Synopsis
_mm512_i32logather_epi64(__m512i vindex, void const* base_addr, int scale);
Description
Loads 8 64-bit integer elements from memory starting at location "base_addr" at packed 32-bit integer indices stored in the lower half of "vindex" scaled by "scale" and stores them in "dst".
Operation
FOR j := 0 to 7
i := j*64
m := j*32
addr := base_addr + SignExtend64(vindex[m+31:m]) * ZeroExtend64(scale) * 8
dst[i+63:i] := MEM[addr+63:addr]
ENDFOR
dst[MAX:512] := 0
