Your version of gdb is very old. In case it does not have that functionality implemented, here's a gdb function I'm using to print the contents of eflags:

<pre><code>define eflags
 printf " OF &lt;%d&gt; DF &lt;%d&gt; IF &lt;%d&gt; TF &lt;%d&gt;",\
 (($eflags &gt;&gt; 0xB) &amp; 1), (($eflags &gt;&gt; 0xA) &amp; 1), \
 (($eflags &gt;&gt; 9) &amp; 1), (($eflags &gt;&gt; 8) &amp; 1)
 printf " SF &lt;%d&gt; ZF &lt;%d&gt; AF &lt;%d&gt; PF &lt;%d&gt; CF &lt;%d&gt;\n",\
 (($eflags &gt;&gt; 7) &amp; 1), (($eflags &gt;&gt; 6) &amp; 1),\
 (($eflags &gt;&gt; 4) &amp; 1), (($eflags &gt;&gt; 2) &amp; 1), ($eflags &amp; 1)
 printf " ID &lt;%d&gt; VIP &lt;%d&gt; VIF &lt;%d&gt; AC &lt;%d&gt;",\
 (($eflags &gt;&gt; 0x15) &amp; 1), (($eflags &gt;&gt; 0x14) &amp; 1), \
 (($eflags &gt;&gt; 0x13) &amp; 1), (($eflags &gt;&gt; 0x12) &amp; 1)
 printf " VM &lt;%d&gt; RF &lt;%d&gt; NT &lt;%d&gt; IOPL &lt;%d&gt;\n",\
 (($eflags &gt;&gt; 0x11) &amp; 1), (($eflags &gt;&gt; 0x10) &amp; 1),\
 (($eflags &gt;&gt; 0xE) &amp; 1), (($eflags &gt;&gt; 0xC) &amp; 3)
end
document eflags
Print EFLAGS register. (x86)
end
</code></pre>

I'm currently working with GDB and NASM for assembly programming. 

Unfortunately I am unable to see the EFlags register mnemonics (ZF, AF, PF etc...) inside GDB.

I am being shown a decimal value instead: <code>eflags 0x246 582</code>

I'm sure I could convert the decimal to binary and count the flags myself, but this seems a lot of work for a feature that every one else seems to have?

Operating System: <code>Mountain Lion 10.8.2</code>

我目前正在使用GDB和NASM进行汇编编程。不幸的是，我无法看到EFlags寄存器助记符(ZF、AF、PF等)在GDB内部。我看到的是一个十进制值：eflags         0x246 582我确信我可以将十进制数转换为二进制数，并自己计算标志数，但对于一个其他人似乎都有的功能，这似乎需要大量的工作？操作系统：Mo...
