Synopsis
_mm512_permutex2var_ps(__m512 a, __m512i idx, __m512 b);
Description
Shuffle single-precision (32-bit) floating-point elements in "a" and "b" across lanes using the corresponding selector and index in "idx", and store the results in "dst".
Operation
FOR j := 0 to 15
i := j*32
off := idx[i+3:i]*32
dst[i+31:i] := idx[i+4] ? b[off+31:off] : a[off+31:off]
ENDFOR
dst[MAX:512] := 0
