-// FIXME(#14344): When linking liballoc with libstd, this library will be linked
-//                as an rlib (it only exists as an rlib). It turns out that an
-//                optimized standard library doesn't actually use *any* symbols
-//                from this library. Everything is inlined and optimized away.
-//                This means that linkers will actually omit the object for this
-//                file, even though it may be needed in the future.
-//
-//                To get around this for now, we define a dummy symbol which
-//                will never get inlined so the stdlib can call it. The stdlib's
-//                reference to this symbol will cause this library's object file
-//                to get linked in to libstd successfully (the linker won't
-//                optimize it out).
