2687 Hook called by the linker routine which adds symbols from an object
2688 file. We must make indirect symbols for undefined symbols marked with
2689 STT_DATALABEL, so relocations passing them will pick up that attribute
2690 and neutralize STO_SH5_ISA32 found on the symbol definition.
2691
2692 There is a problem, though: We want to fill in the hash-table entry for
2693 this symbol and signal to the caller that no further processing is
2694 needed. But we don't have the index for this hash-table entry. We
2695 rely here on that the current entry is the first hash-entry with NULL,
2696 which seems brittle. Also, iterating over the hash-table to find that
2697 entry is a linear operation on the number of symbols in this input
2698 file, and this function should take constant time, so that's not good
2699 too. Only comfort is that DataLabel references should only be found in
2700 hand-written assembly code and thus be rare. FIXME: Talk maintainers
2701 into adding an option to elf_add_symbol_hook (preferably) for the index
2702 or the hash entry, alternatively adding the index to Elf_Internal_Sym
