Currently the tarballs contain superfluous metadata, like the user name
of the packager and via Pax headers even the PID of the tar process that
packaged the files. We build the monorepo projects directly from the git
repo using "git archive" and for the test-suite we add some flags as
recommended by https://reproducible-builds.org/docs/archives/. We don't
use numeric owners though to be compatible with "git archive".
The advantage of "git archive" is that the releaser doesn't have to
download the tar ball and extract it, rather the archive is built
directly from the repository. This is probably what GitHub uses
internally to produce the tarballs, so I wouldn't expect a difference.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.
