Is this going to be usable for userland call-graphs as well? If one
converts dwarf to that, I mean? Because right now with perf dwarf is
often the only thing that works properly through libc, as libc isn't
compiled with fps and has hardcoded asm not preserving fp. lbr isn't
available for many events, and often not at all available in VMs etc.

Regards,

Andres
