From 7f63b89b3a4229c2274f613111a907623853351f Mon Sep 17 00:00:00 2001 From: Tankut Baris Aktemur Date: Mon, 17 Feb 2020 16:12:02 +0100 Subject: [PATCH] gdbserver: turn target ops 'thread_name' and 'thread_handle' into methods gdbserver/ChangeLog: 2020-02-20 Tankut Baris Aktemur Turn process_stratum_target's thread_name and thread_handle ops into methods of process_target. * target.h (struct process_stratum_target): Remove the target ops. (class process_target): Add the target ops. (target_thread_name): Update the macro. (target_thread_handle): Update the macro. * target.cc (process_target::thread_name): Define. (process_target::thread_handle): Define. Update the derived classes and callers below. * linux-low.cc (linux_target_ops): Update. (linux_process_target::thread_name): Define.
