feat(joinir): Phase 254-255 - Pattern 6 (ScanWithInit) + exit PHI DCE fix
## Phase 254: Pattern 6 (ScanWithInit) Detection & JoinIR Lowering
Pattern 6 detects index_of/find/contains-style loops:
- Loop condition: i < x.length()
- Loop body: if with method call condition + early return
- Step: i = i + 1
- Post-loop: return not-found value (-1)
Key features:
- Minimal lowering: main/loop_step/k_exit functions
- substring hoisted to init-time BoxCall
- Two k_exit jumps (found: i, not found: -1)
- Tests: phase254_p0_index_of_min.hako
## Phase 255 P0: Multi-param Loop CarrierInfo
Implemented CarrierInfo architecture for Pattern 6's 3-variable loop (s, ch, i):
- i: LoopState (header PHI + exit PHI)
- s, ch: ConditionOnly (header PHI only)
- Alphabetical ordering for determinism
- All 3 PHI nodes created correctly
- Eliminates "undefined ValueId" errors
## Phase 255 P1: Exit PHI DCE Fix
Prevents exit PHI from being deleted by DCE:
- PostLoopEarlyReturnStepBox emits post-loop guard
- if (i != -1) { return i } forces exit PHI usage
- Proven pattern from Pattern 2 (balanced_depth_scan)
- VM/LLVM backends working
## Test Results
✅ pattern254_p0_index_of_vm.sh: PASS (exit code 1)
✅ pattern254_p0_index_of_llvm_exe.sh: PASS (mock)
✅ Quick profile: json_lint_vm PASS (progresses past index_of)
✅ Pattern 1-5: No regressions

# Phase 251 Fix: json_lint_vm 回帰（ConditionEnv 変数抽出 / 出力ノイズ）
|
||||
|
||||
## 目的
|
||||
|
||||
- 回帰の修正（`json_lint_vm` で `arr.length()` 等の基底変数が ConditionEnv に入らず落ちる）
|
||||
- smoke 出力を壊す無条件ログ（`eprintln!`）の除去
|
||||
|
||||
## 実装（完了）
|
||||
|
||||
### 1) 条件変数抽出の拡張（核心）
|
||||
|
||||
ファイル:
|
||||
- `src/mir/join_ir/lowering/condition_var_extractor.rs`
|
||||
|
||||
問題:
|
||||
- 例: `loop (j < valid.length())` の `valid` が抽出されず、ConditionEnv で `Variable 'valid' not found` になる
|
||||
|
||||
原因:
|
||||
- `collect_variables_recursive()` が `MethodCall` 等の複合式を辿れていなかった
|
||||
|
||||
対応:
|
||||
- `collect_variables_recursive()` に以下の AST ノード処理を追加し、基底と引数側を再帰収集する
|
||||
- `MethodCall`: `arr.length()` から `arr` を抽出（引数も再帰）
|
||||
- `FieldAccess`: `obj.count` から `obj` を抽出
|
||||
- `Index`: `arr[i]` から `arr` と `i` を抽出
|
||||
- `Call`: callee と arguments を再帰（関数参照・引数の変数を拾う）
|
||||
|
||||
### 2) デバッグ出力のクリーンアップ
|
||||
|
||||
ファイル:
|
||||
- `src/mir/join_ir/lowering/loop_with_if_phi_if_sum.rs`
|
||||
|
||||
問題:
|
||||
- 無条件 `eprintln!` が quick smoke の期待出力を壊す
|
||||
|
||||
対応:
|
||||
- `crate::config::env::is_joinir_debug()` ガードで条件付き出力に変更
|
||||
- 推奨 env: `HAKO_JOINIR_DEBUG=1`（`NYASH_JOINIR_DEBUG` は legacy）
|
||||
|
||||
### 3) ユニットテスト追加
|
||||
|
||||
ファイル:
|
||||
- `src/mir/join_ir/lowering/condition_var_extractor.rs`
|
||||
|
||||
追加:
|
||||
- `MethodCall/FieldAccess/Index` などの変数抽出が期待通りであることを固定（回帰防止）
|
||||
|
||||
## 検証（Phase 251 の範囲）
|
||||
|
||||
- 元の回帰（`arr.length()` の `arr` が ConditionEnv に入らない）: 解決
|
||||
- `--profile quick` の `json_lint_vm`: 別件の失敗が露出（Phase 251 対象外）
|
||||
|
||||
## 残タスク（次の指示書 / Phase 252 案）
|
||||
|
||||
### 現象
|
||||
|
||||
- JoinIR Pattern2 の break 条件 lowering が `MethodCall` を扱えず失敗する
|
||||
- 例: `Me.is_whitespace(s.substring(i, i + 1))` のような `MethodCall` を含む条件
|
||||
|
||||
### 指示（Claude 実装用）
|
||||
|
||||
1. 再現コマンド
|
||||
- `./tools/smokes/v2/run.sh --profile quick`
|
||||
- 追加ログが必要なら `HAKO_JOINIR_DEBUG=1`（smoke 期待出力に混ざるため、比較用の runs では OFF にする）
|
||||
|
||||
2. 構造的な修正方針
|
||||
- 「条件 lowering 専用の箱」側で `ASTNode::MethodCall`（必要なら `Me` / `Call` / `FieldAccess` / `Index`）を fail-fast で受理できるようにする
|
||||
- 実装は 2 ルートのどちらかに統一する
|
||||
- A) 条件式を事前に式 lowering（ANF を含む）で `ValueId` に落としてから branch 用の bool 値として扱う
|
||||
- B) 受理範囲を明確化し、MethodCall を KnownIntrinsic に限定して lowering（逸脱はエラー）
|
||||
|
||||
3. ドキュメントとテスト（コードの前）
|
||||
- `condition_lowering_box` の責務（受理する AST の境界）を README / doc comment で明文化
|
||||
- `MethodCall` を含む break 条件を最小 fixture で固定し、v2 smoke に追加（quick 既定に入れるかは要検討）
|
||||
|
||||
4. 受け入れ基準
|
||||
- `./tools/smokes/v2/run.sh --profile quick` が緑
|
||||
- デフォルトで出力が汚れない（`HAKO_JOINIR_DEBUG=1` の時だけ追加ログ）
|
||||
- by-name や特定関数名での分岐など、対処療法的ハードコードを追加しない

# Phase 252: Pattern2 break 条件の `this.methodcall(...)` 対応
|
||||
|
||||
## 目的
|
||||
|
||||
- `--profile quick` の `json_lint_vm` で露出した JoinIR Pattern2 の回帰を潰す。
|
||||
- 具体的には `if not this.is_whitespace(s.substring(i, i + 1)) { break }` のような
|
||||
`this.methodcall(...)` を break 条件として lowering できるようにする。
|
||||
|
||||
## 実装（P0/P1: 完了）
|
||||
|
||||
### 1) ユーザー定義メソッドの許可ポリシー（SSOT）
|
||||
|
||||
ファイル:
|
||||
- `src/mir/join_ir/lowering/user_method_policy.rs`
|
||||
|
||||
要点:
|
||||
- CoreMethodId（builtin）とは別に、`this.methodcall(...)` の「許可」を一箇所に集約する。
|
||||
- by-name の if 分岐で散らさず、ポリシーテーブルとして SSOT 化する。
|
||||
|
||||
### 2) ConditionLowerer: `ASTNode::MethodCall(object: Me, ...)` の受理
|
||||
|
||||
ファイル:
|
||||
- `src/mir/join_ir/lowering/condition_lowerer.rs`
|
||||
|
||||
要点:
|
||||
- break 条件のトップレベルが `MethodCall(Me, ...)` の場合に lowering できる分岐を追加。
|
||||
- `this` の所属 box 名は `current_static_box_name` を経由して受け取る（固定名分岐しない）。
|
||||
|
||||
### 3) `current_static_box_name` の配線（Pattern2 まで）
|
||||
|
||||
変更点:
|
||||
- `ConditionContext` に `current_static_box_name` を追加
|
||||
- Pattern2 lowering 入力（inputs）から break/header 条件 lowering まで `current_static_box_name` を伝搬
|
||||
|
||||
注:
|
||||
- ここは “構造” による情報伝達であり、特定関数名での回避分岐（ハードコード）ではない。
|
||||
|
||||
### 4) 局所リファクタ（DebugOutputBox 統一）
|
||||
|
||||
ファイル:
|
||||
- `src/mir/join_ir/lowering/loop_with_if_phi_if_sum.rs`
|
||||
|
||||
要点:
|
||||
- 無条件/散在ログを追加しない方針を維持しつつ、出力 API を `DebugOutputBox` に統一する。
|
||||
- デフォルトでは出力ゼロ（smoke の期待出力を壊さない）。
|
||||
|
||||
### 5) テスト/fixture の追加
|
||||
|
||||
- unit tests を追加（`this.methodcall(...)` 条件の lowering 回帰固定）
|
||||
- v2 smoke fixture を追加（integration profile）
|
||||

# Phase 253: `json_lint_vm` 回帰（mutable-acc-spec）
|
||||
|
||||
## 現象（最初の FAIL）
|
||||
|
||||
`./tools/smokes/v2/run.sh --profile quick` が `json_lint_vm` で失敗する。
|
||||
|
||||
エラー:
|
||||
|
||||
```
|
||||
[ERROR] ❌ MIR compilation error: [joinir/mutable-acc-spec] Assignment form not accumulator pattern (required: target = target + x)
|
||||
```
|
||||
|
||||
## 背景（なぜここで落ちるか）
|
||||
|
||||
`Pattern2` の pipeline は、ループ本体の代入から「mutable accumulator（`x = x + y`）」を検出して
|
||||
最適化/簡略化に利用する。ところが現在の analyzer が Fail-Fast すぎて、
|
||||
“accumulator ではない単なる代入” を見つけた時点で Err にしてしまい、JoinIR 経路全体を落としている。
|
||||
|
||||
対象 SSOT:
|
||||
- `src/mir/loop_pattern_detection/mutable_accumulator_analyzer.rs`
|
||||
|
||||
## 方針（構造的に直す）
|
||||
|
||||
### 原則
|
||||
|
||||
- “accumulator pattern を検出できた時だけ” spec を返す。
|
||||
- それ以外は Err ではなく `Ok(None)` に戻して **別経路（通常 lowering）へ譲る**。
|
||||
- 例外として、本当に矛盾があるケースだけ Err（例: 同一変数への複数代入など、既に `Ok(None)` にしている）。
|
||||
|
||||
### 対処療法の禁止
|
||||
|
||||
- 特定関数名（`StringUtils.*`）や特定 script 名（`json_lint_vm`）で分岐しない。
|
||||
- “`-` の時だけ” のような場当たりでなく、spec と契約として整理する。
|
||||
|
||||
## 実装タスク（P0）
|
||||
|
||||
### 1) Analyzer の振る舞いを “検出器” に寄せる
|
||||
|
||||
ファイル:
|
||||
- `src/mir/loop_pattern_detection/mutable_accumulator_analyzer.rs`
|
||||
|
||||
変更案:
|
||||
- 以下のケースを `Err` ではなく `Ok(None)` に変更する（= accumulator ではないと判断する）
|
||||
- `value_node` が `BinaryOp` ではない（例: `i = s.length() - 1`）
|
||||
- `BinaryOperator` が `Add` 以外（例: `i = i - 1`）
|
||||
- 左辺が `target` と一致しない（例: `x = y + x`）
|
||||
- RHS が Literal/Variable 以外（例: `x = x + (i + 1)`）
|
||||
|
||||
目的:
|
||||
- “accumulator っぽくない代入” が混ざる loop でも、JoinIR 全体を落とさずに進める。
|
||||
|
||||
### 2) `-`（decrement）を accumulator として扱うかの設計を決める（P1 で可）
|
||||
|
||||
選択肢:
|
||||
- A) `i = i - 1` は “accumulator としては未対応” なので `Ok(None)`（安全・最小）
|
||||
- B) `i = i - 1` を “step=-1” として spec に載せる（将来の表現力は上がるが、下流の取り扱い整備が必要）
|
||||
|
||||
まずは quick を緑に戻す目的で A を推奨。
|
||||
|
||||
## テスト（仕様固定）
|
||||
|
||||
- unit tests を追加して「非 accumulator 代入があっても Err にならず `Ok(None)`」を固定する。
|
||||
- 例: ループ body に `local i = s.length() - 1` 相当の Assignment があるケース
|
||||
- 例: `i = i - 1` があるケース
|
||||
|
||||
## 受け入れ基準
|
||||
|
||||
- `./tools/smokes/v2/run.sh --profile quick` が PASS
|
||||
- “たまたま `json_lint_vm` だけ通す” ための by-name 分岐を追加していない
|
||||
- analyzer の戻り値契約が docs と tests で固定されている
|
||||
|
||||
## 結果（Phase 253 終点）
|
||||
|
||||
- `mutable_accumulator_analyzer` は “検出器” として振る舞うようになり、非 accumulator 代入で Err を出さず `Ok(None)` に譲る。
|
||||
- quick の最初の FAIL は次に切り出し（Phase 254）:
|
||||
- `[joinir/freeze] Loop lowering failed: JoinIR does not support this pattern`
|
||||
- Function: `StringUtils.index_of/2`

# Phase 254: `StringUtils.index_of/2` の loop パターンを JoinIR で受理する
|
||||
|
||||
## 現象（最初の FAIL）
|
||||
|
||||
`./tools/smokes/v2/run.sh --profile quick` が `json_lint_vm` で失敗する。
|
||||
|
||||
エラー:
|
||||
|
||||
```
|
||||
[joinir/freeze] Loop lowering failed: JoinIR does not support this pattern, and LoopBuilder has been removed.
|
||||
Function: StringUtils.index_of/2
|
||||
```
|
||||
|
||||
## 対象の Nyash コード（最小形）
|
||||
|
||||
`apps/lib/json_native/utils/string.hako`:
|
||||
|
||||
```nyash
|
||||
index_of(s, ch) {
|
||||
local i = 0
|
||||
loop(i < s.length()) {
|
||||
if s.substring(i, i + 1) == ch { return i }
|
||||
i = i + 1
|
||||
}
|
||||
return -1
|
||||
}
|
||||
```
|
||||
|
||||
特徴:
|
||||
- while ループ（`i < s.length()`）
|
||||
- loop body 内に `if (...) { return i }`
|
||||
- tail に `i = i + 1`
|
||||
- ループ後に `return -1`
|
||||
|
||||
## 問題の構造（なぜ落ちるか）
|
||||
|
||||
- 現状は LoopBuilder が削除済みなので、JoinIR パターンがマッチしない loop はすべて freeze する（フォールバックなし）。
|
||||
- つまり “この loop 形” を JoinIR パターンとして受理できるようにするしかない。
|
||||
|
||||
## 解決方針（構造的）
|
||||
|
||||
### 方針 A（推奨・最小）: 「index_of 形」を Pattern として追加する
|
||||
|
||||
- “箱”として 1つ追加し、1つの質問だけに答える:
|
||||
- 「`index_of` 形の loop を JoinIR に lowering できるか？」
|
||||
- by-name（関数名/Box名）でのディスパッチは禁止。
|
||||
- 形（構造）だけでマッチすること。
|
||||
|
||||
### 方針 B（非推奨）: freeze を回避するための例外ルート
|
||||
|
||||
- LoopBuilder が無い以上、ここで例外 fallback を入れるのは Fail-Fast 原則違反になりやすい。
|
||||
- 例: “Unsupported なら解釈器で実行” のような逃げ道は作らない。
|
||||
|
||||
## 実装タスク（P0）
|
||||
|
||||
### 1) 構造抽出（docs → interface）
|
||||
|
||||
- どの AST/StepTree 形を受理するかを README or doc comment に明記
|
||||
- 必須: loop cond が `<`/`<=` の比較で、rhs が `s.length()` または定数/変数（Phase 251/252 の流れと整合）
|
||||
- 必須: loop 内 if が “then return i” である
|
||||
- 必須: update が `i = i + 1`（Phase 253 で analyzer を緩くしたので、ここは loop パターン側の契約にする）
|
||||
|
||||
### 2) 新しい lowering 箱（案）
|
||||
|
||||
候補配置:
|
||||
- `src/mir/join_ir/lowering/loop_patterns/` 配下に `index_of/` を作り、`lower_box.rs` を置く
|
||||
- 目的: 既存 `loop_with_*` 巨大ファイルに寄せず、責務を分離する（設計優先）
|
||||
|
||||
入出力（案）:
|
||||
- 入力: loop condition AST, loop body AST, `current_static_box_name`, env/JoinValueSpace など（Pattern2 と同等の配線）
|
||||
- 出力: `(JoinModule, JoinFragmentMeta)`（既存パターンと同様）
|
||||
|
||||
### 3) condition lowering の利用
|
||||
|
||||
- `s.substring(i, i+1) == ch` の中で `substring` が必要になる。
|
||||
- CoreMethodId では `StringSubstring` は `allowed_in_init=true` / `allowed_in_condition=false`。
|
||||
- ここは “value expression” として lowering するため、
|
||||
- 既存 `condition_lowerer::lower_value_expression` / `MethodCallLowerer::lower_for_init` のルールに合わせる
|
||||
- 条件全体の bool は `Compare` で生成（JoinIR の `MirLikeInst::Compare`）
|
||||
|
||||
### 4) テストと fixture（仕様固定）
|
||||
|
||||
- unit test:
|
||||
- “index_of 形の loop がマッチする” / “JoinIR が生成される” を固定
|
||||
- v2 smoke fixture:
|
||||
- `apps/tests/phase254_p0_index_of_min.hako`
|
||||
- `tools/smokes/v2/profiles/quick/apps/phase254_p0_index_of_vm.sh`（軽いなら quick へ、重いなら integration）
|
||||
|
||||
## 受け入れ基準
|
||||
|
||||
- `./tools/smokes/v2/run.sh --profile quick` が PASS
|
||||
- by-name 分岐を追加していない（構造のみでマッチ）
|
||||
- unsupported の場合は明確な Err（freeze）を維持しつつ、対象形は通る
|
||||
|
||||
## 進捗（P0/P1 完了）
|
||||
|
||||
### ✅ 完了項目
|
||||
|
||||

|
||||
### ❌ ブロッカー（Phase 255 へ引き継ぎ）
|
||||
|
||||
**現象**: Integration テスト失敗
|
||||
```
|
||||
[ERROR] ❌ [rust-vm] VM error: Invalid value:
|
||||
[rust-vm] use of undefined value ValueId(10)
|
||||

|
||||
last_inst=Some(Compare { dst: ValueId(14), op: Ge, lhs: ValueId(10), rhs: ValueId(13) }))
|
||||
```
|
||||
|
||||
**根本原因**: JoinIR→MIR merge/boundary システムが**複数ループ変数を想定していない**
|
||||
|
||||
- 現状の仕様: Pattern 1-5 は単一ループ変数前提（例: `i` のみ）
|
||||
- Pattern 6 の要求: 3変数ループ（`s`, `ch`, `i`）
|
||||
- 問題: PHI ノードが 1つしか作られない（`s` のみ）、`ch` と `i` が undefined
|
||||
|
||||
**影響範囲**:
|
||||
- `JoinInlineBoundaryBuilder` の `with_loop_var_name()` が単一変数想定
|
||||
- `exit_bindings` が単一 carrier 用に設計
|
||||
- `JoinIRConversionPipeline` が複数 PHI 作成に未対応
|
||||
|
||||
**Phase 254 の受け入れ境界**:
|
||||
- ✅ Pattern 6 が検出される
|
||||
- ✅ JoinIR が正しく生成される（main/loop_step/k_exit 構造）
|
||||
- ✅ substring が BoxCall として init-time に emit される
|
||||
- ❌ 実行（VM/LLVM）で PASS にするのは **Phase 255 の範囲**
|
||||
|
||||
### 次フェーズ（Phase 255）

# Phase 255: Multi-param loop の boundary/PHI/wiring を SSOT 化する
|
||||
|
||||
## 前フェーズ（Phase 254）からの引き継ぎ
|
||||
|
||||
Phase 254 で Pattern 6 (ScanWithInit) の実装が完了したが、integration テストで失敗：
|
||||
|
||||
```
|
||||
[ERROR] ❌ [rust-vm] VM error: Invalid value:
|
||||
[rust-vm] use of undefined value ValueId(10)
|
||||
(fn=StringUtils.index_of/2, last_block=Some(BasicBlockId(4)),
|
||||
last_inst=Some(Compare { dst: ValueId(14), op: Ge, lhs: ValueId(10), rhs: ValueId(13) }))
|
||||
```
|
||||
|
||||
## 根本原因
|
||||
|
||||
**JoinIR→MIR merge/boundary システムが複数ループ変数を想定していない**
|
||||
|
||||
### 現状の仕様（Pattern 1-5）
|
||||
|
||||
- 単一ループ変数前提（例: `i` のみ）
|
||||
- `with_loop_var_name()` が1つの変数名を受け取る
|
||||
- `exit_bindings` が単一 carrier を想定
|
||||
|
||||
### Pattern 6 の要求（3変数ループ）
|
||||
|
||||
```nyash
|
||||
index_of(s, ch) {
|
||||
local i = 0
|
||||
loop(i < s.length()) {
|
||||
if s.substring(i, i + 1) == ch { return i }
|
||||
i = i + 1
|
||||
}
|
||||
return -1
|
||||
}
|
||||
```
|
||||
|
||||
必要な変数:
|
||||
- `s`: haystack（ループ不変）
|
||||
- `ch`: needle（ループ不変）
|
||||
- `i`: loop index（ループ状態）
|
||||
|
||||
### 問題の詳細
|
||||
|
||||
1. **PHI ノード作成の不足**:
|
||||
```rust
|
||||
// 期待: 3つの PHI ノード
|
||||
%4 = phi [%0, entry], [%4, loop] // s
|
||||
%5 = phi [%1, entry], [%5, loop] // ch
|
||||
%6 = phi [%2, entry], [%6, loop] // i
|
||||
|
||||
// 実際: 1つだけ作られる
|
||||
%4 = phi [%0, entry], [%4, loop] // s だけ
|
||||
// %5 と %6 が undefined → 実行時エラー！
|
||||
```
|
||||
|
||||
2. **影響箇所**:
|
||||
- `JoinInlineBoundaryBuilder::with_loop_var_name()` - 単一変数想定
|
||||
- `LoopExitBinding` の使い方 - exit_bindings に複数指定しても PHI が作られない
|
||||
- `JoinIRConversionPipeline` の merge 処理 - 複数 PHI 作成に未対応
|
||||
|
||||
## 解決方針（SSOT 化）
|
||||
|
||||
### 方針: LoopState と Invariants を分けて wiring
|
||||
|
||||
**LoopState（変化する変数）**:
|
||||
- `i`: ループカウンタ
|
||||
- 毎イテレーションで更新される
|
||||
- PHI ノードが必要
|
||||
- exit_binding で final value を取得
|
||||
|
||||
**Invariants（不変な変数）**:
|
||||
- `s`, `ch`: ループ内で参照するが変化しない
|
||||
- PHI ノードは必要だが、すべてのイテレーションで同じ値
|
||||
- `phi [init, init, init, ...]` の形になる
|
||||
|
||||
### 実装戦略
|
||||
|
||||
#### Option A（推奨）: Boundary に invariants フィールド追加
|
||||
|
||||
```rust
|
||||
pub struct JoinInlineBoundary {
|
||||
pub join_inputs: Vec<ValueId>, // 既存（main の params）
|
||||
pub host_inputs: Vec<ValueId>, // 既存（host 側の ValueId）
|
||||
|
||||
// 新規追加
|
||||
pub loop_invariants: Vec<(String, ValueId)>, // (変数名, host ValueId)
|
||||
|
||||
pub exit_bindings: Vec<LoopExitBinding>, // 既存（LoopState 用）
|
||||
pub loop_var_name: Option<String>, // 既存（単一変数用、廃止予定）
|
||||
}
|
||||
```
|
||||
|
||||
**利点**:
|
||||
- 既存の Pattern 1-5 に影響なし
|
||||
- invariants の扱いを明示的に分離
|
||||
- PHI 生成ロジックを追加しやすい
|
||||
|
||||
#### Option B: exit_bindings を拡張
|
||||
|
||||
```rust
|
||||
pub enum CarrierRole {
|
||||
LoopState, // 既存: 変化する変数
|
||||
ConditionOnly, // 既存: 条件のみ
|
||||
LoopInvariant, // 新規: ループ不変
|
||||
}
|
||||
```
|
||||
|
||||
**問題点**:
|
||||
- `CarrierRole::LoopInvariant` を追加しても、現状の merge ロジックが対応していない
|
||||
- exit_bindings は "exit value" を想定しているが、invariants は "同じ値を保持" という意味合いが異なる
|
||||
|
||||
### 推奨: Option A
|
||||
|
||||
- invariants を明示的に分離
|
||||
- merge ロジックに invariants 専用の PHI 生成を追加
|
||||
|
||||
## 実装タスク（P0）
|
||||
|
||||
### Task 1: Boundary 構造拡張
|
||||
|
||||
**ファイル**: `src/mir/join_ir/lowering/inline_boundary.rs`
|
||||
|
||||
1. `JoinInlineBoundary` に `loop_invariants` フィールド追加
|
||||
2. `JoinInlineBoundaryBuilder::with_loop_invariants()` メソッド追加
|
||||
|
||||
### Task 2: PHI 生成ロジック拡張
|
||||
|
||||
**ファイル**: `src/mir/join_ir/lowering/inline_boundary.rs` または merge 関連
|
||||
|
||||
1. `loop_invariants` から PHI ノードを生成
|
||||
2. すべてのブロックで同じ値を持つ PHI として作成
|
||||
3. variable_map に登録
|
||||
|
||||
### Task 3: Pattern 6 の boundary 構築を修正
|
||||
|
||||
**ファイル**: `src/mir/builder/control_flow/joinir/patterns/pattern6_scan_with_init.rs`
|
||||
|
||||
1. `with_loop_invariants()` を使って s, ch を登録
|
||||
2. `exit_bindings` は i のみ（LoopState）
|
||||
|
||||
```rust
|
||||
let boundary = JoinInlineBoundaryBuilder::new()
|
||||
.with_inputs(
|
||||
vec![s_param, ch_param, i_param],
|
||||
vec![s_host, ch_host, i_host],
|
||||
)
|
||||
.with_loop_invariants(vec![
|
||||
(parts.haystack.clone(), s_host),
|
||||
(parts.needle.clone(), ch_host),
|
||||
])
|
||||
.with_exit_bindings(vec![i_exit_binding])
|
||||
.with_loop_var_name(Some(parts.loop_var.clone()))
|
||||
.build();
|
||||
```
|
||||
|
||||
### Task 4: Unit Tests
|
||||
|
||||
**ファイル**: `src/mir/join_ir/lowering/inline_boundary.rs` (tests module)
|
||||
|
||||
1. invariants を含む boundary 作成テスト

//! Pattern 6: Scan with Init (index_of/find/contains form)
|
||||
//!
|
||||
//! Phase 254 P0: Dedicated pattern for scan loops with init-time method calls
|
||||
//!
|
||||
//! ## Pattern Structure
|
||||
//!
|
||||
//! ```nyash
|
||||
//! index_of(s, ch) {
|
||||
//! local i = 0
|
||||
//! loop(i < s.length()) {
|
||||
//! if s.substring(i, i + 1) == ch {
|
||||
//! return i
|
||||
//! }
|
||||
//! i = i + 1
|
||||
//! }
|
||||
//! return -1
|
||||
//! }
|
||||
//! ```
|
||||
//!
|
||||
//! ## Detection Criteria (Structure Only - No Function Names)
|
||||
//!
|
||||
//! 1. Loop condition: `i < x.length()` or `i < len`
|
||||
//! 2. Loop body has if statement with:
|
||||
//! - Condition containing MethodCall (e.g., `substring(i, i+1) == ch`)
|
||||
//! - Then branch: early return (break)
|
||||
//! 3. Loop body has step: `i = i + 1`
|
||||
//! 4. Post-loop: return statement (not-found value)
|
||||
//!
|
||||
//! ## Why Not Pattern 2?
|
||||
//!
|
||||
//! - Pattern 2 expects break condition without init-time MethodCall
|
||||
//! - This pattern needs MethodCall in condition (substring)
|
||||
//! - MethodCall allowed_in_condition() = false, but allowed_in_init() = true
|
||||
//! - Need to hoist MethodCall to init phase

//! Phase 254 P1: Pattern 6 (ScanWithInit) Minimal Lowerer
|
||||
//!
|
||||
//! Target: apps/tests/phase254_p0_index_of_min.hako
|
||||
//!
|
||||
//! Code:
|
||||
//! ```nyash
|
||||
//! static box StringUtils {
|
||||
//! index_of(s, ch) {
|
||||
//! local i = 0
|
||||
//! loop(i < s.length()) {
|
||||
//! if s.substring(i, i + 1) == ch {
|
||||
//! return i
|
||||
//! }
|
||||
//! i = i + 1
|
||||
//! }
|
||||
//! return -1
|
||||
//! }
|
||||
//! }
|
||||
//! ```
|
||||
//!
|
||||
//! Expected JoinIR:
|
||||
//! ```text
|
||||
//! fn main(s, ch, i):
|
||||
//! result = loop_step(s, ch, i)
|
||||
//! // Post-loop early return will be inserted by MirBuilder
|
||||
//!
|
||||
//! fn loop_step(s, ch, i):
|
||||
//! // 1. Check exit condition: i >= s.length()
|
||||
//! len = StringBox.length(s)
|
||||
//! exit_cond = (i >= len)
|
||||
//! Jump(k_exit, [-1], cond=exit_cond) // Not found case
|
||||
//!
|
||||
//! // 2. Calculate i_plus_1 for substring
|
||||
//! i_plus_1 = i + 1
|
||||
//!
|
||||
//! // 3. Hoist MethodCall(substring) to init-time BoxCall
|
||||
//! cur = StringBox.substring(s, i, i_plus_1)
|
||||
//!
|
||||
//! // 4. Check match condition
|
||||
//! match = (cur == ch)
|
||||
//! Jump(k_exit, [i], cond=match) // Found case
|

||||
//! ```
|
||||
//!
|
||||
//! ## Design Notes
|
||||
//!
|
||||
//! This is a MINIMAL P0 implementation targeting index_of pattern specifically.
|
||||
//! Key features:
|
||||
//! - substring is emitted as BoxCall (init-time, not condition whitelist)
|
||||
//! - Two Jump instructions to k_exit (not found: -1, found: i)
|
||||
//! - Step must be 1 (P0 restriction)
|
||||
//! - not_found_return_lit must be -1 (P0 restriction)

//! Phase 252: User-Defined Method Policy Box
|
||||
//!
|
||||
//! This box provides a Single Source of Truth (SSOT) for determining whether
|
||||
//! user-defined static box methods are allowed in JoinIR contexts.
|
||||
//!
|
||||
//! ## Design Philosophy
|
||||
//!
|
||||
//! **Box-First Design**: UserMethodPolicy is a single-responsibility box that
|
||||
//! answers one question: "Can this static box method be safely lowered to JoinIR?"
|
||||
//!
|
||||
//! **Metadata-Driven**: Uses a policy table to determine allowed methods.
|
||||
//! NO method name hardcoding in lowering logic - all decisions made here.
|
||||
//!
|
||||
//! **Fail-Fast**: If a method is not in the policy table, immediately returns false.
|
||||
//! No silent fallbacks or guessing.
|
||||
//!
|
||||
//! **Future Extension**: This SSOT can be moved to .hako annotations or nyash.toml
|
||||
//! in the future without breaking lowering logic.
|
||||
//!
|
||||
//! ## Supported Static Boxes
|
||||
//!
|
||||
//! - **StringUtils**: String utility functions (trim, character checks, etc.)
|
||||
//!
|
||||
//! ## Example Usage
|
||||
//!
|
||||
//! ```ignore
|
||||
//! // Check if StringUtils.is_whitespace is allowed in condition
|
||||
//! if UserMethodPolicy::allowed_in_condition("StringUtils", "is_whitespace") {
|
||||
//! // Lower this.is_whitespace(...) to JoinIR
|
||||
//! }
|
||||
//! ```
