--- Comment #2 from Marc Glisse <glisse at gcc dot gnu.org> --- What is the point of inlining it? It isn't a hot call (called once from main). And unless you are using something like -flto of -fwhole-program (which would turn the function static), it has to be emitted as a separate function as well, so inlining it increases code size.
