        * tree.c (rvalue): Use lvalue_or_rvalue_with_address_p.

        PR c++/37206
        * cp-tree.h (enum cp_lvalue_kind_flags): Add clk_rvalueref.
        * tree.c (lvalue_p_1): Return it.  Remove
        treat_class_rvalues_as_lvalues parm.
        (real_lvalue_p): Disallow pseudo-lvalues here.
        (lvalue_or_rvalue_with_address_p): New fn.
        * call.c (initialize_reference): Use it instead of real_lvalue_p.

        * init.c (build_new_1): Handle initializer list as array initializer.
        (build_vec_init): Likewise.
        * typeck.c (cp_build_modify_expr): Likewise.
        * typeck2.c (process_init_constructor_array): Error rather than abort
        if too many initializers.
