### Self‑Hosting 優先(Phase‑15 基礎固め)
|

- 目的: Nyash製パーサ/言語機能/Bridge整合/パリティを完成させ、自己ホスト c0→c1→c1' を達成する。
|
||||
- 運用:
|
||||
- Runner から `NYASH_USE_NY_COMPILER=1` を推奨(子プロセス実行→JSON v0→Bridge→MIR 実行)。
|
||||
- EXE化は任意の実験導線として維持(配布は Phase‑15 の外)。
|
||||
- PyVM は参照実行器として意味論検証に用い、パリティ監視を継続。
|
||||
|
||||
### Phase 15.2: LLVM(llvmlite)安定化 + PyVM導入
|
||||
- JIT/Cranelift は一時停止(古い/非対応)。Rust/inkwell は参照のみ。
|
||||
- 既定のコンパイル経路は **Python/llvmlite**(harness)のみ

# MIR Builder EXE Design (Phase 15 — EXE‑First)
|
||||
|
||||
Purpose: define a standalone MIR Builder executable that takes Nyash JSON IR (v0/v1) and produces native outputs (object/executable), independent of the Rust Runner/VM. This aligns Phase‑15 with an EXE‑first delivery pipeline.
|
||||
|
||||
Goals
|
||||
- Accept JSON IR from stdin or file and validate semantics (minimal passes).
|
||||
- Emit: object (.o/.obj), LLVM IR (.ll), or final executable by linking with NyRT.
|
||||
- Operate without the Rust VM path; suitable for CLI and scripted pipelines.
|
||||
- Keep the boundary simple and observable (stdout diagnostics, exit codes).
|
||||
|
||||
CLI Interface (proposed)
|
||||
- Basic form
|
||||
- `ny_mir_builder [--in <file>|--stdin] [--emit {obj|exe|ll|json}] -o <out> [options]`
|
||||
- Defaults: `--stdin`, `--emit obj`, `-o target/aot_objects/a.o`
|
||||
- Options
|
||||
- `--in <file>`: Input JSON IR file (v0/v1). If omitted, read stdin.
|
||||
- `--emit {obj|exe|ll|json}`: Output kind. `json` emits validated/normalized IR for roundtrip.
|
||||
- `-o <path>`: Output path (object/exe/IR). Default under `target/aot_objects`.
|
||||
- `--target <triple>`: Target triple override (default: host).
|
||||
- `--nyrt <path>`: NyRT static runtime directory (for `--emit exe`).
|
||||
- `--plugin-config <path>`: `nyash.toml` path resolution for boxes/plugins.
|
||||
- `--quiet`: Minimize logs; only errors to stderr.
|
||||
- `--validate-only`: Parse+validate IR; no codegen.
|
||||
- `--verify-llvm`: Run LLVM verifier on generated IR (when `--emit {obj|exe}`).
|
||||
|
||||
Exit Codes
|
||||
- `0` on success; >0 on error. Validation errors produce human‑readable messages on stderr.
|
||||
|
||||
Input IR
|
||||
- JSON v0 (current Bridge spec). Unknown fields are ignored; `meta.usings` is accepted.
|
||||
- Future JSON v1 (additive) must remain backward compatible; builder performs normalization.
|
||||
|
||||
Outputs
|
||||
- `--emit obj`: Native object file. Uses LLVM harness internally.
|
||||
- `--emit ll`: Dumps LLVM IR for diagnostics.
|
||||
- `--emit exe`: Produces a self‑contained executable by linking the object with NyRT.
|
||||
- `--emit json`: Emits normalized MIR JSON (post‑validation) for roundtrip tests.
|
||||
|
||||
Packaging Forms
|
||||
- CLI executable: `ny_mir_builder` (primary).
|
||||
- Optional shared lib: `libny_mir_builder` exposing a minimal C ABI for embedding.
|
||||
|
||||
C ABI Sketch (optional library form)
|
||||
```c
|
||||
// Input: JSON IR bytes. Output: newly allocated buffer with object bytes.
|
||||
// Caller frees via ny_free_buf.
|
||||
int ny_mir_to_obj(const uint8_t* json, size_t len,
|
||||
const char* target_triple,
|
||||
uint8_t** out_buf, size_t* out_len);
|
||||
|
||||
// Convenience linker: object → exe (returns 0=ok).
|
||||
int ny_obj_to_exe(const uint8_t* obj, size_t len,
|
||||
const char* nyrt_dir, const char* out_path);
|
||||
|
||||
void ny_free_buf(void* p);
|
||||
```
|
||||
|
||||
Internal Architecture
|
||||
- Frontend
|
||||
- JSON IR parser → AST/CFG structures compatible with existing MIR builder expectations.
|
||||
- Validation passes: control‑flow well‑formedness, PHI consistency (incoming edges), type sanity for BoxCall/ExternCall minimal set.
|
||||
- Codegen
|
||||
- LLVM harness path (current primary). Environment fallback via `LLVM_SYS_180/181_PREFIX`.
|
||||
- Option flag `NYASH_LLVM_FEATURE=llvm|llvm-inkwell-legacy` maintained for transitional builds.
|
||||
- Linking (`--emit exe`)
|
||||
- Use `cc` with `-L <nyrt>/target/release -lnyrt` (static preferred) + platform libs `-lpthread -ldl -lm` (Unix) or Win equivalents.
|
||||
- Search `nyash.toml` near the output exe and current CWD (same heuristic as NyRT runtime) to initialize plugins at runtime.
|
||||
|
||||
Integration Points
|
||||
- Parser EXE → MIR Builder EXE
|
||||
- `./nyash_compiler <in.nyash> | ny_mir_builder --stdin --emit obj -o a.o`
|
||||
- Compose with link step for quick end‑to‑end: `... --emit exe -o a.out`
|
||||
- Runner (future option)
|
||||
- `NYASH_USE_NY_COMPILER_EXE=1`: Runner spawns parser EXE; optionally chain into MIR Builder EXE for AOT.
|
||||
- Fallback to in‑proc Bridge when EXE pipeline fails.
|
||||
|
||||
Logging & Observability
|
||||
- Default: single‑line summaries on success, detailed errors on failure.
|
||||
- `--quiet` to suppress non‑essential logs; `--verify-llvm` to force verification.
|
||||
- Print `OK obj:<path>` / `OK exe:<path>` on success (stable for scripts).
|
||||
|
||||
Security & Sandboxing
|
||||
- No arbitrary file writes beyond `-o` and temp dirs.
|
||||
- Deny network; fail fast on malformed JSON.
|
||||
|
||||
Platform Notes
|
||||
- Windows: `.obj` + link with MSVC or lld‑link; prefer bundling `nyrt` artifacts.
|
||||
- macOS/Linux: `.o` + `cc` link; RPATH/loader path considerations documented.
|
||||
|
||||
Incremental Plan
|
||||
1) CLI skeleton: stdin/file → validate → `--emit json/ll` (dry path) + golden tests。
|
||||
2) Hook LLVM harness: `--emit obj` for const/arith/branch/ret subset。
|
||||
3) Linker integration: `--emit exe` with NyRT static lib; add platform matrices。
|
||||
4) Parity suite: run produced EXE against known cases (strings/collections minimal)。
|
||||
5) Packaging: `tools/build_mir_builder_exe.sh` + smoke `tools/mir_builder_exe_smoke.sh`。
|
||||
|
||||
Reference Artifacts
|
||||
- `tools/build_llvm.sh`: current harness flow used as a baseline for emission and link steps。
|
||||
- `crates/nyrt`: runtime interface and plugin host initialization heuristics。

|

- Ny compiler can lex/parse `using` forms without breaking Stage‑1/2 programs
