30791 * c-common.c (c_common_nodes_and_builtins): Since variants of
30792 void_type_node get built before it is given a name, we need to
30793 give those variants the name, too.

30799 * stor-layout.c (layout_type): When we don't know the
30800 alignment of a type for which we're building an array, we end up
30801 guessing wrong, so make the type require structural equality.

30803 own canonical type.
30804 (build_type_attribute_qual_variant): When building an attribute
30805 variant, its canonical type is the non-attribute variant. However,
30806 if the attributes are target-dependent and they differ, we need to
30807 use structural equality checks for this type.
30808 (build_qualified_type): A qualified type is not equivalent to its
30809 unqualified variant; set the canonical type appropriately.
30810 (build_distinct_type_copy): When building a distinct type from
30811 another type, the new type is its own canonical type.
30812 (build_variant_type_copy): When building a new type variant, we
30813 assume that it is equivalent to the original type.
30814 (build_pointer_type_for_mode): When building a pointer type, also
30815 build a canonical type pointer.
30816 (build_reference_type_for_mode): When building a reference type,
30817 also build a canonical type reference.
30818 (build_index_type): When we can't hash an index type (e.g.,
30819 because its maximum value is negative), the index type requires
30820 structural equality tests.
30821 (build_array_type): Build the canonical form of an array type.
30822 (build_function_type): Function types require structural equality,
30823 because they contain default arguments, attributes, etc.
30824 (build_method_type_directly): Ditto for method types.
