 // A Disassembler object is used to disassemble a block of code instruction by
 // instruction. The default implementation of the NameConverter object can be
 // overriden to modify register names or to do symbol lookup on addresses.
 //
 // The example below will disassemble a block of code and print it to stdout.
 //
 //   NameConverter converter;
 //   Disassembler d(converter);
 //   for (byte* pc = begin; pc < end;) {
 //     v8::internal::EmbeddedVector<char, 256> buffer;
 //     byte* prev_pc = pc;
 //     pc += d.InstructionDecode(buffer, pc);
 //     printf("%p    %08x      %s\n",
 //            prev_pc, *reinterpret_cast<int32_t*>(prev_pc), buffer);
 //   }
 //
 // The Disassembler class also has a convenience method to disassemble a block
 // of code into a FILE*, meaning that the above functionality could also be
 // achieved by just calling Disassembler::Disassemble(stdout, begin, end);
