From 93fe88b24c7e644e7b0947256bb32c2139d8afe5 Mon Sep 17 00:00:00 2001 From: Tankut Baris Aktemur Date: Mon, 17 Feb 2020 16:11:55 +0100 Subject: [PATCH] gdbserver: turn target op '{supports_}stopped_by_hw_breakpoint' into a method gdbserver/ChangeLog: 2020-02-20 Tankut Baris Aktemur Turn process_stratum_target's {supports_}stopped_by_hw_breakpoint ops into methods of process_target. * target.h (struct process_stratum_target): Remove the target ops. (class process_target): Add the target ops. (target_stopped_by_hw_breakpoint): Update the macro. (target_supports_stopped_by_hw_breakpoint): Update the macro. * target.cc (process_target::stopped_by_hw_breakpoint): Define. (process_target::supports_stopped_by_hw_breakpoint): Define. Update the derived classes and callers below. * linux-low.cc (linux_target_ops): Update. (linux_stopped_by_hw_breakpoint): Turn into ... (linux_process_target::stopped_by_hw_breakpoint): ... this. (linux_supports_stopped_by_hw_breakpoint): Turn into ... (linux_process_target::supports_stopped_by_hw_breakpoint): ... this. * linux-low.h (class linux_process_target): Update. * lynx-low.cc (lynx_target_ops): Update. * nto-low.cc (nto_target_ops): Update. * win32-low.cc (win32_target_ops): Update. --- gdbserver/ChangeLog | 24 ++++++++++++++++++++++++ gdbserver/linux-low.cc | 14 ++++++-------- gdbserver/linux-low.h | 4 ++++ gdbserver/lynx-low.cc | 2 -- gdbserver/nto-low.cc | 2 -- gdbserver/target.cc | 12 ++++++++++++ gdbserver/target.h | 20 +++++++++----------- gdbserver/win32-low.cc | 2 -- 8 files changed, 55 insertions(+), 25 deletions(-) diff --git a/gdbserver/ChangeLog b/gdbserver/ChangeLog index 55063df6a87..a2f3fceed79 100644 --- a/gdbserver/ChangeLog +++ b/gdbserver/ChangeLog @@ -1,3 +1,27 @@ +2020-02-20 Tankut Baris Aktemur + + Turn process_stratum_target's {supports_}stopped_by_hw_breakpoint + ops into methods of process_target. + + * target.h (struct process_stratum_target): Remove the target ops. + (class process_target): Add the target ops. + (target_stopped_by_hw_breakpoint): Update the macro. + (target_supports_stopped_by_hw_breakpoint): Update the macro. + * target.cc (process_target::stopped_by_hw_breakpoint): Define. + (process_target::supports_stopped_by_hw_breakpoint): Define. + + Update the derived classes and callers below. + + * linux-low.cc (linux_target_ops): Update. + (linux_stopped_by_hw_breakpoint): Turn into ... + (linux_process_target::stopped_by_hw_breakpoint): ... this. + (linux_supports_stopped_by_hw_breakpoint): Turn into ... + (linux_process_target::supports_stopped_by_hw_breakpoint): ... this. + * linux-low.h (class linux_process_target): Update. + * lynx-low.cc (lynx_target_ops): Update. + * nto-low.cc (nto_target_ops): Update. + * win32-low.cc (win32_target_ops): Update. + 2020-02-20 Tankut Baris Aktemur Turn process_stratum_target's {supports_}stopped_by_sw_breakpoint diff --git a/gdbserver/linux-low.cc b/gdbserver/linux-low.cc index b1cba91344d..9ad5e19207a 100644 --- a/gdbserver/linux-low.cc +++ b/gdbserver/linux-low.cc @@ -6010,22 +6010,22 @@ linux_process_target::supports_stopped_by_sw_breakpoint () return USE_SIGTRAP_SIGINFO;
