Thank you Liming. That is cool feature.
Thank you

> Subject: [edk2-devel] [Patch 00/12] New Cross OS tool chain CLANG9
>
> BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1603
> Code: https://github.com/lgao4/edk2/tree/CLANG9
> Wiki: https://github.com/lgao4/edk2/wiki/CLANG9-Tools-Chain
>
> CLANG9 tool chain is added to directly generate PE/COFF image (EFI image).
> This tool chain uses LLVM clang C compiler and lld linker, generates PE/COFF
> image and PDB compatible debug symbol format. Now, it supports IA32/X64
> Archs.
> It must use LLVM 9 or above release. LLVM 9 is ready on
> http://releases.llvm.org/download.html#9.0.0.
>
> CLANG9 is the cross OS tool chain. It can work on Windows/Linux/Mac host OS.
> For the same source code, with the same version LLVM tool chain,
> CLANG9 can generate the same binary image. So, the developer can
> choose the different development environment and work on the same
> code base. Besides, EDKII project build also requires third party
> tools: nasm and iasl. They both keep the same version. If so, the same
> binary image can be generated on the different host OS.
>
> LLVM tool chain provides the compiler and linker. To build EDK2 project,
> some other tools are still required. On Windows OS, nmake and Visual Studio
> are required to call Makefile and compile BaseTools C tools.
> On Linux/Mac, binutils and gcc are required to make and compile BaseTools
> C tools. Because VS or GCC are mainly used to compile BaseTools and provide
> nmake/make tool, they can keep on the stable version without update.
>
> To build source code, CLANG9 tool chain (-t CLANG9) can be specified
> on Windows OS, set CLANG_HOST_BIN=n, set CLANG9_BIN=LLVM installed
> directory
> CLANG_HOST_BIN is used CLANG_HOST_PREFIX. Prefix n is for nmake.
> For example:
> * set CLANG_HOST_BIN=n
> * set CLANG9_BIN=C:\Program Files\LLVM\bin\
> * set IASL_PREFIX=C:\Asl\
>
> On Linux/Mac, export CLANG9_BIN=LLVM installed directory,
> CLANG_HOST_BIN is
> not required, because there is no prefix for make.
> For example:
> * export CLANG9_BIN=/home/clang9/bin/
>
> Now, CLANG9 tool chain has been verified in Edk2 packages and Ovmf/Emulator
> with LLVM 9.0.0 on Windows and Linux OS.
> OVMF IA32/X64/IA32X64 all boots to Shell on Windows and Linux OS.
> Emulator can boot to Shell on Windows only with CLANG9.
> OVMF Ia32X64 RELEASE build generates the same BIOS images on Windows and
> Linux OS.
