libunwind CREDITS.TXT is missing - and arguably required to comply with its license

The file system/lib/libunwind/LICENSE.TXT offers two licenses, one of them (NCSA) among other things requiring that...

Neither the names of the LLVM Team, University of Illinois at Urbana-Champaign, nor the names of its contributors may be used to endorse or promote products derived from this Software without specific prior written permission.

The copyright holders are in same file documented as being "the contributors listed in CREDITS.TXT".

Issue is that the referenced file CREDITS.TXT seems missing from source.

How can I be sure to not violate the requirement of the license when I am not told whom I shall avoid to endorse (other than not endorsing anyone on planet Earth)?

Please revive the referenced file CREDITS.TXT both to ease compliance with the offered license, and (also for those who don't care about that NCSA license) to honor those fine people who chose to contribute some of the underpinnings of this nice work.
