NOTE: The special case of Preg = Preg + Preg, where both input operands are the same Preg (e.g., p3 =
p0+p0;), produces the same opcode as the Logical Shift instruction Preg = Preg << 1 that accomplishes the
same function. Both syntaxes double the input operand value, then place the result in a Preg.
Preg = Preg + Preg

Dreg = Dreg + Dreg
