Re: How to use compiler intrinsic function, such as :mmintrin.h

["Gao, Liming" <liming.gao@intel.com>]

Tiger:
  Yes. EDK2 doesn't support the intrinsic function. Because edk2 compiled EFI image run in target machine instead of OS, they can't link VS system libraries. 

  And, EDK2 doesn't support to specify the include path in BuildOptions. If you want to use EDK2 build system to compile EXE file that run in OS, such as SecMain, you can compile it with system header file and library. The system header file include path is set in ENV include. If you type set include, you will se its value. 

Thanks
