to the simulate loop. Thus, every time the simulate loop starts (i.e., is called from python) gem5 will install its signal handlers. Also, when the control is returned to python, we put python's default SIGINT handler back. Change-Id: I14490e48d931eb316e8c641217bf8d8ddaa340ed Signed-off-by: Jason Lowe-Power <jason@lowepower.com>
