the dwo files should be able to be assembly without any particular restrictions/complications in authoring them, right? (taking the assembly of a split DWARF compilation and pulling out the .dwo parts should be adequate, I think)
The executable - it could probably actually be an object file that happens to have two skeleton units in it (like we generate under LTO, for instance - though without any of the LTO-specific cross-CU references) so that could be written in assembly relatively easily (to hand-craft it you could probably take the assembly of the two skeletons and copy/paste them into one file for instance)
