30360 * c-common.c (c_common_nodes_and_builtins): Since variants of
30361 void_type_node get built before it is given a name, we need to
30362 give those variants the name, too.
30363 (complete_array_type): We need to work with the canonical main

30368 * stor-layout.c (layout_type): When we don't know the
30369 alignment of a type for which we're building an array, we end up
30370 guessing wrong, so make the type require structural equality.
30371 * tree.c (make_node_stat): When we build a new type, it is its
30372 own canonical type.
30373 (build_type_attribute_qual_variant): When building an attribute
30374 variant, its canonical type is the non-attribute variant. However,
30375 if the attributes are target-dependent and they differ, we need to
30376 use structural equality checks for this type.
30377 (build_qualified_type): A qualified type is not equivalent to its
30378 unqualified variant; set the canonical type appropriately.
30379 (build_distinct_type_copy): When building a distinct type from
30380 another type, the new type is its own canonical type.
30381 (build_variant_type_copy): When building a new type variant, we
30382 assume that it is equivalent to the original type.
30383 (build_pointer_type_for_mode): When building a pointer type, also
30384 build a canonical type pointer.
30385 (build_reference_type_for_mode): When building a reference type,
30386 also build a canonical type reference.
30387 (build_index_type): When we can't hash an index type (e.g.,
30388 because its maximum value is negative), the index type requires
30389 structural equality tests.
30390 (build_array_type): Build the canonical form of an array type.
30391 (build_function_type): Function types require structural equality,
30392 because they contain default arguments, attributes, etc.
30393 (build_method_type_directly): Ditto for method types.
