--- Comment #12 from David Edelsohn <dje at gcc dot gnu.org> ---
There was a separately reported problem of _<filename>.rw_ in the text section.
This was due to read_only_private_data_section.  I have a patch proposed for
that.

_<filename>.ro_ should be part of the .text section. I don't see why it would
contain relocations.

Whoever wrote the AIX support for CMake did a very poor job and apparently
didn't try to understand the semantics of AIX. It's sad that the CMake
maintainers accepted such a broken patch.
