module Register
# GetByte moves a single byte into a register from memory.
# indexes are 1 based (as for slots) , which means we sacrifice a byte of every word
# for our sanity
class GetByte < Getter
# If you had a c array (of int8) and index offset
# the instruction would do register = array[index]
# The arguments are in the order that makes sense for the Instruction name
# So GetSlot means the slot (array and index) moves to the register (last argument)
# def initialize source , array , index , register
# super
# end
# attr_accessor :array , :index , :register
end
# Produce a GetByte instruction.
# from and to are translated (from symbol to register if neccessary)
# but index is left as is.

# from = resolve_to_register from
