void deleteDeadLoop(llvm::Loop* L,
llvm::DominatorTree* DT,
llvm::ScalarEvolution* SE,
llvm::LoopInfo* LI)Description
This function deletes dead loops. The caller of this function needs to guarantee that the loop is infact dead. The function requires a bunch or prerequisites to be present: - The loop needs to be in LCSSA form - The loop needs to have a Preheader - A unique dedicated exit block must exist This also updates the relevant analysis information in \p DT, \p SE, and \p LI if pointers to those are provided. It also updates the loop PM if an updater struct is provided.
