Hi Yuanming Hu. Please add support for old processors. CPU info: Model 45. Intel xeon e5-2670 Thanks.

I have tried compiling on Ubuntu 17.10, Intel I7-8550u (kabylake).

Clang9 , GCC8/9 does not like the cpu intrinsics used in particular (BMI2). I am not sure if this is a specific issue with my system environment / mobile CPU, but the #HASWELL struggles to work. Unfortunately had to turn this off.
