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