That would be number 2.
The LLVM backend is fundamentally different from Walters, and I'm not using
them at all.

My compiler is based on the toElem and toObjFile backend functions only.
Eventually I'll be moving away from those too and roll my own completely...
But that is for the future...

I anticipate having a pre-alpha release ready in a week or two, then you can
take a look yourself.

Also you might be interested in Gregor Richards DMDFE *[1] which is the DMD
frontend with all the backend stuff removed, and it compiles
out-of-the-box.
