canVectorize()

const LegalityResult & llvm::sandboxir::LegalityAnalysis::canVectorize	(	ArrayRef< Value * >	Bndl,
		bool	SkipScheduling = false
	)

Checks if it's legal to vectorize the instructions in Bndl.

\Returns a LegalityResult object owned by LegalityAnalysis. SkipScheduling skips the scheduler check and is only meant for testing.
