As far as I know SPIR is a LLVM IR subset based on LLVM 3.0. 
Currently, I don't know what needs to be done here.

But in general it should be possible. Here is a tutorial which 
shows how to compile Ada to a CUDA kernel:

This can be done with D, too. It requires some fiddeling with 
address spaces which is currently not implemented.
