--- Comment #4 from Alan Modra <amodra at gmail dot com> ---
This one is a real pain. It's due to gold adding stubs at the end of a section
rather than as ld.bfd does, in a separate section inserted just before one of
the group sections. I think I need to rewrite the powerpc.cc group_sections
code, throwing out --stub-group-size negative meaning that the stubs are always
before the branch and switch to --stub-group-size negative meaning that the
stubs are always *after* the branch. The problem is that if we want stubs
before branches, then the stubs must be added to the previous section. Adding
to the previous section is a disaster if there is a large gap between the
previous section and the group. That's exactly what happens with the kernel:
stubs are attached to a .meminit.text input section (last in output .text) for
the group of .init.text and .exit.text sections.
