18666 * print-tree.c (print_node): Display canonical type information
18668 * stor-layout.c (layout_type): When we don't know the
18669 alignment of a type for which we're building an array, we end up
18670 guessing wrong, so make the type require structural equality.
18671 * tree.c (make_node_stat): When we build a new type, it is its
18672 own canonical type.
18673 (build_type_attribute_qual_variant): When building an attribute
18674 variant, its canonical type is the non-attribute variant. However,
18675 if the attributes are target-dependent and they differ, we need to
18676 use structural equality checks for this type.
18677 (build_qualified_type): A qualified type is not equivalent to its
18678 unqualified variant; set the canonical type appropriately.
18679 (build_distinct_type_copy): When building a distinct type from
18680 another type, the new type is its own canonical type.
18681 (build_variant_type_copy): When building a new type variant, we
18682 assume that it is equivalent to the original type.
18683 (build_pointer_type_for_mode): When building a pointer type, also
18684 build a canonical type pointer.
18685 (build_reference_type_for_mode): When building a reference type,
18686 also build a canonical type reference.
18687 (build_index_type): When we can't hash an index type (e.g.,
18688 because its maximum value is negative), the index type requires
18689 structural equality tests.
18690 (build_array_type): Build the canonical form of an array type.
18691 (build_function_type): Function types require structural equality,
18692 because they contain default arguments, attributes, etc.
18693 (build_method_type_directly): Ditto for method types.
