gdbserver: turn target op 'supports_hardware_single_step' into a method
gdbserver/ChangeLog:
2020-02-20 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com>
Turn process_stratum_target's supports_hardware_single_step 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_hardware_single_step): Update the macro.
(target_can_do_hardware_single_step): Remove declaration.
* target.cc (process_target::supports_hardware_single_step): Define.
(target_can_do_hardware_single_step): Remove.
Update the derived classes and callers below.
* linux-low.h (class linux_process_target): Update.
* linux-low.cc (linux_target_ops): Update.
(linux_supports_hardware_single_step): Turn into ...
(linux_process_target::supports_hardware_single_step): ... this.
* lynx-low.h (class lynx_process_target): Update.
* lynx-low.cc (lynx_target_ops): Update.
(lynx_process_target::supports_hardware_single_step): Define.
* nto-low.h (class nto_process_target): Update.
* nto-low.cc (nto_target_ops): Update.
(nto_process_target::supports_hardware_single_step): Define.
* win32-low.h (class win32_process_target): Update.
* win32-low.cc (win32_target_ops): Update.
(win32_process_target::supports_hardware_single_step): Define.
