From c0245cb999ec9692db1947240e865988a0c19c82 Mon Sep 17 00:00:00 2001 From: Tankut Baris Aktemur Date: Mon, 17 Feb 2020 16:12:01 +0100 Subject: [PATCH 1/1] gdbserver: turn target op 'supports_agent' into a method gdbserver/ChangeLog: 2020-02-20 Tankut Baris Aktemur Turn process_stratum_target's supports_agent op into a method of process_target. * target.h (struct process_stratum_target): Remove the target op. (class process_target): Add the target op. (target_supports_agent): Update the macro. * target.cc (process_target::supports_agent): Define. Update the derived classes and callers below. * linux-low.cc (linux_target_ops): Update. (linux_supports_agent): Turn into ...
