title: How to break on assembly instruction at a given address in gdb?
body: <pre><code>0x0000000000400448 &lt;main+0&gt;:    push   %rbp
  0x0000000000400449 &lt;main+1&gt;:    mov    %rsp,%rbp
  0x000000000040044c &lt;main+4&gt;:    mov    $0x6,%eax
  0x0000000000400451 &lt;main+9&gt;:    leaveq 
  0x0000000000400452 &lt;main+10&gt;:   retq   
  </code></pre>
  
  <p>I tried:</p>
  
  <pre><code>breaki 0x0000000000400448
  </code></pre>
  
  <p>but it seems that there not such command.</p>
  
  <p>Does gdb have such a feature?</p>
