--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
There is -Wdisabled-optimization, unfortunately it is used in only 3 places
where we give up due to some limits.
Note not in all cases such warnings are warranted - it's often a concious
decision to limit algorithms to linear growth and warning when you hit
limits to enforce that would lead to the false impression that if you
lift the limit you will get more optimization. I'm thinking of the alias
stmt walkers for example.
