Also, the original code example had an error, the code that works properly was

```
static __attribute__((noinline,target_clones("default,avx2"))) int f2(int *p)
{
    asm volatile ("" :: "r"(p) : "memory");
    return *p;
}

__attribute__((noinline,target_clones("default,avx2"))) int g2(int *p)
{
    return f2(p);
}
```
