2817 this symbol and signal to the caller that no further processing is
2818 needed. But we don't have the index for this hash-table entry. We
2819 rely here on that the current entry is the first hash-entry with NULL,
2820 which seems brittle. Also, iterating over the hash-table to find that
2821 entry is a linear operation on the number of symbols in this input
2822 file, and this function should take constant time, so that's not good
2823 too. Only comfort is that DataLabel references should only be found in
2824 hand-written assembly code and thus be rare. FIXME: Talk maintainers
