28547 * print-tree.c (print_node): Display canonical type information
28549 * stor-layout.c (layout_type): When we don't know the
28550 alignment of a type for which we're building an array, we end up
28551 guessing wrong, so make the type require structural equality.
28552 * tree.c (make_node_stat): When we build a new type, it is its
28553 own canonical type.
28554 (build_type_attribute_qual_variant): When building an attribute
28555 variant, its canonical type is the non-attribute variant. However,
28556 if the attributes are target-dependent and they differ, we need to
28557 use structural equality checks for this type.
28558 (build_qualified_type): A qualified type is not equivalent to its
28559 unqualified variant; set the canonical type appropriately.
28560 (build_distinct_type_copy): When building a distinct type from
28561 another type, the new type is its own canonical type.
28562 (build_variant_type_copy): When building a new type variant, we
28563 assume that it is equivalent to the original type.
28564 (build_pointer_type_for_mode): When building a pointer type, also
28565 build a canonical type pointer.
28566 (build_reference_type_for_mode): When building a reference type,
28567 also build a canonical type reference.
28568 (build_index_type): When we can't hash an index type (e.g.,
28569 because its maximum value is negative), the index type requires
28570 structural equality tests.
28571 (build_array_type): Build the canonical form of an array type.
28572 (build_function_type): Function types require structural equality,
28573 because they contain default arguments, attributes, etc.
28574 (build_method_type_directly): Ditto for method types.
