gdbserver/ChangeLog: 2020-02-20 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> Turn process_stratum_target's supports_catch_syscall 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_catch_syscall): Update the macro. * target.cc (process_target::supports_catch_syscall): Define. Update the derived classes and callers below. * linux-low.cc (linux_target_ops): Update. (linux_supports_catch_syscall): Turn into ... (linux_process_target::supports_catch_syscall): ... 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.
