4799 * c-common.c (c_common_nodes_and_builtins): Since variants of
4800 void_type_node get built before it is given a name, we need to

4807 * stor-layout.c (layout_type): When we don't know the

4812 (build_type_attribute_qual_variant): When building an attribute
4813 variant, its canonical type is the non-attribute variant. However,
4814 if the attributes are target-dependent and they differ, we need to
4815 use structural equality checks for this type.
4816 (build_qualified_type): A qualified type is not equivalent to its
4817 unqualified variant; set the canonical type appropriately.
4818 (build_distinct_type_copy): When building a distinct type from
4819 another type, the new type is its own canonical type.
4820 (build_variant_type_copy): When building a new type variant, we
4821 assume that it is equivalent to the original type.

4824 (build_reference_type_for_mode): When building a reference type,
4825 also build a canonical type reference.
4826 (build_index_type): When we can't hash an index type (e.g.,
4827 because its maximum value is negative), the index type requires
4828 structural equality tests.
4829 (build_array_type): Build the canonical form of an array type.
4830 (build_function_type): Function types require structural equality,
4831 because they contain default arguments, attributes, etc.
4832 (build_method_type_directly): Ditto for method types.
4833 (build_offset_type): Build the canonical offset type.
4834 (build_complex_type): Build the canonical vector type.
