 * Fragment of the ELF _fini routine that invokes our dtor cleanup.

 *

 * We make the call by indirection, because in large programs the

 * .fini and .init sections are not in range of the destination, and

 * we cannot allow the linker to insert a stub at the end of this

 * fragment of the _fini function.  Further, Itanium does not implement

 * the long branch instructions, and we do not wish every program to

 * trap to the kernel for emulation.

 *

 * Note that we require __do_global_dtors_aux to preserve the GP,

 * so that the next fragment in .fini gets the right value.
