为什么在x86上可以运行的内嵌汇编代码在x64上不能运行？会报错。

#include <stdio.h>
int main()
{
    int a = 0, b = 0, c = 0;

    __asm
    {
        /*push eax s*/
        mov a, 1000
        mov b, 200
        mov c, 1
        /*mov eax, a
        add eax, b
        sub eax, c
        mov a, eax */
        /*pop eax*/
    }
    /*__asm mov a,1000*/

    printf("a=%d\nb=%d\nc=%d\n", a, b, c);

    return 0;
}
