--- Comment #8 from Jan Hubicka <hubicka at gcc dot gnu.org> --- Note that cold attribute is also quite strong since it turns optimize_size codegen that is often a lot slower. Reading the discussion again, I don't think we have a way to make inline keyword ignored by inliner. We can make not_really_inline attribute (better name would be welcome).
