I think finalize_definition may makes sense to be called multiple times in for example a C JIT. After every function definition all pending relocations are likely either resolved outside the current compilation unit, or resolved to a previously defined function. This means that you could immediately perform the relocation of the code without a list of pending relocations consuming unnecessary memory.

In that case, wouldn't the C JIT would have a custom Backend implementation that (hopefully) makes that usage clear in its documentation? I mostly want to be sure that uses of cranelift-module in-tree here are clear about how they should be used.

I'm not sure if trying to write a C JIT on top of cranelift-object would be ideal..

Yeah, a C jit would probably use simplejit. It may want to support aot too though, in which case it would be nice to still support finalize_definitions to be able to make the actual C -> clif part generic over the backend.

Do I need to do anything more to get this merged?
