2813 needed. But we don't have the index for this hash-table entry. We
2814 rely here on that the current entry is the first hash-entry with NULL,

2816 entry is a linear operation on the number of symbols in this input
2817 file, and this function should take constant time, so that's not good
2818 too. Only comfort is that DataLabel references should only be found in
2819 hand-written assembly code and thus be rare. FIXME: Talk maintainers
