2767 Hook called by the linker routine which adds symbols from an object
2768 file. We must make indirect symbols for undefined symbols marked with
2769 STT_DATALABEL, so relocations passing them will pick up that attribute
2770 and neutralize STO_SH5_ISA32 found on the symbol definition.
2771
2772 There is a problem, though: We want to fill in the hash-table entry for
2773 this symbol and signal to the caller that no further processing is
2774 needed. But we don't have the index for this hash-table entry. We
2775 rely here on that the current entry is the first hash-entry with NULL,
2776 which seems brittle. Also, iterating over the hash-table to find that
2777 entry is a linear operation on the number of symbols in this input
2778 file, and this function should take constant time, so that's not good
2779 too. Only comfort is that DataLabel references should only be found in
2780 hand-written assembly code and thus be rare. FIXME: Talk maintainers
2781 into adding an option to elf_add_symbol_hook (preferably) for the index
