All these phases are coordinated by the driver. To see the exact sequence, look
at the `compile_input` function in [librustc_driver/driver.rs](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_driver/driver/).
The driver (which is found in [librust_driver](https://github.com/rust-lang/rust/tree/master/src/librustc_driver))
handles all the highest level coordination of compilation - handling command
line arguments, maintaining compilation state (primarily in the `Session`), and
calling the appropriate code to run each phase of compilation. It also handles

The driver handles all the highest level coordination of compilation - handling
command-line arguments, maintaining compilation state (primarily in the `Session`),
and calling the appropriate code to run each phase of compilation. It also handles
high level coordination of pretty printing and testing. To create a drop-in
compiler replacement or a compiler replacement, we leave most of compilation
alone and customise the driver using its APIs.
