--- Comment #22 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Workaround for GCC 5 installed, for GCC 6 we really need to fix this properly
and revert the extra objsz pass.
E.g. the new builtin-object-size-15.c test fails miserably if you change all
__builtin_object_size (, 1) calls to __builtin_object_size (, 3) and it really
shouldn't be hard to construct other testcases that are still mishandled.
Nothing to my knowledge uses __bos (, 2) or __bos (, 3), so the former isn't
that big deal, but the patch is really just a temporary band-aid.
