Agreed, never emit pushf/popf. Sorry I never committed the patch, the cmov issue got hairy and I never got to debugging it :-) I can get back to it if there's interest!

You've definitely got some interest here. I've been looking at your patch on http://reviews.llvm.org/D6629 and I think I'm up to speed on where it's stuck. I'll shoot you an email directly unless you want to keep the effort here on the list.
