x86-64 寄存器只有6个寄存器来存参数，那 C 函数为什么还能超过6个参数

#include <stdio.h>int test(int arg1, int arg2, int arg3, int arg4, int arg5, int arg6, int arg7, int arg8, int arg9, int arg10) {    return arg1 + arg2 + arg3 + arg4 + arg5 + arg6 + arg7 + arg8 + arg9 + arg10;}int main() {    printf("%d", test(1, 2, 3, 4, 5, 6, 7, 8, 9, 10));    return 0;}

000000000040052d <test>:  40052d:    55
