28557 * c-common.c (c_common_nodes_and_builtins): Since variants of
28558 void_type_node get built before it is given a name, we need to
28559 give those variants the name, too.
28560 (complete_array_type): We need to work with the canonical main

28565 * stor-layout.c (layout_type): When we don't know the
28566 alignment of a type for which we're building an array, we end up
28567 guessing wrong, so make the type require structural equality.
28568 * tree.c (make_node_stat): When we build a new type, it is its
28569 own canonical type.
28570 (build_type_attribute_qual_variant): When building an attribute
28571 variant, its canonical type is the non-attribute variant. However,
28572 if the attributes are target-dependent and they differ, we need to
28573 use structural equality checks for this type.
28574 (build_qualified_type): A qualified type is not equivalent to its
28575 unqualified variant; set the canonical type appropriately.
28576 (build_distinct_type_copy): When building a distinct type from
28577 another type, the new type is its own canonical type.
28578 (build_variant_type_copy): When building a new type variant, we
28579 assume that it is equivalent to the original type.
28580 (build_pointer_type_for_mode): When building a pointer type, also
28581 build a canonical type pointer.
28582 (build_reference_type_for_mode): When building a reference type,
28583 also build a canonical type reference.
28584 (build_index_type): When we can't hash an index type (e.g.,
28585 because its maximum value is negative), the index type requires
28586 structural equality tests.
28587 (build_array_type): Build the canonical form of an array type.
28588 (build_function_type): Function types require structural equality,
28589 because they contain default arguments, attributes, etc.
28590 (build_method_type_directly): Ditto for method types.
