◆ createLVAnalysis()

OptimizationRemarkAnalysis createLVAnalysis	(	StringRef	RemarkName,
		const Loop *	TheLoop,
		Instruction *	I,
		DebugLoc	DL = {} )

static

Create an analysis remark that explains why vectorization failed RemarkName is the identifier for the remark.

If I is passed it is an instruction that prevents vectorization. Otherwise TheLoop is used for the location of the remark. If DL is passed, use it as debug location for the remark.
