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_u: for 16- and 32-bit signed integer input types
Note
All variants except 64-bit use saturation.

  • pack_u: for 16- and 32-bit signed integer input types
