  The overwhelming bulk of users are going to install a binary package, not build from source. LLVM 9.0 with Clang, a huge array of tools, etc, is 1.9GB on macOS.

    The point of open source is that individuals from the community can read and modify their tools. Anything that makes that harder is a bad thing, it might be justified but it’s still bad.

  Note that's only when building in debug mode, which doesn't seem to be needed by many people. Most developers who compile from source (eg working on LLVM itself) don't need that. Building in release mode is much smaller probably ~5GB or so (from rough memory, it's been a while).
