Phase v2-B loopform.hako 完全実装: 【実装】 - loopform.hako (258行): 6-block LoopForm 完全実装 - Header PHI: incoming 配列 + computed フラグ - Dispatch PHI (tag/payload): break/continue 処理 - Condition: MIR/Payload/Guard 全モード対応 - Safepoint: GC 安全点統合 - builder.hako (392行): 9 LLVM instructions 統合 - instructions/*.hako (9ファイル): 全命令実装 【テスト】 - Unit test: test_basic.hako (4 tests, 159行) - Smoke tests (3本, 130行): - while_simple.hako: 基本 while ループ - for_counter.hako: payload mode カウンタ - if_loop_merge.hako: 複合制御フロー + guard 【進捗】 - Stage 1: スケルトン実装 ✅ - Stage 2: PHI incoming 配列化 ✅ - Stage 3: Safepoint & Condition ✅ (Stage 1に含む) - Stage 4: スモークテスト3本 ✅ 【成果】 - 実装: 258行 (Python 224行 + 機能拡張) - テスト: 289行 (unit 159行 + smoke 130行) - ビルド: 成功 (0 errors) 次: Phase v2-C MIR Call 統合 + C++ backend 実装 Ref: docs/private/roadmap/phases/phase-33/PHASE_V2_LOOPFORM_*.md
