fix(mir): Receiver used_values for DCE + trace + cleanup
...
- Fix: Call with Callee::Method now includes receiver in used_values()
- Prevents DCE from eliminating Copy instructions that define receivers
- Pattern 3 (loop_if_phi.hako) now works correctly (sum=9)
- Add: NYASH_DCE_TRACE=1 for debugging eliminated instructions
- Shows which pure instructions DCE removes and from which block
- Cleanup: Consolidate Call used_values to single source of truth
- Early return in methods.rs handles all Call variants
- Removed duplicate match arm (now unreachable!())
- ChatGPT's suggestion for cleaner architecture
- Docs: Phase 166 analysis of inst_meta layer architecture
- Identified CSE pass callee bug (to be fixed next)
- Improvement proposals for CallLikeInst

refactor(funcscanner): Region+next_i パターン統一 & SSA テスト追加
...
**FuncScanner .hako 側改善**:
- scan_all_boxes を Region + next_i 形式に統一(continue 多発による SSA/PHI 複雑さ削減)
- インデント修正(タブ→スペース統一)
- デバッグ print 削除
**SSA テスト追加**:
- lang/src/compiler/tests/funcscanner_scan_methods_min.hako
- src/tests/mir_funcscanner_ssa.rs (scan_methods & fib_min SSA デバッグテスト)
**Phase 25.3 ドキュメント**:
- docs/development/roadmap/phases/phase-25.3-funcscanner/ 追加
**関連**: Phase 25.3 FuncScanner 箱化準備作業

feat(loop-phi): Add body-local variable PHI generation for Rust AST loops
...
Phase 25.1c/k: Fix ValueId undefined errors in loops with body-local variables
**Problem:**
- FuncScannerBox.scan_all_boxes/1 and BreakFinderBox._find_loops/2 had ValueId
undefined errors for variables declared inside loop bodies
- LoopFormBuilder only generated PHIs for preheader variables, missing body-locals
- Example: `local ch = s.substring(i, i+1)` inside loop → undefined on next iteration
**Solution:**
1. **Rust AST path** (src/mir/loop_builder.rs):
- Detect body-local variables by comparing body_end_vars vs current_vars
- Generate empty PHI nodes at loop header for body-local variables
- Seal PHIs with latch + continue snapshot inputs after seal_phis()
- Added HAKO_LOOP_PHI_TRACE=1 logging for debugging
2. **JSON v0 path** (already fixed in previous session):
- src/runner/json_v0_bridge/lowering/loop_.rs handles body-locals
- Uses same strategy but for JSON v0 bridge lowering
**Results:**
- ✅ FuncScannerBox.scan_all_boxes: 41 body-local PHIs generated
- ✅ Main.main (demo harness): 23 body-local PHIs generated
- ⚠️ Still some ValueId undefined errors remaining (exit PHI issue)
**Files changed:**
- src/mir/loop_builder.rs: body-local PHI generation logic
- lang/src/compiler/entry/func_scanner.hako: debug logging
- /tmp/stageb_funcscan_demo.hako: test harness

refactor: MIR instruction.rs 4-Phase大型リファクタリング完了(888→315行、64%削減)
...
Single Responsibility Principle適用による完全分離:
- Phase 1: テスト分離 → instruction/tests.rs (196行)
- Phase 2: Display実装分離 → instruction/display.rs (130行)
- Phase 3: メソッド実装分離 → instruction/methods.rs (247行)
- Phase 4: 統合テスト成功(全コンパイルエラー解決)
技術的成果:
- MirInstruction enumを単一責任に集中
- 各実装が独立して保守可能な構造
- EffectMask::read→READ修正も完了
- ビルド成功確認済み(警告のみ)
