http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46905 --- Comment #2 from Richard Guenther <rguenth at gcc dot gnu.org> 2010-12-16 14:36:44 UTC --- I suppose using the linker plugin shows similar effects at link stage? I think this is a specs issue, the driver passes on -flto* if -fno-lto was on the commandline.
