There was a ship-bytecode idea branded HSAIL, associated with opencl finalisers in some way. I'm not sure what killed that - would speculate that the compiler backend was annoyingly slow to run as a JIT. It's somewhat conceptually popular under the spirv branding now. Some of the ROCm libraries are partially written in assembly. Hopefully they all have C reference implementations that can be compiled for the other architectures. My guess is that the AMD strategy of only shipping libraries for some cards + open source means ROCm-ish as built by Linux distros, who are likely to build the libs for all the architectures and not just the special few, can be expected to drive people away from the official releases.
