9310 * c-common.c (c_common_nodes_and_builtins): Since variants of
9311 void_type_node get built before it is given a name, we need to

9323 (build_type_attribute_qual_variant): When building an attribute
9324 variant, its canonical type is the non-attribute variant. However,
9325 if the attributes are target-dependent and they differ, we need to
9326 use structural equality checks for this type.
9327 (build_qualified_type): A qualified type is not equivalent to its
9328 unqualified variant; set the canonical type appropriately.
9329 (build_distinct_type_copy): When building a distinct type from
9330 another type, the new type is its own canonical type.
9331 (build_variant_type_copy): When building a new type variant, we
9332 assume that it is equivalent to the original type.

9335 (build_reference_type_for_mode): When building a reference type,
9336 also build a canonical type reference.
9337 (build_index_type): When we can't hash an index type (e.g.,
9338 because its maximum value is negative), the index type requires
9339 structural equality tests.
9340 (build_array_type): Build the canonical form of an array type.
9341 (build_function_type): Function types require structural equality,
9342 because they contain default arguments, attributes, etc.
9343 (build_method_type_directly): Ditto for method types.
9344 (build_offset_type): Build the canonical offset type.
9345 (build_complex_type): Build the canonical vector type.
