Calling Convention: Syscall number goes in r2, parameters in r3+, syscall handler at 0x3700.

Example: For _exit(42):

li      r2, 149        # Syscall number for _exit
li      r3, 42         # First argument: exit code
li      r0, 0x3700     # Syscall handler address
mtctr   r0             # Move to count register
bctrl                  # Branch to syscall handler
