2144 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
2146 * c-common.c(c_common_nodes_and_builtins): Since variants of
2147 void_type_node get built before it is given a name, we need to
2148 give those variants the name, too.
2149 (complete_array_type): We need to work with the canonical main
2150 type of the array, from which we will build the qualified version.

2154 * stor-layout.c (layout_type): When we don't know the
2155 alignment of a type for which we're building an array, we end up
2156 guessing wrong, so make the type require structural equality.

2159 (build_type_attribute_qual_variant): When building an attribute
2160 variant, its canonical type is the non-attribute variant. However,
2161 if the attributes are target-dependent and they differ, we need to
2162 use structural equality checks for this type.
2163 (build_qualified_type): A qualified type is not equivalent to its
2164 unqualified variant; set the canonical type appropriately.
2165 (build_distinct_type_copy): When building a distinct type from
2166 another type, the new type is its own canonical type.
2167 (build_variant_type_copy): When building a new type variant, we
2168 assume that it is equivalent to the original type.
2169 (build_pointer_type_for_mode): When building a pointer type, also
2170 build a canonical type pointer.
2171 (build_reference_type_for_mode): When building a reference type,
2172 also build a canonical type reference.
2173 (build_index_type): When we can't hash an index type (e.g.,
2174 because its maximum value is negative), the index type requires
2175 structural equality tests.
2176 (build_array_type): Build the canonical form of an array type.
2177 (build_function_type): Function types require structural equality,
2178 because they contain default arguments, attributes, etc.
2179 (build_method_type_directly): Ditto for method types.
2180 (build_offset_type): Build the canonical offset type.
2181 (build_complex_type): Build the canonical vector type.
