Thanks Nate, that's very useful information.
I might need to explain a little more detail about what I'm trying to
achieve.
I have a program that may cause a run-time error (e.g. divide by zero).
If I run this outside of the simulator, I can check the return code to
determine if an error occurred.
However, when the division by zero occurs, I get the following on the
simulator output:
warn: ignoring syscall kill(100, 8, ...)
So I guess it's ignoring the division by zero.
I guess what I would need is to be able to prevent the simulator from
ignoring this. Any ideas?
Thanks
David

The exit system call is handled, so you can hack into the exitFunc()
function in src/sim/syscall_emul.cc if you want to do it in C++. In
python, the simulate function returns an ExitEvent object. Right now,
you can see that we generally call only getCause() on that object.
There is also a getCode() function that you can call to get the exit
code. If the cause is "target called exit()" then the code is the
exit code passed to exit.
