In gcc-v0 , I do random searching and combine some options and params, and gcc execution report some informative message like below

aes_key.c:158:14: optimized:  Inlined SubByte/25 into KeySchedule/10 which now has time 1139.174768 and size 140, net change of +0.
aes_key.c:144:14: optimized:  Inlined SubByte/26 into KeySchedule/10 which now has time 1106.406586 and size 140, net change of +0.
aes_key.c:145:14: optimized:  Inlined SubByte/27 into KeySchedule/10 which now has time 1073.638401 and size 140, net change of +0.
aes_key.c:146:14: optimized:  Inlined SubByte/28 into KeySchedule/10 which now has time 1040.870218 and size 140, net change of +0.
aes_key.c:147:14: optimized:  Inlined SubByte/29 into KeySchedule/10 which now has time 1008.102035 and size 140, net change of +0.
aes_key.c:156:18: optimized: basic block part vectorized using 16 byte vectors
aes.c:117:3: optimized: basic block part vectorized using 16 byte vectors

that messes up my screen, how could I suppress it?

After some tracing, get here . in env/lib/python3.10/site-packages/grpc/_channel.py:926 self._channel.segregated_call

    def _blocking(self, request, timeout, metadata, credentials, wait_for_ready,
                  compression):
        state, operations, deadline, rendezvous = self._prepare(
            request, timeout, metadata, wait_for_ready, compression)
        if state is None:
            raise rendezvous  # pylint: disable-msg=raising-bad-type
        else:
            call = self._channel.segregated_call(                  #<<<<<<
                cygrpc.PropagationConstants.GRPC_PROPAGATE_DEFAULTS,
                self._method, None, _determine_deadline(deadline), metadata,
                None if credentials is None else credentials._credentials, ((
                    operations,
                    None,
                ),), self._context)
            event = call.next_event()
            _handle_event(event, state, self._response_deserializer)
            return state, call

looks like the client env fires someting to the server, and where can I config in server side to redirect or suppress the message.
I use local mode now.
Thanks.
