performance when parsing perf's data
files and a complete access to the raw data.
You'll at least need some documentation how to use it.
Ping, any news on this feature? I'd welcome the ability to create native
scripts to write efficient tools based on perf.

I'll send a working solution based on Jiri's fix later when I'm back home. In
the meantime, please have a look at my other patch regarding `perf inject`
merging of trace events for sys_enter/exit.

sure you compile your code with `-g -O2` or similar.

Again, why don't you align this with the other non-inlined frames, and honor
the grouping setting? Check whether we group by address (then display file/
line), or by function (then display the function name).

The 't' key support should be a separate patch, I guess. It also does not

Right now, we only see the self cost that is directly within main, I suspect.
For C++ this is usually very misleading, and basically makes the annotate view
completely useless for application-level profiling. If a second column would
