Except as a habit (which I think is a bad one) is there any reason to
have anonymous passes (those with a null pass->name), or (I don't know
if such beast exists) homonym passes (two different passes with equal
pass->name)?
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.
In addition of help debugging of GCC, having each pass be named could be
helpful for other reasons. For example, a plugin machinery would be much
simpler (basically a plugin could say add my pass named foo after every
pass named bar).
