--- Comment #10 from Richard Biener <rguenth at gcc dot gnu.org> ---
So we're using RDIV_EXPR for

<fixed_point_type 0x7ffff65610a8 long _Accum>

integer_zerop does not handle FIXED_CST, so previously we considered
all fixed point divisions by constants as not trapping and by non-constants
as trapping.  I can fix that at least as far as using fixed_zerop but I'm n=
ot
sure of the fixed point behavior.=
