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. # def self.get_byte source , array , index , to # from = resolve_to_register from # to = resolve_to_register to # GetByte.new( source , array , index , to) # end end
