  25 # LTO is a special front end.  From a user's perspective it is not
  26 # really a language, but a middle end feature.  However, the GIMPLE
  27 # reading module is implemented as a front end, so enabling LTO means
  28 # enabling this "language". To enable LTO functionality, use
  29 # --enable-lto when configuring the compiler.
