From e4eedef34f822dfdb8e4afb7ba033b00d388feee Mon Sep 17 00:00:00 2001 From: nyash-codex Date: Thu, 4 Dec 2025 11:28:55 +0900 Subject: [PATCH] feat(llvm): Phase 132 - Fix PHI instruction ordering bug MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Structural fix for LLVM backend PHI placement issue discovered in Phase 131. Changes: - Modified ensure_phi() to position PHI before existing instructions - Enhanced setup_phi_placeholders() with debug mode - Created phi_placement.py utility for validation - Added test script for representative cases Technical approach: - PHI creation during setup (before block lowering) - Explicit positioning with position_before(instrs[0]) - Debug infrastructure via NYASH_PHI_ORDERING_DEBUG=1 Design principles: - PHI must be created when blocks are empty - finalize_phis only wires, never creates - llvmlite API constraints respected Phase 132 complete. Ready for Phase 133 (ConsoleBox integration). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- CURRENT_TASK.md | 95 ++++++++ .../main/phase132_llvm_phi_ordering.md | 102 +++++++++ src/llvm_py/phi_placement.py | 204 ++++++++++++++++++ src/llvm_py/phi_wiring/tagging.py | 55 ++++- src/llvm_py/phi_wiring/wiring.py | 51 ++++- tools/test_phase132_phi_ordering.sh | 96 +++++++++ 6 files changed, 591 insertions(+), 12 deletions(-) create mode 100644 src/llvm_py/phi_placement.py create mode 100644 tools/test_phase132_phi_ordering.sh diff --git a/CURRENT_TASK.md b/CURRENT_TASK.md index 0e42b2f2..744de979 100644 --- a/CURRENT_TASK.md +++ b/CURRENT_TASK.md @@ -5,6 +5,101 @@ --- +## 🎯 Phase 132: LLVM PHI 命令順序バグ修正（完了）✅ 2025-12-04 + +### 📋 実装内容 + +**目的**: LLVM backend における「PHI 命令の配置順序バグ」を構造的に修正 + +**背景**: +- Phase 131 で LLVM backend re-enable 時に PHI 順序問題を発見 +- LLVM IR では PHI 命令は BasicBlock の **先頭** に配置必須 +- finalize_phis() が terminator（ret/br）の **後** に PHI を配置していた + +### 🔧 修正ファイル + +| ファイル | 修正内容 | 重要度 | +|---------|---------|-------| +| `src/llvm_py/phi_wiring/wiring.py` | ensure_phi() 関数の修正 | ⭐⭐⭐ | +| `src/llvm_py/phi_wiring/tagging.py` | setup_phi_placeholders() 強化 | ⭐⭐⭐ | +| `src/llvm_py/phi_placement.py` | 検証ユーティリティ（新規） | ⭐⭐ | +| `tools/test_phase132_phi_ordering.sh` | テストスクリプト（新規） | ⭐⭐ | + +### 💡 技術的解決策 + +**根本原因**: llvmlite では命令を作成後に移動できない + +**実装アプローチ**: +1. **早期 PHI 生成**: `setup_phi_placeholders` で全 PHI を block lowering 前に生成 +2. **配置位置の明示的制御**: `position_before(instrs[0])` で既存命令より前に配置 +3. **デバッグ機能**: 環境変数 `NYASH_PHI_ORDERING_DEBUG=1` で詳細ログ出力 + +**キーポイント**: +- PHI は block が空の状態で作成するのが最も確実 +- `finalize_phis` は新規 PHI 作成ではなく、既存 PHI への incoming 配線のみ +- llvmlite の API 制約に適合した設計 + +### 📊 期待される動作 + +**修正前** (Phase 131): +```llvm +bb5: + ret i64 %"ret_phi_16" + %"ret_phi_16" = phi i64 [0, %"bb3"], [0, %"bb4"] ;
