当从GetSpr寄存器（AR）获取的值为零或负数时，计算唯一ID数量的逻辑可能导致uniqueIdNum变量下溢，产生溢出数据，导致后续计算循环取出非法值，导致aic error
Ascend950
构造indices 值全为-1 时，例如[-1,-1,-1]
indices 值越界或者负索引都能正常执行，不能aic error
errcode:(263, 95) errorStr: CCU instruction address check error.The DDR address of the MTE instruction is out of range. subErrType: 0x4.
