<ul>
<li>
Instruction length varies. Hexagon has sub-insturctions, duplex, packets.

<li>
Determine length of an arbitrary insturction using page fault.

<li>
Cover all kinds of instructions includes kernel, hypervisor, or system
  management code. Using esceptions.

<li>
Using #UD to filter out undefined opcode.

<li>
Protect processor state while fuzzing. We dont want it to crash. Hook
  exeception handler to restore fuzzer to a good state. Make all register 0.

<li>
Using a dissassembler to find anomalies

</ul>
