Subject: [PATCH 25/58] gdbserver: turn target op 'get_tls_address' into a method
Date: Tue, 11 Feb 2020 09:03:00 -0000 [thread overview]
Message-ID: <58edb2e18b9958fc868a67b12dc6c4898e29674f.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 get_tls_address 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_get_tls_address'.
* target.c (process_target::get_tls_address): Define.
(process_target::supports_get_tls_address): Define.
Update the derived structs and callers below.
* server.c (handle_query): Update.
* linux-low.c (linux_target_ops): Update.
(linux_process_target::supports_get_tls_address): Define.
(linux_process_target::get_tls_address): Define.
* 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.
