--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
as I mentioned function pointer has nothing to do with it, you can see the
behavior with:
__attribute((__section__("mysection"))) int const cx = -42;
typedef const int *iptr;

__attribute((__section__("mysection")))  const iptr cxptr= & cx;
---- CUT ----
With -fPIE/-fPIC (which means the relocation needs to be done at runtime and
such), get:
        .section        mysection,"aw",@progbits

With -fno-PIE/-fno-PIC:
        .section        mysection,"a",@progbits
