60 * Fragment of the ELF _fini routine that invokes our dtor cleanup.
62 * We make the call by indirection, because in large programs the
63 * .fini and .init sections are not in range of the destination, and
64 * we cannot allow the linker to insert a stub at the end of this
65 * fragment of the _fini function. Further, Itanium does not implement
66 * the long branch instructions, and we do not wish every program to
67 * trap to the kernel for emulation.
69 * Note that we require __do_global_dtors_aux to preserve the GP,
70 * so that the next fragment in .fini gets the right value.
