Excited to ses this one, but looks like I'm hitting some
issue.  All annotation starts for me like this:

                                                                                                       ▒
       │              Disassembly of section load0:                                                            ▒
       │                                                                                                       ▒
       │              ffffffff815eee80 <load0>:                                                                ◆
  9.33 │ffffffff815eee80:   data32 data32 data32 xchg %ax,%ax                                                  


which does not seem right

thanks,
jirka
