--- Comment #2 from fxue at gcc dot gnu.org ---
For a self-recursive function, a for-all-contexts clone could generate an edge
whose callee is not the function. Thus, to check whether an edge stands for a
recursive call during cloning, we should not use ordinary way of comparing
caller and callee of the edge.
