What is the latest status of llc support on WIndows platform?

I want to know whether llc can emit .s on windows or is there any project going on to support it?

And what is the effort needed to support it on windows?

Thanks,

iirc llc can emit .s files on windows since LLVM 1.7 (or maybe even before)
http://llvm.org/docs/GettingStarted.html#requirements is a good thing to read

And what is the effort needed to support it on windows?

Compile it and use it.
