-// Implementation for Linux. This relies on the linker's support for weak
-// symbols. We don't use this approach on Apple platforms because it requires
-// clients of LibFuzzer to pass ``-U _<symbol_name>`` to the linker to allow
-// weak symbols to be undefined. That is a complication we don't want to expose
-// to clients right now.
