Please put the patterns after the initial trivial ones, for example
after
(simplify
(max @0 @1)
(switch
(if (INTEGRAL_TYPE_P (type)
&& TYPE_MAX_VALUE (type)
&& operand_equal_p (@1, TYPE_MAX_VALUE (type), OEP_ONLY_CONST))
@1)
(if (INTEGRAL_TYPE_P (type)
&& TYPE_MIN_VALUE (type)
&& operand_equal_p (@1, TYPE_MIN_VALUE (type), OEP_ONLY_CONST))
@0)))
ok with that change.
