{ This test program deals with the
  the delicate problem of
  non commutative FPU instruction
  where the destination register
  is ST(1) to ST(7)

    Whereas Intel interprets
      fdiv st(1),st
    as
      st(1):=st(1) / st
    The ATT read
      fdiv %st,%st(1)
    as
      st(1):=st/st(1)
    Should be tested with
    different output styles :
    for go32v2
      -Aas -Acoff and -Anasmcoff
    for win32
      -Aas -Apecoff and -Anasmwin32
    for linux
      -Aas and -Anasmelf
    }
