The output of perf-annotate has a problem.
It is so confusing that the output is mixed with
both source code and assembly code.
IMHO, we need readable annotate view based on source code,
not mixed view. (not depending on 'objdump -S')

And to do that, we can collect actual source code per function(sym)
using addr2line() and we can handle 'struct source_code'
that contains each line of code.

In near future, it would be used for new annotate view based on
actual source code per function(sym).

I think this is just a preparation so you'd be better sending it with
your new annotate view patchset later.

I got it!
I thought it is needed to separate a big commit into several commits
so I sent this patch before including new annotate view.

But as you said, it seems like just a preparation without important point(new view).
So I'll send v2 with new annotate view !

Thanks,
