2811 Hook called by the linker routine which adds symbols from an object
2812 file. We must make indirect symbols for undefined symbols marked with
2813 STT_DATALABEL, so relocations passing them will pick up that attribute
2814 and neutralize STO_SH5_ISA32 found on the symbol definition.
2815
2816 There is a problem, though: We want to fill in the hash-table entry for
2817 this symbol and signal to the caller that no further processing is
2818 needed. But we don't have the index for this hash-table entry. We
2819 rely here on that the current entry is the first hash-entry with NULL,
2820 which seems brittle. Also, iterating over the hash-table to find that
2821 entry is a linear operation on the number of symbols in this input
2822 file, and this function should take constant time, so that's not good
2823 too. Only comfort is that DataLabel references should only be found in
2824 hand-written assembly code and thus be rare. FIXME: Talk maintainers
2825 into adding an option to elf_add_symbol_hook (preferably) for the index
