- Adds unary Reverse shuffles (swizzles): S32x2Reverse, S16x4Reverse,
S16x2Reverse, S8x8Reverse, S8x4Reverse, S8x2Reverse. Reversals are
done within the sub-vectors that prefix the opcode name, e.g. S8x2
reverses the 8 consecutive pairs in an S8x16 vector.
- Adds binary Zip (interleave) left and right half-shuffles to return a
single vector: S32x4ZipLeft, S32x4ZipRightS16x8ZipLeft, S16x8ZipRight,
S8x16ZipLeft, S8x16ZipRight.
- Adds binary Unzip (de-interleave) left and right half shuffles to return
a single vector: S32x4UnzipLeft, S32x4UnzipRight, S16x8UnzipLeft,
S16x8UnzipRight, S8x16UnzipLeft, S8x16UnzipRight.
- Adds binary Transpose left and right half shuffles to return
a single vector: S32x4TransposeLeft, S32x4TransposeRight,
S16x8TransposeLeft, S16xTransposeRight, S8x16TransposeLeft,
S8x16TransposeRight.
- Adds binary Concat (concatenate) byte shuffle: S8x16Concat #bytes to
paste two vectors together.
