Couple of driver interface improvements * Pass Session to `make_codegen_backend` callback. This simplifies some code in miri. * Move env/file_depinfo from ParseSess to Session. There is no reason it has to be in ParseSess rather than Session. * Rename hash_untracked_state to track_state to indicate that it isn't just used for hashing state, but also for adding env vars and files to be tracked through the dep info file.
The driver crate is effectively the "main" function for the rust
compiler. It orchestrates the compilation process and "knits together"
the code from the other crates within rustc. This crate itself does
not contain any of the "main logic" of the compiler (though it does
have some code related to pretty printing or other minor compiler
options).
For more information about how the driver works, see the rustc dev guide.
