Missing git mirror for debug-info tests?

I am not able to checkout the debug-info tests from the git mirror like I can for other repos.

git clone http://llvm.org/git/debuginfo-tests.git
Cloning into 'debuginfo-tests'...
fatal: repository 'http://llvm.org/git/debuginfo-tests.git/’ not found

Is this repo not mirrored in git like the rest?
