2812 needed. But we don't have the index for this hash-table entry. We
2813 rely here on that the current entry is the first hash-entry with NULL,

2815 entry is a linear operation on the number of symbols in this input
2816 file, and this function should take constant time, so that's not good
2817 too. Only comfort is that DataLabel references should only be found in
2818 hand-written assembly code and thus be rare. FIXME: Talk maintainers
