c调用汇编编译错误

mengruohen

c调用汇编，编译出错，汇编看不懂呀，有哪位大神可以帮忙看一下，谢谢啦！
#include <stdio.h>
#include <string.h>
#include <stdint.h>
#include <stdlib.h>

static inline unsigned long long m_atomic64_add_return(long long int *v, long long int inc)
{
    long ret;

    asm volatile(
            "\n\tlwsync\n"
            "1: ldarx %[ret],0,%[cnt]\n"
            "add %[ret],%[inc],%[ret]\n"
            "stdcx. %[ret],0,%[cnt]\n"
            "bne- 1b\n"
            "isync\n"
            : [ret] "=&r" (ret)
            : [inc] "r" (inc), [cnt] "r" (v)
            : "cc", "memory";

    return ret;
}

void main()
{
    long long int x = 5;
    long long int y = m_atomic64_add_return(&x, 1);
    printf("x = %lld, y = %lld\n", x, y);
}


编译错误如下：
