+ // TODO: This is not an optimal way to do this. In particular, this always
+ // inserts setjmp calls into the entries of functions with invoke instructions
+ // even though there are possibly paths through the function that do not
+ // execute any invokes. In particular, for functions with early exits, e.g.
+ // the 'addMove' method in hexxagon, it would be nice to not have to do the
+ // setjmp stuff on the early exit path. This requires a bit of dataflow, but
+ // would not be too hard to do.
// If we have an invoke instruction, insert a setjmp that dominates all
// invokes. After the setjmp, use a cond branch that goes to the original
