Synopsis
_mm512_i32loscatter_epi64(void* base_addr, __m512i vindex, __m512i a, int scale);
Description
Stores 8 packed 64-bit integer elements located in "a" and stores them in memory locations starting at location "base_addr" at packed 32-bit integer indices stored in "vindex" scaled by "scale".
Operation
FOR j := 0 to 7
i := j*64
m := j*32
addr := base_addr + SignExtend64(vindex[m+31:m]) * ZeroExtend64(scale) * 8
MEM[addr+63:addr] := a[i+63:i]
