However I work on a DEC Ultrix system, I post here because my
question deal with which comes from MIPS.

First, when I use the flag -V I get 'Mips Computer Systems 2.10'.
Now my questions:
  1)is there a way to use directly the div instructions of
    the R3000 without making use of the 'macro' provided by as?
    (you can do it with the mult instructions, but seemingly not
    with div)
  2)when I multiply 2 16 bit numbers can I get the result from the
    lo register before complete achievement of the mult (ie 12 cycles)
    or will the R3000 lock anyway? what about the R4000?
