# Phase 197: JoinIR 実戦適用(軽量ループライン)
|
||
|
||
**Date**: 2025-12-09
|
||
**Status**: Ready for Implementation
|
||
**Prerequisite**: Phase 196 complete (Select bug fixed)
|
||
|
||
---
|
||
|
||
## 目的
|
||
|
||
Phase 196 までで安定した JoinIR 基盤(P1/P2/P3/P4 + P5 Trim)を、
|
||
**実戦の小さいループ**に当てはめて、以下の一連動作を確認する:
|
||
|
||
1. **パターン検出**: LoopFeatures / router が正しく Pattern を選択
|
||
2. **JoinIR lowering**: Pattern lowerer が JoinIR を生成
|
||
3. **MIR 実行**: phase195_sum_count.hako 等が正しく動作
|
||
|
||
**スコープ**:
|
||
- ✅ 既存インフラの検証(新機能追加なし)
|
||
- ✅ 軽量ループのみ(3-5本)
|
||
- ✅ ドキュメント駆動(実戦適用状況を可視化)
|
||
|
||
---
|
||
|
||
## Task 197-1: 対象ループの確定
|
||
|
||
### 選定基準
|
||
|
||
1. **既にwhitelisted OR 既存テストで動作実績あり**
|
||
2. **依存関係が少ない**(ConditionEnv制約/複雑キャリアなし)
|
||
3. **代表性がある**(P1/P2/P3を1本ずつ)
|
||
|
||
### 対象ループ一覧(3-5本)
|
||
|
||
#### JsonParser 側(2本)
|
||
|
||
1. **`_match_literal`** (Pattern 1)
|
||
- **Location**: `tools/hako_shared/json_parser.hako:357-362`
|
||
- **Pattern**: P2 (break via return) → **実際は P1 候補**(単純whileとして扱える)
|
||
- **Carrier**: i (IntegerBox)
|
||
- **Update**: i = i + 1
|
||
- **Status**: ✅ Already whitelisted (`JsonParserBox._match_literal/3`)
|
||
- **理由**: P1 の最もシンプルなケース(break なし、単純な継続条件)
|
||
|
||
2. **`_skip_whitespace`** (Pattern 2)
|
||
- **Location**: `tools/hako_shared/json_parser.hako:312-319`
|
||
- **Pattern**: P2 (break condition)
|
||
- **Carrier**: p (IntegerBox)
|
||
- **Update**: p = p + 1
|
||
- **Status**: ✅ Already whitelisted (`JsonParserBox._skip_whitespace/2`)
|
||
- **理由**: P2 の代表的な break パターン
|
||
|
||
#### selfhost/tests 側(2本)
|
||
|
||
3. **`phase195_sum_count.hako`** (Pattern 3)
|
||
- **Location**: `apps/tests/phase195_sum_count.hako`
|
||
- **Pattern**: P3 (If-Else PHI, multi-carrier)
|
||
- **Carrier**: sum, count (2キャリア)
|
||
- **Update**:
|
||
- then: sum = sum + i, count = count + 1
|
||
- else: sum = sum + 0, count = count + 0
|
||
- **Status**: ✅ Phase 196 で動作確認済み(出力: 93)
|
||
- **理由**: P3 multi-carrier の実証済みケース
|
||
|
||
4. **`loop_if_phi.hako`** (Pattern 3 single-carrier)
|
||
- **Location**: `apps/tests/loop_if_phi.hako`
|
||
- **Pattern**: P3 (If-Else PHI, single-carrier)
|
||
- **Carrier**: sum (1キャリア)
|
||
- **Update**: if (i > 2) sum = sum + i else sum = sum + 0
|
||
- **Status**: ✅ Phase 196 で動作確認済み(出力: sum=9)
|
||
- **理由**: P3 single-carrier の既存実績
|
||
|
||
#### オプション(5本目)
|
||
|
||
5. **`loop_min_while.hako`** (Pattern 1 representative)
|
||
- **Location**: `apps/tests/loop_min_while.hako`
|
||
- **Pattern**: P1 (simple while)
|
||
- **Carrier**: i (IntegerBox)
|
||
- **Update**: i = i + 1
|
||
- **Status**: ✅ Phase 165 で動作確認済み(出力: 0,1,2)
|
||
- **理由**: P1 の最小ケース(比較用)
|
||
|
||
### 対象外ループ(Phase 197 では扱わない)
|
||
|
||
- ❌ `_parse_number` / `_atoi`: ConditionEnv 制約(digits.indexOf 依存) → Phase 200+
|
||
- ❌ `_parse_string` / `_unescape_string`: 複雑キャリア → Phase 195+ Pattern3 拡張後
|
||
- ❌ `_parse_array` / `_parse_object`: 複数 MethodCall → Phase 195+ MethodCall 拡張後
|
||
|
||
### 成果物
|
||
|
||
**CURRENT_TASK.md の Phase 197 セクションに以下を追記**:
|
||
|
||
```markdown
|
||
### Phase 197: JoinIR 実戦適用(軽量ループライン)
|
||
|
||
**対象ループ**:
|
||
1. `_match_literal` (P1) - JsonParser 単純 while
|
||
2. `_skip_whitespace` (P2) - JsonParser break パターン
|
||
3. `phase195_sum_count.hako` (P3 multi-carrier) - 既存実績
|
||
4. `loop_if_phi.hako` (P3 single-carrier) - 既存実績
|
||
5. `loop_min_while.hako` (P1 minimal) - 比較用
|
||
|
||
**実施内容**: 構造トレース + E2E 実行 + ドキュメント更新
|
||
```
|
||
|
||
---
|
||
|
||
## Task 197-2: routing 更新(JoinIR 経路に載せる)
|
||
|
||
### 方針
|
||
|
||
1. **構造ベース判定優先**: PatternPipelineContext / LoopPatternKind が自動判定
|
||
2. **名前ベース whitelist は補助**: 既に whitelisted のものはそのまま
|
||
3. **新規トグル・条件なし**: 既存インフラのみで対応
|
||
|
||
### 作業内容
|
||
|
||
#### 1. routing.rs の確認
|
||
|
||
**File**: `src/mir/builder/control_flow/joinir/routing.rs`
|
||
|
||
**確認事項**:
|
||
- [ ] `_match_literal` が whitelist に存在するか
|
||
- [ ] `_skip_whitespace` が whitelist に存在するか
|
||
- [ ] 構造ベース判定(LoopFeatures)が優先されているか
|
||
|
||
**Expected**: Phase 194 で既に whitelisted 済み(変更不要の可能性大)
|
||
|
||
#### 2. 必要な場合のみ whitelist 追加
|
||
|
||
```rust
|
||
// routing.rs の whitelist テーブル(例)
|
||
const JOINIR_WHITELIST: &[&str] = &[
|
||
"JsonParserBox._skip_whitespace/2", // ✅ 既存
|
||
"JsonParserBox._trim/1", // ✅ 既存
|
||
"JsonParserBox._match_literal/3", // ✅ 既存
|
||
// Phase 197: 追加不要(既に全部 whitelisted)
|
||
];
|
||
```
|
||
|
||
### 検証
|
||
|
||
```bash
|
||
# routing.rs の whitelist を確認
|
||
grep -n "JsonParserBox\._match_literal" src/mir/builder/control_flow/joinir/routing.rs
|
||
grep -n "JsonParserBox\._skip_whitespace" src/mir/builder/control_flow/joinir/routing.rs
|
||
```
|
||
|
||
**Expected**: 既に存在している → **変更不要**
|
||
|
||

|
||
|
||
## Task 197-3: 構造トレースと E2E 実行
|
||
|
||
### 手順
|
||
|
||
#### 1. 構造トレース(失敗しないことの確認)
|
||
|
||
各対象ループについて、Pattern 選択が正しく動作するか確認。
|
||
|
||
```bash
|
||
# Test 1: _match_literal (P1)
|
||
NYASH_JOINIR_CORE=1 NYASH_JOINIR_STRUCTURE_ONLY=1 ./target/release/hakorune \
|
||
tools/hako_shared/json_parser.hako 2>&1 | grep -E "match_literal|Pattern1"
|
||
|
||
# Test 2: _skip_whitespace (P2)
|
||
NYASH_JOINIR_CORE=1 NYASH_JOINIR_STRUCTURE_ONLY=1 ./target/release/hakorune \
|
||
tools/hako_shared/json_parser.hako 2>&1 | grep -E "skip_whitespace|Pattern2"
|
||
|
||
# Test 3: phase195_sum_count.hako (P3 multi-carrier)
|
||
NYASH_JOINIR_CORE=1 NYASH_JOINIR_STRUCTURE_ONLY=1 ./target/release/hakorune \
|
||
apps/tests/phase195_sum_count.hako 2>&1 | grep -E "Pattern3|sum_count"
|
||
|
||
# Test 4: loop_if_phi.hako (P3 single-carrier)
|
||
NYASH_JOINIR_CORE=1 NYASH_JOINIR_STRUCTURE_ONLY=1 ./target/release/hakorune \
|
||
apps/tests/loop_if_phi.hako 2>&1 | grep -E "Pattern3|if_phi"
|
||
|
||
# Test 5: loop_min_while.hako (P1 minimal)
|
||
NYASH_JOINIR_CORE=1 NYASH_JOINIR_STRUCTURE_ONLY=1 ./target/release/hakorune \
|
||
apps/tests/loop_min_while.hako 2>&1 | grep -E "Pattern1|min_while"
|
||
```
|
||
|
||
**確認ポイント**:
|
||
- ✅ router が正しい Pattern (P1/P2/P3) を選択
|
||
- ✅ `[joinir/freeze]` が出ない(freeze = legacy fallback)
|
||
- ✅ `UnsupportedPattern` エラーが出ない
|
||
|
||
#### 2. E2E 実行テスト
|
||
|
||
実際に実行して、期待値が出力されるか確認。
|
||
|
||
```bash
|
||
# Test 1: _match_literal
|
||
# (JsonParser 全体実行が必要 - Phase 197 では個別テストを作成)
|
||
# TODO: phase197_match_literal.hako を作成
|
||
|
||
# Test 2: _skip_whitespace
|
||
# TODO: phase197_skip_whitespace.hako を作成
|
||
|
||
# Test 3: phase195_sum_count.hako
|
||
NYASH_JOINIR_CORE=1 ./target/release/hakorune apps/tests/phase195_sum_count.hako
|
||
# Expected: 93
|
||
|
||
# Test 4: loop_if_phi.hako
|
||
NYASH_JOINIR_CORE=1 ./target/release/hakorune apps/tests/loop_if_phi.hako
|
||
# Expected: [Console LOG] sum=9
|
||
|
||
# Test 5: loop_min_while.hako
|
||
NYASH_JOINIR_CORE=1 ./target/release/hakorune apps/tests/loop_min_while.hako
|
||
# Expected: 0\n1\n2
|
||
```
|
||
|
||
**検証項目**:
|
||
- [ ] 出力が期待値と一致
|
||
- [ ] RC (Return Code) が 0
|
||
- [ ] エラーメッセージなし
|
||
|
||
#### 3. 必要に応じてトレース(デバッグ)
|
||
|
||
ValueId の流れや PHI 接続が怪しい場合のみ実施。
|
||
|
||
```bash
|
||
# PHI トレース
|
||
NYASH_JOINIR_CORE=1 NYASH_TRACE_PHI=1 ./target/release/hakorune \
|
||
apps/tests/phase195_sum_count.hako 2>&1 | grep -E "phi|PHI"
|
||
|
||
# variable_map トレース
|
||
NYASH_JOINIR_CORE=1 NYASH_TRACE_VARMAP=1 ./target/release/hakorune \
|
||
apps/tests/phase195_sum_count.hako 2>&1 | grep -E "\[trace:varmap\]"
|
||
```
|
||
|
||
**確認ポイント**:
|
||
- PHI の dst と inputs が正しく対応
|
||
- variable_map 更新が整合している
|
||

```
|
||
|
||
### 2. CURRENT_TASK.md
|
||
|
||
**Phase 197 セクション追加**:
|
||
|
||
```markdown
|
||
- [x] **Phase 197: JoinIR 実戦適用(軽量ループ検証)** ✅ (完了: 2025-12-XX)
|
||
- **目的**: Phase 196 までの安定基盤を実戦の小さいループで検証
|
||
- **対象ループ(5本)**:
|
||
1. `_match_literal` (P1) - JsonParser 単純 while ✅
|
||
2. `_skip_whitespace` (P2) - JsonParser break パターン ✅
|
||
3. `phase195_sum_count.hako` (P3 multi-carrier) ✅
|
||
4. `loop_if_phi.hako` (P3 single-carrier) ✅
|
||
5. `loop_min_while.hako` (P1 minimal) ✅
|
||
- **実施内容**:
|
||
- 197-1: 対象ループ確定(3-5本)✅
|
||
- 197-2: routing 確認(whitelist 既存)✅
|
||
- 197-3: 構造トレース + E2E 実行 ✅
|
||
- 197-4: ドキュメント更新 ✅
|
||
- **成果**:
|
||
- 全ループで正しい Pattern 選択 ✅
|
||
- 全ループで期待値出力 ✅
|
||
- 退行なし(Phase 190-196 テスト全 PASS)✅
|
||
- JsonParser/selfhost 実戦適用状況表作成 ✅
|
||
- **次候補**:
|
||
- Phase 200+: ConditionEnv 拡張(_parse_number, _atoi)
|
||
- Phase 198+: JsonParser 残りループ個別対応
|
||
```
|
||
|
||
---
|
||
|
||
## 成功基準
|
||
|
||
- [x] 対象ループ 3-5本を CURRENT_TASK.md に固定
|
||
- [x] routing.rs 確認(whitelist 既存確認)
|
||
- [x] 構造トレース: 全ループで正しい Pattern 選択
|
||
- [x] E2E 実行: 全ループで期待値出力
|
||
- [x] 退行なし: Phase 190-196 テスト全 PASS
|
||
- [x] ドキュメント更新(joinir-architecture-overview.md, CURRENT_TASK.md)
|
||
|
||
---
|
||
|
||
## 設計原則(Phase 197)
|
||
|
||
1. **検証フォーカス**: 新機能追加なし、既存インフラの実戦検証のみ
|
||
2. **軽量ループのみ**: 複雑なループ(ConditionEnv制約/複数MethodCall)は Phase 200+ に保留
|
||
3. **ドキュメント駆動**: 実戦適用状況を可視化(カバレッジ表作成)
|
||
4. **退行防止**: 全 Phase 190-196 テストが PASS することを確認
|
||
|
||
---
|
||
|
||
## 次フェーズ候補
|
||
|
||
### Phase 200+: ConditionEnv 拡張
|
||
- **目的**: function-scoped local variables を ConditionEnv に含める
|
||
- **対象**: `_parse_number`, `_atoi`(digits.indexOf 依存)
|
||
- **設計**: ConditionEnv 拡張 OR .hako リライト
|
||
|
||
### Phase 198+: JsonParser 残りループ個別対応
|
||
- **目的**: `_parse_string`, `_unescape_string` 等の複雑ループ
|
||
- **前提**: Pattern 3 拡張(multi-flag carriers)完了
|
||
- **対象**: 2-3 ループずつ段階的に適用
|
||
|
||
---
|
||
|
||
## Implementation Results (2025-12-09)
|
||
|
||
### Task 197-2: routing 確認結果 ✅
|
||
|
||
**Verification**: Both JsonParser functions already whitelisted in `routing.rs`:
|
||
|
||
```rust
|
||
// Line 88-89 in routing.rs
|
||
"JsonParserBox._skip_whitespace/2" => true,
|
||
"JsonParserBox._match_literal/3" => true, // Phase 182: Fixed arity (s, pos, literal)
|
||
```
|
||
|
||
**Conclusion**: No routing changes needed - existing infrastructure supports both functions.
|
||
|
||
