G'Day,

Is there a trick to getting perf to probe a user-level address without
debuginfo? Eg (on Linux 4.0):

# perf probe -x /root/tick '@+0x583'
Debuginfo-analysis is not supported.
  Error: Failed to add events.

I can do this using ftrace ok, eg, "p:tick_0x583 /root/tick:0x583"
works. Thanks,

Brendan
