title: Show current assembly instruction in GDB
body: <p>I'm doing some assembly-level debugging in GDB. Is there a way to get GDB to show me the current assembly instruction in the same way that it shows the current source line? The default output after every command looks like this:</p>
  
  <pre><code>0x0001433f      990         Foo::bar(p);
  </code></pre>
  
  <p>This gives me the address of the current instruction, but I have to keep referring back to the output of <code>disassemble</code> in order to see which instruction I'm currently executing.</p>
