Synopsis
 _mm512_mask_cvtt_roundps_epu64(__m512i src, __mmask8 k, __m256 a, int sae);
Description
Convert packed single-precision (32-bit) floating-point elements in "a" to packed unsigned 64-bit integers with truncation, and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set). [sae_note]
Operation
FOR j := 0 to 7
	i := j*64
	l := j*32
	IF k[j]
		dst[i+63:i] := Convert_FP32_To_UInt64_Truncate(a[l+31:l])
	ELSE
		dst[i+63:i] := src[i+63:i]
	FI

dst[MAX:512] := 0
