changeElementCountTo() [1/2]

LegalizeMutation llvm::LegalizeMutations::changeElementCountTo	(	unsigned	TypeIdx,
		LLT	Ty
	)

Keep the same scalar or element type as TypeIdx, but take the number of elements from Ty.

changeElementCountTo() [2/2]

LegalizeMutation llvm::LegalizeMutations::changeElementCountTo	(	unsigned	TypeIdx,
		unsigned	FromTypeIdx
	)

Keep the same scalar or element type as TypeIdx, but take the number of elements from FromTypeIdx.

changeElementSizeTo()

LegalizeMutation llvm::LegalizeMutations::changeElementSizeTo	(	unsigned	TypeIdx,
		unsigned	FromTypeIdx
	)

Change the scalar size or element size to have the same scalar size as type index FromIndex.

Unlike changeElementTo, this discards pointer types and only changes the size.
