Question

我用汇编语言编写了x86-64代码。输出为17。

    .text
.LC0:
    .string "%d\n"
printint:
    pushq   %rbp
    movq    %rsp, %rbp
    subq    $16, %rsp
    movl    %edi, -4(%rbp)
    movl    -4(%rbp), %eax
    movl    %eax, %esi
    leaq    .LC0(%rip), %rdi
    movl    $0, %eax
    call    printf@PLT
    nop
    leave
    ret

    .globl  main
    .type   main, @function
main:
    pushq   %rbp
    movq    %rsp, %rbp
    movq    $2, %r8
    movq    $3, %r9
    movq    $5, %r10
    imulq   %r9, %r10
    addq    %r8, %r10
    movq    $8, %r8
    movq    $3, %r9
    movq    %r8,%rax
    cqo
    idivq   %r9
    movq    %rax,%r8
    subq    %r10, %r8
    movq    %r10, %rdi
    call    printint
    movl    $0, %eax
    popq    %rbp
    ret

当我通过GCC编译时，出现此错误。

但是当我进入https://www.onlinegdb.com/online_gcc_assembler并对其进行编译时，我得到了正确的答案（17）。

我仍在学习汇编语言。我搜索了一个答案，但找不到答案。您能解释一下原因吗？

AMD RYZEN 5处理器（基于x64）

64位Windows 10

我用汇编语言编写了x86-64代码。输出为17。 >

out.s:31: Error: 'cqo' is only supported in 64-bit mode告诉您您尝试在32位模式下汇编此64位代码。也许您尝试在Windows下使用mingw32？

此代码用于x86-64 GNU / Linux：请注意在RDI，RSI和@plt的使用中传递args的调用约定； DLL不使用PLT。这就是为什么它在使用x86-64 GNU / Linux的OnlineGDB中工作的原因。

除了在WSL中，它不能在64位Windows上运行。甚至Cygwin 64都是源兼容性层，而不是二进制/ ABI /调用约定。
