gcc真的知道如何输出NASM程序集吗

因此，我有一个简单的C程序，它循环通过传递给main的参数，然后返回：

#include <stdio.h>

int main(int argc, char *argv[])
{
    int i;
    for(i = 0; i < argc; ++i) {
        fprintf(stdout, "%s\n", argv[i]);
    }
    return 0;
}

及

命令行上的错误包括：

让我相信这是TASM语法的是在这个链接上发布的信息：

TASM编码人员通常在NASM中遇到词汇困难，因为它 缺少TASM中广泛使用的“ptr”关键字

TASM使用以下方法：

mov al，字节ptr[ds:si]或mov ax，字ptr[ds:si]或mov eax， dword ptr[ds:si]

对于NASM，这简单地转化为：

mov al，字节[ds:si]或mov ax，字[ds:si]或mov eax，dword [ds:si]

NASM允许在许多地方使用这些大小关键字，从而为您提供 例如，以统一的方式对生成的操作码进行大量控制 示例这些都是有效的：

推送dword 123 jmp[ds:word 1234]；它们都指定了大小 偏移量jmp[ds:dword1234]；对于复杂的代码，当 接口32位和 ; 16位段

这可能会让人毛骨悚然，但重要的是要记住你 当你想要的时候，你可以拥有所有你需要的控制权

英特尔语法是指英特尔语法，而不是NASM语法。MASM和TASM语法基于Intel语法，NASM语法从Intel语法中得到启发，但不同

gcc输出的实际上是gas语法，使用英特尔语法处理单个指令（汇编指令、标签等。使用gas特定语法）

您知道任何关于gas语法的书籍或在线信息吗？另外，您知道Microsoft的cl.exe输出的汇编语法是什么吗？@MatthewHoggan:gas语法在gas手册中有描述：，但是，正如我所说，个别指令都是英特尔语法。
