2906 this symbol and signal to the caller that no further processing is
2907 needed. But we don't have the index for this hash-table entry. We
2908 rely here on that the current entry is the first hash-entry with NULL,
2909 which seems brittle. Also, iterating over the hash-table to find that
2910 entry is a linear operation on the number of symbols in this input
2911 file, and this function should take constant time, so that's not good
2912 too. Only comfort is that DataLabel references should only be found in
2913 hand-written assembly code and thus be rare. FIXME: Talk maintainers
