	* gdb.texinfo (Trace Files): Add "target ctf".

gdb/testsuite/

2013-04-10  Yao Qi  <yao@codesourcery.com>

	* gdb.trace/actions.exp: Save trace data to CTF.
	Change to ctf target if GDB supports, read CTF data in ctf
	target, and check the actions of tracepoints.
	* gdb.trace/while-stepping.exp: Likewise.
	* gdb.trace/report.exp: Test GDB saves trace data to CTF
	format and read CTF trace file if GDB supports.
	* gdb.trace/tstatus.exp: Save trace data to CTF.  If ctf
	target is supported, change to ctf target, read trace data and
	check output of command "tstatus".
	* gdb.trace/tsv.exp: Save trace frame to CTF.  If GDB supports,
	read CTF data by target ctf and call check_tsv.
