Hi,

According to the comments from Tom.  I make a patch to add test for
CTF function.
This test will test both "tsave -ctf" and "target ctf" function.  You
can use following command call it:
make check RUNTESTFLAGS="--target_board=native-gdbserver ctf.exp"

Thanks,
Hui

	* gdb.trace/Makefile.in (PROGS): Add ctf.
	* gdb.trace/ctf.c: New file.
	* gdb.trace/ctf.exp: New file.
