Synopsis
_mm512_mask_expandloadu_ps(__m512 src, __mmask16 k, void const* mem_addr);
Description
Load contiguous active single-precision (32-bit) floating-point elements from unaligned memory at "mem_addr" (those with their respective bit set in mask "k"), and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
m := 0
FOR j := 0 to 15
i := j*32
IF k[j]
dst[i+31:i] := MEM[mem_addr+m+31:mem_addr+m]
m := m + 32
ELSE
dst[i+31:i] := src[i+31:i]
FI

dst[MAX:512] := 0
