refactor(joinir): unify boundary join_inputs SSOT (pattern4/6/7)
Apply Phase 256.8 SSOT fix to Pattern4/6/7: - Use join_module.entry.params.clone() instead of hardcoded ValueIds - Add fail-fast validation for params count mismatch - Remove ValueId(0), ValueId(PARAM_MIN + k) patterns - Clean up unused PARAM_MIN imports This prevents entry_param_mismatch errors structurally and maintains consistency with Pattern2/3. Changes: - pattern4_with_continue.rs: Lines 442-476 (SSOT extraction + validation) - pattern6_scan_with_init.rs: Lines 447-471 (SSOT extraction + validation) - pattern7_split_scan.rs: Lines 495-526 (SSOT extraction + validation) All patterns now use the same SSOT principle: 1. Extract entry function (priority: join_module.entry → fallback "main") 2. Use params as SSOT: join_inputs = entry_func.params.clone() 3. Build host_inputs in expected order (pattern-specific) 4. Fail-fast validation: join_inputs.len() == host_inputs.len() Verification: - cargo build --release: ✅ PASS (no PARAM_MIN warnings) - Quick profile: ✅ First FAIL still json_lint_vm (baseline maintained) - Pattern6 smoke: ✅ PASS (index_of test) - Pattern7 smoke: Pre-existing phi pred mismatch (not introduced by SSOT) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

# Phase 257 Investigation: `last_index_of/2` loop shape
|
||||
|
||||
## Symptom（SSOT）
|
||||
|
||||
`./tools/smokes/v2/run.sh --profile quick` の最初の FAIL:
|
||||
|
||||
- `json_lint_vm` が `StringUtils.last_index_of/2` で停止
|
||||
- エラー: `[joinir/freeze] Loop lowering failed: JoinIR does not support this pattern, and LoopBuilder has been removed.`
|
||||
|
||||
## Minimal Fixture
|
||||
|
||||
- `apps/tests/phase257_p0_last_index_of_min.hako`
|
||||
|
||||
形（要旨）:
|
||||
|
||||
```nyash
|
||||
local i = s.length() - 1
|
||||
loop(i >= 0) {
|
||||
if s.substring(i, i + 1) == ch { return i }
|
||||
i = i - 1
|
||||
}
|
||||
return -1
|
||||
```
|
||||
|
||||
## StepTree / Capabilities（ログ観測）
|
||||
|
||||
（実ログは `tools/smokes/v2/profiles/quick/apps/json_lint_vm.sh` の tail を参照）
|
||||
|
||||
- caps: `If,Loop,Return`（break/continue なし）
|
||||
- loop cond: `i >= 0`
|
||||
- step: `i = i - 1`（const step のはず）
|
||||
- early exit: `return i`
|
||||
- not-found: `return -1`
|
||||
|
||||
`loop_canonicalizer` は `Missing caps: [ConstStep]` で FAIL_FAST しているが、ここは “Pattern2 側の試行ログ” であり、
|
||||
JoinIR パターンがこの形を受理できていないのが本体。
|
||||
|
||||
## Root Cause Hypothesis（現状の仮説）
|
||||
|
||||
- Pattern6（ScanWithInit）が forward scan 前提（`i = i + 1`, `i < bound`）で、reverse scan を検出できていない。
|
||||
- Pattern7（SplitScan）は適用対象外。
|
||||
- Pattern3/1 は `return` を含む loop を扱わない（or 目的が違う）。
|
||||
|
||||
## Decision（Phase 257 の方針）
|
||||
|
||||
Phase 257 では、以下で進める:
|
||||
|
||||
- Pattern6（ScanWithInit）を “scan direction” 付きに一般化し、reverse scan + early return を受理する。
|
||||
- Phase 256 で固めた Contract（`JumpArgsLayout`, pipeline contract checks）に従い、merge 側で推測しない。
|
||||
|
||||
## Questions（将来に残す設計論点）
|
||||
|
||||
1. `LoopPatternKind` に Pattern6/7 を増やすべきか？（router 側での分類SSOTを揃える）
|
||||
2. scan 系の “forward/reverse” を 1 パターンにまとめるか、専用 Pattern を増やすか？
|
||||
3. `return` を loop 語彙として Pattern 側で扱い続けるか、Normalization で “early exit” に正規化すべきか？

## 進捗（P1.13）
|

|
||||
### P1.13: Pattern2 boundary entry_param_mismatch 根治（完了）
|
||||
|
||||
症状（json_lint_vm / StringUtils.trim_end/1）:
|
||||
```
|
||||
[ERROR] ❌ MIR compilation error: [joinir/phase1.5/boundary/entry_param_mismatch]
|
||||
Entry param[0] in 'main': expected ValueId(1000), but boundary.join_inputs[0] = ValueId(0)
|
||||
Hint: parameter ValueId mismatch indicates boundary.join_inputs constructed in wrong order
|
||||
```
|
||||
|
||||
根本原因（SSOT）:
|
||||
- `emit_joinir_step_box.rs` が `boundary.join_inputs` を hardcoded ValueId(0), ValueId(1)... で構築していた
|
||||
- JoinIR lowerer は `alloc_param()` / `alloc_local()` で実際のパラメータ ValueId を割り当てている
|
||||
- 両者が一致しないため、boundary contract check で fail-fast
|
||||
|
||||
修正方針（SSOT原則）:
|
||||
- **SSOT**: `join_module.entry.params` が `boundary.join_inputs` の唯一の真実
|
||||
- **禁止**: ValueId(0..N) の推測生成、Param/Local 領域の決めつけ、JoinModule とは独立に ValueId を作ること
|
||||
- **実装**: `emit_joinir_step_box.rs` で `join_input_slots = entry_func.params.clone()` に置き換え
|
||||
|
||||
実装（SSOT）:
|
||||
- `src/mir/builder/control_flow/joinir/patterns/pattern2_steps/emit_joinir_step_box.rs` (lines 71-96)
|
||||
- Entry function extraction (priority: `join_module.entry` → fallback to "main")
|
||||
- `join_input_slots = main_func.params.clone()` (SSOT from JoinModule)
|
||||
- `host_input_values` を同じ順序で構築（loop_var + carriers）
|
||||
- Fail-fast validation for params count mismatch
|
||||
|
||||
結果:
|
||||
- `./tools/smokes/v2/run.sh --profile quick` の first FAIL が `StringUtils.trim_end/1` から `StringUtils.last_index_of/2` へ移動
|
||||
- Pattern2 の boundary contract は安定化
|
||||
|
||||
次のブロッカー（Phase 257）:
|
||||
- `StringUtils.last_index_of/2` - Loop with early return pattern (unsupported)
|
||||
- Structure: `loop(i >= 0) { if (cond) { return value } i = i - 1 } return default`
|
||||
- Capabilities: `caps=If,Loop,Return` (no Break)
|
||||
- Missing: ConstStep capability
|
||||
- Approach: Extend Pattern2 to handle return (similar to break) or create Pattern2Return variant
|
||||
- Fixture: `apps/tests/phase257_p0_last_index_of_min.hako`
|
||||
- Integration smokes: `phase257_p0_last_index_of_vm.sh`, `phase257_p0_last_index_of_llvm_exe.sh`
|
||||
|
||||
次（P1.5 Task 3）:
|
||||
- `ValueId(57)` が「何の JoinIR 値の remap 結果か」を確定し、定義側（dst）が MIR に落ちているかを追う
|
||||
- 例: `sep_len = sep.length()` の BoxCall dst が収集/変換/順序のどこかで欠けていないか

|
||||
|
||||
### 期待される動作
|
||||
|
||||
`StringUtils.last_index_of(s, ch)` が正常にコンパイルされ、文字列内の最後の文字位置を返すこと。
|
||||
|
||||
### 実際の動作
|
||||
|
||||
Loop canonicalizer が `ConstStep` を要求しているが、このループは早期リターンを持つため Pattern2Break として認識されていない。
|
||||
|
||||
### 最小再現コード
|
||||
|
||||
```nyash
|
||||
// apps/tests/phase257_p0_last_index_of_min.hako
|
||||
static box Main {
|
||||
main() {
|
||||
local s = "hello world"
|
||||
local ch = "o"
|
||||
|
||||
// Find last occurrence of ch in s
|
||||
local i = s.length() - 1
|
||||
|
||||
loop(i >= 0) {
|
||||
if s.substring(i, i + 1) == ch {
|
||||
return i // Early return when found
|
||||
}
|
||||
i = i - 1 // Backward scan
|
||||
}
|
||||
|
||||
return -1 // Not found
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 分析
|
||||
|
||||
#### ループ構造
|
||||
|
||||
1. **条件**: `i >= 0` (backward scan)
|
||||
2. **ボディ**:
|
||||
- If branch: マッチング検出時
|
||||
- `return i` で早期リターン
|
||||
- After if: マッチなし
|
||||
- `i = i - 1` で 1 つ戻る（定数ステップ）
|
||||
3. **特徴**:
|
||||
- **Early return**: break ではなく return を使用
|
||||
- **Backward scan**: `i--` で逆方向スキャン
|
||||
- **Capabilities**: `caps=If,Loop,Return` (no Break)
|
||||
- **Exits**: `exits=return` (両方の return を検出)
|
||||
|
||||
#### Pattern6（index_of）との比較
|
||||
|
||||
| Feature | Pattern6/index_of | last_index_of |
|
||||
|---------|-------------------|---------------|
|
||||
| 走査方向 | forward（`i = i + 1`） | reverse（`i = i - 1`） |
|
||||
| 早期終了 | 見つかったら return / exit PHI | 見つかったら return |
|
||||
| 通常終了 | not-found return（例: `-1`） | not-found return（`-1`） |
|
||||
| JoinIR | `main/loop_step/k_exit` | 同じ語彙で表現できる |
|
||||
|
||||
#### 提案される実装アプローチ
|
||||
|
||||
**Option A: Pattern6 拡張（推奨 / 最小差分）**
|
||||
|
||||
Pattern6（ScanWithInit）を “scan direction” を持つ形に一般化する（forward / reverse）。
|
||||
|
||||
1. **検出条件**:
|
||||
- init: `i = s.length() - 1`（reverse）または `i = 0`（forward）
|
||||
- loop cond: `i >= 0`（reverse）または `i < bound`（forward）
|
||||
- body: `if s.substring(i, i + 1) == ch { return i }` + step update
|
||||
- step: `i = i - 1`（reverse const step）または `i = i + 1`（forward const step）
|
||||
|
||||
2. **JoinIR lowering**:
|
||||
- Pattern6 の語彙（`main/loop_step/k_exit`）を維持
|
||||
- scan direction に応じて:
|
||||
- stop 判定（`i < 0` or `i >= bound`）
|
||||
- const step（`+1` / `-1`）
|
||||
- return は既存の “exit PHI + post-loop guard” を必要最小で再利用する（DCE回避は既存Box優先）
|
||||
|
||||
3. **Boundary construction**:
|
||||
- Phase 256 系の契約（`JumpArgsLayout` / contract checks）に従い、推測しない
|
||||
- `expr_result` は `return i` の経路でのみ使用（not-found は `-1`）
|
||||
|
||||
**Option B: Pattern8_ReverseScanReturn 新設**
|
||||
|
||||
Pattern6 を触らずに、reverse scan 専用パターンとして箱を追加する。
|
||||
（影響範囲は狭いが、scan 系が分裂する）
|
||||
|
||||
**Option C: Normalization（将来）**
|
||||
|
||||
return/break を正規化して共通語彙へ落とし、JoinIR patterns を縮退させる。
|
||||
（Phase 257 ではやらない）
|
||||
|
||||
### 実装計画
|
||||
|
||||
#### 推奨方針
|
||||
|
||||
**Option A**（Pattern6 拡張）を推奨。
|
||||
|
||||
理由:
|
||||
- 既に index_of/find 系で “scan + not-found return” を Pattern6 が担っている
|
||||
- last_index_of はその自然な派生（reverse scan + const step -1）
|
||||
- Pattern2（break 前提）を膨らませずに済む
|
||||
|
||||
#### P0 タスク

||||

||||
- `src/mir/builder/control_flow/joinir/patterns/pattern6_scan_with_init.rs`
|
||||
- reverse scan 形を accept し、parts（init/cond/step/return/not-found）を抽出
|
||||
|
||||
3) **Pattern6 lowerer 拡張**
|
||||
- reverse scan の stop 判定・step を JoinIR へ落とす（語彙は既存 Pattern6 を維持）
|
||||
|
||||
4) **検証**
|
||||
- `bash tools/smokes/v2/profiles/integration/apps/phase257_p0_last_index_of_vm.sh`
|
||||
- `./tools/smokes/v2/run.sh --profile quick`（最初の FAIL が次へ進む）
|
||||
|
||||
### 注意（P0ではやらない）
|
||||
|
||||
- 正規化での return/break 統一（Phase 257 ではやらない）
|
||||
- scan 系の大改造（まずは reverse scan の受理を最小差分で固定）
|
||||
|
||||
---
|
||||
|
||||
## 備考
|
||||
|
||||
- Phase 256 で Pattern2Break の境界構築が SSOT 化済み（entry_param_mismatch 根治）
|
||||
- この知見を活かし、Pattern2Return も同じ原則で実装する
|
||||
- "Early exit" として break と return を統一的に扱うことで、将来の拡張性も高まる
|
||||
|
||||
---
|
||||
|
||||
## 進捗（P0）
|
||||
|
||||
### 次のステップ
|
||||
|
||||
1. Pattern6 の forward scan parts と差分を整理（init/cond/step/return）
|
||||
2. reverse scan の extractor を実装（Fail-Fast）
|
||||
3. JoinIR lowerer へ reverse scan を追加（既存 contract に従う）
|
||||
4. integration smokes + quick profile を回して SSOT 更新
