[Bug target/35488] A incorrect result in a simple division, only in 32-bit gcc.

["pinskia at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

------- Comment #5 from pinskia at gcc dot gnu dot org  2008-03-06 23:15 -------
The division is done and then rounded to 80bits and then rounded again to
64bits.

This is not really a bug.  It is just a misunderstanding on how x87 FPU works.

        fldl    -24(%ebp)
        fldl    -32(%ebp)
        fdivrp  %st, %st(1)
        fstpl   -40(%ebp)

Either use -mfpmath=sse or don't use x86.
