From a very quick search I can't seem to find such a branch. Judging from https://github.com/llvm/llvm-project/releases https://github.com/llvm/llvm-project/releases they seem to occasionally branch release candidate branches from master, every two weeks or so. That's very far from a well-tested master updated several times a day. Continuous integration for compilers is a well-understood problem. There are posts in this thread explaining how Rust handles it. I understand that it's a royal pain to set up and maintain. I am a compiler engineer and am happy to work on compilation stuff but wouldn't want to touch our CI system with a ten-foot pole. But LLVM is a project driven by Google and Apple, there are really no excuses for not finding the people willing to do this.
