2186 * c-common.c(c_common_nodes_and_builtins): Since variants of
2187 void_type_node get built before it is given a name, we need to
2188 give those variants the name, too.
2189 (complete_array_type): We need to work with the canonical main

2194 * stor-layout.c (layout_type): When we don't know the
2195 alignment of a type for which we're building an array, we end up
2196 guessing wrong, so make the type require structural equality.

2199 (build_type_attribute_qual_variant): When building an attribute
2200 variant, its canonical type is the non-attribute variant. However,
2201 if the attributes are target-dependent and they differ, we need to
2202 use structural equality checks for this type.
2203 (build_qualified_type): A qualified type is not equivalent to its
2204 unqualified variant; set the canonical type appropriately.
2205 (build_distinct_type_copy): When building a distinct type from
2206 another type, the new type is its own canonical type.
2207 (build_variant_type_copy): When building a new type variant, we
2208 assume that it is equivalent to the original type.
2209 (build_pointer_type_for_mode): When building a pointer type, also
2210 build a canonical type pointer.
2211 (build_reference_type_for_mode): When building a reference type,
2212 also build a canonical type reference.
2213 (build_index_type): When we can't hash an index type (e.g.,
2214 because its maximum value is negative), the index type requires
2215 structural equality tests.
2216 (build_array_type): Build the canonical form of an array type.
2217 (build_function_type): Function types require structural equality,
2218 because they contain default arguments, attributes, etc.
2219 (build_method_type_directly): Ditto for method types.
2220 (build_offset_type): Build the canonical offset type.
2221 (build_complex_type): Build the canonical vector type.
