Detailed Description

Caches the results of the expensive analyses that are queried repeatedly for the same values while the vectorization trees are built and their costs are estimated.

The results may change once the vectorized code is emitted and the scalars are erased, so the cache is cleared after each successful vectorizeTree().

getPointersDiff()

std::optional< int64_t > llvm::slpvectorizer::SLPAnalysisCache::getPointersDiff	(	Type *	ElemTyA,
		Value *	PtrA,
		Type *	ElemTyB,
		Value *	PtrB,
		const DataLayout &	DL,
		ScalarEvolution &	SE,
		bool	StrictCheck = false,
		bool	CheckType = true )

Cached llvm::getPointersDiff(), a miss may require SCEV analysis.

The result for (PtrA, PtrB) also serves the query for the swapped pointers.

isGuaranteedNotToBePoison()

bool llvm::slpvectorizer::SLPAnalysisCache::isGuaranteedNotToBePoison	(	const Value *	V,
