9 // BreakCriticalEdges pass - Break all of the critical edges in the CFG by
10 // inserting a dummy basic block. This pass may be "required" by passes that
11 // cannot deal with critical edges. For this usage, the structure type is
12 // forward declared. This pass obviously invalidates the CFG, but can update
13 // dominator trees.
