Thanks for the comment @jkorous.

> I think you could've just used CHECK-DAG to fix the tests. It *might* be a bit more robust. Although just reordering checks seems perfectly fine too. https://llvm.org/docs/CommandGuide/FileCheck.html#the-check-dag-directive. Using std::set here sounds reasonable to me but I'd like @arphaman to be aware of this.

Thanks for pointing me to it - I have a minor preference towards a `sorted` order of outputs vs `order in which we visit the files`. I think a sorted order is much more easy to reason about for a client. Having said that, @arphaman what do you think? If you and Jan both feel that we should maintain the current order, I'll stick to that and not change `Dependencies` to `set`.

> BTW should we change std::vector<std::string> Dependencies; in DependencyCollector to set too?

I think this would change the output of `*.d` file? If so I'm a little hesitant to make that change because of the impact it would have, but once again I'll defer to your judgement on this (I'm very new to LLVM codebase).

> Also, I'm wondering why is the behavior different on Windows.

I confirmed that there are duplicate blacklist.txt files without changing `vector` to `set`. I'm setting up a Windows machine to try to figure out why that is the case. Will share what I find.
