...es constants into register when needed At least first two things will be necessary for my backend too. I start to wonder if it makes sense to make a "BasicInstructionSelector" which will have such reusable logic?

...For now, I recommend just copying the code to get something up and running quickly. In the future we can talk about creating a target independent helper class once we understand the requirements and constraints better. > Sorry if the above is not very clear -- I'm only starting to getting underting > of LLVM codebase.
