Doesn't seem like it is, if it seems to be broken since some 2013 changes.
It might be in use for projects using older llvm releases, of course.
But those haven't updated their llvm library for a long time, so this
wouldn't be their major problem.

Not really. There's no reason to spend the effort just because "in the
future someone might use it".
If you're saying "I have some half-working things and CppBackend would
be awesome for me", then I guess no one would object to you working on
it, and people would actually help if you needed advice/patch review,

But if we have no one actively interested, and there has been no
active development to the point where it's plain broken since a long
time ago, then we probably want to start proposing its deletion.
There's no point in having people who aren't interested in maintaining
it do all this work if the backend can be so out of date and no one
If it's not usable now and almost no one complains about it being
broken (outside the occasional "Is this working? No.", will those
people notice if it's gone? :-)

Thank you,
