module Mom
# Base class for MOM instructions
# At the base class level instructions are a linked list.
#
# Mom::Instructions are created by the Vool level as an intermediate step
# towards the next level down, the Risc level.
# Mom and Risc are both abstract machines (ie have instructions), so both
# share the linked list functionality (In Util::List)
#
# To convert a Mom instruction to it's Risc equivalent to_risc is called
#
class Instruction
include Util::List
# to_risc, like the name says, converts the instruction to it's Risc equivalent.
# The Risc machine is basically a simple register machine (kind of arm).
# In other words Mom is the higher abstraction and so mom instructions convert
# to many (1-10) risc instructions
#
# The argument that is passed is a MethodCompiler, which has the method and some
# state about registers used. (also provides helpers to generate risc instructions)
