2760
   There is a problem, though: We want to fill in the hash-table entry for
2761
   this symbol and signal to the caller that no further processing is
2762
   needed.  But we don't have the index for this hash-table entry.  We
2763
   rely here on that the current entry is the first hash-entry with NULL,
2764
   which seems brittle.  Also, iterating over the hash-table to find that
2765
   entry is a linear operation on the number of symbols in this input
2766
   file, and this function should take constant time, so that's not good
2767
   too.  Only comfort is that DataLabel references should only be found in
2768
   hand-written assembly code and thus be rare.  FIXME: Talk maintainers
2769
   into adding an option to elf_add_symbol_hook (preferably) for the index
2770
   or the hash entry, alternatively adding the index to Elf_Internal_Sym
