so what's the best way to do the equivelent of addr2line on something like this, now that we aren't allowed to know the RIP anymore? I probably knew at one point but I've spent the last 3 months doing 6502 assembly language Demoscene coding and so apparently I've forgotten everything I once knew about x86_64 kernel interfaces. (As can be imagined, Demoscene coding work is a lot more mentally rewarding than perf_fuzzer work). Vince
