--- Comment #3 from Jan Hubicka <hubicka at ucw dot cz> 2010-11-11 14:16:07 UTC --- Hi, handling of weaks and weakrefs is indeed deeply broken with LTO. I plan to look into it after pushing more of the stuff I don't want to get into mainline too late in stage3. That is the inliner bits and -flto changes. Hopefully early next week (I am flying during the weekend). Honza
