Ack. I just updated it.
uftrace provides mulitiple ways for user space function tracing, but it might be confusing to users suggesting all the options in README.md. We better inform a few options including -pg, -finstrument-functions and -fpatchable-function-entry=N. Signed-off-by: Honggyu Kim <honggyu.kp@gmail.com>
