Pack
Pack values from two vectors to one Return vector type have twice more elements than input vector types. Variant with u suffix also converts to corresponding unsigned type. pack: for 16-, 32- and 64-bit integer input types pack_u: for 16- and 32-bit signed integer input types Note All variants except 64-bit use saturation.

Pack with rounding shift
Pack values from two vectors to one with rounding shift Values from the input vectors will be shifted right by n bits with rounding, converted to narrower type and returned in the result vector. Variant with u suffix converts to unsigned type. pack: for 16-, 32- and 64-bit integer input types pack_u: for 16- and 32-bit signed integer input types Note All variants except 64-bit use saturation.

Pack and store
Store values from the input vector into memory with pack Values will be stored into memory with conversion to narrower type. Variant with u suffix converts to corresponding unsigned type. pack: for 16-, 32- and 64-bit integer input types pack_u: for 16- and 32-bit signed integer input types Note All variants except 64-bit use saturation.
