Synopsis
 _mm512_i32loextgather_epi64(__m512i vindex, void const * base_addr, _MM_UPCONV_EPI64_ENUM conv, int scale, int hint);
Description
Up-converts 8 double-precision (64-bit) memory locations starting at location "base_addr" at packed 32-bit integer indices stored in the lower half of "vindex" scaled by "scale" using "conv" to 64-bit integer elements 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
	
	CASE conv OF
	_MM_UPCONV_EPI64_NONE: dst[i+63:i] := MEM[addr+63:addr]
	ESAC
ENDFOR
dst[MAX:512] := 0
