x86.ml is an instruction selector for the part of Tast that fits in one integer register: literals, slots, let, if, arithmetic, comparison, and a call. Everything else raises with the node that defeated it, because an honest refusal is the measurement and a silently wrong answer would waste the exercise. The frontend is the real one -- Reader, Parse, Load, Check -- so what is lowered is the same Tast.fn the LLVM backend gets. Seven arithmetic results are compared against what the language says they should be; the disassembly proves nothing and is not the evidence. Nothing is wired into the build. No dune file under spike/, driven by hand with ocamlfind and clang as spike/embed already does.
