+// An example of thunk generation that takes the maximum number of permitted
+// passes to converge. We start with a set of branches of which all but one are
+// in range. Any thunk added to extend the range of a branch is inserted in
+// between the branches and the targets which knocks some more branches out
+// of range. At the end of 9 passes of createThunks() every branch has a
+// range extension thunk, allowing the final pass to check that no more thunks
+// are required.
+//
+// As the size of the .text section changes 9 times, the symbol sym which
+// depends on the size of .text will be updated 9 times. This test checks that
+// any iteration limit to updating symbols does not limit thunk convergence.
+// up to its pass limit without
