gdbserver/ChangeLog:
2020-02-10 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com>
Make process_stratum_target's insert_point and remove_point ops
methods of process_target.
* target.h (struct process_stratum_target): Remove the target ops.
(class process_target): Add the target ops.
* target.c (process_target::insert_point): Define.
(process_target::remove_point): Define.
Update the derived structs and callers below.
* mem-break.c (set_raw_breakpoint_at): Update.
(delete_raw_breakpoint): Update.
(uninsert_raw_breakpoint): Update.
(reinsert_raw_breakpoint): Update.
* linux-low.c (linux_target_ops): Update.
(linux_insert_point): Turn into ...
(linux_process_target::insert_point): ... this.
(linux_remove_point): Turn into ...
(linux_process_target::remove_point): ... this.
* linux-low.h (class linux_process_target): Update.
* lynx-low.c (lynx_target_ops): Update.
* nto-low.c (nto_target_ops): Update.
(nto_insert_point): Turn into ...
(nto_process_target::insert_point): ... this.
(nto_remove_point): Turn into ...
(nto_process_target::remove_point): ... this.
* nto-low.h (class nto_process_target): Update.
* win32-low.c (win32_target_ops): Update.
(win32_insert_point): Turn into ...
(win32_process_target::insert_point): ... this.
(win32_remove_point): Turn into ...
(win32_process_target::remove_point): ... this.
* win32-low.h (class win32_process_target): Update.
