11 | /* 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. */ | |
