汇编编程比高级语言(如c)花费更长的时间，更难编程，这似乎是一种主流观点。因此，出于这些原因以及更好的可移植性，似乎建议或假设用高级语言编写更好。
最近我一直在用x86汇编语言写作，我开始意识到这些原因可能都不是真的，除了可移植性。也许这更多的是一个熟悉的问题，知道如何写好汇编。我还注意到在汇编中编程与在HLL中编程有很大的不同。也许一个好的、有经验的汇编程序员可以像一个有经验的C程序员用C写程序一样轻松、快速地编写程序。
也许是因为汇编编程与hll有很大的不同，因此需要不同的思维、方法和方式，这使得对不熟悉的人编写程序看起来非常尴尬，因此给汇编编程带来了不好的名声。
如果可移植性不是问题，那么C语言比NASM这样的优秀汇编器有什么优势呢?
编辑: 我只是想指出。当你用汇编语言写作时，你不必只写指令代码。您可以使用宏、过程和您自己的约定来进行各种抽象，使程序更模块化、更可维护、更易于阅读。这就是熟悉如何编写好的汇编的原因。

我用汇编编程已经有一个月了。我经常用C写一段代码，然后把它编译成汇编来帮助我。也许我没有充分利用C编译器的优化功能，但似乎我的C asm源包含不必要的操作。所以我开始看到，一个好的C编译器胜过一个好的汇编编码器的说法并不总是正确的。
Anyways, my assembly programs are so fast. And the more I use assembly the less time it takes me to write out my code because it's really not that hard. Also the comment about assembly having poor legibility is not true. If you label your programs correctly and make comments when there is additional elaboration needed you should be all set. In fact in ways assembly is more clear to the programmer because they are seeing what is happening at the level of the processor. I don't know about other programmers but for me I like knowing what's happening, rather than things being in a sort of black box.
With that said the real advantage of compilers is that a compiler can understand patterns and relationships and then automatically code them in the appropriate locations in the source. One popular example are virtual functions in C++ which requires the compiler to optimally map function pointers. However a compiler is limited to doing what the maker of the compiler allows the compiler to do. This leads to programmers sometimes having to resort to doing bizarre things with their code , adding coding time, when they could have been done trivially with assembly.
Personally I think the marketplace heavily supports high level languages. If assembly language was the only language in existence today then their would be about 70% less people programming and who knows where our world would be, probably back in the 90's. Higher level languages appeal to a broader range of people. This allows a higher supply of programmers to build the needed infrastructure of our world. Developing nations like China and India benefit heavily from languages like Java. These countries will fast develop their IT infrastructure and people will become more interconnected. So my point is that high level languages are popular not because they produce superior code but because they help to meet demand in the world's marketplaces.

如果一个普通的生产程序有10万行代码，每一行大约有8-12条汇编指令，那就是100万条汇编指令。
即使您可以以相当快的速度手写所有这些代码(请记住，这是您必须编写的8倍代码)，如果您想更改某些功能会发生什么?从这100万条指令中理解你几周前写的东西简直是一场噩梦!没有模块，没有类，没有面向对象的设计，没有框架，什么都没有。即使是为最简单的事情编写的类似代码的数量最多也令人生畏。
此外，你不能像高级语言那样优化你的代码。例如，C语言执行了大量的优化，因为你描述了你的意图，不仅仅是你的代码，在汇编程序中你只写代码，汇编程序不能对你的代码执行任何值得注意的优化。你写的就是你得到的，相信我，你不可能可靠地优化100万条指令，你在写的时候不断地打补丁。
汇编在不同的微处理器之间是不可移植的。
你好，我是一个编译器。
I just scanned thousands of lines of code while you were reading this sentence. I browsed through millions of possibilities of optimizing a single line of yours using hundreds of different optimization techniques based on a vast amount of academic research that you would spend years getting at. I won't feel any embarrassment, not even a slight ick, when I convert a three-line loop to thousands of instructions just to make it faster. I have no shame to go to great lengths of optimization or to do the dirtiest tricks. And if you don't want me to, maybe for a day or two, I'll behave and do it the way you like. I can transform the methods I'm using whenever you want, without even changing a single line of your code. I can even show you how your code would look in assembly, on different processor architectures and different operating systems and in different assembly conventions if you'd like. Yes, all in seconds. Because, you know, I can; and you know, you can't.
附言:哦，顺便说一下，你没有使用你写的一半代码。我帮了你一个忙，把它扔了。
当你将汇编语言与比C更高级的语言(如Java、Python或Ruby)进行比较时，HLL的优势甚至更大。例如，这些语言有垃圾收集:不需要担心什么时候释放内存块，也不会因为过早释放而导致内存泄漏或错误。
我现在正在comp组织学习汇编，虽然它很有趣，但它也非常低效。你必须在脑子里记住更多的细节才能让事情顺利进行，而且写同样的东西也会慢一些。例如，c++中一个简单的6行For循环可以等于18行或更多的汇编。
就我个人而言，学习硬件层面的工作方式非常有趣，它让我对计算的工作方式有了更多的了解。
