if statement which involves bit shifting of integers and - error or not (update )

Recently I asked in this forum , whether it is an error or not to use the following if statement which involves bit shifting of given integers x and y :

if (x<<y)

The conclusive answer for that question what that the statement as written above is not any kind of error , not a run-time error as well.

Suppose we would expand the scope of that question and rewrite the statement above to be the following one instead:

if (x<<y) x++;

in this case, would it still have no error of any kind ( including run-time error) ?
