464 * c-common.c(c_common_nodes_and_builtins): Since variants of
465 void_type_node get built before it is given a name, we need to
466 give those variants the name, too.

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

477 (build_type_attribute_qual_variant): When building an attribute
478 variant, its canonical type is the non-attribute variant. However,
479 if the attributes are target-dependent and they differ, we need to
480 use structural equality checks for this type.
481 (build_qualified_type): A qualified type is not equivalent to its
482 unqualified variant; set the canonical type appropriately.
483 (build_distinct_type_copy): When building a distinct type from
484 another type, the new type is its own canonical type.
485 (build_variant_type_copy): When building a new type variant, we
486 assume that it is equivalent to the original type.

490 also build a canonical type reference.
491 (build_index_type): When we can't hash an index type (e.g.,
492 because its maximum value is negative), the index type requires
493 structural equality tests.
494 (build_array_type): Build the canonical form of an array type.
495 (build_function_type): Function types require structural equality,
496 because they contain default arguments, attributes, etc.
497 (build_method_type_directly): Ditto for method types.
498 (build_offset_type): Build the canonical offset type.
499 (build_complex_type): Build the canonical vector type.
