<pre class="bz_comment_text">Our release management at Unity are finding it difficult legal wise to redistribute LLVM,
as LLVM itself does not carry such a NOTICE file that would list the third party licenses of LLVM itself.
Such third party content is found for example at least in the following files
- llvm/lib/Support/COPYRIGHT.regex
- llvm/lib/Support/MD5.cpp
- llvm/lib/Support/xxhash.cpp
- llvm/utils/benchmark/LICENSE
- llvm/utils/unittest/googlemock/LICENSE.txt
- llvm/utils/unittest/googletest/LICENSE.TXT
(in addition to the main license in llvm/LICENSE.txt)
</pre>

<p><font size="-1">The files under llvm/lib/Support may need a
LICENSE.txt. Each of the three files has a different license.
The apparent remaining issue is how to have a LICENSE.txt in
this case and if there are similar cases not accounted for.<br>

Hi Jukka,
<div class=""><br class="">
</div>
<div class="">We discussed this with the LLVM Foundation board.
While we think there is high utility to providing such a
NOTICES file, we don’t know of a way to keep it up to date, and
don’t want to be providing incorrect information for such an
important topic.</div>
<div class=""><br class="">
</div>
<div class="">That said, the llvm/LICENSE.TXT checked into the
code has this information about how to identify third party
licenses in the code base. I hope this is enough to help with
your analysis.</div>

- Missing LLVM NOTICE file<br class="">
is making redistributing LLVM difficult.<br class="">
<br class="">
It was recently noted by our legal review in release
management that<br class="">
LLVM third-party licenses are scattered over different
files, which<br class="">
complicates faithful license-preserving redistribution
of LLVM to our<br class="">
users. Having a grouped license declaration of would
