1289 * c-common.c(c_common_nodes_and_builtins): Since variants of
1290 void_type_node get built before it is given a name, we need to
1291 give those variants the name, too.

1297 * stor-layout.c (layout_type): When we don't know the
1298 alignment of a type for which we're building an array, we end up
1299 guessing wrong, so make the type require structural equality.

1302 (build_type_attribute_qual_variant): When building an attribute
1303 variant, its canonical type is the non-attribute variant. However,
1304 if the attributes are target-dependent and they differ, we need to
1305 use structural equality checks for this type.
1306 (build_qualified_type): A qualified type is not equivalent to its
1307 unqualified variant; set the canonical type appropriately.
1308 (build_distinct_type_copy): When building a distinct type from
1309 another type, the new type is its own canonical type.
1310 (build_variant_type_copy): When building a new type variant, we
1311 assume that it is equivalent to the original type.
1312 (build_pointer_type_for_mode): When building a pointer type, also
1313 build a canonical type pointer.
1314 (build_reference_type_for_mode): When building a reference type,
1315 also build a canonical type reference.
1316 (build_index_type): When we can't hash an index type (e.g.,
1317 because its maximum value is negative), the index type requires
1318 structural equality tests.
1319 (build_array_type): Build the canonical form of an array type.
1320 (build_function_type): Function types require structural equality,
1321 because they contain default arguments, attributes, etc.
1322 (build_method_type_directly): Ditto for method types.
1323 (build_offset_type): Build the canonical offset type.
1324 (build_complex_type): Build the canonical vector type.
