If this feature gets mature enough I'd even suggest that we make 
this the default output mode.

( Sidenote: the patched perf_evsel__add_hist_entry() function 
  seems a tad large now, it might make sense to factor out one 
  or two helper inline functions from it and thus clean up the 
  flow all around. )

Btw., assuming that you are profiling user-space applications 
via call-chains, how do you deal with the lack of dwarf decoding 
done by perf, in particular on 64-bit x86 systems where most 
distros don't compile call-chains into libraries and 
application? In what practical situations does that limitation 
hinder you and what do you do about it - rebuild your apps with 
frame pointers included?

Thanks,
