-
-/* There are various ways to handle system calls:
-
-   1) Have a simulator intercept the appropriate trap instruction and
-   directly perform the system call on behalf of the target program.
-   This is the typical way of handling system calls for embedded targets.
-   [Handling system calls for embedded targets isn't that much of an
-   oxymoron as running compiler testsuites make use of the capability.]
-
-   This method of system call handling is done when STATE_ENVIRONMENT
-   is ENVIRONMENT_USER.
-
-   2) Have a simulator emulate the hardware as much as possible.
-   If the program running on the real hardware communicates with some sort
-   of target manager, one would want to be able to run this program on the
-   simulator as well.
-
-   This method of system call handling is done when STATE_ENVIRONMENT
-   is ENVIRONMENT_OPERATING.
