Hi, experts:
I have a question about using compiler's intrinsic function.
It seems EDKII's compiler option doesn't support using intrinsic function.
Such as:
mmintrin.h MMX
xmmintrin.h SSE
emmintrin.h SSE2
pmmintrin.h SSE3
tmmintrin.h SSSE3
intrin.h SSE4A
smmintrin.h SSE4.1
nmmintrin.h SSE4.2
mm3dnow.h 3DNOW
Thanks
Best wishes,
?????

Hi, experts:
I have a question about how to direct compiler to search dedicated include directory.
Such as:
C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include
I tried to tell compiler through “/I” parameter.
“/I C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include”
But failed.

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

Hi, Liming:
Thanks for your reply.
I tried to compile a UEFI shell application.
And this app would call functions provided in mmintrin.h
So, I met this trouble.
Thanks

Technically speaking the compiler generates the code for the intrinsics but the compiler specific include files generally don't just work as they are built to included in the context of that compilers C lib.
I've had some luck using intrinsics from clang, but you have to:
1) Make your own version of the intrinsic header porting it to the edk2 type system, or use portable types.
a) You also need to realized the intrinsics are compiler specific. Generally there is the VC++ and GCC flavors of intrinsics.
b) The intrinsics can also be CPU architecture specific.
2) You can override compiler flags at a driver or library level via the [BuildOptions]section: https://github.com/tianocore/edk2/blob/master/EmulatorPkg/Unix/Host/Host.inf
3) You need to realize the edk2 is not doing the setup for you. So you have to do the CPU ID checks, or turn on the modes required for some things to be valid. Don't cause exceptions as there is no code to handle it. Etc.
Thanks,
