How to build EDK2 project for ARM using LLVM tool chain

[Prem Kumar]

Hi All,
 Kindly provide your comments to build EDK2 project for ARM AARCH64/ARM
using LLVM tools chain under Windows environment.

I've below tools,
 - Visual Studio 2015
 - LLVM 4.0


Any pointer is helpful to proceed further.


Note:
 I'm able to build EDK2 project(Nt32Pkg) using Visual studio under Windows
environment.

Thanks,
Prem.

Visual Studio 2015 does not support AARCH64 (and possibly not ARM).
You need at least VS 2017 version 15.4. (This does not mean that all
versions of VS 2018 will work.)

Since this has not been a common way of building for ARM/AARCH64 in
the past, there are some aspects of the tree that may not build
cleanly (and some .asm files that are missing for AARCH64).

For LLVM on the whole, I would recommend building under WSL (Windows
Subsystem for Linux) rather than going down a more Windows-specific
route (of which I'm only aware of cygwin).

For building under WSL, you can follow the instructions at
