--- Comment #11 from Wilco <wilco at gcc dot gnu.org> --- Thanks, that's actually a very clear description of the issue. It means during rematerialization we should avoid DUP and revert to literal loads on the assumption that they could be placed in hot loops. However remat doesn't use costs at all, and there are no hooks, so I need to look into how it could be done.
