Is it possible to convince the compiler to emit code built for the backend
target directly into the same object file as the host code?
I feel like this should be possible, along the lines of
__attribute__((target(...)) to convince the compiler to generate code for a
few functions with different targets than the module?

Using solutions as you suggest above introduces dependent build sequencing
into the build script. Different build systems might prove to be more or
less difficult to integrate cleanly, and many people use build-script
generators which might need to learn a few new tricks.

Any input with your expertise with CUDA will be much appriciated.

But I'll have some established software by that time that I'd love to
attempt to port, we can work through rough edges together when you're
available. No rush.
