* Simple program to test whether running a user program works.
|

*
|
|
* Just do a "syscall" that shuts down the OS.
|
|
*
|
|
* NOTE: for some reason, user programs with global data structures
|
|
* sometimes haven't worked in the Nachos environment. So be careful
|
|
* out there! One option is to allocate data structures as
|
|
* automatics within a procedure, but if you do this, you have to
|
|
* be careful to allocate a big enough stack to hold the automatics!
