VDIVPH xmm {k}, xmm, xmm
Synopsis
_mm_mask_div_ph(__m128h src, __mmask8 k, __m128h a, __m128h b);
Description
Divide packed half-precision (16-bit) floating-point elements in "a" by packed elements in "b", and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 7
IF k[j]
dst.fp16[j] := a.fp16[j] / b.fp16[j]
ELSE
dst.fp16[j] := src.fp16[j]
FI
ENDFOR
dst[MAX:128] := 0
