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