--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is one testcase that ICEs on aarch64 in the same way at `-O2
-frounding-math` since there is V4HF support there:
```
void f(_Float16*);
void
foo1 ()
{
  int t0 = 3967;
  int t1 = 3969;
  int t2 = 3971;
  int t3 = 3973;
  _Float16 tt[4];
  tt[0] = t0;
  tt[1] = t1;
  tt[2] = t2;
  tt[3] = t3;
  f(&tt[0]);
}
```

So please add this one too.
