--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced down to just:
```
__attribute__((noipa))
int f(int *a,int *d)
{
signed char b = *a;
int c = b;
*d = c; // This store is important even if otherwise unused
if (c < 0 && (b&1))
return 1;
return 0;
}
int main()
{
unsigned char t = 0x81;
int x = t, y;
int tt = f(&x, &y);
if (!tt)
__builtin_abort();
}
```
