Yes. To prevent a dump file. One such example is freeing the internal
data structures. That should not have a dump.
We might add a field (e.g. unsigned avoid_dump) to struct opt_pass for
that, or decide that passes name starting with a star (or whatever
convention people want) do not have any dump file.
I actually proposed a patch on gcc-patches@ which do not dump when the
pass name starts with a dot (better than a star, because following unix
conventions for "hidden" files)
