11023 * print-tree.c (print_node): Display canonical type information
11025 * stor-layout.c (layout_type): When we don't know the
11026 alignment of a type for which we're building an array, we end up
11027 guessing wrong, so make the type require structural equality.
11028 * tree.c (make_node_stat): When we build a new type, it is its
11029 own canonical type.
11030 (build_type_attribute_qual_variant): When building an attribute
11031 variant, its canonical type is the non-attribute variant. However,
11032 if the attributes are target-dependent and they differ, we need to
11033 use structural equality checks for this type.
11034 (build_qualified_type): A qualified type is not equivalent to its
11035 unqualified variant; set the canonical type appropriately.
11036 (build_distinct_type_copy): When building a distinct type from
11037 another type, the new type is its own canonical type.
11038 (build_variant_type_copy): When building a new type variant, we
11039 assume that it is equivalent to the original type.
11040 (build_pointer_type_for_mode): When building a pointer type, also
11041 build a canonical type pointer.
11042 (build_reference_type_for_mode): When building a reference type,
11043 also build a canonical type reference.
11044 (build_index_type): When we can't hash an index type (e.g.,
11045 because its maximum value is negative), the index type requires
11046 structural equality tests.
11047 (build_array_type): Build the canonical form of an array type.
11048 (build_function_type): Function types require structural equality,
11049 because they contain default arguments, attributes, etc.
11050 (build_method_type_directly): Ditto for method types.
11051 (build_offset_type): Build the canonical offset type.
