This patch adds the generic remote bits to gdbserver so it can check for memory tagging support and handle fetch tags and store tags requests. gdbserver/ChangeLog: YYYY-MM-DD Luis Machado <luis.machado@linaro.org> * remote-utils.cc (decode_m_packet_params): Renamed from ... (decode_m_packet): ... this, which now calls decode_m_packet_params. (decode_M_packet): Use decode_m_packet_params. * remote-utils.h (decode_m_packet_params): New prototype. * server.cc (create_fmemtags_reply, parse_smemtags_request): New functions. (handle_general_set): Handle the QMemTags packet. (parse_fmemtags_request): New function. (handle_query): Handle the qMemTags packet and advertise memory tagging support. (captured_main): Initialize memory tagging flag. * server.h (struct client_state): Initialize memory tagging flag. * target.cc (process_stratum_target::supports_memory_tagging) (process_stratum_target::fetch_memtags) (process_stratum_target::store_memtags): New methods. * target.h: Include gdbsupport/byte-vector.h. (class process_stratum_target) <supports_memory_tagging> <fetch_memtags, store_memtags>: New class virtual methods. (target_supports_memory_tagging): Define.
