We used to, nobody could come up with a good reason to keep doing it, so we stopped. This was a couple months ago, i still have the emails somewhere. > > comments/ideas? I would start by figuring out why update_ssa + rewrite_into_loop_closed isn't putting SFT.3 into loop closed ssa form. Even if we do put virtual vars back into loop closed, that's still a bug. > > thanks, > dorit >
