Hi Jukka,

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.

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.

==============================================================================
Software from third parties included in the LLVM Project:
==============================================================================
The LLVM Project contains third party software which is under different license
terms. All such code will be identified clearly using at least one of two
mechanisms:
1) It will be in a separate directory tree with its own `LICENSE.txt` or
   `LICENSE` file at the top containing the specific license and restrictions
   which apply to that software, or
2) It will contain specific license and restriction terms at the top of every
   file.

Thanks!

-Chris
