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