I have tried to build r27 in my fork with all darwin and windows prebuilts removed. Build Toolchain job failed with out of disk space after running 4h 39m 54s.

I could try to shallow clone every project in manifest file. That may remove git version information (not the clang/llvm actual version). Is that ok for this project?

Also, do you build lldb? If not, lldb dependencies can be removed too.

IMO this will not work. During the build process, patches are applied according to the output of git rev-list --count HEAD, and shallow clone will obviously break it.

I didn't compile lldb. I don't think that removing the source code of lldb's deps will help a lot anyway..

But the patches were applied correctly according to the logs. I have compared the logs between shallow clone and full history clone. I found similar patches are applied.

I'm not sure about it. Maybe we can give it a try.
