Upstream, there are backends for many different architectures. Of
interest to this list, there is a backend for ppc (32 bit), and ppc64.
*However* the upstream ppc64 backend ONLY works on Mac OS X, because
it makes assumptions[1] about the architecture and the assembler which
don't work with GNU as.
A long time ago, David Woodhouse wrote or modified a ppc64 backend,
which we are now carrying as a separate, non-upstream patch in Fedora.
It generally works, although it has several bugs, of which more later.
Upstream rejected this backend because they don't have the hardware
required to maintain it.
What are their requirements ? Do they just need access to a ppc64 machine ?
I think we might be able to help out with that, I'll talk with Brent if you can
confirm
that ssh access to a machine is sufficient.
