--- Comment #30 from Martin Jambor <jamborm at gcc dot gnu.org> --- With the above commit, we hae avoided the vast majority of memory use increase. I think that using the same approach to cache ipa_vr structures (used to store results of IPA-VR) could bring further savings (possibly a hundred of megabytes?) so I will try that. In any event, this may no longer qualify as P1.
