I'd like to echo this request. I help maintain a downstream LLVM
repository that I haven't yet been able to migrate to the monorepo
structure (I know, I will! It's a work in progress :) ). I'd like to
rebase our downstream patches on top of a 9.0.0 release branch, but am
currently unable to do so because the mirrors do not have such a

Alternatively, does anyone have a convenient way to determine which
mirror commit represents the branching point of the 9.0.0 release
branch? I tried determining this for myself by checking out the
branching point r366423 in each SVN sub-repository and seeing the most
recent commit, and I got these.

* https://github.com/llvm-mirror/lldb/commit/aaecb53ef71efec5d4bcfcd677e984ab971e2d99,

So I'm thinking that checking out the mirror commits above and
applying the same patches on top as applied to the llvm-project
release branch would get me a mirror release branch. But if anyone can
confirm that, or if they know an easier way to find these mirror
commits, please let me know. Thanks!
