太厉害了……
你是说用 128 位寄存器以 SIMD 方式一次处理四个 32 位数据？我想了很久，但觉得由于加法进位会串到相邻的值，这应该不可能实现。
英文原文
That's amazing...
So are you saying you use 128-bit registers to SIMD four 32-bit data at once? I've wondered about that for a long time, but I didn't think it would be possible due to addition carrying into the neighbour's value.
