2904 this symbol and signal to the caller that no further processing is
2905 needed. But we don't have the index for this hash-table entry. We
2906 rely here on that the current entry is the first hash-entry with NULL,
2907 which seems brittle. Also, iterating over the hash-table to find that
2908 entry is a linear operation on the number of symbols in this input
2909 file, and this function should take constant time, so that's not good
2910 too. Only comfort is that DataLabel references should only be found in
2911 hand-written assembly code and thus be rare. FIXME: Talk maintainers
