> The original Clang/LLVM runtime is written in C++ with features that are not available in libc and in the NetBSD kernel

  Yeah, I understand why they would write a clone, but "clean-room" has a specific meaning[1], and it's not clear why you would want or need that extra effort here. Of course, I could just be misunderstanding, and they could be using "clean-room" as a synonym for "from scratch", rather than the meaning I linked to.

    Oh, right, I didn't even think about that meaning since we're not in the context of proprietary software. I'm 99.99% sure it's just "from scratch" here.

    My reading is that they didn't look at the Linux implementation (as "clean-room").
