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 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.

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
