# - cpu_instructions: The sequence of cpu specific instructions that the
# risc_instructions was compiled to
# Instructions derive from class Instruction and form a linked list
# - binary: The binary (jumpable) code that the instructions get assembled into
# - arguments_type: A type object describing the arguments (name+types) to be passed
