c-parser.c (c_parser_cast_expression): Only insert casts into hash table if pointer.
PR/21391
* c-parser.c (c_parser_cast_expression): Only insert casts into
hash table if pointer.
* function.c (used_types_insert_helper): Rename from
used_types_insert.
(used_types_insert): Call used_types_insert_helper.
* function.h (used_types_insert): Accept only one argument.
* cp/typeck.c (build_static_cast_1): Save casted types in used types
hash table.
(build_reinterpret_cast_1): Same.
* cp/rtti.c (build_dynamic_cast_1): Same.
* testsuite/g++.dg/other/unused1.C: New.
