--- Comment #25 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > AFAIR, the difference is that the Ada runtime (when built during each stage) > is made as convenience (statically linked) libs, whereas libada is built > shared - so there will (probably) be different code-gen paths. ("Probably" > is only stated because x86-64 Darwin should always build PIC code for m64 so > if it was doing something different that would, indeed be an accident) No, as Arno said, there is no difference w or w/o --disable-libada.
