What do you mean by polyglot? As in multiple hardware, or mixed-source? HIP is mostly API-compatible with CUDA, so you can just mix host code and device code with it. That said, ROCm does indeed work with machine code instead of IR. You can compile fat binaries with more than one type of machine code and they'll work on any of the chips you compiled for, at the cost of the binaries becoming, well, basically obese if you want a decent range of hardware supported.
