+# LLVM targets to build support for.
+# Note: this is NOT related to Rust compilation targets. However, as Rust is
+# dependent on LLVM for code generation, turning targets off here WILL lead to
+# the resulting rustc being unable to compile for the disabled architectures.
+# Also worth pointing out is that, in case support for new targets are added to
+# LLVM, enabling them here doesn't mean Rust is automatically gaining said
+# support. You'll need to write a target specification at least, and most
+# likely, teach rustc about the C ABI of the target. Get in touch with the
+# Rust team and file an issue if you need assistance in porting!
