--- Comment #35 from Aldy Hernandez <aldyh at gcc dot gnu.org> --- We could also tweak the number of sub-ranges. 8 (??) also sounds good for a few percent less in performance drop, if we care. p.s. I did try the auto_vec thing for a 25% loss in VRP performance, even when using address(), reserve(), etc. I may have gotten something wrong, but it didn't look promising. I could post my attempt and someone could take it from there, but I think the one irange approach with sensible defaults that automatically grow to MAX, better.
