Synopsis
_mm512_mask_i32loscatter_pd(void* base_addr, __mmask8 k, __m512i vindex, __m512d a, int scale);
Description
Stores 8 packed double-precision (64-bit) floating-point elements in "a" to memory locations starting at location "base_addr" at packed 32-bit integer indices stored in "vindex" scaled by "scale". Only those elements whose corresponding mask bit is set in writemask "k" are written to memory.
Operation
FOR j := 0 to 7
i := j*64
m := j*32
IF k[j]
addr := base_addr + SignExtend64(vindex[m+31:m]) * ZeroExtend64(scale) * 8
MEM[addr+63:addr] := a[i+63:i]
FI
