I am running it.
I don't have access to test names but I can try to add the revision number.
The arch is GNU/Linux 64 bit.

Joshua (as cc) worked on bringing better coverage to Thunderbird and
Firefox:
https://github.com/jcranmer/mozilla-coverage
Maybe I could hack with his tool to get the test information to
LLVM/Clang too.
For now, I haven't put too much effort into it as I wasn't sure how many
people
are using the code coverage (btw, is it possible to have stats on our
website?)

FYI, It is generated by this jenkins job:
http://llvm-jenkins.debian.net/job/llvm-toolchain-codecoverage-binaries/

I have plans to try https://coveralls.io/ to handle that. It should not
be too hard
as I already have most of the things enabled in this job.

For now, it uses autotools and it is managed by the same workflow as the
packages
on llvm.org/apt/
Now, moving to cmake is just a matter of time.

Anyway, don't hesitate if you have other comments or suggestions.
Glad to know it interests folks, despite all it limitations.

Cheers,
