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 [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.2 iF0EARECAB0WIQR6tGLSzjX8bUI5T82wXqMKLiCWowUCXXf8TwAKCRCwXqMKLiCW o7cGAKDOzpwbyGGwYSL74TSUjC1JrYpdOwCgsDHOh2aYTppN0uAQ2qqBGWwKWPI= =6CWy -----END PGP SIGNATURE-----
