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,
Ingo
