11 | //! Some stuff used by rustc that doesn't have many dependencies | |
12 | //! | |
13 | //! Originally extracted from rustc::back, which was nominally the | |
14 | //! compiler 'backend', though LLVM is rustc's backend, so rustc_back | |
15 | //! is really just odds-and-ends relating to code gen and linking. | |
16 | //! This crate mostly exists to make rustc smaller, so we might put | |
17 | //! more 'stuff' here in the future. It does not have a dependency on | |
18 | //! rustc_llvm. | |
19 | //! | |
20 | //! FIXME: Split this into two crates: one that has deps on syntax, and | |
21 | //! one that doesn't; the one that doesn't might get decent parallel | |
22 | //! build speedups. | |
