Description

Determine the possible constant range of an integer or vector of integer value. This is intended as a cheap, non-recursive check.

Parameters

const llvm::Value* V

bool ForSigned

bool UseInstrInfo = true

llvm::AssumptionCache* AC = nullptr

const llvm::Instruction* CtxI = nullptr

const llvm::DominatorTree* DT = nullptr

unsigned int Depth = 0
