So there's no need for gc_mark_hook to return the section of the symbol on the
R_SPARC_TLS_GD_CALL? ie. you're sure that section will be marked from some
other reloc? If not then something like the following is needed.
if (info->shared)
switch (SPARC_ELF_R_TYPE (rel->r_info))
{
case R_SPARC_TLS_GD_CALL:
case R_SPARC_TLS_LDM_CALL:
tga = elf_link_hash_lookup (elf_hash_table (info), "__tls_get_addr",
FALSE, FALSE, TRUE);
BFD_ASSERT (tga != NULL);
tga->mark = 1;
if (tga->u.weakdef != NULL)
tga->u.weakdef->mark = 1;
/* If __tls_get_addr might ever have a regular definition,
then we need to mark its section too. */
rsec = _bfd_elf_gc_mark_hook (sec, info, rel, tga, NULL);
if (rsec && !rsec->gc_mark)
{
if (bfd_get_flavour (rsec->owner) != bfd_target_elf_flavour
|| (rsec->owner->flags & DYNAMIC) != 0)
rsec->gc_mark = 1;
else
/* FIXME: return error from _bfd_elf_gc_mark somehow. */
_bfd_elf_gc_mark (info, rsec, _bfd_sparc_elf_gc_mark_hook);
}
}
