Message-ID: <96b9fd062fd77a263e2a467461af04a3b720b6ef.1581410934.git.tankut.baris.aktemur@intel.com> (raw)

gdbserver/ChangeLog:
2020-02-10 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com>
Make process_stratum_target's read_pc and write_pc 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::read_pc): Define.
(process_target::write_pc): Define.
Update the derived structs and callers below.
* regcache.c (regcache_read_pc): Update.
(regcache_write_pc): Update.
* linux-low.c (linux_target_ops): Update.
(linux_read_pc): Turn into ...
(linux_process_target::read_pc): ... this.
(linux_write_pc): Turn into ...
(linux_process_target::write_pc): ... this.
* linux-low.h (class linux_process_target): Update.
* lynx-low.c (lynx_target_ops): Update.
* nto-low.c (nto_target_ops): Update.
* win32-low.c (win32_target_ops): Update.
