Description

If the specified value is a trivially dead instruction, delete it. If that makes any of its operands trivially dead, delete them too, recursively. Return true if any instructions were deleted.

Parameters

llvm::Value* V

const llvm::TargetLibraryInfo* TLI = nullptr

llvm::MemorySSAUpdater* MSSAU = nullptr

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