+//! Some stuff used by rustc that doesn't have many dependencies
+//!
+//! Originally extracted from rustc::back, which was nominally the
+//! compiler 'backend', though LLVM is rustc's backend, so rustc_target
+//! is really just odds-and-ends relating to code gen and linking.
+//! This crate mostly exists to make rustc smaller, so we might put
+//! more 'stuff' here in the future.  It does not have a dependency on
+//! rustc_llvm.
+//!
+//! FIXME: Split this into two crates: one that has deps on syntax, and
+//! one that doesn't; the one that doesn't might get decent parallel
+//! build speedups.
