11075 * c-common.c (c_common_nodes_and_builtins): Since variants of
11076 void_type_node get built before it is given a name, we need to
11077 give those variants the name, too.
11078 (complete_array_type): We need to work with the canonical main
11079 type of the array, from which we will build the qualified version.

11083 * stor-layout.c (layout_type): When we don't know the
11084 alignment of a type for which we're building an array, we end up
11085 guessing wrong, so make the type require structural equality.
11086 * tree.c (make_node_stat): When we build a new type, it is its
11087 own canonical type.
11088 (build_type_attribute_qual_variant): When building an attribute
11089 variant, its canonical type is the non-attribute variant. However,
11090 if the attributes are target-dependent and they differ, we need to
11091 use structural equality checks for this type.
11092 (build_qualified_type): A qualified type is not equivalent to its
11093 unqualified variant; set the canonical type appropriately.
11094 (build_distinct_type_copy): When building a distinct type from
11095 another type, the new type is its own canonical type.
11096 (build_variant_type_copy): When building a new type variant, we
11097 assume that it is equivalent to the original type.
11098 (build_pointer_type_for_mode): When building a pointer type, also
11099 build a canonical type pointer.
11100 (build_reference_type_for_mode): When building a reference type,
11101 also build a canonical type reference.
11102 (build_index_type): When we can't hash an index type (e.g.,
11103 because its maximum value is negative), the index type requires
11104 structural equality tests.
11105 (build_array_type): Build the canonical form of an array type.
11106 (build_function_type): Function types require structural equality,
11107 because they contain default arguments, attributes, etc.
11108 (build_method_type_directly): Ditto for method types.
11109 (build_offset_type): Build the canonical offset type.
11110 (build_complex_type): Build the canonical vector type.
