   Typical line from objdump output looks like this:
 
-  "   0:        48 c7 84 80 78 56 34    movq   $0x12345678,0x12345678(%rax,%rax,4)"

+  "   7:        12 78 56 34 12 "
 
   There are three columns (separated with tabs):
     address: offset for a particular line
     bytes: few bytes which encode a given command
     command: textual representation of command
 
   Third column is optional (as in example above).
 
   Args:
       line: objdump line (a single one).
