Yes.  The assembly language isn't really parseable otherwise.

The idea here was to provide the extended version under a new name, and
keep the old interface around so that we don't have to make changes in
all the ports.  If you prefer to have every occurrence of _dl_find_hash
changed, I guess I can do that, although it's more error-prone.

Oh, that's what you mean, ok - no problem.
