perf report: Add a tip about source line numbers with overhead #152

Open seonyoungkims opened 8 years ago

There is a existing tip as below.

If you have debuginfo enabled, try: perf report -s sym,srcline

However this tip only describe a condition to use --sort sym,scrline options. So there is lack of explanation in the tip. I think that it would be better to add a tip that exactly explain the feature of --sort srcline.

The description is only for developers. I can't understand completely. Therefore, perf report -s sym, srcline are required more specific description for users.
