Subject: btrace: fix output of "set record btrace"
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b85310e1ec0419c4e1ca091cdd48f7597ebbefd3;p=binutils-gdb.git

btrace: fix output of "set record btrace"

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.

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