Added something, though I don't know if it helps. There aren't any "tricky" situations here, basically, the only requirement is to have a function in multiple sections. Its just that creating a binary with deterministic content takes up a bunch of space (for the DWARF mainly). It would be possible to create this setup with a compiler, but then both the instructions and their addresses would be unpredictable so it would be hard to assert anything.
