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

PreservedAnalyses run(Function &F, FunctionAnalysisManager &AM)
A CRTP mix-in to automatically provide informational APIs needed for passes.
Definition: PassManager.h:366
A set of analyses that are preserved following a run of a transformation pass.
Definition: PassManager.h:154
A container for analyses that lazily runs them and caches their results.
This header defines various interfaces for pass management in LLVM.
