--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Ah, because they may be NaN if x or y were NaN.  Works ok with
-ffinite-math-only,
PRE already figures out the result is 1.

Thus invalid.

And thus if we performed this simplification on GENERIC somehow that was likely
an invalid transform.
