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