BTW the whole discussion is rather pointless.
We have to profile the software as it is, not as we wish it to be.
That means: small functions, often no frame pointer, all kinds of crappy code and missing information.
And then doing it all with as little overhead as possible.
I think on these metrics callstack LBR is attractive for many (but not all) cases.
