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.
