Neonint8x8x2_tvzip_s8(int8x8_t a, int8x8_t b)Vector manipulation / Zip elements
Description
Interleave two vectors. This intrinsic reads corresponding elements from the two source vectors as pairs, interleaves the pairs, and returns the resulting interleaved vector.
Results

Operation

CheckFPAdvSIMDEnabled64();
bits(datasize) operand1 = V[n];
bits(datasize) operand2 = V[m];
bits(datasize) result;

integer base = part * pairs;

for p = 0 to pairs-1
    Elem[result, 2*p+0, esize] = Elem[operand1, base+p, esize];
    Elem[result, 2*p+1, esize] = Elem[operand2, base+p, esize];

V[d] = result;
