--- Comment #2 from Jan Hubicka <hubicka at gcc dot gnu.org> --- Markus, can you add attachment? LTO doesn't really know what C++ language flags was used. I guess because the flags are not on by default, prople will use it only if they actually want to use finals... Docs already mentions it is C++11...
