*1 Marked by - - - cannot be selected.
*2 If src is An and dest is Rn while the size specifier (.size) is (.W), the number of cycles above is increased by 1.
*3 If src is not An and dest is Rn or An while the size specifier (.size) is (.W), the number of cycles above is
increased by 1.
*4 If dest is neither Rn nor An while the size specifier (.size) is (.W), the number of cycles above is increased by 2.
