10635 * c-common.c (c_common_nodes_and_builtins): Since variants of
10636 void_type_node get built before it is given a name, we need to
10637 give those variants the name, too.
10638 (complete_array_type): We need to work with the canonical main

10643 * stor-layout.c (layout_type): When we don't know the
10644 alignment of a type for which we're building an array, we end up
10645 guessing wrong, so make the type require structural equality.
10646 * tree.c (make_node_stat): When we build a new type, it is its
10647 own canonical type.
10648 (build_type_attribute_qual_variant): When building an attribute
10649 variant, its canonical type is the non-attribute variant. However,
10650 if the attributes are target-dependent and they differ, we need to
10651 use structural equality checks for this type.
10652 (build_qualified_type): A qualified type is not equivalent to its
10653 unqualified variant; set the canonical type appropriately.
10654 (build_distinct_type_copy): When building a distinct type from
10655 another type, the new type is its own canonical type.
10656 (build_variant_type_copy): When building a new type variant, we
10657 assume that it is equivalent to the original type.
10658 (build_pointer_type_for_mode): When building a pointer type, also
10659 build a canonical type pointer.
10660 (build_reference_type_for_mode): When building a reference type,
10661 also build a canonical type reference.
10662 (build_index_type): When we can't hash an index type (e.g.,
10663 because its maximum value is negative), the index type requires
10664 structural equality tests.
10665 (build_array_type): Build the canonical form of an array type.
10666 (build_function_type): Function types require structural equality,
10667 because they contain default arguments, attributes, etc.
10668 (build_method_type_directly): Ditto for method types.
10669 (build_offset_type): Build the canonical offset type.
10670 (build_complex_type): Build the canonical vector type.
