```
  /* Adjust the function return type.  */
  if (orig_rettype == void_type_node)
    return;

```

That should be:
```
  /* Adjust the function return type.  */
  if (TREE_CODE (orig_rettype) == VOID_TYPE)
    return;
```

this is in simd_clone_adjust_return_type.

simd_clone_adjust has the same bug:
```
  if (orig_rettype != void_type_node)

```
