rD
rB. A 32-bit quotient is formed. The 32-bit quotient is placed into
rD. The remainder is not supplied as a result.
Both operands and the quotient 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. The quotient is
the unique unsigned integer that satisfies the equation—
dividend = (quotient
attempt is made to perform the division—<anything>
the contents of rD are undefined as are the contents of the LT,
GT, and EQ bits of the CR0 field (if Rc = 1). In this case, if OE =
1 then OV is set.
The 32-bit unsigned remainder of dividing the contents of rA by
the contents of rB can be computed as follows:
