25227 * print-tree.c (print_node): Display canonical type information
25229 * stor-layout.c (layout_type): When we don't know the
25230 alignment of a type for which we're building an array, we end up
25231 guessing wrong, so make the type require structural equality.
25232 * tree.c (make_node_stat): When we build a new type, it is its
25233 own canonical type.
25234 (build_type_attribute_qual_variant): When building an attribute
25235 variant, its canonical type is the non-attribute variant. However,
25236 if the attributes are target-dependent and they differ, we need to
25237 use structural equality checks for this type.
25238 (build_qualified_type): A qualified type is not equivalent to its
25239 unqualified variant; set the canonical type appropriately.
25240 (build_distinct_type_copy): When building a distinct type from
25241 another type, the new type is its own canonical type.
25242 (build_variant_type_copy): When building a new type variant, we
25243 assume that it is equivalent to the original type.
25244 (build_pointer_type_for_mode): When building a pointer type, also
25245 build a canonical type pointer.
25246 (build_reference_type_for_mode): When building a reference type,
25247 also build a canonical type reference.
25248 (build_index_type): When we can't hash an index type (e.g.,
25249 because its maximum value is negative), the index type requires
25250 structural equality tests.
25251 (build_array_type): Build the canonical form of an array type.
25252 (build_function_type): Function types require structural equality,
25253 because they contain default arguments, attributes, etc.
25254 (build_method_type_directly): Ditto for method types.
