Description

Returns the distance between the pointers \p PtrA and \p PtrB iff they are compatible and it is possible to calculate the distance between them. This is a simple API that does not depend on the analysis pass.

Declared at: llvm/include/llvm/Analysis/LoopAccessAnalysis.h:742

Parameters

llvm::Type* ElemTyA

llvm::Value* PtrA

llvm::Type* ElemTyB

llvm::Value* PtrB

const llvm::DataLayout& DL

llvm::ScalarEvolution& SE

bool StrictCheck = false

Ensure that the calculated distance matches the type-based one after all the bitcasts removal in the provided pointers.

bool CheckType = true
