Synopsis
_mm512_rorv_epi64(__m512i a, __m512i b);
Description
Rotate the bits in each packed 64-bit integer in "a" to the right by the number of bits specified in the corresponding element of "b", and store the results in "dst".
Operation
DEFINE RIGHT_ROTATE_QWORDS(src, count_src) {
count := count_src % 64
RETURN (src >> count) OR (src << (64 - count))
}
FOR j := 0 to 7
i := j*64
dst[i+63:i] := RIGHT_ROTATE_QWORDS(a[i+63:i], b[i+63:i])
ENDFOR
dst[MAX:512] := 0
