12379
12380         * c-common.c (c_common_nodes_and_builtins): Since variants of
12381         void_type_node get built before it is given a name, we need to
12382         give those variants the name, too.
12383         (complete_array_type): We need to work with the canonical main
12384         type of the array, from which we will build the qualified version.
12385         * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
12386         * print-tree.c (print_node): Display canonical type information
12387         for each type.
12388         * stor-layout.c (layout_type): When we don't know the
12389         alignment of a type for which we're building an array, we end up
12390         guessing wrong, so make the type require structural equality.
12391         * tree.c (make_node_stat): When we build a new type, it is its
12392         own canonical type.
12393         (build_type_attribute_qual_variant): When building an attribute
12394         variant, its canonical type is the non-attribute variant. However,
12395         if the attributes are target-dependent and they differ, we need to
12396         use structural equality checks for this type.
12397         (build_qualified_type): A qualified type is not equivalent to its
12398         unqualified variant; set the canonical type appropriately.
12399         (build_distinct_type_copy): When building a distinct type from
12400         another type, the new type is its own canonical type.
12401         (build_variant_type_copy): When building a new type variant, we
12402         assume that it is equivalent to the original type.
12403         (build_pointer_type_for_mode): When building a pointer type, also
12404         build a canonical type pointer.
12405         (build_reference_type_for_mode): When building a reference type,
12406         also build a canonical type reference.
12407         (build_index_type): When we can't hash an index type (e.g.,
12408         because its maximum value is negative), the index type requires
12409         structural equality tests.
12410         (build_array_type): Build the canonical form of an array type.
12411         (build_function_type): Function types require structural equality,
12412         because they contain default arguments, attributes, etc.
12413         (build_method_type_directly): Ditto for method types.
12414         (build_offset_type): Build the canonical offset type.
12415         (build_complex_type): Build the canonical vector type.
12416         (make_vector_type): Build the canonical vector type.
12417         * tree.h (TYPE_CANONICAL): New.
12418         (TYPE_STRUCTURAL_EQUALITY_P): New.
12419         (SET_TYPE_STRUCTURAL_EQUALITY): New.
12420         (struct tree_type): Added "canonical" field.
12421         * params.h (VERIFY_CANONICAL_TYPES): New.
12422         * doc/c-tree.texi (TYPE_CANONICAL): Document.
12423         (TYPE_STRUCTURAL_EQUALITY_P): Document.
12424         (SET_TYPE_STRUCTURAL_EQUALITY): Document.
12425         * doc/invoke.texi (verify-canonical-types): Document --param
12426         parameter for verifying canonical types.
