--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
I've already questioned the compile-time cost of those at introduction time.
It is limited by fbi->aa_walked but only if fbi is passed which it is not
when called via ipa_load_from_parm_agg.  Changing the interface to pass
the counter separately and add one to inline_summary similar to the ones
in func_body_info could fix this.
