◆ clampMaxNumElementsStrict()

LegalizeRuleSet & llvm::LegalizeRuleSet::clampMaxNumElementsStrict	(	unsigned	TypeIdx,
		const LLT	EltTy,

inline

Express EltTy vectors strictly using vectors with NumElts elements (or scalars when NumElts equals 1).

First pad with undef elements to nearest larger multiple of NumElts. Then perform split with all sub-instructions having the same type. Using clampMaxNumElements (non-strict) can result in leftover instruction with different type (fewer elements then NumElts or scalar). No effect if the type is not a vector.
