/* These should be as small as possible to allow a port to use a trap type
12
   instruction, which the system call # as the trap (the d10v for instance
13
   supports traps 0..31).  An alternative would be to define one trap for doing
14
   system calls, and put the system call number in a register that is not used
15
   for the normal calling sequence (so that you don't have to shift down the
16
   arguments to add the system call number).  Obviously, if these system call
17
   numbers are ever changed, all of the simulators and potentially user code
18
   will need to be updated.  */
