Subversion does not warn you when = you remove the last files from a directory, and it also does not = automatically remove such empty directories, like Git. Hence, those directories tend = to stick around, because every simply forgets about them. With regards to those empty directories under contrib/llvm, those were = actually imported from upstream. But since the llvm project will switch to Git = soon, this problem will automagically disappear. :-) -Dimitry --Apple-Mail=_BB7FCB97-51CC-4187-9732-B98C4374371D Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.2 iF0EARECAB0WIQR6tGLSzjX8bUI5T82wXqMKLiCWowUCXXf8TwAKCRCwXqMKLiCW o7cGAKDOzpwbyGGwYSL74TSUjC1JrYpdOwCgsDHOh2aYTppN0uAQ2qqBGWwKWPI= =6CWy -----END PGP SIGNATURE----- --Apple-Mail=_BB7FCB97-51CC-4187-9732-B98C4374371D--
