2810 needed. But we don't have the index for this hash-table entry. We
2811 rely here on that the current entry is the first hash-entry with NULL,

2813 entry is a linear operation on the number of symbols in this input
2814 file, and this function should take constant time, so that's not good
2815 too. Only comfort is that DataLabel references should only be found in
2816 hand-written assembly code and thus be rare. FIXME: Talk maintainers
