2691 | Hook called by the linker routine which adds symbols from an object | |
2692 | file. We must make indirect symbols for undefined symbols marked with | |
2693 | STT_DATALABEL, so relocations passing them will pick up that attribute | |
2694 | and neutralize STO_SH5_ISA32 found on the symbol definition. | |
2695 | ||
2696 | There is a problem, though: We want to fill in the hash-table entry for | |
2697 | this symbol and signal to the caller that no further processing is | |
2698 | needed. But we don't have the index for this hash-table entry. We | |
2699 | rely here on that the current entry is the first hash-entry with NULL, | |
2700 | which seems brittle. Also, iterating over the hash-table to find that | |
2701 | entry is a linear operation on the number of symbols in this input | |
2702 | file, and this function should take constant time, so that's not good | |
2703 | too. Only comfort is that DataLabel references should only be found in | |
2704 | hand-written assembly code and thus be rare. FIXME: Talk maintainers | |
2705 | into adding an option to elf_add_symbol_hook (preferably) for the index | |
2706 | or the hash entry, alternatively adding the index to Elf_Internal_Sym | |
