Note:
xma.l/xma.lu/xma.h/xma.hu  	- Fixed Point Multiply Add
xmpy.l/xmpy.lu/xmpy.h/xmpy.hu	- Fixed Point Multiply
	(both are on float registers)



Note:	All other Integer operations such as Multiply, Divide, Negate
are complex operations.

	Add with carry look like

		(predicate)	add	r1=r2,r3
		(predicate)	add	r1=r2,r3,1
So, execution use predicates for select way, on which this instruction
will be executed.
