void DecodeVPPERMMask(
ArrayRef<uint64_t> RawMask,
const llvm::APInt& UndefElts,
SmallVectorImpl<int>& ShuffleMask)
Description
Decode a VPPERM mask from a raw array of constants such as from BUILD_VECTOR. This can only basic masks (permutes + zeros), not any of the other operations that VPPERM can perform.
