This is better version, it replaces the current min_value/max_value even:
(match min_value
 uniform_integer_cst_p
 (with { tree int_cst =3D uniform_integer_cst_p (t); }
  (if ((INTEGRAL_TYPE_P (TREE_TYPE (int_cst))
        || POINTER_TYPE_P (TREE_TYPE (int_cst)))
       && wi::eq_p (wi::to_wide (int_cst),
                    wi::min_value (TREE_TYPE (int_cst))))
 )
)

(match max_value
 uniform_integer_cst_p
 (with { tree int_cst =3D uniform_integer_cst_p (t); }
  (if ((INTEGRAL_TYPE_P (TREE_TYPE (int_cst))
        || POINTER_TYPE_P (TREE_TYPE (int_cst)))
       && wi::eq_p (wi::to_wide (int_cst),
                    wi::max_value (TREE_TYPE (int_cst))))
 )
)

That is INTEGER_CST replace with uniform_integer_cst_p and type with TREE_T=
YPE
(int_cst) and t with int_cst.=
