Please add a space between ){

Note that here you are testing for L not NULL...

> +      if (!L->isLoopSimplifyForm())
> +        INVALID(SimpleLoop, "Loop not in simplify form is invalid!");

> +      for (pred_iterator PI = pred_begin(entry), PE = pred_end(entry); PI != PE;
> +           ++PI) {
> +        // Region entering edges come from the same loop but outside the region
> +        // are not allowed.
> +        if (L && L->contains(*PI) && !R.contains(*PI))

... and here you are testing whether L is not NULL again: please
remove this check here, as this is inside a loop.
