与高级语言相比，ASM的易读性很差，而且实际上难以维护。

此外，ASM开发人员比其他更流行的语言(如C)要少得多。

此外，如果您使用高级语言，并且有新的ASM指令可用(例如SSE)，您只需要更新您的编译器，您的旧代码就可以轻松使用新的指令。

如果下一个CPU有两倍多的寄存器呢?

这个问题的反义词是:编译器提供了什么功能?

我怀疑你能够/想要/应该比gcc -O3更好地优化你的ASM。

为什么?简单。

比较一下:

        for (var i = 1; i <= 100; i++)
        {
            if (i % 3 == 0)
                Console.Write("Fizz");
            if (i % 5 == 0)
                Console.Write("Buzz");
            if (i % 3 != 0 && i % 5 != 0)
                Console.Write(i);
            Console.WriteLine();
        }

with

.locals init (
    [0] int32 i)
L_0000: ldc.i4.1 
L_0001: stloc.0 
L_0002: br.s L_003b
L_0004: ldloc.0 
L_0005: ldc.i4.3 
L_0006: rem 
L_0007: brtrue.s L_0013
L_0009: ldstr "Fizz"
L_000e: call void [mscorlib]System.Console::Write(string)
L_0013: ldloc.0 
L_0014: ldc.i4.5 
L_0015: rem 
L_0016: brtrue.s L_0022
L_0018: ldstr "Buzz"
L_001d: call void [mscorlib]System.Console::Write(string)

L_0028: ldc.i4.5

L_002a: brfalse.s L_0032
L_002c: ldloc.0 
L_002d: call void [mscorlib]System.Console::Write(int32)
L_0032: call void [mscorlib]System.Console::WriteLine()
L_0037: ldloc.0 
L_0038: ldc.i4.1 
L_0039: add 
L_003a: stloc.0

它们在功能上是相同的。 第二个甚至不是汇编程序，而是。net IL(中间语言，类似于Java的字节码)。第二次编译将IL转换为本地代码(即几乎是汇编程序)，使其更加神秘。

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.

我喜欢用汇编语言编程，但是用高级语言做同样的事情需要更多的代码，而且代码行和错误之间有直接的联系。(这在几十年前的《人月神话》中就有解释。)

可以把C语言看作是“高级汇编”，但再往上走几步，你就进入了另一个世界。在c#中，你不需要三思就可以写这样的代码:

foreach (string s in listOfStrings) { /* do stuff */ }

这将是几十行，甚至几百行的汇编代码，每个实现它的程序员将采用不同的方法，下一个来的人将不得不找出它。因此，如果您相信(许多人都相信)程序主要是为其他人阅读而编写的，那么汇编的可读性就不如典型的HLL。

编辑:我积累了一个用于常见任务的个人代码库，以及用于实现类c控制结构的宏。但在90年代，当gui成为常态时，我遇到了瓶颈。太多的时间被花在了例行公事上。

我的上一个需要使用ASM的任务是在几年前，编写代码来对抗恶意软件。没有用户界面，所以只有有趣的部分，没有臃肿的部分。
