2871 rely here on that the current entry is the first hash-entry with NULL,

2873 entry is a linear operation on the number of symbols in this input
2874 file, and this function should take constant time, so that's not good
2875 too. Only comfort is that DataLabel references should only be found in
2876 hand-written assembly code and thus be rare. FIXME: Talk maintainers
