about
nx_nxc_baremetal.nx -- THE FULL PRODUCT LOOP: NishiLang SOURCE -> self-hosted nxc -> RV64 ELF -> QEMU-validated
emulator. Reads a NishiLang program compiled to a RISC-V Linux ELF by the SOVEREIGN self-hosted nxc (source -> lex ->
parse -> IR -> opt -> regalloc -> riscv -> ELF), extracts its .text, and bridges the Linux-ELF -> bare-metal gap:
prepend an sp shim (Linux gives argc/argv on the stack; bare-metal doesn't), patch the codegen's `li a7,93; ecall`
exit to a `jal` to a UART-emit(a0) + SiFive-finisher epilogue (assembled by the sovereign nx_rv64_asm). Runs the
result on the QEMU-validated golden sim (rv64im_min_sim) + writes a flat bin for qemu-system-riscv64 (the liar-killer).
sum10.nx returns 55 = 0x37. So the WHOLE sovereign source->RISC-V toolchain is validated against QEMU. expect_exit: 0
