12412 * c-common.c (c_common_nodes_and_builtins): Since variants of
12413 void_type_node get built before it is given a name, we need to
12414 give those variants the name, too.
12415 (complete_array_type): We need to work with the canonical main

12420 * stor-layout.c (layout_type): When we don't know the
12421 alignment of a type for which we're building an array, we end up
12422 guessing wrong, so make the type require structural equality.
12423 * tree.c (make_node_stat): When we build a new type, it is its
12424 own canonical type.
12425 (build_type_attribute_qual_variant): When building an attribute
12426 variant, its canonical type is the non-attribute variant. However,
12427 if the attributes are target-dependent and they differ, we need to
12428 use structural equality checks for this type.
12429 (build_qualified_type): A qualified type is not equivalent to its
12430 unqualified variant; set the canonical type appropriately.
12431 (build_distinct_type_copy): When building a distinct type from
12432 another type, the new type is its own canonical type.
12433 (build_variant_type_copy): When building a new type variant, we
12434 assume that it is equivalent to the original type.
12435 (build_pointer_type_for_mode): When building a pointer type, also
12436 build a canonical type pointer.
12437 (build_reference_type_for_mode): When building a reference type,
12438 also build a canonical type reference.
12439 (build_index_type): When we can't hash an index type (e.g.,
12440 because its maximum value is negative), the index type requires
12441 structural equality tests.
12442 (build_array_type): Build the canonical form of an array type.
12443 (build_function_type): Function types require structural equality,
12444 because they contain default arguments, attributes, etc.
12445 (build_method_type_directly): Ditto for method types.
12446 (build_offset_type): Build the canonical offset type.
12447 (build_complex_type): Build the canonical vector type.
