Whatever debugger you're using should have an assembly view (Visual Studio, Borland IDE, gdb, etc.). If you are not using a debugger and you merely want to see what assembly is in a program, you can use a disassembler or alternatively, run the program and attach to it with a debugger and do the dump from there. See references to <a href="http://en.wikipedia.org/wiki/Disassembler" rel="nofollow noreferrer">disassemblers</a> for information on options.

As someone else mentioned, your platform's debugger is a good starting point. For the jackhammer of all debuggers and disassemblers, take a look at <a href="http://www.hex-rays.com/idapro/" rel="noreferrer">IDA Pro.</a>

On Unix/Linux platforms (including Cygwin) you can use <code>objdump --disassemble &lt;executable&gt;</code>.

blocks|key|1347750|text|在GCC/G%2B%2B中，用-S编译。它将输出一个包含汇编代码的something.s文件。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1347751|编辑:如果您希望输出采用英特尔语法(这是IMO语法，可读性更好，大多数汇编教程都使用它)，请使用-masm=intel进行编译。|1347752|entityMap^0|B|2|T|B|0|1C|B|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|R|8|@]|D|@]|E|$]]]|I|$]]

In GCC/G++, compile with <code>-S</code>. That will output a <code>something.s</code> file with the assembly code.

Edit: If you want the output to be in Intel syntax (which is IMO, much more readable, and most assembly tutorials use it), compile with <code>-masm=intel</code>.

blocks|key|1563376|text|大多数编译器都有输出汇编清单的选项。例如，在VisualStudio中，您可以使用以下内容：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1563377|cl.exe+/FAfile.asm+file.c|code-block|syntax|javascript|1563378|不过，为了获得最佳可读性，大多数调试器都会提供将反汇编与原始源代码交错的视图，以便您可以逐行将代码与编译器的输出进行比较。|1563379|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Most compilers have an option to output an assembly listing. E.g. with VisualStudio you can use something like:

<pre><code>cl.exe /FAfile.asm file.c
</code></pre>

For best readability though, most debuggers will offer a view that interleaves the disassembly with the original source, so you can compare your code with the compiler's output line by line.

blocks|key|1348081|text|很多人已经告诉过如何用给定的编译器发出汇编代码。另一种解决方案是编译一个目标文件，并使用objdump、readelf+(在Unix上)或DUMPBIN(link+(在Windows上)等工具将其转储。您也可以转储可执行文件，但读取输出会更加困难。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1348082|这样做的优点是可以与任何编译器以相同的方式工作。|1348083|entityMap|0|LINK|mutability|MUTABLE|url|http://sourceware.org/binutils/docs-2.19/binutils/objdump.html#objdump|1|http://sourceware.org/binutils/docs-2.19/binutils/readelf.html#readelf|2|http://msdn.microsoft.com/en-us/library/756as972(VS.80%2529.aspx)^0|18|7|0|1G|7|1|25|4|2|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@$A|S|B|T|1|U]|$A|V|B|W|1|X]|$A|Y|B|Z|1|10]]|C|$]]|$1|D|3|E|5|6|7|11|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|12|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]|P|$5|I|J|K|C|$L|Q]]]]

Lots of people already told how to emit assembly code with a given compiler. Another solution is to compile an object file and dump it with a tool such <a href="http://sourceware.org/binutils/docs-2.19/binutils/objdump.html#objdump" rel="noreferrer">objdump</a>, <a href="http://sourceware.org/binutils/docs-2.19/binutils/readelf.html#readelf" rel="noreferrer">readelf</a> (on Unix) or DUMPBIN(<a href="http://msdn.microsoft.com/en-us/library/756as972(VS.80).aspx" rel="noreferrer">link</a>) (on Windows).
You can also dump an executable, but it will be more difficult to read the output.

This has the advantage of working the same way with any compiler.

On an Intel Mac OS X 10.8 (Mountain Lion) the <code>-masm=intel</code> directive didn't work. However, if you have <a href="http://en.wikipedia.org/wiki/Xcode" rel="nofollow">Xcode</a> installed, it should have installed the tool named 'otool':

<pre><code>otool code.o -tV

You have to provide the compiled object code as a parameter.
