--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Richard, this is something you've suggested in:
http://gcc.gnu.org/ml/gcc-patches/2016-05/msg01871.html
To answer my question from:
http://gcc.gnu.org/ml/gcc-patches/2016-05/msg01873.html
the bb_rank can be the same for different bbs, if we have more than 65536 basic
blocks on 32-bit hosts.

So, I think we should go for reversion of msg01871.html and instead apply the
other patch.
