--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Gcc also tries to limit code growth for the unit also which might be something
you are seeing. You can also try -Winline. Also -flto is becoming more
prevalent and more popular. So you might want to give that a try also with 4.9
and above.
