Synopsis
_mm512_maskz_broadcast_f64x2(__mmask8 k, __m128d a);
Description
Broadcast the 2 packed double-precision (64-bit) floating-point elements from "a" to all elements of "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation
FOR j := 0 to 7
i := j*64
n := (j % 2)*64
IF k[j]
dst[i+63:i] := a[n+63:n]
ELSE
dst[i+63:i] := 0
FI
ENDFOR
dst[MAX:512] := 0
