[X86/ARM] Build on windows

[BredPet]

I tried to compile X86 and ARM on Win. It fails.
X86 logs:

build.cmd x86

I was able to compile X86 with various edits, but there everything doesn't work very well.
Has anyone tried to build these architectures?) Has it ever worked?

[MichalStrehovsky]

There is an issue tracking x86 build that had some work done in the past (see referenced pull requests): #4589.

ARM/ARM64 is probably in a similar state (the runtime and System.Private.* class libraries should be buildable and fully working - it just needs the MSBuild/CMake build work to get it going in the CoreRT build system). We do build these and use these with the closed source .NET Native compiler (the one used to build Universal Windows Apps). The closed source compiler/runtime uses a separate build system that lives on the closed source side, but the files to compile are all here in this repo.

There would be some compiler work needed to emit the assembly helpers to get it working end to end (see things that throw NotImplementedException here (X86)), and we'll need an ObjectWriter package. For ARM, we'll likely want to add support for cross builds in the Windows build system.

We would welcome pull requests in this direction.
