| * 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. |
