>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.
