about

nx_rv64_jit_gate.nx -- GATE: the sovereign RV64->x86-64 JIT is (a) CORRECT (a JIT'd count-loop gives the same result as the predecoded interpreter -- equivalence vs the golden execution model) and (b) DRAMATICALLY FASTER (a native x86 loop vs an interpreted one). Proves the SOTA emulator technique (dynamic binary translation) works end-to-end sovereignly: RV64 -> native x86-64 -> mmap RWX -> CALL. expect_exit:0
