//! Cranelift code generation library.
#![deny(missing_docs)]
#![no_std]
// Various bits and pieces of this crate might only be used for one platform or
// another, but it's not really too useful to learn about that all the time. On
// CI we build at least one version of this crate with `--features all-arch`
// which means we'll always detect truly dead code, otherwise if this is only
// built for one platform we don't have to worry too much about trimming
// everything down.
