feat(phase131): LLVM backend re-enable & PHI ordering bug discovery
Phase 131: JoinIR → LLVM individual fixes (minimal scope)
## Modifications
### 1. LLVM Backend Re-enable ✅
- Built with --features llvm to enable real LLVM execution
- Verified Python/llvmlite environment (llvmlite 0.45.1)
- Fixed llvmlite deprecated API: removed llvm.initialize() call
- Successfully moved from Mock backend to real LLVM harness execution
### 2. PHI Instruction Ordering Bug Discovery ⚠️
- Discovered critical bug: PHI nodes placed AFTER terminator instructions
- LLVM IR constraint: PHI must be at block start, before any non-PHI
- Root cause: finalize_phis() in llvm_builder.py emits PHIs after block termination
- Affects all 6 tests with control flow merges
### 3. ConsoleBox LLVM Integration ⚠️
- Confirmed ConsoleBox not registered in Rust VM environment
- Deferred to Phase 132 (prerequisite issue)
## Results
Modified files:
- src/llvm_py/llvm_builder.py: Removed deprecated llvm.initialize()
- docs/development/current/main/phase130_joinir_llvm_baseline.md: Added Phase 131 results
- CURRENT_TASK.md: Added Phase 131 completion report
Test results:
- ✅ peek_expr_block.hako: LLVM execution success (Result: 1)
- ❌ 6/7 tests: PHI ordering bug (requires Phase 132 refactoring)
## Success Criteria
- ✅ LLVM backend minimal re-enable (1/7 test passing)
- ⚠️ PHI ordering bug discovered and documented
- ⚠️ ConsoleBox integration deferred to Phase 132
## Phase 132 Handoff
Priority 1: Fix PHI instruction ordering bug (finalize_phis() refactoring)
Priority 2: Resolve ConsoleBox registration issue
Priority 3: Enable remaining test cases for LLVM

docs(phase130): JoinIR→LLVM ベースライン確立
Phase 130完了: JoinIR → LLVM 経路の現状を観測・記録
実施内容:
- 代表ケース7本選定（selfhost/hako_check/JoinIR各系統）
- Rust VM / LLVM harness 両経路でテスト実行
- 実行結果を表形式で記録（観測専用、修正なし）
- Phase 131への引き継ぎ事項を整理
テスト結果:
- Rust VM: 6/7 PASS (85.7%)
- peek_expr_block, loop_min_while, phase123_simple_if,
phase123_while_loop, joinir_if_select_simple, joinir_min_loop
- FAIL: esc_dirname_smoke (ConsoleBox未登録)
- LLVM harness: 0/7実行 (Mock backend、要--features llvm)
- MIRコンパイルは全て成功
- 実LLVM実行は未対応
検出された問題点:
1. LLVM Backend未対応（最重要）
- --features llvm ビルドが必要
- Mock backend実行中
2. ConsoleBox未登録問題
- Rust VM環境での登録不備
- Phase 15.5方針との衝突
3. JoinIR → LLVM経路の不明確性
- MIR → LLVM IR lowering未検証
成果物:
- docs/development/current/main/phase130_joinir_llvm_baseline.md
- 代表ケース選定理由・実行コマンド整理
- 実行結果詳細・問題点分析
- Phase 131引き継ぎ事項
- CURRENT_TASK.md: Phase 130セクション追加
- 30-Backlog.md: Phase 131予告追加
次フェーズ: Phase 131 - JoinIR→LLVM 個別修正ライン
