3056 * c-common.c(c_common_nodes_and_builtins): Since variants of
3057 void_type_node get built before it is given a name, we need to

3069 (build_type_attribute_qual_variant): When building an attribute
3070 variant, its canonical type is the non-attribute variant. However,
3071 if the attributes are target-dependent and they differ, we need to
3072 use structural equality checks for this type.
3073 (build_qualified_type): A qualified type is not equivalent to its
3074 unqualified variant; set the canonical type appropriately.
3075 (build_distinct_type_copy): When building a distinct type from
3076 another type, the new type is its own canonical type.
3077 (build_variant_type_copy): When building a new type variant, we

3081 (build_reference_type_for_mode): When building a reference type,
3082 also build a canonical type reference.
3083 (build_index_type): When we can't hash an index type (e.g.,
3084 because its maximum value is negative), the index type requires
3085 structural equality tests.
3086 (build_array_type): Build the canonical form of an array type.
3087 (build_function_type): Function types require structural equality,
3088 because they contain default arguments, attributes, etc.
3089 (build_method_type_directly): Ditto for method types.
3090 (build_offset_type): Build the canonical offset type.
3091 (build_complex_type): Build the canonical vector type.
