9376 * c-common.c (c_common_nodes_and_builtins): Since variants of

9389 (build_type_attribute_qual_variant): When building an attribute
9390 variant, its canonical type is the non-attribute variant. However,

9402 also build a canonical type reference.
9403 (build_index_type): When we can't hash an index type (e.g.,
9404 because its maximum value is negative), the index type requires
9405 structural equality tests.
9406 (build_array_type): Build the canonical form of an array type.
9407 (build_function_type): Function types require structural equality,
9408 because they contain default arguments, attributes, etc.

9410 (build_offset_type): Build the canonical offset type.
9411 (build_complex_type): Build the canonical vector type.
