Hi,
uprobe_event only supports %REG arguments. I think that memory fetch, return value fetch, memory dereference functions in kernel/trace/trace_probe.c are good for uprobe_event. So with a little modification of parse_probe_arg(), uprobe_event can support @ADDR, $retval, offs(FETCHARGS) except @SYM, $stack, $stackN. Is it right?
Thanks, Hyeoncheol
