Thanks for the information. It seems to contain only versions 8 and 9, so I guess what I said was valid only for the previous ones.

The repository looks promising, however the build.sh trying to reach to the internet during the build is disappointing. I would expect that to not help with having reproducible results. I need to look into how distributions approach this.

Domains that require network-isolated builds usually maintain internal mirrors with corresponding dependencies. It is unreasonable to expect from a project of this size to have all tooling it depends on to be available within repository files (moreover, it should build on multiple ISAs and OSes). I doubt you can build LLVM this way or, let's say, OpenJDK.

Well for example golang builds offline just fine, which seems similar in scope? Runtime-based language targeting multiple architectures and operating systems.
