Synopsis
 _mm512_mask_extracti32x8_epi32(__m256i src, __mmask8 k, __m512i a, int imm8);
Description
Extract 256 bits (composed of 8 packed 32-bit integers) from "a", selected with "imm8", and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
CASE imm8[0] OF
0: tmp[255:0] := a[255:0]
1: tmp[255:0] := a[511:256]
