Modularizing LLVM codegen/JIT

A question I have for @kparzysz : I think we have spent some time in this thread trying to understand the intended way to use LLVM. I’d argue that while it’s good to understand LLVM’s design intent, the beaten path is that which is well-tested in LLVM (particularly if we intend to be compatible with a wide range of LLVM versions). Therefore, I’m curious whether you know if LLVM is exercised in test against multiple backends in the same process?

No, that has never been tested. That has not been a design goal of LLVM in the past, although, given the interest in heterogeneous targets, it may become one in the future. This is not to say that it won’t work, just that there hasn’t been any specific effort to make it work. It someone wanted to work on it, I bet it would be welcome in the LLVM community.
