--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Is the option supposed to be only about the standard global scope operator
new/delete (_Znam etc.) or also user operator new/delete class methods? If the
former, then I agree it is a global property (or at least a per shared
library/binary property, one can arrange stuff with symbol visibility etc.).
Otherwise it is a property of whatever operator new/delete you call.
I think DECL_IS_OPERATOR_{NEW,DELETE} is set on both of these, the standard
ones have
also DECL_IS_REPLACEABLE_OPERATOR flag on them.
Anyway, handling this just in IRA doesn't seem to be enough, surely it should
be also handled during alias analysis etc.
