Date: Tue, 11 Feb 2020 09:03:00 -0000 [thread overview]
Message-ID: <14a1e87018551e60784b94530f50ac011f659376.1581410935.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 qxfer_libraries_svr4 op a method of
process_target.
* target.h (struct process_stratum_target): Remove the target op.
(class process_target): Add the target op. Also add
'supports_qxfer_libraries_svr4'.
* target.c (process_target::qxfer_libraries_svr4): Define.
(process_target::supports_qxfer_libraries_svr4): Define.
Update the derived structs and callers below.
* server.c (handle_qxfer_libraries_svr4): Update.
(handle_query): Update.
* linux-low.c (linux_target_ops): Update.
(linux_process_target::supports_qxfer_libraries_svr4): Define.
(linux_qxfer_libraries_svr4): Turn into ...
(linux_process_target::qxfer_libraries_svr4): ... 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.
