Metzger, Markus T Feb. 23, 2018, 9:52 a.m. UTC
Instead of giving a message that "set record btrace" needs a sub-command, GDB
crashed.  Fix it.  A regression test comes with the next patch.

2018-02-23  Markus Metzger  <markus.t.metzger@intel.com>

gdb/
	* record-btrace.c (cmd_set_record_btrace): Print sub-commands.
