1910
1911         * c-common.c(c_common_nodes_and_builtins): Since variants of
1912         void_type_node get built before it is given a name, we need to
1913         give those variants the name, too.
1914         (complete_array_type): We need to work with the canonical main
1915         type of the array, from which we will build the qualified version.

1920         alignment of a type for which we're building an array, we end up

1922         * tree.c (make_node_stat): When we build a new type, it is its
1923         own canonical type.
1924         (build_type_attribute_qual_variant): When building an attribute
1925         variant, its canonical type is the non-attribute variant. However,

1927         use structural equality checks for this type.
1928         (build_qualified_type): A qualified type is not equivalent to its
1929         unqualified variant; set the canonical type appropriately.

1931         another type, the new type is its own canonical type.

1937         also build a canonical type reference.
1938         (build_index_type): When we can't hash an index type (e.g.,
1939         because its maximum value is negative), the index type requires
1940         structural equality tests.
1941         (build_array_type): Build the canonical form of an array type.
1942         (build_function_type): Function types require structural equality,

1945         (build_offset_type): Build the canonical offset type.
