Just like in the 32-bit version of this recipe, we use the GNU Debugger (GDB) on /bin/bash in step 1, set a breakpoint at the main function, run /bin/bash within GDB up to the breakpoint, and then run a gdb command to view our registers. In step 2, we quit GDB once we're done reviewing the registers in its output and select y when prompted. Finally, in step 3, we run the lscpu command to review the capabilities of our processor. Review your own output since your processor will be different to mine.
