about

nx_compile_x86.nx -- source-file driver for the NishiLang x86_64 backend. Reads .nx source on stdin (pre-expanded; imports already inlined), runs: lex_source -> parse_module -> opt_run (per function) -> x86ctx_emit_module and writes the AT&T x86_64 asm to stdout. The bash wrapper (bench/nx_compile_x86.sh) drives the source -> native ELF pipeline: nxc2.exe --target asm runtime/nx_compile_x86.nx (build driver) riscv64-as + ld -> nx_compile_x86.elf cat source.nx | qemu-riscv64-static nx_compile_x86.elf -> x86_64 asm on stdout gcc -nostdlib -static asm -o native.elf run natively Per cardinal feedback-no-nxc2-c-extension-only-nishilang-forward: this driver is the NishiLang counterpart of nxc2.exe's --target x86_64 path. No C-side modifications. nx_safety_envelope: intended_use: "Compile a .nx source (pre-import-expanded) to native x86_64 SysV asm via the IR-driven x86_64 backend." sil_target: SIL3 asil_target: QM dal_target: DAL B iec_62304_class: NONE evidence: [no_floating_point, bounded_stdin_read_per_jpl_rule_2, sealed_pipeline_verdict_codes, opt_optional_via_env] hazard_register: [bug-tape-source-exceeds-cap-silently-truncated, bug-tape-opcode-not-yet-wired-passes-through] residual_risk: "Hard 2 MiB source cap; pasting larger files truncates silently.
