-/* Problem originally visible on ia64.
-
-   There is a partial redundancy of "in + 1" that makes GCSE want to
-   transform the final while loop to 
-
-     p = in + 1;
-     tmp = p;
-     ...
-     goto start;
-   top:
-     tmp = tmp + 1;
-   start:
-     in = tmp;
-     if (in < p) goto top;
-
-   We miscalculate the number of loop iterations as (p - tmp) = 0
-   instead of (p - in) = 1, which results in overflow in the doloop
-   optimization.  */
