Proposal made by Tobias is very elegant, but it seems to be addressing the case when host and sub-architectures' code exist in the same time.

I don't know why that would have to be the case. Couldn't your accelerator backend simply read in the proposed IR string and optimize/codegen it?

May I kindly point out that to our experience the really efficient deeply specialized sub-architectures code may simply not exist at compile time, while the generic baseline host code always can.

As I mentioned earlier, I am more concerned about the case where there is no accelerator compiler executed at runtime. All the code for the host and accelerate needs to be available in native format at run time. A string representation in the object file doesn't allow that.
