2774 needed. But we don't have the index for this hash-table entry. We
2775 rely here on that the current entry is the first hash-entry with NULL,
2776 which seems brittle. Also, iterating over the hash-table to find that
2777 entry is a linear operation on the number of symbols in this input
2778 file, and this function should take constant time, so that's not good
2779 too. Only comfort is that DataLabel references should only be found in
2780 hand-written assembly code and thus be rare. FIXME: Talk maintainers
