docs: Loads effective address.
  
          Computes the effective address of the second operand (the source operand) and stores it in the first operand
          (destination operand). The source operand is a memory address (offset part) specified with one of the processors
          addressing modes; the destination operand is a general-purpose register. The address-size and operand-size
          attributes affect the action performed by this instruction. The operand-size
          attribute of the instruction is determined by the chosen register; the address-size attribute is determined by the
          attribute of the code segment.
