Yes, thank you, that's it. The only thing is that you don't need the new record `{"llvm.spv.resource.getpointer", 0}` in `ResTypeByArg`. This map contains cases when argument and result types are the same, and in your case it's not true, because argument is Image but result is, for example, i32, if I understood the logic correctly. So without the new record `{"llvm.spv.resource.getpointer", 0}` in `ResTypeByArg` it will be exactly what I had in mind.
