16065 * c-common.c (c_common_nodes_and_builtins): Since variants of
16066 void_type_node get built before it is given a name, we need to
16067 give those variants the name, too.
16068 (complete_array_type): We need to work with the canonical main

16073 * stor-layout.c (layout_type): When we don't know the
16074 alignment of a type for which we're building an array, we end up
16075 guessing wrong, so make the type require structural equality.
16076 * tree.c (make_node_stat): When we build a new type, it is its
16077 own canonical type.
16078 (build_type_attribute_qual_variant): When building an attribute
16079 variant, its canonical type is the non-attribute variant. However,
16080 if the attributes are target-dependent and they differ, we need to
16081 use structural equality checks for this type.
16082 (build_qualified_type): A qualified type is not equivalent to its
16083 unqualified variant; set the canonical type appropriately.
16084 (build_distinct_type_copy): When building a distinct type from
16085 another type, the new type is its own canonical type.
16086 (build_variant_type_copy): When building a new type variant, we
16087 assume that it is equivalent to the original type.
16088 (build_pointer_type_for_mode): When building a pointer type, also
16089 build a canonical type pointer.
16090 (build_reference_type_for_mode): When building a reference type,
16091 also build a canonical type reference.
16092 (build_index_type): When we can't hash an index type (e.g.,
16093 because its maximum value is negative), the index type requires
16094 structural equality tests.
16095 (build_array_type): Build the canonical form of an array type.
16096 (build_function_type): Function types require structural equality,
16097 because they contain default arguments, attributes, etc.
16098 (build_method_type_directly): Ditto for method types.
