From 78c9d4d7fcff33242ceafa433f3785dd757ced6c Mon Sep 17 00:00:00 2001 From: nyash-codex Date: Sun, 23 Nov 2025 14:47:00 +0900 Subject: [PATCH] =?UTF-8?q?feat(joinir):=20Phase=2027.8-1~3=20=E2=80=94=20?= =?UTF-8?q?Ops=20Box=E5=B0=8E=E5=85=A5=20+=20Toggle=E5=AF=BE=E5=BF=9C?= =?UTF-8?q?=E5=AE=8C=E4=BA=86?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Phase 27.8-1: JoinIR 命令意味箱（Ops Box）作成 ✅ **新規ファイル**: `src/mir/join_ir_ops.rs` - `eval_binop()`: Add, Sub, Mul, Div, Or, And の評価ロジック一元化 - `eval_compare()`: Lt, Le, Gt, Ge, Eq, Ne の比較ロジック一元化 - エラー処理: `JoinIrOpError` 型で型安全 - 完全テストカバレッジ: 13個のユニットテスト **効果**: - BinOp/Compare の評価ロジックを一箇所に集約 - 再利用可能な API で将来の拡張が容易 - テスタビリティ向上 ## Phase 27.8-2: join_ir_runner.rs の Ops Box 統合 ✅ **変更**: `src/mir/join_ir_runner.rs` - BinOp/Compare の実装を ops box に完全移譲（約70行削減） - `JoinValue` / `JoinIrOpError` を ops box から再エクスポート - 後方互換性維持: `JoinRuntimeError = JoinIrOpError` **効果**: - コード重複削減（約70行） - 実装の一貫性保証（ops box の単一実装を使用） ## Phase 27.8-3: MIR→JoinIR Toggle 対応 ✅ **変更**: `src/mir/join_ir.rs` - `lower_skip_ws_to_joinir()`: トグル対応ディスパッチャー - `lower_skip_ws_handwritten()`: 既存実装をリネーム（Phase 27.1-27.7） - `lower_skip_ws_from_mir()`: MIR自動解析版スタブ（Phase 27.8-4 で実装予定） **環境変数制御**: ```bash # 手書き版（デフォルト） ./target/release/hakorune program.hako # MIR自動解析版（Phase 27.8-4 実装予定） NYASH_JOINIR_LOWER_FROM_MIR=1 ./target/release/hakorune program.hako ``` **効果**: - 段階的な移行が可能（既存動作を完全に維持） - A/B テストによる検証が容易 ## 変更ファイル - `src/mir/join_ir_ops.rs` (新規): Ops Box 実装 - `src/mir/join_ir_runner.rs`: Ops Box 使用に変更 - `src/mir/join_ir.rs`: Toggle 対応ディスパッチャー追加 - `src/mir/mod.rs`: join_ir_ops モジュール追加 ## コンパイル結果 ✅ 0 errors, 18 warnings（既存警告のみ） ✅ ビルド成功 ## 次のステップ **Phase 27.8-4**: `lower_skip_ws_from_mir()` 本実装 - MirQuery を使った MIR 解析 - パターンマッチング（init, header, break checks, body） - JoinIR 自動生成（entry function + loop_step function） 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/mir/join_ir.rs | 56 +++++++- src/mir/join_ir_ops.rs | 273 ++++++++++++++++++++++++++++++++++++++ src/mir/join_ir_runner.rs | 110 ++------------- src/mir/mod.rs | 1 + 4 files changed, 343 insertions(+), 97 deletions(-) create mode 100644 src/mir/join_ir_ops.rs diff --git a/src/mir/join_ir.rs b/src/mir/join_ir.rs index 6d04f1e1..29d8b964 100644 --- a/src/mir/join_ir.rs +++ b/src/mir/join_ir.rs @@ -437,7 +437,11 @@ pub fn lower_min_loop_to_joinir(module: &crate::mir::MirModule) -> Option Option { +/// Phase 27.8: Main.skip/1 の JoinIR lowering（手書き版） +/// +/// Phase 27.1-27.7 で実装された hand-written JoinIR 生成。 +/// Phase 27.8 以降は `lower_skip_ws_from_mir()` に移行予定。 +fn lower_skip_ws_handwritten(module: &crate::mir::MirModule) -> Option { // Step 1: "Main.skip/1" を探す let target_func = module.functions.get("Main.skip/1")?; @@ -606,6 +610,56 @@ pub fn lower_skip_ws_to_joinir(module: &crate::mir::MirModule) -> Option Option { + // Step 1: "Main.skip/1" を探す + let target_func = module.functions.get("Main.skip/1")?; + + eprintln!("[joinir/skip_ws/mir] Found Main.skip/1 (MIR-based lowering)"); + eprintln!("[joinir/skip_ws/mir] MIR blocks: {}", target_func.blocks.len()); + + // Phase 27.8: TODO - MirQuery を使った MIR 解析実装 + // 現在は手書き版にフォールバック + eprintln!("[joinir/skip_ws/mir] WARNING: MIR-based lowering not yet implemented, falling back to handwritten"); + lower_skip_ws_handwritten(module) +} + +/// Phase 27.8: Main.skip/1 の JoinIR lowering（トグル対応ディスパッチャー） +/// +/// 環境変数 `NYASH_JOINIR_LOWER_FROM_MIR=1` に応じて、 +/// hand-written 版または MIR 自動解析版を選択する。 +/// +/// ## トグル制御: +/// - **OFF (デフォルト)**: `lower_skip_ws_handwritten()` を使用 +/// - **ON**: `lower_skip_ws_from_mir()` を使用 +/// +/// ## 使用例: +/// ```bash +/// # 手書き版（既定） +/// ./target/release/hakorune program.hako +/// +/// # MIR 自動解析版 +/// NYASH_JOINIR_LOWER_FROM_MIR=1 ./target/release/hakorune program.hako +/// ``` +pub fn lower_skip_ws_to_joinir(module: &crate::mir::MirModule) -> Option { + if env_flag_is_1("NYASH_JOINIR_LOWER_FROM_MIR") { + eprintln!("[joinir/skip_ws] Using MIR-based lowering (NYASH_JOINIR_LOWER_FROM_MIR=1)"); + lower_skip_ws_from_mir(module) + } else { + eprintln!("[joinir/skip_ws] Using handwritten lowering (default)"); + lower_skip_ws_handwritten(module) + } +} + /// Phase 27.1: FuncScannerBox.trim/1 の MIR → JoinIR 変換 /// /// 目的: lang/src/compiler/entry/func_scanner.hako の trim メソッドを JoinIR に変換 diff --git a/src/mir/join_ir_ops.rs b/src/mir/join_ir_ops.rs new file mode 100644 index 00000000..6f052d9b --- /dev/null +++ b/src/mir/join_ir_ops.rs @@ -0,0 +1,273 @@ +//!
