   1 //! Some stuff used by rustc that doesn't have many dependencies
   2 //!
   3 //! Originally extracted from rustc::back, which was nominally the
   4 //! compiler 'backend', though LLVM is rustc's backend, so rustc_target
   5 //! is really just odds-and-ends relating to code gen and linking.
   6 //! This crate mostly exists to make rustc smaller, so we might put
   7 //! more 'stuff' here in the future. It does not have a dependency on
   8 //! LLVM.
