2160 * c-common.c(c_common_nodes_and_builtins): Since variants of
2161 void_type_node get built before it is given a name, we need to
2162 give those variants the name, too.

2168 * stor-layout.c (layout_type): When we don't know the

2173 (build_type_attribute_qual_variant): When building an attribute
2174 variant, its canonical type is the non-attribute variant. However,
2175 if the attributes are target-dependent and they differ, we need to
2176 use structural equality checks for this type.
2177 (build_qualified_type): A qualified type is not equivalent to its
2178 unqualified variant; set the canonical type appropriately.
2179 (build_distinct_type_copy): When building a distinct type from
2180 another type, the new type is its own canonical type.
2181 (build_variant_type_copy): When building a new type variant, we
2182 assume that it is equivalent to the original type.
2183 (build_pointer_type_for_mode): When building a pointer type, also
2184 build a canonical type pointer.
2185 (build_reference_type_for_mode): When building a reference type,
2186 also build a canonical type reference.
2187 (build_index_type): When we can't hash an index type (e.g.,
2188 because its maximum value is negative), the index type requires
2189 structural equality tests.
2190 (build_array_type): Build the canonical form of an array type.
2191 (build_function_type): Function types require structural equality,
2192 because they contain default arguments, attributes, etc.
2193 (build_method_type_directly): Ditto for method types.
2194 (build_offset_type): Build the canonical offset type.
2195 (build_complex_type): Build the canonical vector type.
