802 The front end assumes that once we have called a method that
803 initializes some class, we can assume the class is initialized. It
804 does this by setting the DECL_INITIAL of the init_test_decl for that
805 class, and no initializations are emitted for that class.
807 However, what if the method that is supposed to do the initialization
808 is itself inlined in the caller? When expanding the called method
809 we'll assume that the class initialization has already been done,
810 because the DECL_INITIAL of the init_test_decl is set.
812 To fix this we remove the DECL_INITIAL (in the caller scope) of all
813 the init_test_decls corresponding to classes initialized by the
814 inlined method. This makes the caller no longer assume that the
815 method being inlined does any class initializations. */
