--- Comment #4 from Steven Bosscher <steven at gcc dot gnu.org> 2010-11-02 14:37:21 UTC ---
There is nothing weird about the comment before the quoted code. It just
mentions that the simple solver for global CPROP does not work if there are
unreachable blocks in the CFG (and that the DF solver is insensitive to this).

But oh well, I'll have a look...
