--- Comment #4 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
I have some code that makes it possible to attach summaries to references (like
we do for calls and symbols) and then mark addresses that are never used for
compoarsion. Similarly we could probably mark readonly addresses.
We could even squeeze out a bit in the reference representation itself.
Is there easy way to tell if address is never read from during IPA summary
generation time?
