30812 * c-common.c (c_common_nodes_and_builtins): Since variants of
30813 void_type_node get built before it is given a name, we need to
30814 give those variants the name, too.
30815 (complete_array_type): We need to work with the canonical main

30820 * stor-layout.c (layout_type): When we don't know the
30821 alignment of a type for which we're building an array, we end up
30822 guessing wrong, so make the type require structural equality.
30823 * tree.c (make_node_stat): When we build a new type, it is its
30824 own canonical type.
30825 (build_type_attribute_qual_variant): When building an attribute
30826 variant, its canonical type is the non-attribute variant. However,
30827 if the attributes are target-dependent and they differ, we need to
30828 use structural equality checks for this type.
30829 (build_qualified_type): A qualified type is not equivalent to its
30830 unqualified variant; set the canonical type appropriately.
30831 (build_distinct_type_copy): When building a distinct type from
30832 another type, the new type is its own canonical type.
30833 (build_variant_type_copy): When building a new type variant, we
30834 assume that it is equivalent to the original type.
30835 (build_pointer_type_for_mode): When building a pointer type, also
30836 build a canonical type pointer.
30837 (build_reference_type_for_mode): When building a reference type,
30838 also build a canonical type reference.
30839 (build_index_type): When we can't hash an index type (e.g.,
30840 because its maximum value is negative), the index type requires
30841 structural equality tests.
30842 (build_array_type): Build the canonical form of an array type.
30843 (build_function_type): Function types require structural equality,
30844 because they contain default arguments, attributes, etc.
30845 (build_method_type_directly): Ditto for method types.
30846 (build_offset_type): Build the canonical offset type.
