--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
There's eventually the possibility to adjust call_may_clobber_ref_p_1 to
handle calls that are DECL_IS_REPLACEABLE_OPERATOR_NEW_P specially.
Not sure why that is "replaceable" but you mention
new is not replaceable...  Ah, there's also DECL_IS_OPERATOR_NEW_P
(but docs say it's to be used for alias analysis on the resulting ptr).
