Supporting `-fno-gpu-rdc` should be easy, this will just require a few tweaks to the driver phases and passing it to the host backend directly. Supporting Windows would be a little tougher, we would need to make sure we can embed / extract the device code with Windows. After that we would need to synthesize the start / stop pointers differently. There is a way to do this on Windows similar to how Unix linkers, there's some examples in ASAN or HWSAN I believe. It's definitely doable but would take some effort, so it definitely won't work in time for the 15 release. I personally don't have much interest in Mac or Windows, but if I want to make this format universal I may need to actually sit down and implement it.
