about

nx_nxc_run.nx -- GENERIC runner: reads a NishiLang program compiled to RV64 ELF by the self-hosted nxc (knowledge/hw/nxc_in.elf), bridges Linux-ELF -> bare-metal (sp shim + patch `li a7,93; ecall` -> jal to a UART-emit(a0) + SiFive-finisher epilogue via sovereign nx_rv64_asm), runs it on the QEMU-validated golden sim (prints NXCSIM: <hex>), and writes the bare-metal image to knowledge/hw/nxc_bare.bin for the qemu-system-riscv64 liar-killer. Drives the diverse-program validation of the sovereign NishiLang source->RISC-V toolchain. expect_exit: 0
