feat: Add VM instruction statistics and fix plugin TLV debugging
Major changes: - Add --vm-stats and --vm-stats-json CLI flags for VM instruction profiling - Implement instruction counting by opcode type with JSON output support - Add enhanced TLV debug logging with NYASH_DEBUG_PLUGIN=1 environment variable - Fix missing fields in CliConfig and ASTNode::BoxDeclaration for test compatibility - Improve plugin method call error messages with argument count/type details This enables MIR→VM conversion health checks and supports the Phase 8.6 VM optimization goals. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

# 🎯 CURRENT TASK - 2025年8月20日
|
||||
# 🎯 CURRENT TASK - 2025年8月23日(刷新)
|
||||
|
||||
## 📊 現在の状況
|
||||
## ✅ 直近の完了
|
||||
1. ドキュメント再編成の完了(構造刷新)
|
||||
2. プラグインBox(FileBox)基本実装とインタープリター統合
|
||||
3. VM命令カウンタ+時間計測のCLI化(`--vm-stats`, `--vm-stats-json`)とJSON出力対応
|
||||
|
||||
### ✅ 完了したタスク
|
||||
1. **ドキュメント再編成** - 完全完了!
|
||||
- 283ファイル → 4大カテゴリに整理
|
||||
- Phaseファイルも統合済み
|
||||
- 説明書/予定フォルダ削除済み
|
||||
## 🚧 次にやること(再開方針)
|
||||
|
||||
2. **プラグインBox基本実装** (Phase 9.78c)
|
||||
- FileBoxプラグイン実装済み
|
||||
- インタープリター経由の呼び出し成功
|
||||
- 基本的な引数/戻り値サポート追加(ChatGPT5による)
|
||||
1) MIR→VMの健全化(短期・最優先)
|
||||
- 現行MIR→VMのマッピング表を作成(欠落/冗長/重複を可視化)
|
||||
- サンプル/テストをVMで実行し、差分ログ(例外系・returns_result)を確認
|
||||
- 成果物: `docs/reference/architecture/mir-to-vm-mapping.md`(暫定)
|
||||
|
||||
### 🚧 現在の課題
|
||||
1. **Bashコマンドエラー問題**
|
||||
- docs整理で現在のディレクトリが削除された影響
|
||||
- セッション再起動が必要かも
|
||||
2) VM×プラグインシステムのE2E検証(短期)
|
||||
- `tests/e2e_plugin_filebox.rs` をVMでも通す(`--features plugins`)
|
||||
- ケース: `new/close`, `open/read/write`, `copyFrom(handle)`、デリゲーション from Parent
|
||||
- 成果物: テストグリーン+既知の制約を `VM_README.md` に明記
|
||||
|
||||
2. **E2Eテスト状況**(tests/e2e_plugin_filebox.rs)
|
||||
- インタープリターテスト: ✅ 成功(FileBox.close()が"ok"を返す)
|
||||
- デリゲーションテスト: ❓ 未実装の可能性
|
||||
- VMテスト: ❌ 失敗(VMはまだプラグインBox未対応)
|
||||
3) 命令セットのダイエット(中期:目標26命令)
|
||||
- 実行統計(`--vm-stats --vm-stats-json`)でホット命令を特定
|
||||
- 統合方針(例: TypeCheck/Castの整理、Array/Ref周りの集約、ExternCall→BoxCall移行)
|
||||
- 段階移行(互換エイリアス→削除)と回帰テスト整備
|
||||
- 成果物: 26命令案ドラフト+移行計画
|
||||
|
||||
### 🎯 次のタスク(MIR→VM チェック / 命令最適化)
|
||||
## ▶ 実行コマンド例
|
||||
|
||||
1) MIR→VM 変換の健全性チェック(短期)
|
||||
- 現行 MIR 命令 → VM 命令のマッピング表を作成
|
||||
- E2E/サンプルを VM バックエンドで実行し、MIR→VM 変換ログを収集
|
||||
- 例外系・Result正規化(returns_result)の経路を VM で確認
|
||||
計測実行:
|
||||
```bash
|
||||
nyash --backend vm --vm-stats --vm-stats-json local_tests/test_hello.nyash > vm_stats.json
|
||||
```
|
||||
|
||||
2) 命令使用実績の計測(短期)
|
||||
- 実際に使用されている VM 命令を計測(実行ログ/カウンタ)
|
||||
- 現行宣言33命令 → 実使用コア命令の抽出
|
||||
VM×プラグインE2E:
|
||||
```bash
|
||||
cargo test -q --features plugins e2e_interpreter_plugin_filebox_close_void
|
||||
cargo test -q --features plugins e2e_vm_plugin_filebox_close_void
|
||||
```
|
||||
|
||||
3) 命令セットのダイエット検討(中期)
|
||||
- 目標: 26命令(docsの合意値)
|
||||
- 代替可能/統合可能な命令の提案と互換性影響の洗い出し
|
||||
- 実験フラグで26命令版のVMを試作(段階移行)
|
||||
MIRダンプ/検証:
|
||||
```bash
|
||||
nyash --dump-mir --mir-verbose examples/plugin_box_sample.nyash
|
||||
nyash --verify examples/plugin_box_sample.nyash
|
||||
```
|
||||
|
||||
4) ドキュメント更新(短期)
|
||||
- 現状の命令一覧と目標26命令の整合(reference/architecture/)
|
||||
- 計測結果(使用頻度)と統合方針を追記
|
||||
## 🔭 26命令ターゲット(ドラフトの方向性)
|
||||
コア(候補): Const / Copy / Load / Store / BinOp / UnaryOp / Compare / Jump / Branch / Phi / Call / BoxCall / NewBox / ArrayGet / ArraySet / RefNew / RefGet / RefSet / WeakNew / WeakLoad / BarrierRead / BarrierWrite / Return / Print or ExternCall(→BoxCall集約) + 2枠(例外/await系のどちらか)
|
||||
|
||||
### 📝 メモ
|
||||
- ChatGPT5がプラグインBoxメソッド呼び出しに引数/戻り値サポートを追加
|
||||
- TLV (Type-Length-Value) エンコーディングで引数をプラグインに渡す実装
|
||||
- Rustの借用チェッカーとの格闘の跡が見られる(複数回の修正)
|
||||
|
||||
### 🔧 推奨アクション
|
||||
1. VMバックエンドでの実行ログ化(命令発行ログ/カウンタ)
|
||||
2. マッピング表作成(MIR→VM)と欠落/冗長命令の洗い出し
|
||||
3. 26命令案のPoCブランチ作成→E2Eで回帰確認
|
||||
4. docs更新(命令一覧、設計意図、移行戦略)
|
||||
補助: Debug/Nop/Safepointはビルドモードで有効化(命令としては非中核に降格)
