--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. Two pieces depending on SHORT_CIRCUIT_...
maybe_fold_and_comparisons for ifcombine and a match.pd pattern for
_1 = a_3(D) >= 0;
_2 = b_4(D) >= 0;
_5 = _1 & _2;
that should also make it work through maybe_fold_and_comparisons. We have
something like this in fold-const.c btw.
