about

nx_emu_bench.nx -- MEASURE the sovereign rv64 emulator's throughput (instructions/sec) so the "behind QEMU on perf" claim is a NUMBER, not a hand-wave (measured-not-asserted). Assembles a compute loop with the sovereign assembler (nx_rv64_asm), runs it IN-PROCESS on rv64im_min_sim with a high step cap, times the run with sys_now_us, and reports the measured instr/sec + a bounded honest comparison to QEMU-TCG's ballpark. expect_exit:0
