Implement N3653 (Member initializers and aggregates) and fix references to 'this' in constexpr constructors.
Implement N3653 (Member initializers and aggregates) and fix
references to 'this' in constexpr constructors.
* class.c (check_field_decls): In C++14 an NSDMI does not make the
class non-aggregate.
* constexpr.c (struct constexpr_ctx): New.
(cxx_bind_parameters_in_call): Handle 'this'.
(cxx_eval_call_expression): Create new constexpr_ctx.
(cxx_eval_component_reference): Check CONSTRUCTOR_NO_IMPLICIT_ZERO.
(initialized_type, init_subob_ctx, verify_ctor_sanity): New.
(cxx_eval_bare_aggregate): Use them. Build CONSTRUCTOR early.
(cxx_eval_vec_init_1): Likewise.
(cxx_eval_constant_expression) [PARM_DECL]: Allow 'this'.
[TARGET_EXPR]: Build new constexpr_ctx.
[PLACEHOLDER_EXPR]: New.
(cxx_eval_outermost_constant_expr): Build new constexpr_ctx. Add
object parameter.
(is_sub_constant_expr): Build new constexpr_ctx.
(potential_constant_expression_1): Handle PLACEHOLDER_EXPR.
Allow 'this'.
* cp-gimplify.c (cp_gimplify_init_expr): Call replace_placeholders.
* cp-tree.h (CONSTRUCTOR_NO_IMPLICIT_ZERO): New.
* error.c (dump_expr): Handle PLACEHOLDER_EXPR.
* init.c (get_nsdmi): Generate PLACEHOLDER_EXPR.
* tree.c (lvalue_kind): Handle PLACEHOLDER_EXPR.
(build_ctor_subob_ref, replace_placeholders): New.
* typeck2.c (store_init_value): Use replace_placeholders.
(process_init_constructor_record): Make zero-init before NSDMI
explicit.
