Declared at: llvm/include/llvm/Transforms/Utils/LoopUtils.h:518

Member Variables

public SmallVector<llvm::Instruction*> InstToDuplicate

Instructions that need to be duplicated and checked for the unswitching condition.

public llvm::Constant* KnownValue = nullptr

Constant to indicate for which value the condition is invariant.

public bool PathIsNoop = true

True if the partially invariant path is no-op (=does not have any side-effects and no loop value is used outside the loop).

public llvm::BasicBlock* ExitForPath = nullptr

If the partially invariant path reaches a single exit block, ExitForPath is set to that block. Otherwise it is nullptr.
