Description

Same functionality as RecursivelyDeleteTriviallyDeadInstructions, but allow instructions that are not trivially dead. These will be ignored. Returns true if any changes were made, i.e. any instructions trivially dead were found and deleted.

Parameters

SmallVectorImpl<llvm::WeakTrackingVH>& DeadInsts

const llvm::TargetLibraryInfo* TLI = nullptr

llvm::MemorySSAUpdater* MSSAU = nullptr

std::function<void(Value*)> AboutToDeleteCallback = std::function<void (llvm::Value *)>()
