Synopsis
_mm512_i64gather_epi32lo(__m512i vindex, void const * base_addr, int scale);
Description
Loads 8 32-bit integer memory locations starting at location "base_addr" at packed 64-bit integer indices stored in "vindex" scaled by "scale" to "dst".
Operation
FOR j := 0 to 7
i := j*32
m := j*64
addr := base_addr + vindex[m+63:m] * ZeroExtend64(scale) * 8
dst[i+31:i] := MEM[addr+31:addr]
ENDFOR
dst[MAX:256] := 0
