◆ changeElementCountTo() [1/2]

LegalizeMutation llvm::LegalizeMutations::changeElementCountTo	(	unsigned	TypeIdx,
		ElementCount	EC )

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

Definition at line 57 of file LegalizeMutations.cpp.

References llvm::LLT::changeElementCount().

◆ 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.

Definition at line 46 of file LegalizeMutations.cpp.

◆ 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.
