+ FIXME: This function should not be used to get a PBB in the STMT
+ loop in order to find out the iteration domain of the loop: the
+ counter example from Tobias is:
+
+ | for (i = 0; i < 100; i++)
+ | {
+ | if (i == 0)
+ | S1;
+ | S2;
+ | }
+
+ This function would return S1 whose iteration domain contains only
+ one point "i = 0", whereas the iteration domain of S2 has 100 points.
+
+ This should be implemented using some functionality existing in
+ CLooG-ISL. */
