--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
I had patches to implement the suggestion, work on outermost loops separately.
Of course it won't help once you wrap all of them in a single outer loop
(which is why I didn't end up committing this).
Re-measuring state of current trunk would be still nice (I think we must
have improved over the 1GB).
