rD
order 32 bits of the 64-bit product of the operands are placed into
rD. Both the operands and the product are interpreted as
unsigned integers, except that if Rc = 1 the first three bits of CR0
field are set by signed comparison of the result to zero. This
instruction may execute faster on some implementations if rB
contains the operand having the smaller absolute value.
