10/* These should be as small as possible to allow a port to use a trap type
11   instruction, which the system call # as the trap (the d10v for instance
12   supports traps 0..31).  An alternative would be to define one trap for doing
13   system calls, and put the system call number in a register that is not used
14   for the normal calling sequence (so that you don't have to shift down the
15   arguments to add the system call number).  Obviously, if these system call
16   numbers are ever changed, all of the simulators and potentially user code
17   will need to be updated.  */
