Either file can presumably exist without the other, but do not differ

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

(not so good). */
