(class process_target): Add the target ops. * target.cc (process_target::read_pc): Define. (process_target::write_pc): Define. Update the derived classes and callers below. * regcache.cc (regcache_read_pc): Update. (regcache_write_pc): Update. * linux-low.cc (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.cc (lynx_target_ops): Update. * nto-low.cc (nto_target_ops): Update. * win32-low.cc (win32_target_ops): Update. --- diff --git a/gdbserver/ChangeLog b/gdbserver/ChangeLog index 1a14953eb48..871657780ba 100644 --- a/gdbserver/ChangeLog +++ b/gdbserver/ChangeLog @@ -1,3 +1,27 @@ +2020-02-20 Tankut Baris Aktemur + + Turn process_stratum_target's read_pc and write_pc ops into + methods of process_target. + + * target.h (struct process_stratum_target): Remove the target ops. + (class process_target): Add the target ops. + * target.cc (process_target::read_pc): Define. + (process_target::write_pc): Define. + + Update the derived classes and callers below. + + * regcache.cc (regcache_read_pc): Update. + (regcache_write_pc): Update. + * linux-low.cc (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.cc (lynx_target_ops): Update. + * nto-low.cc (nto_target_ops): Update. + * win32-low.cc (win32_target_ops): Update. + 2020-02-20 Tankut Baris Aktemur Turn process_stratum_target's supports_tracepoints op into a diff --git a/gdbserver/linux-low.cc b/gdbserver/linux-low.cc index d389aab62ab..90b5fcbcdcc 100644 --- a/gdbserver/linux-low.cc +++ b/gdbserver/linux-low.cc @@ -6555,8 +6555,8 @@ linux_process_target::supports_tracepoints () return (*the_low_target.supports_tracepoints) ();
