32194 * c-common.c (c_common_nodes_and_builtins): Since variants of
32195 void_type_node get built before it is given a name, we need to
32196 give those variants the name, too.
32197 (complete_array_type): We need to work with the canonical main
32198 type of the array, from which we will build the qualified version.

32202 * stor-layout.c (layout_type): When we don't know the
32203 alignment of a type for which we're building an array, we end up
32204 guessing wrong, so make the type require structural equality.
32205 * tree.c (make_node_stat): When we build a new type, it is its
32206 own canonical type.
32207 (build_type_attribute_qual_variant): When building an attribute
32208 variant, its canonical type is the non-attribute variant. However,
32209 if the attributes are target-dependent and they differ, we need to
32210 use structural equality checks for this type.
32211 (build_qualified_type): A qualified type is not equivalent to its
32212 unqualified variant; set the canonical type appropriately.
32213 (build_distinct_type_copy): When building a distinct type from
32214 another type, the new type is its own canonical type.
32215 (build_variant_type_copy): When building a new type variant, we
32216 assume that it is equivalent to the original type.
32217 (build_pointer_type_for_mode): When building a pointer type, also
32218 build a canonical type pointer.
32219 (build_reference_type_for_mode): When building a reference type,
32220 also build a canonical type reference.
32221 (build_index_type): When we can't hash an index type (e.g.,
32222 because its maximum value is negative), the index type requires
32223 structural equality tests.
32224 (build_array_type): Build the canonical form of an array type.
32225 (build_function_type): Function types require structural equality,
32226 because they contain default arguments, attributes, etc.
32227 (build_method_type_directly): Ditto for method types.
32228 (build_offset_type): Build the canonical offset type.
32229 (build_complex_type): Build the canonical vector type.
