Synopsis
_mm_maskz_load_sh(__mmask8 k, void const* mem_addr);
Description
Load a half-precision (16-bit) floating-point element from memory into the lower element of "dst" using zeromask "k" (the element is zeroed out when mask bit 0 is not set), and set the upper elements of "dst" to zero.
Operation
IF k[0]
dst.fp16[0] := MEM[mem_addr].fp16[0]
ELSE
dst.fp16[0] := 0
FI
dst[MAX:16] := 0
