module Virtual # the first instruction we need is to stop. Off course in a real machine this would be a syscall, but that is just # an implementation (in a programm it would be a function). # But in a virtual machine, not only do we need this instruction, # it is indeed the first instruction as just this instruction is the smallest possible programm for the machine. # As such it is the next instruction for any first instruction that we generate. class Halt < Instruction end end
