2815 needed. But we don't have the index for this hash-table entry. We
2816 rely here on that the current entry is the first hash-entry with NULL,

2818 entry is a linear operation on the number of symbols in this input
2819 file, and this function should take constant time, so that's not good
2820 too. Only comfort is that DataLabel references should only be found in
2821 hand-written assembly code and thus be rare. FIXME: Talk maintainers
