This component compiles C, C++, Objective C, and Objective C++ code into LLVM bitcode. Clang typically uses LLVM libraries to optimize the bitcode and emit machine code. LLVM fully supports the COFF object file format, which is compatible with all other existing Windows toolchains.

What is considered best practice to get LLVM working on Windows?
The Zig project hosts prebuilt LLVM binaries for windows: https://github.com/ziglang/zig/wiki/Building-Zig-on-Windows Their prebuilt binaries seem to have much more included than the official LLVM windows package. It's insane that this is the easiest way to get LLVM on windows, but it's the best I've come across. EDIT: Looks like there are also build instructions there, that could be helpful too More on reddit.com

November 3, 2021Does LLVM work on Windows?

GNU Binutils 2.19.1 Gold: This version of Gold contained a bug which causes intermittent failures when building LLVM with position independent code. The symptom is an error about cyclic dependencies. We recommend upgrading to a newer version of Gold. This section mostly applies to Linux and older BSDs. On macOS, you should have a sufficiently modern Xcode, or you will likely need to upgrade until you do. Windows does not have a “system compiler”, so you must install either Visual Studio 2019 (or later), or a recent version of mingw64.

r/Compilers on Reddit: What is considered best practice to get LLVM working on Windows?
November 3, 2021 -
Do I really have to build the whole thing just to be able to use it for codegen on Windows?
I know I can use msys2 (and it works actually), but AFAIK, because it simulates more or less Linux, it is not possible to build for Visual Studio 2019 and thus also use the Visual Studio debugger (correct me if I'm wrong of course, hopefully I am).
Before I invest even more time than I already did into simply making llvm work on Windows, I'd like to know what is the best practice to use llvm for codegen on Windows?

In my experience, vcpkg + cmake inside a visual studio command prompt is the least-painful way to get a useful llvm dependency on Windows. See the "Building Halide with Cmake", subsection "Windows" in the Halide readme for an example of how such a build can be set up: https://github.com/halide/Halide/blob/master/README.md
