2020-02-10 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com>
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.
