Subject: Check for listeners in emit_exiting_event
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9d741cbedb8a7a77bb7c99bbbc363d5af4ba62c2;p=binutils-gdb.git

Check for listeners in emit_exiting_event

I noticed that emit_exiting_event does not check whether there are any
listeners before creating the event object.  All other event emitters
do this, so this patch updates this one as well.
