Hook called by the linker routine which adds symbols from an object

file. We must make indirect symbols for undefined symbols marked with
|
| 2750 |
|
|
STT_DATALABEL, so relocations passing them will pick up that attribute

|
|
and neutralize STO_SH5_ISA32 found on the symbol definition.
|
| 2752 |
|
|
|
| 2753 |

|
There is a problem, though: We want to fill in the hash-table entry for
|
| 2754 |
|
|
this symbol and signal to the caller that no further processing is
|
| 2755 |
|
|
needed. But we don't have the index for this hash-table entry. We
|
| 2756 |
|
|
rely here on that the current entry is the first hash-entry with NULL,
|
| 2757 |
|
|
which seems brittle. Also, iterating over the hash-table to find that
|
| 2758 |
|
|
entry is a linear operation on the number of symbols in this input
|
| 2759 |
|
|
file, and this function should take constant time, so that's not good
|
| 2760 |
|
|
too. Only comfort is that DataLabel references should only be found in
|
| 2761 |
|
|
hand-written assembly code and thus be rare. FIXME: Talk maintainers
|
| 2762 |
|
|
into adding an option to elf_add_symbol_hook (preferably) for the index
|
| 2763 |
|

or the hash entry, alternatively adding the index to Elf_Internal_Sym

(not so good). */
