+// This test exercises the `bundle` link argument, which can be turned on or off.
+
+// When building a rlib or staticlib, +bundle means that all object files from the native static
+// library will be added to the rlib or staticlib archive, and then used from it during linking of
+// the final binary.
+
+// When building a rlib -bundle means that the native static library is registered as a dependency
+// of that rlib "by name", and object files from it are included only during linking of the final
+// binary, the file search by that name is also performed during final linking.
+// When building a staticlib -bundle means that the native static library is simply not included
+// into the archive and some higher level build system will need to add it later during linking of
+// the final binary.
+
+// This modifier has no effect when building other targets like executables or dynamic libraries.
+
+// The default for this modifier is +bundle.
+// See https://github.com/rust-lang/rust/pull/95818
+
+// FIXME(Oneirical): cross compile and MSVC
