Synopsis
_mm512_mask_cvt_roundph_epi64(__m512i src, __mmask8 k, __m128h a, int rounding);
Description
Convert packed half-precision (16-bit) floating-point elements in "a" to packed 64-bit integers, and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
