--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Results in
<bb2>
f.constprop ();
return;
and f.constprop is stmt_ends_bb_p () now, the original recursion isn't.
That's because it's likely got an endless loop and noreturn?
calling out IPA-PTA is probably bogus.
f is found const by IPA pure const (but f.constprop isn't updated via
clone hook?) and ends up const looping. IPA-PTA doesn't do anything
and copyprop simply first triggers verification.
