Function rustc_driver::driver::phase_2_configure_and_expand

pub fn phase_2_configure_and_expand(sess: &Session, cstore: &CStore, krate: Crate, crate_name: &str, addl_plugins: Option<Vec<String>>) -> Result<Crate, usize>

Unstable (rustc_private)

Run the "early phases" of the compiler: initial cfg processing, loading compiler plugins (including those from addl_plugins), syntax expansion, secondary cfg expansion, synthesis of a test harness if one is to be provided and injection of a dependency on the standard library and prelude.

Returns None if we're aborting after handling -W help.
