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
