GDB: How to remove a variable from the auto display
<p>I stumbled upon the auto-display functionality of gdb, which is pretty powerful and convenient. After calling</p>

<pre><code>(gdb) display/i $pc
(gdb) display $rax
</code></pre>

<p>the watched values are displayed automatically after every step: </p>

<pre><code>(gdb) si
0x0804805e in print_loop_start ()
2: $rax = 0
1: x/i $pc
=&gt; 0x804805e &lt;print_loop_start+6&gt;:  mov    0x4(%ebp,%eax,4),%ecx
</code></pre>

<p>But how can I "unwatch" the value in $rax, if it is no longer of interest?</p>
