SubjectRe: [PATCH v3 00/14] perf, x86: Haswell LBR call stack support

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.
