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. */ | |
