--- Comment #27 from Jeffrey A. Law <law at gcc dot gnu.org> --- We're not using the backward threader to replace DOM's threader yet. I've got a TODO to push on Aldy's patch, but haven't been able to get to it over the last couple weeks. It's an, umm, busy time for us right now. There's really only one issue we need to hash out in Aldy's work and there's a couple proposed workarounds/interm solutions on our way to removing both the forward threader and DOM itself.
