+
+ * gcc-interface/ada-tree.h (TYPE_BY_REFERENCE_P): Delete.
+ (DECL_CONST_ADDRESS_P): New macro.
+ (SET_DECL_ORIGINAL_FIELD_TO_FIELD): Likewise.
+ (SAME_FIELD_P): Likewise.
+ * gcc-interface/decl.c (constructor_address_p): New static function.
+ (gnat_to_gnu_entity) <object>: Set DECL_CONST_ADDRESS_P according to
+ the return value of above function.
+ (gnat_to_gnu_entity) <E_Record_Type>: Force BLKmode for all types
+ passed by reference.
+ <E_Record_Subtype>: Likewise.
+ Set TREE_ADDRESSABLE on the type if it passed by reference.
+ (make_packable_type): Use SET_DECL_ORIGINAL_FIELD_TO_FIELD.
+ (create_field_decl_from): Likewise.
+ (substitute_in_type): Likewise.
+ (purpose_member_field): Use SAME_FIELD_P.
+ * gcc-interface/misc.c (must_pass_by_ref): Test TREE_ADDRESSABLE.
+ * gcc-interface/trans.c (lvalue_required_p): Add ADDRESS_OF_CONSTANT
+ parameter and adjust recursive calls.
+ <N_Explicit_Dereference>: New case.
+ <N_Object_Declaration>: Return 1 if the object is of a class-wide type.
+ Adjust calls to lvalue_required_p. Do not return the initializer of a
+ DECL_CONST_ADDRESS_P constant if an lvalue is required for it.
+ (call_to_gnu): Delay issuing error message for a misaligned actual and
+ avoid the associated back-end assertion. Test TREE_ADDRESSABLE.
+ (gnat_gimplify_expr) <ADDR_EXPR>: Handle non-static constructors.
+ * gcc-interface/utils.c (make_dummy_type): Set TREE_ADDRESSABLE if the
+ type is passed by reference.
+ (convert) <CONSTRUCTOR>: Convert in-place in more cases.
+ * gcc-interface/utils2.c (build_cond_expr): Drop TYPE_BY_REFERENCE_P.
+ (build_simple_component_ref): Use SAME_FIELD_P.

+
+ * gcc-interface/trans.c (Identifier_to_gnu): Use boolean variable.
+ (call_to_gnu): Test gigi's flag TYPE_BY_REFERENCE_P instead of calling
+ front-end's predicate Is_By_Reference_Type. Use consistent order and
+ remove ??? comment. Use original conversion in all cases, if any.
+ * gcc-interface/utils.c (make_dummy_type): Minor tweak.
+ (convert): Use local copy in more cases.
+ <INDIRECT_REF>: Remove deactivated code.
+ (unchecked_convert): Use a couple of local copies.
