--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Even though I think there is a bug here. I think the best way to work around
this issue is do:
unsigned long
resolve_ifunc (unsigned long value,
const struct link_map *map, const struct link_map *sym_map)
{
Elf64_FuncDesc opd;
if (map != sym_map
&& sym_map != dl_rtld_map
&& !sym_map->l_relocated)
{
Elf64_FuncDesc *func = (Elf64_FuncDesc *) value;
opd.fd_func = func->fd_func + sym_map->l_addr;
opd.fd_toc = func->fd_toc + sym_map->l_addr;
opd.fd_aux = func->fd_aux;
value = (unsigned long) &opd;
}
asm("":"+r"(value): : "memory");
return ((unsigned long (*) (unsigned long)) value) (dl_hwcap);
}
