--- Comment #3 from Richard Guenther <rguenth at gcc dot gnu.org> 2010-10-10 13:31:30 UTC --- This btw fails nearly all libstdc++ tests when built with -flto. Jason, is there no way to avoid lang_type to leak into the middle-end like this? Why do we need to use lang_type for nullptr and cannot use void * with some lang-specific flag? This really breaks LTO badly for 4.6, so if it cannot be resolved in the FE I guess I'll just drop all lang_type nodes at streaming time replacing them with ptr_type_node (ugh).
