Nico, Mike, mind taking a look at this?

[Nico, 2016-03-02 01:12:24]

Do we really want to just check in these files? Don't we'd rather want to set up
something like https://chromium.googlesource.com/external/llvm.org/llvm/ (except
for libfuzzer) and pull that in via DEPS? (ask on http://crbug.com/587658 to get
that mirror)

That way, rolling libfuzzer only requires changing a single number in deps

I think libfuzzer is part of the llvm tree under lib/Fuzzer? Is there a way to
only pull that directory via DEPS without pulling the rest of LLVM?

Not with git; you'd have to set up a separate git mirror.

Maybe you could pull it via svn from the
https://src.chromium.org/viewvc/llvm-project/llvm/trunk/lib/Fuzzer/ mirror, but
I think infra would prefer if you ask them for a mirror for that subdirectory.

Cool, filed a bug (https://crbug.com/591259). Will update this CL once that's

What is the minimum I could add? No other test sources in llvm have licenses. I
wouldn't want to add full multi-line headers.

At the start of each .cpp file seems to do the trick.
