--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Of course it has to be evaluated after optimization, that is the whole point of
these attributes.  In this case just IPA ICF should not try to fold error1 with
error2 if it can't use aliases and the functions involved have warning or error
attributes.
