title: tell gdb to disassemble "unknown" code
body: <p>is it possible to configure gdb in order to debug assembly code when there are no debug symbols or no sources available ?
  I mean showing assembly instruction by assembly instruction when performing a step by step debug (next /step commands) (not desassembling all the function. just the next instruction that will be executed)</p>
