No, I mean a set of methods that can be called to create the backend's IR
and compile it and get function pointers to the final executable code. This
is what the layer that translates from SPIR-V to LLVM IR actually calls to
create the LLVM IR.

btw i spoke to robin kruppe, he has an implementation of the

Sounds good. If nothing's happened in a while, you may want to ping the RVV
workgroup as someone may have forgotten. I personally would publish it in a
personal repo and when the RVV WG get around to it, it could be moved.
