1302 * c-common.c(c_common_nodes_and_builtins): Since variants of
1303 void_type_node get built before it is given a name, we need to

1310 * stor-layout.c (layout_type): When we don't know the

1315 (build_type_attribute_qual_variant): When building an attribute
1316 variant, its canonical type is the non-attribute variant. However,
1317 if the attributes are target-dependent and they differ, we need to
1318 use structural equality checks for this type.
1319 (build_qualified_type): A qualified type is not equivalent to its
1320 unqualified variant; set the canonical type appropriately.
1321 (build_distinct_type_copy): When building a distinct type from
1322 another type, the new type is its own canonical type.
1323 (build_variant_type_copy): When building a new type variant, we
1324 assume that it is equivalent to the original type.

1327 (build_reference_type_for_mode): When building a reference type,
1328 also build a canonical type reference.
1329 (build_index_type): When we can't hash an index type (e.g.,
1330 because its maximum value is negative), the index type requires
1331 structural equality tests.
1332 (build_array_type): Build the canonical form of an array type.
1333 (build_function_type): Function types require structural equality,
1334 because they contain default arguments, attributes, etc.
1335 (build_method_type_directly): Ditto for method types.
1336 (build_offset_type): Build the canonical offset type.
1337 (build_complex_type): Build the canonical vector type.
