2692 Hook called by the linker routine which adds symbols from an object
2693 file. We must make indirect symbols for undefined symbols marked with
2694 STT_DATALABEL, so relocations passing them will pick up that attribute
2695 and neutralize STO_SH5_ISA32 found on the symbol definition.
2697 There is a problem, though: We want to fill in the hash-table entry for
2698 this symbol and signal to the caller that no further processing is
2699 needed. But we don't have the index for this hash-table entry. We
2700 rely here on that the current entry is the first hash-entry with NULL,
2701 which seems brittle. Also, iterating over the hash-table to find that
2702 entry is a linear operation on the number of symbols in this input
2703 file, and this function should take constant time, so that's not good
2704 too. Only comfort is that DataLabel references should only be found in
2705 hand-written assembly code and thus be rare. FIXME: Talk maintainers
