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 +unconditional jump. Updating of edges is not transparent and each optimization pass is required to do so manually. However only few cases occur in practice.
