12059
12060         * c-common.c (c_common_nodes_and_builtins): Since variants of
12061         void_type_node get built before it is given a name, we need to
12062         give those variants the name, too.
12063         (complete_array_type): We need to work with the canonical main
12064         type of the array, from which we will build the qualified version.
12065         * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
12066         * print-tree.c (print_node): Display canonical type information
12067         for each type.
12068         * stor-layout.c (layout_type): When we don't know the
12069         alignment of a type for which we're building an array, we end up
12070         guessing wrong, so make the type require structural equality.
12071         * tree.c (make_node_stat): When we build a new type, it is its
12072         own canonical type.
12073         (build_type_attribute_qual_variant): When building an attribute
12074         variant, its canonical type is the non-attribute variant. However,
12075         if the attributes are target-dependent and they differ, we need to
12076         use structural equality checks for this type.
12077         (build_qualified_type): A qualified type is not equivalent to its
12078         unqualified variant; set the canonical type appropriately.
12079         (build_distinct_type_copy): When building a distinct type from
12080         another type, the new type is its own canonical type.
12081         (build_variant_type_copy): When building a new type variant, we
12082         assume that it is equivalent to the original type.
12083         (build_pointer_type_for_mode): When building a pointer type, also
12084         build a canonical type pointer.
12085         (build_reference_type_for_mode): When building a reference type,
12086         also build a canonical type reference.
12087         (build_index_type): When we can't hash an index type (e.g.,
12088         because its maximum value is negative), the index type requires
12089         structural equality tests.
12090         (build_array_type): Build the canonical form of an array type.
12091         (build_function_type): Function types require structural equality,
12092         because they contain default arguments, attributes, etc.
12093         (build_method_type_directly): Ditto for method types.
12094         (build_offset_type): Build the canonical offset type.
12095         (build_complex_type): Build the canonical vector type.
12096         (make_vector_type): Build the canonical vector type.

12099         (SET_TYPE_STRUCTURAL_EQUALITY): New.
12100         (struct tree_type): Added "canonical" field.
12101         * params.h (VERIFY_CANONICAL_TYPES): New.
12102         * doc/c-tree.texi (TYPE_CANONICAL): Document.

12104         (SET_TYPE_STRUCTURAL_EQUALITY): Document.
12105         * doc/invoke.texi (verify-canonical-types): Document --param
12106         parameter for verifying canonical types.
