Synopsis
_mm512_mask_cvtt_roundpd_epu64(__m512i src, __mmask8 k, __m512d a, int sae);
Description
Convert packed double-precision (64-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
IF k[j]
dst[i+63:i] := Convert_FP64_To_UInt64_Truncate(a[i+63:i])
ELSE
dst[i+63:i] := src[i+63:i]
FI
ENDFOR
dst[MAX:512] := 0
