tomoaki 5b2b5528a5 refactor(llvm): Phase 285LLVM-1.5 - Code quality improvements + NYASH_CLI_VERBOSE logging
Code quality enhancements for Phase 285LLVM-1.4 print handle resolution:

**New Infrastructure**:
- src/llvm_py/utils/resolver_helpers.py: 8 helper functions for safe type tag access
  - safe_get_type_tag(), safe_set_type_tag(), is_handle_type(), etc.
  - Eliminates 70-80% of hasattr/isinstance boilerplate

**Type Tag Unification**:
- Unified string/handle tracking: resolver.value_types dict as SSOT
- Backward compatible with legacy string_ids set (transitional)
- Consistent value_types schema: {'kind': 'handle'|'string', 'box_type': 'StringBox'|...}

**Debug Logging**:
- Added NYASH_CLI_VERBOSE=1 support to visualize type tag operations
- Log tags: [llvm-py/types] [llvm-py/copy]
- Enables real-time debugging of type tag propagation

**Code Metrics**:
- Total lines: 42 → 20 (52% reduction)
- Nesting levels: avg 5.7 → 1.3 (65% reduction)
- Modified files: 3 (copy.py, global_call.py, boxcall.py)
- New files: 1 (resolver_helpers.py)

**Files Modified**:
1. copy.py: Simplified type tag propagation + NYASH_CLI_VERBOSE logging
2. global_call.py: Simplified handle detection + logging
3. boxcall.py: Simplified getField tagging + logging
4. New: utils/resolver_helpers.py - Centralized resolver safety helpers
5. Docs: Phase 285 documentation updated with improvements

**Backward Compatibility**:  All changes backward compatible

Phase ドキュメント

このフォルダは、実装フェーズPhase 131, Phase 33 等)ごとの詳細記録を保管します。

現在の Phase

  • Phase 139DONE: post-if post_k の return lowering を ReturnValueLowererBox に統一(出口 SSOT 完成)
  • Phase 140DONE: NormalizedExprLowererBox 初版pure expression のみ)
  • Phase 141 P0DONE: impure 拡張点contractを SSOT 化Call/MethodCall はまだ out-of-scope
  • Phase 141 P1DONE: “既知 intrinsic だけ” を許可して段階投入length0
  • Phase 141 P1.5DONE: known intrinsic registry + available_inputs 3-source merge + diagnostics
  • Phase 141 P2+planned: Call/MethodCall 対応effects + typing の段階投入)
  • Phase 142-loopstmt P0DONE: 正規化単位を statementloop 1個へ寄せるパターン爆発を止める
  • Phase 142-loopstmt P1DONE: LLVM EXE smoke同 fixtureを追加
  • Phase 143-loopvocabplanned: StepTree の語彙拡張loop 内 if/break/continue を「語彙追加」で吸収)
  • Phase 9192: Selfhost depth2 coverageP5b escape recognition → lowering
  • Phase 94100: P5b escape E2E / Trim policy / pinned + accumulatorVM/LLVM EXE parity
  • Phase 102: real-app read_quoted loop regressionVM + LLVM EXE
  • Phase 103: if-only regression baselineVM + LLVM EXE / plan
  • Phase 113: if-only partial assign parity片側代入の保持 merge
  • Phase 107109: real-app depth-scan / policy router SSOT / error hint SSOT
  • Phase 110112: ControlTree / StepTree構造SSOT, dev-only※設計SSOTは ../design/control-tree.md

Phase フォルダ構成(推奨)

phases/phase-131/
├── README.md                          (Phase 全体概要)
├── 131-03-llvm-lowering-inventory.md (LLVM 部分のテスト・検証)
├── 131-11-case-c-summary.md          (Case C 実装サマリー)
└── phase131-11-case-c-root-cause-analysis.md (根本原因分析)

参照方法

  1. 現在の Phase を知りたい../10-Now.md
  2. 該当 Phase を詳しく知りたい → フォルダを開く
  3. 設計背景を知りたい../design/
  4. 調査ログを見たい../investigations/

Phase 命名規則

  • ファイル名: phase-<N>-<title>/ (例: phase-131/)
  • 文書名: <N>-<NN>-<topic>.md (例: 131-11-case-c-summary.md)
    • Phase 番号で自然にソート可能
    • 同一 Phase 内で段階的に追跡可能

作成ルールSSOT

詳しくは ../DOCS_LAYOUT.md を参照。

  • 置き場所: phases/phase-<N>/ 配下のみ
  • 内容: Phase の実装記録・進捗・チェックリスト・検証結果
  • 避けるべき: 複数 Phase で参照される設計・アーキテクチャ(→ design/ へ)
