In particular it prints an entry for each objfile, even if only to say that the objfile does not have any associated frame filters. I think it's better to only print output when there is a frame filter. There's nothing worth doing with the no-frame-filter information, and limiting the output makes it much more readable. Built and regtested on x86-64 Fedora 23. 2016-06-23 Tom Tromey PR gdb/16483: * python/lib/gdb/command/frame_filters.py (InfoFrameFilter.list_frame_filters): Rename to print_list.
