Subject: btrace: clear thread stopped state when stopping replaying
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=add41f3be2942f5bb0477ce124167b3ff8c151d9;p=thirdparty%2Fbinutils-gdb.git

btrace: clear thread stopped state when stopping replaying

When we stop replaying a thread, it moves to the end of its execution
history.  It retains its state from when it was replaying, though, so a
subsequent 'info program' command would show wrong information.

Clear all execution state used by the 'info program' command.
