// 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
