--- 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.
