28538 * print-tree.c (print_node): Display canonical type information
28540 * stor-layout.c (layout_type): When we don't know the
28541 alignment of a type for which we're building an array, we end up
28542 guessing wrong, so make the type require structural equality.
28543 * tree.c (make_node_stat): When we build a new type, it is its
28544 own canonical type.
28545 (build_type_attribute_qual_variant): When building an attribute
28546 variant, its canonical type is the non-attribute variant. However,
28547 if the attributes are target-dependent and they differ, we need to
28548 use structural equality checks for this type.
28549 (build_qualified_type): A qualified type is not equivalent to its
28550 unqualified variant; set the canonical type appropriately.
28551 (build_distinct_type_copy): When building a distinct type from
28552 another type, the new type is its own canonical type.
28553 (build_variant_type_copy): When building a new type variant, we
28554 assume that it is equivalent to the original type.
28555 (build_pointer_type_for_mode): When building a pointer type, also
28556 build a canonical type pointer.
28557 (build_reference_type_for_mode): When building a reference type,
28558 also build a canonical type reference.
28559 (build_index_type): When we can't hash an index type (e.g.,
28560 because its maximum value is negative), the index type requires
28561 structural equality tests.
28562 (build_array_type): Build the canonical form of an array type.
28563 (build_function_type): Function types require structural equality,
28564 because they contain default arguments, attributes, etc.
28565 (build_method_type_directly): Ditto for method types.
