--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
IMO it should be purely growth/unrolled-insns bound, the bound on the actual
unrolled iterations is somewhat artificial (to avoid really large unrolls
when we estimate the unrolled body to be zero, thus never hit any of the other
limits). That said, I think we should get better at estimating growth - I
don't
think we get that the reads from the constant arrays get elided? (though
that's
not always an optimal thing)
See the proposal on better estimation I had last year.
