From a2b2297a204898fa273a825d82385ce1b48941e3 Mon Sep 17 00:00:00 2001 From: Tankut Baris Aktemur Date: Mon, 17 Feb 2020 16:11:54 +0100 Subject: [PATCH] gdbserver: turn target op 'supports_z_point_type' into a method gdbserver/ChangeLog: 2020-02-20 Tankut Baris Aktemur Turn process_stratum_target's supports_z_point_type 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.cc (process_target::supports_z_point_type): Define. Update the derived classes and callers below. * mem-break.cc (z_type_supported): Update. * linux-low.cc (linux_target_ops): Update. (linux_supports_z_point_type): Turn into ...
