reportVectorization()

void llvm::LoopVectorizationUtils::reportVectorization	(	OptimizationRemarkEmitter *	ORE,
		Loop *	TheLoop,
		ElementCount	VFWidth,
		unsigned	IC )

Report successful vectorization of the loop.

In case an outer loop is vectorized, prepend "outer" to the vectorization remark.

reportVectorizationFailure() [1/2]

void llvm::LoopVectorizationUtils::reportVectorizationFailure	(	const StringRef	DebugMsg,
		const StringRef	OREMsg,
		const StringRef	ORETag,
		OptimizationRemarkEmitter *	ORE,
		const Loop *	TheLoop,
		Instruction *	I = nullptr )

Reports a vectorization failure: print DebugMsg for debugging purposes along with the corresponding optimization remark RemarkName.

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

reportVectorizationFailure() [2/2]

void llvm::LoopVectorizationUtils::reportVectorizationFailure ( const StringRef DebugMsg, const StringRef ORETag, OptimizationRemarkEmitter * ORE, const Loop * TheLoop, Instruction * I = nullptr )

inline

Same as above, but the debug message and optimization remark are identical.

reportVectorizationInfo()

void llvm::LoopVectorizationUtils::reportVectorizationInfo	(	const StringRef	Msg,
		const StringRef	ORETag,
		OptimizationRemarkEmitter *	ORE,
		const Loop *	TheLoop,
		Instruction *	I = nullptr,
		DebugLoc	DL = {} )

Reports an informative message: print Msg for debugging purposes as well as an optimization remark.

Uses either I as location of the remark, or otherwise TheLoop. If DL is passed, use it as debug location for the remark.
