❌ Example of incorrect code

(func (param $a i32) (param $b i32)
    (get_local $a)
    (get_local $b)
    (i32.add)
)

✅ Example of correct code

(func (param $a i32) (param $b i32)
    (i32.add (get_local $a) (get_local $b))
)

remove-unused

(module
    (func $one (result i32)
        i32.const 1
    )
    (func $oneTwo (param $y) (result i32 i32)
-       (call $one (local.get $y))
+       (call $one)
        i32.const 2
    )
