Hmm.. okay.  Let me think about the --no-hists flags then.

What do you want to do if the --no-hists flags is used without folded
callchain mode or other than --stdio?

And if you want to print other info in the callchains, what would be
the output of non-folded mode?

I think the simplest solution would be supporting the folded mode only
and error out other cases.  Is it ok to you?

Thanks,
