Browse Source 
gdbserver/ChangeLog:
2020-02-20  Tankut Baris Aktemur  <tankut.baris.aktemur@intel.com>

	Turn process_stratum_target's install_fast_tracepoint_jump_pad
	and get_min_fast_tracepoint_insn_len ops into methods of
	process_target.

	* target.h (struct process_stratum_target): Remove the target ops.
	(class process_target): Add the target ops.  Also add
	'supports_fast_tracepoints'.
	(target_supports_fast_tracepoints): Update the macro.
	(target_get_min_fast_tracepoint_insn_len): Update the macro.
	(install_fast_tracepoint_jump_pad): Update and rename the macro
	to ...
	(target_install_fast_tracepoint_jump_pad): ... this.
	* target.cc (process_target::supports_fast_tracepoints): Define.
	(process_target::install_fast_tracepoint_jump_pad): Define.
	(process_target::get_min_fast_tracepoint_insn_len): Define.

	Update the derived classes and callers below.

	* tracepoint.cc (install_fast_tracepoint): Update.
	* linux-low.cc (linux_target_ops): Update.
	(linux_process_target::supports_fast_tracepoints): Define.
	(linux_install_fast_tracepoint_jump_pad): Turn into ...
	(linux_process_target::install_fast_tracepoint_jump_pad): ... this.
	(linux_get_min_fast_tracepoint_insn_len): Turn into ...
	(linux_process_target::get_min_fast_tracepoint_insn_len): ... 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.
