Mine.


```
/* (nop_outer_cast)-(inner_cast)var -> -(outer_cast)(var)
   if var is smaller in precision.
   This is always safe for both doing the negative in signed or unsigned
   as the value for undefined will not show up.  */
(simplify
 (convert (negate:s@1 (convert:s @0)))
 (if (INTEGRAL_TYPE_P (type)
      && tree_nop_conversion_p (type, TREE_TYPE (@1))
      && TYPE_PRECISION (type) > TYPE_PRECISION (TREE_TYPE (@0)))
    (negate (convert @0))))
```

This needs a check for !BOOLEAN_TYPE here I think. boolean is the special case
