--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Another testcase this time for sstrunc:
```
void f0(long long *__restrict__  a, unsigned * __restrict__ b)
{
        int i = 0;
        for(int i = 0;i < 1024;i ++)
        {
          long long tt = a[i];
          if (tt > __INT_MAX__)
            tt = __INT_MAX__;
          if (tt < -__INT_MAX__-1)
            tt = -__INT_MAX__-1;
          b[i] = tt;
       }
}
```

LLVM is able to handle this for avx512f for x86_64 and for riscv.
