<pre>consider:
echo '0x2e 0x24 0x2e' | ~/llvm/AFL/bin/llvm-mc --disassemble
-triple=x86_64-pc-linux -show-encoding -show-inst
this gives us:
.text
andb $46, %al # encoding: [0x24,0x2e]
# <MCInst #197 AND8i8
# <MCOperand Imm:46>>
What happened to 0x2e? It is is a cs segment override prefix but gets no
mention in the disassembly.</pre>
