19575 * c-common.c (c_common_nodes_and_builtins): Since variants of
19576 void_type_node get built before it is given a name, we need to
19577 give those variants the name, too.
19578 (complete_array_type): We need to work with the canonical main
19579 type of the array, from which we will build the qualified version.

19581 * print-tree.c (print_node): Display canonical type information
19583 * stor-layout.c (layout_type): When we don't know the
19584 alignment of a type for which we're building an array, we end up
19585 guessing wrong, so make the type require structural equality.
19586 * tree.c (make_node_stat): When we build a new type, it is its
19587 own canonical type.
19588 (build_type_attribute_qual_variant): When building an attribute
19589 variant, its canonical type is the non-attribute variant. However,
19590 if the attributes are target-dependent and they differ, we need to
19591 use structural equality checks for this type.
19592 (build_qualified_type): A qualified type is not equivalent to its
19593 unqualified variant; set the canonical type appropriately.
19594 (build_distinct_type_copy): When building a distinct type from
19595 another type, the new type is its own canonical type.
19596 (build_variant_type_copy): When building a new type variant, we
19597 assume that it is equivalent to the original type.
19598 (build_pointer_type_for_mode): When building a pointer type, also
19599 build a canonical type pointer.
19600 (build_reference_type_for_mode): When building a reference type,
19601 also build a canonical type reference.
19602 (build_index_type): When we can't hash an index type (e.g.,
19603 because its maximum value is negative), the index type requires
19604 structural equality tests.
19605 (build_array_type): Build the canonical form of an array type.
19606 (build_function_type): Function types require structural equality,
19607 because they contain default arguments, attributes, etc.
19608 (build_method_type_directly): Ditto for method types.
19609 (build_offset_type): Build the canonical offset type.
19610 (build_complex_type): Build the canonical vector type.
