VEXPANDPS xmm {z}, m128
Synopsis
_mm_maskz_expandloadu_ps(__mmask8 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 zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation
m := 0
FOR j := 0 to 3
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] := 0
FI
ENDFOR
dst[MAX:128] := 0
