2493 * c-common.c(c_common_nodes_and_builtins): Since variants of
2494 void_type_node get built before it is given a name, we need to
2495 give those variants the name, too.
2496 (complete_array_type): We need to work with the canonical main
2497 type of the array, from which we will build the qualified version.

2499 * print-tree.c (print_node): Display canonical type information
2500 for each type.
2501 * stor-layout.c (layout_type): When we don't know the
2502 alignment of a type for which we're building an array, we end up
2503 guessing wrong, so make the type require structural equality.
2504 * tree.c (make_node_stat): When we build a new type, it is its
2505 own canonical type.
2506 (build_type_attribute_qual_variant): When building an attribute
2507 variant, its canonical type is the non-attribute variant. However,
2508 if the attributes are target-dependent and they differ, we need to
2509 use structural equality checks for this type.
2510 (build_qualified_type): A qualified type is not equivalent to its
2511 unqualified variant; set the canonical type appropriately.
2512 (build_distinct_type_copy): When building a distinct type from
2513 another type, the new type is its own canonical type.
2514 (build_variant_type_copy): When building a new type variant, we
2515 assume that it is equivalent to the original type.
2516 (build_pointer_type_for_mode): When building a pointer type, also
2517 build a canonical type pointer.

2519 also build a canonical type reference.
2520 (build_index_type): When we can't hash an index type (e.g.,
2521 because its maximum value is negative), the index type requires
2522 structural equality tests.
2523 (build_array_type): Build the canonical form of an array type.
2524 (build_function_type): Function types require structural equality,
2525 because they contain default arguments, attributes, etc.
2526 (build_method_type_directly): Ditto for method types.
