43 * Fragment of the ELF _init routine that invokes our dtor cleanup.
45 * We make the call by indirection, because in large programs the
46 * .fini and .init sections are not in range of the destination, and
47 * we cannot allow the linker to insert a stub at the end of this
48 * fragment of the _fini function. Further, Itanium does not implement
49 * the long branch instructions, and we do not wish every program to
50 * trap to the kernel for emulation.
52 * Note that we require __do_global_ctors_aux to preserve the GP,
53 * so that the next fragment in .fini gets the right value.
