Exception handling edges represent possible control transfers from a
trapping instruction to an exception handler. The definition of
``trapping'' varies. In C++, only function calls can throw, but for
Java and Ada, exceptions like division by zero or segmentation fault are
Ada exceptions like division by zero or segmentation fault are

Usually a code manipulating pass simplifies the instruction stream and
the flow of control, possibly eliminating some edges. This may for
example happen when a conditional jump is replaced with an
unconditional jump, but also when simplifying possibly trapping
instruction to non-trapping while compiling Java. Updating of edges

is not transparent and each optimization pass is required to do so
manually. However only few cases occur in practice. The pass may
