the job of figuring out which values a closure uses and how, so it can decide
whether to capture a given variable by shared reference, mutable reference, or
by move. rustc also has to figure out which the closure traits ([`Fn`][fn],

You can see the exact dependencies by reading the `Cargo.toml` for the various

One final thing: [`src/llvm-project`] is a submodule for our fork of LLVM.
During bootstrapping, LLVM is built and the [`src/librustc_llvm`] and
[`src/rustllvm`] crates contain rust wrappers around LLVM (which is written in
C++), so that the compiler can interface with it.
