I don't think there is much documentation. In general it should work by implementing the TargetMachine interface (but not LLVMTargetMachine) and using RegisterTargetMachine to get the target into the target registry, possibly also some patches to Triple if you want it to get picked up based on the target triple and not just by -target.

This is from looking around the existing headers, I don't have actually done this myself so I may be missing some things.
