--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note the other pattern which uses logical_inverted_value where it depends on
the type does:
/* -(type)!A -> (type)A - 1. */
(simplify
(negate (convert?:s (logical_inverted_value:s @0)))
(if (INTEGRAL_TYPE_P (type)
&& TREE_CODE (type) != BOOLEAN_TYPE
&& TYPE_PRECISION (type) > 1
&& TREE_CODE (@0) == SSA_NAME
&& ssa_name_has_boolean_range (@0))
(plus (convert:type @0) { build_all_ones_cst (type); })))
But that is ok because of the check of >1 for precision. The other one dealing
with cond is a problem there.
