    My question regards treatment of .data/.bss.  Is all of the read/write data supposed
    to be preserved across unexec?

It is abslutely necessary to dump the bss as data because it is filled
with Lisp objects that must be preserved in the dumped Emacs.

    Newer versions of the AIX linker reorder objects, so the manual placement of
    lastfile.o on the link line doesn't cause the desired memory layout.  The
    option -bnoobjreorder needs to be added to the link command line to turn off
    object reordering.

Can you fix it using that method?
