Notes 1.
The operands of SUBW and CMPW are the same as that of ADDW.
2.
Either the second operand is not used, or the second operand is not an operand address.
3.
The code length of some instructions having saddrp2 as saddrp in this combination is short.
4.
The operands of MULUW and DIVUX are the same as that of MULW.
