feat(joinir): Phase 188.3 - Pattern6 (NestedLoopMinimal) 選択ロジック実装
## Phase 188.3 進捗: Phase 2 完了 (6/13 tasks) ### 実装完了 ✅ **Phase 1: Fixture作成** - apps/tests/phase1883_nested_minimal.hako 追加 - Add/Compare のみ（乗算なし） - 期待 exit code: 9 (3×3 nested loops) - 既存 lowering で fallback 動作確認 **Phase 2: 選択ロジック (SSOT)** - LoopPatternContext に step_tree_max_loop_depth フィールド追加 - choose_pattern_kind() に Pattern6 選択ロジック実装: 1. Cheap check (has_inner_loop) 2. StepTree 構築 (max_loop_depth 取得) 3. AST validation (is_pattern6_lowerable) - pattern6_nested_minimal.rs モジュール作成 (stub) - LOOP_PATTERNS に Pattern6 entry 追加 - **検証**: Pattern6 が正しく選択される ✅ ### 設計原則 (確認済み) 1. **Fail-Fast**: Pattern6 選択後は Ok(None) で逃げない 2. **outer 変数 write-back 検出 → validation false** (Phase 188.4+) 3. **最小実装**: inner local だけ、Pattern1 モデル二重化 4. **cfg! 依存なし**: production で動作 ### 検証結果 ``` [choose_pattern_kind] has_inner_loop=true [choose_pattern_kind] max_loop_depth=2 [choose_pattern_kind] is_pattern6_lowerable=true ✅ Pattern6 SELECTED! ``` Stub からの期待エラー: ``` [ERROR] ❌ [Pattern6] Nested loop lowering not yet implemented ``` ### 次: Phase 3 (Lowering 実装 - 推定4時間) 残りタスク: - Phase 3-1: AST 抽出ヘルパー - Phase 3-2: Validation ヘルパー - Phase 3-3: Continuation 生成 (outer_step, inner_step, k_inner_exit) - Phase 3-4: fixture が exit=9 を返すことを検証 ### 変更ファイル **新規**: - apps/tests/phase1883_nested_minimal.hako - src/mir/builder/control_flow/joinir/patterns/pattern6_nested_minimal.rs - docs/development/current/main/phases/phase-188.{1,2,3}/README.md **変更**: - src/mir/builder/control_flow/joinir/routing.rs (Pattern6 選択) - src/mir/builder/control_flow/joinir/patterns/router.rs (Context 拡張) - src/mir/builder/control_flow/joinir/patterns/mod.rs (module 宣言) 🎯 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

# Self Current Task — Now (main)
|
||||
|
||||
## Current Focus: Phase 29y（post self-host, docs-first）
|
||||
## Current Focus: Phase 188.3 (Nested Loop Lowering)
|
||||
|
||||
Phase 285 の "weak + hidden root + LLVM one-pass（検出/設定含む）" は完全完了（P4 Post-Completion 含む）。次は post self-host の Phase 29y（MIR lifecycle vocab freeze相談）を docs-first で進める。
|
||||
**2025-12-27: Phase 188.2 完了** ✅

|
||||
- quick 154/154 PASS、integration selfhost FAIL=0 維持
|
||||
- 次: `docs/development/current/main/phases/phase-188.3/README.md`（depth=2 を JoinIR lowering で通す / 変数はread-only capture→write-backは次フェーズ）
|
||||
|
||||
**2025-12-27: Phase S0.1 完了** ✅
|
||||
- integration selfhost を「落ちない状態」に収束（FAIL=0）
|
||||
- canary テスト opt-in 化（SMOKES_ENABLE_SELFHOST=1、9本）
|
||||
- baseline テスト条件付き SKIP（該当ログの時だけ、unknown は FAIL 維持）
|
||||
- quick 154/154 PASS 維持、Fail-Fast 原則遵守
|
||||
- SSOT: [selfhost-integration-limitations.md](investigations/selfhost-integration-limitations.md)
|
||||
|
||||
**2025-12-27: Phase S0 Selfhost Integration 安定化（実ログベース）完了** ✅
|
||||
- **実ログ採取完了**: 5本のスクリプト直叩き + 全体ログで事実確定（推定排除）
|
||||
- **確認済みエラーパターン**（実ログベース）:
|
||||
- Pattern 1: Loop lowering failed / StepTree lowering returned None（JoinIR loop pattern gap）
|
||||
- Pattern 2: cap_missing/NestedLoop（JoinIR caps gap）
|
||||
- Pattern 3: strict mode panic（NYASH_JOINIR_STRICT=1 削除で対応）
|
||||
- Pattern 4: Argument list too long（OS limitation）
|
||||
- **条件付き SKIP 実装**: selfhost_minimal.sh, phase150, mir_min_vm, canary 4本（該当ログの時だけ、それ以外はFAIL）
|
||||
- **進捗**: 12 FAIL → 10 FAIL（selfhost_minimal, mir_min_vm が PASS に）
|
||||
- **quick smoke**: 154/154 PASS 維持 ✅
|
||||
- **SSOT**: [selfhost-integration-limitations.md](investigations/selfhost-integration-limitations.md)
|
||||
- **未確認**: String+Integer 型エラー（実ログで未検出、追加しない）
|
||||
|
||||
**2025-12-27: Phase 29y.1（pilot plumbing）完了** ✅

# Selfhost Integration Test Limitations
|
||||
|
||||
**Date**: 2025-12-27 (Updated with actual log findings)
|
||||
**Context**: Phase S0 selfhost integration stabilization
|
||||
**Investigator**: Claude Code
|
||||
**Status**: Actual Log-Based Analysis (No Speculation)
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
Integration selfhost tests show 12 FAILs out of 33 tests. This document is based on **actual test execution logs** collected on 2025-12-27.
|
||||
|
||||
**Key Principle**: This analysis uses ONLY confirmed error patterns from real logs. No speculation or estimation.
|
||||
|
||||
**Log Collection**:
|
||||
- Full integration selfhost run: `/tmp/integration_selfhost_full.log`
|
||||
- Individual script logs: `/tmp/selfhost_minimal.log`, `/tmp/phase150.log`, etc.
|
||||
|
||||
**Resolution Strategy**: Conditional SKIP (該当ログが出た時だけ、それ以外はFAIL)
|
||||
|
||||
---
|
||||
|
||||
## 実ログ確認済みエラーパターン
|
||||
|
||||
### Pattern 1: JoinIR Loop Lowering Failure
|
||||
|
||||
**Error Tag**: `[joinir/freeze] Loop lowering failed`
|
||||
|
||||
**Full Error Message**:
|
||||
```
|
||||
[ERROR] ❌ MIR compilation error: [joinir/freeze] Loop lowering failed: JoinIR does not support this pattern, and LoopBuilder has been removed.
|
||||
Function: BundleResolver.resolve/4
|
||||
Hint: This loop pattern is not supported. All loops must use JoinIR lowering.
|
||||
```
|
||||
|
||||
**Confirmed in**:
|
||||
- `selfhost_minimal.sh` (BundleResolver.resolve/4)
|
||||
- `selfhost_mir_min_vm.sh` (MirVmMin._str_to_int)
|
||||
|
||||
**Root Cause**: Phase 188 JoinIR loop patterns don't support all loop constructs. Legacy LoopBuilder was removed in Phase 187.
|
||||
|
||||
**Category**: JoinIR loop pattern gap
|
||||
|
||||
---
|
||||
|
||||
### Pattern 2: JoinIR Caps Gap (NestedLoop)
|
||||
|
||||
**Error Tag**: `cap_missing/NestedLoop`
|
||||
|
||||
**Full Error Message**:
|
||||
```
|
||||
[joinir/control_tree] missing cap: NestedLoop in BundleResolver.resolve/4
|
||||
[ERROR] ❌ MIR compilation error: [joinir/control_tree/cap_missing/NestedLoop] NestedLoop detected in 'BundleResolver.resolve/4' (step_tree_sig=967e04269f051967) Hint: refactor to avoid nested loops (not supported yet) or run without HAKO_JOINIR_STRICT=1
|
||||
```
|
||||
|
||||
**Confirmed in**:
|
||||
- `selfhost_minimal.sh` (visible in full integration log)
|
||||
|
||||
**Root Cause**: JoinIR control_tree lacks NestedLoop capability
|
||||
|
||||
**Category**: JoinIR caps gap
|
||||
|
||||
**Note**: This error appears BEFORE Pattern 1 in selfhost_minimal.sh, suggesting the script encounters Pattern 2 first.
|
||||
|
||||
---
|
||||
|
||||
### Pattern 3: Strict-Only Canary (Pattern Not Matched)
|
||||
|
||||
**Error Tag**: `strict mode: pattern not matched`
|
||||
|
||||
**Full Error Message**:
|
||||
```
|
||||
thread 'main' panicked at src/mir/builder/if_form.rs:328:29:
|
||||
[joinir/if] strict mode: pattern not matched for IfSelectTest.test/1 (if_form.rs)
|
||||
```
|
||||
|
||||
**Confirmed in**:
|
||||
- `selfhost_phase150_depth1_smoke.sh` (testing joinir_if_select_simple.hako)
|
||||
- Runs with `NYASH_JOINIR_STRICT=1`
|
||||
|
||||
**Root Cause**: if_form.rs strict mode validation catches unmatched pattern
|
||||
|
||||
**Category**: strict-only canary
|
||||
|
||||
**Design Intent**: Strict mode is intentionally strict to catch edge cases. Not meant for baseline stability.
|
||||
|
||||
---
|
||||
|
||||
### Pattern 4: Selfhost Child Spawn Limitation
|
||||
|
||||
**Error Tag**: `Argument list too long (os error 7)`
|
||||
|
||||
**Full Error Message**:
|
||||
```
|
||||
[selfhost-child] spawn failed: Argument list too long (os error 7)
|
||||
```
|
||||
|
||||
**Confirmed in**:
|
||||
- `selfhost_minimal.sh`
|
||||
|
||||
**Root Cause**: OS kernel limitation (ARG_MAX) for subprocess argument list length
|
||||
|
||||
**Category**: OS limitation
|
||||
|
||||
**Note**: This error appears FIRST in selfhost_minimal.sh execution, before any JoinIR errors.

|
||||
|
||||
**Total FAILs**: 12 (from full integration run on 2025-12-27)
|
||||
**Total PASSes**: 21
|
||||
**Total Tests**: 33
|
||||
|
||||
---
|
||||
|
||||
## 未確認パターン（実ログで確認されなかった）
|
||||
|
||||
### String+Integer Type Error (NOT confirmed)
|
||||
|
||||
**Previous Speculation** (from Task agent):
|
||||
- "6-8 tests fail due to String + Integer auto-conversion not supported"
|
||||
- Example: `print("" + integer_value)`
|
||||
|
||||
**Actual Log Finding**: ❌ **NOT confirmed in any collected logs**
|
||||
|
||||
**Conclusion**: Either:
|
||||
1. This pattern doesn't occur in current selfhost tests, OR
|
||||
2. Tests were fixed to use `.toString()`, OR
|
||||
3. The speculation was incorrect
|
||||
|
||||
**Action**: Do NOT add SKIP for this pattern. Only add if confirmed in actual logs.
|
||||
|
||||
---
|
||||
|
||||
## Resolution Strategy (Phase S0 & S0.1)
|
||||
|
||||
### Phase S0.1 Update: Canary Tests Opt-In
|
||||
|
||||
**Canary Tests**: Opt-in via `SMOKES_ENABLE_SELFHOST=1` (Phase S0.1) - not required for baseline integration
|
||||
|
||||
**Affected Tests** (9 canary tests):
|
||||
- `phase2047/*_canary_vm.sh` (5 tests)
|
||||
- `phase2051/*_canary_vm.sh` (4 tests)
|
||||
|
||||
**Rationale**: These are advanced/experimental selfhost tests. Baseline integration stability doesn't require them to pass.
|
||||
|
||||
### Principle: 条件付き SKIP（Conditional SKIP Only)
|
||||
|
||||
**Approach**: SKIP only when specific error pattern appears in logs, otherwise FAIL
|
||||
|
||||
**Implementation Example** (Pattern 1):
|
||||
```bash
|
||||
# Phase S0: JoinIR loop lowering failure - conditional SKIP
|
||||
# SSOT: docs/development/current/main/investigations/selfhost-integration-limitations.md
|
||||
|
||||
if [ "$exit_code" -ne 0 ]; then
|
||||
if echo "$output" | grep -q "Loop lowering failed"; then
|
||||
log_skip "selfhost_*: Pattern 1 (JoinIR loop pattern gap - Phase 188 limitation)"
|
||||
exit 0
|
||||
fi
|
||||
# それ以外のエラーは FAIL のまま（回帰を隠さない）
|
||||
log_error "selfhost_*: FAIL (unknown error, not Pattern 1)"
|
||||
echo "$output"
|
||||
exit 1
|
||||
fi
|
||||
```
|
||||
|
||||
### Critical Constraints
|
||||
|
||||
- ✅ **quick 154/154 PASS 維持** (一切触らない)
|
||||
- ✅ **Phase 29y 凍結** (新しい lifecycle/RC 実装拡張はしない)
|
||||
- ✅ **Fail-Fast** (silent fallback 禁止)
|
||||
- ✅ **最小差分** (SKIP マーカー追加のみ)
|
||||
|
||||
### Prohibited Actions
|
||||
|
||||
- ❌ 無条件 SKIP (unconditional SKIP)
|
||||
- ❌ 新規 env var 追加
|
||||
- ❌ 直読み（std::env::var）増殖
|
||||
- ❌ quick を重くする変更
|
||||
- ❌ silent fallback
|
||||

|
||||
|
||||
## Root Cause Analysis
|
||||
|
||||
### Why Pattern 1 & 2 (JoinIR Gaps)?
|
||||
|
||||
**Phase 187**: Removed LoopBuilder (legacy loop implementation)
|
||||
**Phase 188**: Implemented 3 basic JoinIR loop patterns (80% coverage goal)
|
||||
|
||||
**Result**: Some complex loop patterns not yet supported:
|
||||
- Multiple continue statements in single loop
|
||||
- Nested loops (NestedLoop capability)
|
||||
- Complex control flow combinations
|
||||
|
||||
**Design Trade-off**: Phase 188 prioritized common patterns to ship quickly. Complex patterns deferred.
|
||||
|
||||
**Fix Scope**: Requires Phase 188 continuation (JoinIR pattern expansion) - NOT in scope for Phase S0
|
||||
|
||||
### Why Pattern 3 (Strict Mode)?
|
||||
|
||||
**Design Intent**: `NYASH_JOINIR_STRICT=1` is a canary mode to catch unmatched patterns early
|
||||
|
||||
**Purpose**: Development/debugging, not baseline stability
|
||||
|
||||
**Resolution**: Either remove NYASH_JOINIR_STRICT=1 from baseline tests, OR conditional SKIP for strict mode errors
|
||||
|
||||
### Why Pattern 4 (Argument List Too Long)?
|
||||
|
||||
**Root Cause**: Linux kernel ARG_MAX limitation (typically ~2MB on modern systems)
|
||||
|
||||
**Context**: selfhost_build.sh passes large amounts of data via command-line arguments
|
||||
|
||||
**Fix Scope**: Requires architectural change (use files/stdin instead of argv) - NOT in scope for Phase S0
|
||||
|
||||
---
|
||||
|
||||
## Future Work (Out of Scope for Phase S0)
|
||||
|
||||
### Phase 188 Continuation (JoinIR Pattern Expansion)
|
||||
|
||||
**Patterns Needed**:
|
||||
- NestedLoop capability (Pattern 2)
|
||||
- Complex control flow with multiple continue (Pattern 1)
|
||||
- Infinite loops with early exits
|
||||
|
||||
**Effort**: ~2-5 days per pattern (based on Phase 188 experience)
|
||||
|
||||
**Priority**: Medium (selfhost compiler .hako files need these patterns)
|
||||
|
||||
### Selfhost Build Architecture
|
||||
|
||||
**Issue**: Pattern 4 (Argument list too long)
|
||||
|
||||
**Solution**: Replace argv-based data passing with file-based or stdin-based approach
|
||||
|
||||
**Effort**: ~1-2 days
|
||||
|
||||
**Priority**: Low (affects only selfhost_minimal.sh currently)

## Conclusion
|
||||
|
||||
**Fact-Based Analysis**: All findings confirmed by actual test execution logs on 2025-12-27
|
||||
|
||||
**12 FAILs** categorized into 4 confirmed patterns:
|
||||
1. **Pattern 1**: JoinIR loop lowering failure (2+ tests)
|
||||
2. **Pattern 2**: JoinIR caps gap - NestedLoop (1 test)
|
||||
3. **Pattern 3**: strict mode panic (1 test)
|
||||
4. **Pattern 4**: Argument list too long (1 test, appears with Pattern 1)
|
||||
|
||||
**Canary Tests**: 7 tests fail with rc=1 but no error detail in logs
|
||||
|
||||
**String+Integer speculation**: ❌ NOT confirmed in actual logs
|
||||
|
||||
**Next Step**: Implement conditional SKIP for confirmed patterns only (Task 2)
|
||||
|
||||
**Quick Profile Safety**: 154/154 PASS maintained ✅

# Phase 188.1: cap_missing/NestedLoop 解除（strict gate unblock）
|
||||
|
||||
**Date**: 2025-12-27
|
||||
**Goal**: `cap_missing/NestedLoop` を解除して、`selfhost_minimal` を integration で PASS させる（Fail-Fastを崩さない）
|
||||
**Status**: ✅ Capability gate unblock 完了 / ❌ Pattern 6（検出・lowering）は Phase 188.2+ に deferred
|
||||
|
||||
---
|
||||
|
||||
## ⚠️ Implementation Reality (Phase 188.1 Scope)
|
||||
|
||||
### What Phase 188.1 actually did
|
||||
|
||||
- ✅ **StepTree capability gate**: `StepCapability::NestedLoop` を strict allowlist に追加して、`cap_missing/NestedLoop` を解除した
|
||||
- ✅ **Integration導線**: `selfhost_minimal` の SKIP を撤去しても integration selfhost が FAIL=0 になることを確認した
|
||||
|
||||
### What Phase 188.1 did NOT do
|
||||
|
||||
- ❌ **Nested loop の自動検出（LoopFormベース）**は未実装
|
||||
`loop_pattern_detection::extract_features()` は `max_loop_depth=1` / `has_inner_loops=false` の固定値（TODO）で、Pattern 6 の分岐は到達しない
|
||||
- ❌ **Pattern 6 lowering** は未実装
|
||||
`src/mir/join_ir/lowering/loop_patterns/nested_minimal.rs` はインフラ（stub）で、現状 `None` を返す
|
||||
|
||||
### Why LoopForm-based nesting detection is impossible (current architecture)
|
||||
|
||||
Nesting depth は **StepTree（AST側）**にはあるが、**LoopForm（MIR側）**には存在しない。
|
||||
|
||||
- ✅ StepTree: `StepTreeFeatures.max_loop_depth`（AST → StepTree 変換時に計算）
|
||||
- ❌ LoopForm: `LoopForm = LoopShape` は CFG ブロック参照だけを持ち、親子/深さ情報が無い
|
||||
|
||||
従って、ネスト深さの検査や Pattern 6 の自動検出を **LoopFormレイヤーだけで完結させることはできない**。
|
||||
次の実装は Phase 188.2 で「StepTree側を使うか / LoopRegion（親子構造）を実装するか」を docs-first で決める。
|
||||

## Pattern 6 Specification: NestedLoop Minimal
|
||||
|
||||
**Note**: このセクションは「目標仕様（design）」であり、Phase 188.1 では gate unblock のみ完了。実装は Phase 188.2+。
|
||||
|
||||
### Supported Forms (ONLY)
|
||||
|
||||
**Pattern**: Outer Pattern 1 + Inner Pattern 1
|
||||
|
||||
```nyash
|
||||
// Outer loop: Pattern 1 (simple while, no break/continue)
|
||||
loop(outer_cond) {
|
||||
// ... outer loop body before inner ...
|
||||
|
||||
// Inner loop: Pattern 1 ONLY (simple while, no break/continue)
|
||||
loop(inner_cond) {
|
||||
// ... inner loop body ...
|
||||
}
|
||||
|
||||
// ... outer loop body after inner ...
|
||||
}
|
||||
```
|
||||
|
||||
**Requirements**:
|
||||
- **Outer loop**: Pattern 1 (Simple While) - no break/continue
|
||||
- **Inner loop**: Pattern 1 (Simple While) - no break/continue
|
||||
- **Nesting depth**: EXACTLY 1 level (`max_loop_depth == 2`)
|
||||
- **No control flow**: No break/continue in either loop
|
||||
- **Sequential execution**: Inner loop completes before outer continues
|
||||
|
||||
### Unsupported Forms (Explicit Error)
|
||||
|
||||
**Rejected with明示エラー** (no silent fallback):
|
||||
|
||||
1. **Deeper nesting** (`max_loop_depth > 2`):
|
||||
```
|
||||
[joinir/nested_loop/depth_exceeded] max_loop_depth=3 exceeds limit (max=2)
|
||||
Hint: Refactor to avoid 3+ level nesting, or split into separate functions
|
||||
```
|
||||
|
||||
2. **Inner loop with break/continue**:
|
||||
```
|
||||
[joinir/nested_loop/inner_control_flow] Inner loop has break/continue (not supported)
|
||||
Hint: Only simple while loops (Pattern 1) supported as inner loops
|
||||
```
|
||||
|
||||
3. **Outer loop with break/continue**:
|
||||
```
|
||||
[joinir/nested_loop/outer_control_flow] Outer loop has break/continue (not supported)
|
||||
Hint: Only simple while loops (Pattern 1) supported as outer loops
|
||||
```
|
||||
|
||||
4. **Multiple inner loops** (siblings):
|
||||
```
|
||||
[joinir/nested_loop/multiple_inner] Multiple inner loops detected (not supported)
|
||||
Hint: Only one inner loop per outer loop supported
|
||||
```
|
||||
|
||||

|
||||
|
||||
## JoinIR Lowering Strategy
|
||||
|
||||
### Example Input (Nyash)
|
||||
|
||||
```nyash
|
||||
static box Main {
|
||||
main() {
|
||||
local outer_i = 0
|
||||
loop(outer_i < 3) {
|
||||
local inner_j = 0
|
||||
loop(inner_j < 2) {
|
||||
print(inner_j)
|
||||
inner_j = inner_j + 1
|
||||
}
|
||||
outer_i = outer_i + 1
|
||||
}
|
||||
return 0
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Expected Output (JoinIR Pseudocode)
|
||||
|
||||
```text
|
||||
fn main():
|
||||
Call(outer_step, [0, k_main_exit])
|
||||
|
||||
fn outer_step(outer_i, k_outer_exit):
|
||||
// Exit condition check
|
||||
exit_cond = !(outer_i < 3)
|
||||
Jump(k_outer_exit, [], cond=exit_cond) // Early exit if condition false
|
||||
|
||||
// Initialize inner loop variables
|
||||
inner_j = 0
|
||||
|
||||
// Inner loop step function (nested inside outer_step)
|
||||
fn inner_step(inner_j, k_inner_exit):
|
||||
exit_cond = !(inner_j < 2)
|
||||
Jump(k_inner_exit, [], cond=exit_cond)
|
||||
|
||||
print(inner_j)
|
||||
inner_j_next = inner_j + 1
|
||||
Call(inner_step, [inner_j_next, k_inner_exit]) // Tail recursion
|
||||
|
||||
// k_inner_exit continuation (resume outer loop body after inner completes)
|
||||
fn k_inner_exit():
|
||||
outer_i_next = outer_i + 1
|
||||
Call(outer_step, [outer_i_next, k_outer_exit]) // Outer tail recursion
|
||||
|
||||
// Entry: call inner loop
|
||||
Call(inner_step, [inner_j, k_inner_exit])
|
||||
|
||||
fn k_main_exit():
|
||||
return 0
|
||||
```
|
||||
|
||||
**Key Points**:
|
||||
- **Nested functions**: Inner step function is defined inside outer step function
|
||||
- **Continuation wiring**: `k_inner_exit` resumes outer loop body after inner completes
|
||||
- **Carrier isolation**: Outer carriers (`outer_i`) and inner carriers (`inner_j`) are separate
|
||||
- **Same pattern as Pattern 1**: Both loops use tail-recursive step function pattern
|
||||
|

|

## ⚠️ Implementation Reality (Phase 188.1 Scope)
|
||||
|
||||
### What Was Actually Implemented
|
||||
|
||||
**Phase 188.1 delivered**:
|
||||
1. ✅ **StepTree capability gate**: `StepCapability::NestedLoop` added to allowlist
|
||||
2. ✅ **Pattern 6 enum**: `Pattern6NestedLoopMinimal` classification added
|
||||
3. ✅ **Lowering stub**: `nested_minimal.rs` module created (infrastructure only)
|
||||
4. ✅ **Test pass**: selfhost_minimal conditional SKIP removed, 154/154 PASS maintained
|
||||
|
||||
**Phase 188.1 did NOT implement**:
|
||||
- ❌ **Automatic nesting detection from LoopForm**: LoopForm (= LoopShape) has NO nesting information
|
||||
- ❌ **Pattern 6 lowering logic**: `lower_nested_loop_minimal_to_joinir()` returns `None` (stub)
|
||||
- ❌ **LoopRegion integration**: LoopRegion parent/child structure exists but is NOT instantiated
|
||||
|
||||
### Why Automatic Detection Is NOT Possible (Current Architecture)
|
||||
|
||||
**LoopForm Limitation**:
|
||||
```rust
|
||||
// src/mir/loop_form.rs
|
||||
pub type LoopForm = crate::mir::control_form::LoopShape;
|
||||
|
||||
// LoopShape structure (src/mir/control_form.rs):
|
||||
pub struct LoopShape {
|
||||
pub preheader: BasicBlockId,
|
||||
pub header: BasicBlockId,
|
||||
pub body: Vec<BasicBlockId>,
|
||||
pub latch: BasicBlockId,
|
||||
pub exit_blocks: Vec<BasicBlockId>,
|
||||
// ❌ NO parent field
|
||||
// ❌ NO children field
|
||||
// ❌ NO depth field
|
||||
}
|
||||
```
|
||||
|
||||
**Nesting information exists ONLY in StepTree** (AST level):
|
||||
```rust
|
||||
// src/mir/control_tree/step_tree.rs (line 17-25)
|
||||
pub struct StepTreeFeatures {
|
||||
pub max_loop_depth: u32, // ← Detected during AST → StepTree conversion
|
||||
// ...
|
||||
}
|
||||
```
|
||||
- ✅ AST parsing time: Nesting depth calculated
|
||||
- ❌ MIR lowering time: LoopForm has NO access to this information
|
||||
|
||||
**LoopRegion infrastructure exists but is NOT integrated**:
|
||||
```rust
|
||||
// src/mir/control_form.rs (line 40-62) - Phase 32 definition
|
||||
pub struct LoopRegion {
|
||||
pub parent: Option<LoopId>, // ← Structure defined
|
||||
pub children: Vec<LoopId>, // ← But NOT instantiated anywhere
|
||||
}
|
||||
```
|
||||
|
||||
### Where Nesting Depth Checking MUST Happen
|
||||
|
||||
**✅ Possible locations**:
|
||||
1. **StepTree level** (before LoopForm creation):
|
||||
- Use `StepTreeFeatures.max_loop_depth` during control flow analysis
|
||||
- Reject `max_loop_depth > 2` at StepTree → LoopForm conversion time
|
||||
|
||||
2. **LoopRegion level** (if integrated in Phase 188.2+):
|
||||
- Use `LoopRegion.parent` to compute actual nesting depth
|
||||
- Build LoopRegion tree and check depth constraints
|
||||
|
||||
**❌ Impossible location**:
|
||||
- **LoopForm level**: No nesting information available (by design)
|
||||
|
||||
### Phase 188.2 Design Decision Required
|
||||
|
||||
**Choice A: StepTreeFeatures Integration**
|
||||
- Pass `StepTreeFeatures` (AST-level) to JoinIR lowering
|
||||
- Use `max_loop_depth` from StepTree for Pattern 6 detection
|
||||
- Pro: Nesting info already exists
|
||||
- Con: AST-level info may not match MIR structure (optimizations)
|
||||
|
||||
**Choice B: LoopRegion Integration**
|
||||
- Instantiate `LoopRegion` with parent/child relationships
|
||||
- Compute nesting depth from MIR control flow graph
|
||||
- Pro: MIR-level truth (accurate after optimizations)
|
||||
- Con: Requires implementing LoopRegion builder (Phase 32 infrastructure not yet wired)
|
||||
|
||||
**Decision timeline**: Phase 188.2 planning session (docs-first approach)
|
||||

## Implementation Files
|
||||
|
||||
### New Files Created
|
||||
|
||||
1. **`src/mir/join_ir/lowering/loop_patterns/nested_minimal.rs`**
|
||||
- Phase 188.1: インフラ（stub）。現状 `lower_nested_loop_minimal_to_joinir()` は `None` を返す
|
||||
|
||||
### Modified Files
|
||||
|
||||
1. **`src/mir/loop_pattern_detection/mod.rs`** (~15 lines)
|
||||
- Add `Pattern6NestedLoopMinimal` enum variant
|
||||
- Add `max_loop_depth`, `has_inner_loops` to `LoopFeatures`
|
||||
- Update `extract_features()`, `classify()`
|
||||
|
||||
2. **`src/mir/join_ir/lowering/loop_patterns/mod.rs`** (~2 lines)
|
||||
- Export `nested_minimal` module
|
||||
|
||||
3. **`src/mir/join_ir/lowering/loop_pattern_router.rs`** (~10 lines)
|
||||
- Add Pattern 6 routing case
|
||||
- Add explicit error for `max_loop_depth > 2`
|
||||
|
||||
4. **`src/mir/builder/control_flow/joinir/control_tree_capability_guard.rs`** (~1 line)
|
||||
- Add `StepCapability::NestedLoop` to allowlist
|
||||
|
||||
5. **`tools/smokes/v2/profiles/integration/selfhost/selfhost_minimal.sh`** (~6 lines removed)
|
||||
- Remove conditional SKIP for `cap_missing/NestedLoop`
|
||||
|
||||

|
||||
|
||||
## Integration Points
|
||||
|
||||
### Detection Pipeline
|
||||
|
||||
1. **AST → StepTree** (`step_tree.rs` lines 461-463):
|
||||
```rust
|
||||
if features.max_loop_depth > 1 {
|
||||
facts.add_capability(StepCapability::NestedLoop);
|
||||
}
|
||||
```
|
||||
|
||||
2. **StepTree → Contract** (automatic capability contract check)
|
||||
|
||||
3. **Contract → Guard** (`control_tree_capability_guard.rs` line 44):
|
||||
```rust
|
||||
StepCapability::NestedLoop, // Phase 188.1: Now in allowlist
|
||||
```
|
||||
|
||||
4. **LoopForm → Pattern Detection** (`loop_pattern_detection::classify()`):
|
||||
```rust
|
||||
// Phase 188.1: Pattern 6 enum defined, but detection logic is STUB
|
||||
// Currently always returns max_loop_depth = 1 (default)
|
||||
// because LoopForm has NO nesting information.
|
||||
//
|
||||
// TODO (Phase 188.2): Integrate StepTreeFeatures or LoopRegion
|
||||
// to enable actual nesting detection.
|
||||
if features.max_loop_depth == 2
|
||||
&& features.has_inner_loops
|
||||
&& !features.has_break
|
||||
&& !features.has_continue
|
||||
{
|
||||
return LoopPatternKind::Pattern6NestedLoopMinimal; // Never reached (stub)
|
||||
}
|
||||
```
|
||||
|
||||
5. **Pattern → Lowering** (`loop_pattern_router.rs`):
|
||||
```rust
|
||||
LoopPatternKind::Pattern6NestedLoopMinimal => {
|
||||
super::loop_patterns::lower_nested_loop_minimal_to_joinir(loop_form, lowerer)
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Success Criteria
|
||||
|
||||
### Functional Requirements
|
||||
|
||||
- ✅ `selfhost_minimal.sh`: Remove conditional SKIP, test PASS (or explicit error)
|
||||
- ✅ `integration --filter "selfhost_"`: FAIL=0 maintained
|
||||
- ✅ `quick`: 154/154 PASS unchanged
|
||||
|
||||
### Quality Requirements
|
||||
|
||||
- ✅ Explicit errors for unsupported forms (no silent `Ok(None)`)
|
||||
- ✅ Phase 286 Fail-Fast principle maintained (no silent fallback)
|
||||
- ✅ Minimal diff (~180 lines total)
|
||||
|
||||
---
|
||||
|
||||
## Out of Scope (Future Work)
|
||||
|
||||
**Deferred to Phase 188.2+**:
|
||||
- Pattern 6 の実装（ネスト検出のSSOT決定 + lowering 実装）
|
||||
- break/continue in nested loops (Pattern 2/4 inner/outer combinations)
|
||||
- Multiple inner loops (siblings)
|
||||
- 2+ level nesting (3+ loop depth)
|
||||
- Nested loops with PHI (Pattern 3 inner/outer combinations)
|
||||
- Shared carriers between outer/inner loops
|
||||
|
||||
**Rationale**: Phase 188.1 is minimal PoC to unblock selfhost_minimal. Complex patterns deferred to avoid scope creep.

## End of Phase 188.1 Documentation
|
||||

||||
**Status**: Infrastructure complete, detection logic deferred to Phase 188.2

# Phase 188.2: StepTree nesting depth SSOT (Option A) — strict Fail-Fast
|
||||
|
||||
**Date**: 2025-12-27
|
||||
**Status**: ✅ Option A implemented / ❌ Pattern 6 lowering deferred (Phase 188.3+)
|
||||
**Goal**: `StepTreeFeatures.max_loop_depth` を SSOT として、strict mode で depth > 2 を明示エラーにする
|
||||
|
||||
---
|
||||
|
||||
## ✅ Decision: Option A Adopted (2025-12-27)
|
||||
|
||||
**Chosen Approach**: StepTreeFeatures Integration
|
||||
|
||||
**What Phase 188.2 Implements**:
|
||||
- Use `StepTree.features.max_loop_depth` as SSOT for nesting depth
|
||||
- Add explicit error for `max_loop_depth > 2` in strict mode (capability_guard.rs)
|
||||
- Update NestedLoop capability hint to reflect current support
|
||||
|
||||
**Implementation Location**:
|
||||
- `src/mir/builder/control_flow/joinir/control_tree_capability_guard.rs` (lines 32-76)
|
||||
|
||||
**Status**: Option A depth checking implemented, Option B deferred
|
||||
|
||||
---
|
||||
|
||||
## What Phase 188.2 delivered
|
||||
|
||||
- ✅ strict mode の depth 制約を SSOT 化（`max_loop_depth > 2` は明示エラー）
|
||||
- ✅ NestedLoop capability hint を現実に合わせて更新（1-levelは許可、2+ level は depth_exceeded）
|
||||
- ✅ unit tests 更新（depth=2 PASS / depth=3 FAIL）
|
||||
- ✅ quick/integration は不変（回帰なし）
|
||||
|
||||
### Verification (reference)
|
||||
|
||||
- quick: `./tools/smokes/v2/run.sh --profile quick`
|
||||
- integration selfhost: `./tools/smokes/v2/run.sh --profile integration --filter "selfhost_"`
|
||||
|
||||
---
|
||||
|
||||
## Background
|
||||
|
||||
Phase 188.1 delivered infrastructure (capability allowlist, enum, stub module), but **detection and lowering are NOT implemented** due to architectural limitations.
|
||||
|
||||
**See**: `docs/development/current/main/phases/phase-188.1/README.md` § Implementation Reality
|
||||
|
||||
---
|
||||
|
||||
## Design Decision Required (Choose A or B)
|
||||
|
||||
### Option A: StepTreeFeatures Integration
|
||||
|
||||
**Approach**:
|
||||
- Pass `StepTreeFeatures` from StepTree to LoopForm creation
|
||||
- Store `max_loop_depth` in LoopForm (add field) or pass via context
|
||||
- Use AST-level nesting depth for Pattern 6 detection
|
||||
|
||||
**Pros**:
|
||||
- Nesting info already exists in StepTree
|
||||
- No new detection logic required
|
||||
- Fast implementation
|
||||
|
||||
**Cons**:
|
||||
- AST-level info may diverge from MIR structure (after optimizations)
|
||||
- Adding fields to LoopForm breaks separation of concerns
|
||||
|
||||
**Estimated Effort**: 1-2 days
|
||||
|
||||
---
|
||||
|
||||
### Option B: LoopRegion Integration
|
||||
|
||||
**Approach**:
|
||||
- Implement LoopRegion builder (instantiate parent/child structure)
|
||||
- Build LoopRegion tree from MIR control flow graph
|
||||
- Compute nesting depth from LoopRegion.parent traversal
|
||||
- Replace LoopForm with LoopRegion in lowering pipeline
|
||||
|
||||
**Pros**:
|
||||
- MIR-level truth (accurate after optimizations)
|
||||
- Leverages Phase 32 infrastructure
|
||||
- Clean separation (LoopRegion is designed for nesting)
|
||||
|
||||
**Cons**:
|
||||
- Requires implementing LoopRegion builder (non-trivial)
|
||||
- Larger architectural change
|
||||
- May affect other loop analysis code
|
||||
|
||||
**Estimated Effort**: 1-2 weeks
|
||||
|
||||
---
|
||||
|
||||
## Planning Session Agenda
|
||||
|
||||
**Step 1: Docs-First Design Review**
|
||||
- Review Option A vs B trade-offs
|
||||
- Consider impact on selfhost_minimal requirements
|
||||
- Decide on approach based on scope/timeline
|
||||
|
||||
**Step 2: Detailed Implementation Plan**
|
||||
- Write step-by-step implementation guide
|
||||
- Identify critical files
|
||||
- Estimate effort per task
|
||||
|
||||
**Step 3: Implementation**
|
||||
- Execute chosen approach
|
||||
- Test with selfhost_minimal
|
||||
- Verify 154/154 PASS maintained
|
||||
|
||||
---
|
||||
|
||||
## Out of Scope (Phase 188.2)
|
||||
|
||||
Still deferred to Phase 188.3+:
|
||||
- Break/continue in nested loops (Pattern 2/4 combinations)
|
||||
- Multiple inner loops (siblings)
|
||||
- 2+ level nesting (depth > 2) の lowering（Phase 188.2 は strict Fail-Fast のみ）
|
||||
|
||||
**Rationale**: Phase 188.2 focuses on 1-level nesting detection only (minimal scope).

||||

## End of Phase 188.2 Planning Stub
|
||||
|

**Status**: Option A is complete; remaining work is Phase 188.3+
|

# Phase 188.3: Nested loop lowering (1-level) — make Pattern 6 real
|
||||
|
||||
**Date**: TBD
|
||||
**Status**: Planning (docs-first)
|
||||
**Prereq**: Phase 188.2 Option A is complete (StepTree depth SSOT + strict Fail-Fast)
|
||||
|
||||
---
|
||||
|
||||
## Goal
|
||||
|
||||
`max_loop_depth == 2`（1-level nested loop）を **JoinIR lowering で実際に通す**。
|
||||
|
||||
- 既知の事実: `LoopForm (=LoopShape)` にはネスト情報が無いので、**LoopFormベースの Pattern6 検出/ルーティングでは実装できない**
|
||||
- 実装は **StepTree（AST側）**を SSOT として扱う（Phase 188.2 Option A を継続）
|
||||
|
||||
---
|
||||
|
||||
## Scope (minimal)
|
||||
|
||||
対応するのは “NestedLoop Minimal” の 1形だけに限定する。
|
||||
|
||||
- depth: `max_loop_depth == 2` のみ
|
||||
- inner loop: Pattern1相当（break/continue 無し）
|
||||
- outer loop: Pattern1相当（break/continue 無し）を優先
|
||||
- それ以外:
|
||||
- strict mode: 明示エラー（Phase 188.2 の depth check とは別タグで良い）
|
||||
- non-strict mode: 既存の fallback 経路に任せる（ただし silent fallback を増やさない）
|
||||
|
||||
---
|
||||
|
||||
## SSOT (what to rely on)
|
||||
|
||||
- nesting depth SSOT: `StepTreeFeatures.max_loop_depth`
|
||||
- depth > 2: strict mode で `control_tree/nested_loop/depth_exceeded`（Phase 188.2）
|
||||
|
||||
---
|
||||
|
||||
## Scope & Variable Model (SSOT)
|
||||
|
||||
Nyash の変数スコープ方針に合わせて、nested loop lowering でも以下を SSOT として固定する。
|
||||
|
||||
### Visibility (read)
|
||||
|
||||
- inner loop から outer の binding は参照できる（lexical scope: “1つ上は見える”）
|
||||
- ただし JoinIR lowering では「見える」を **明示的な引数/継続で表現**する（暗黙キャプチャを増やさない）
|
||||
|
||||
### Mutation (write-back)
|
||||
|
||||
Phase 188.3 では段階的に進める：
|
||||
|
||||
- **P188.3 (minimal)**: outer 変数の **read-only capture** を許す（inner から outer を読む）
|
||||
- **P188.4+ (generalize)**: outer 変数の **write-back** を対応する（inner で outer に代入した値を `k_inner_exit(...)` で戻す）
|
||||
|
||||
この分離により、PHI/exit binding の複雑さを Phase 188.3 に持ち込まずに済む。
|
||||
|
||||
---
|
||||
|
||||
## Lowering sketch (how it should look)
|
||||
|
||||
Nested loop は JoinIR の「tail recursion + continuation」を再帰的に合成して表現する。
|
||||
|
||||
- outer: `outer_step(state..., k_outer_exit)`
|
||||
- inner: `inner_step(state..., k_inner_exit)`
|
||||
- inner が終わったら `k_inner_exit(...)` で outer の“残り”へ戻る
|
||||
|
||||
この `k_inner_exit` がスコープ境界として働くので、将来の write-back もここに集約できる。
|
||||
|
||||
---
|
||||
|
||||
## Deliverables
|
||||
|
||||
1. **Fixture + integration smoke（exit code SSOT）**
|
||||
- 1-level nested loop を最小で再現する `.hako` を追加
|
||||
- integration で実行し、exit code で判定（stdout比較はしない）
|
||||
|
||||
2. **StepTree-based lowering implementation**
|
||||
- StepTree を辿って、inner loop を outer loop の中で正しく lowering できるようにする
|
||||
- 入口は “StepTree→JoinIR” のどこか（LoopFormベースの router は使わない）
|
||||
|
||||
3. **Docs update**
|
||||
- Phase 188.1 の “Pattern6 specification” が design であることは維持
|
||||
- Phase 188.3 で “実装済み/未実装の境界” を明確に書く
|
||||
|
||||
---
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
- `./tools/smokes/v2/run.sh --profile quick` が常にグリーン維持
|
||||
- integration selfhost が FAIL=0 を維持
|
||||
- 追加した nested loop fixture が PASS（JoinIR lowering が使われたことをログ/タグで確認可能）
|
||||
|
||||
---
|
||||
|
||||
## Next (schedule)
|
||||
|
||||
- **Phase 188.3**: depth=2 の最小形を “確実に通す” + PoC fixture を smoke 固定
|
||||
- **Phase 188.4+**: write-back（outer carrier reconnection）と “再帰 lowering の一般化（depthを増やしても壊れない）” を docs-first で設計してから実装
|
||||
|
||||
---
|
||||
|
||||
## Out of Scope
|
||||
|
||||
- nested loop + break/continue の一般対応
|
||||
- LoopRegion を使った MIR-level nesting SSOT（Option B）

//! Pattern 6: Nested Loop Minimal Lowering (Phase 188.1)
|
||||
//!
|
||||
//! Target: 1-level nested simple while loops
|
||||
//! Example: `loop(i < 3) { loop(j < 2) { ... } }`
|
||||
//!
|
||||
//! # Transformation
|
||||
//!
|
||||
//! ```text
|
||||
//! // Outer loop step function
|
||||
//! fn outer_step(outer_i, k_outer_exit):
|
||||
//! exit_cond = !(outer_i < 3)
|
||||
//! Jump(k_outer_exit, [], cond=exit_cond) // exit if condition false
|
||||
//!
|
||||
//! // Initialize inner loop variables
|
||||
//! inner_j = 0
|
||||
//!
|
||||
//! // Inner loop step function (nested)
|
||||
//! fn inner_step(inner_j, k_inner_exit):
|
||||
//! exit_cond = !(inner_j < 2)
|
||||
//! Jump(k_inner_exit, [], cond=exit_cond)
|
||||
//!
|
||||
//! print(inner_j)
|
||||
//! inner_j_next = inner_j + 1
|
||||
//! Call(inner_step, [inner_j_next, k_inner_exit]) // tail recursion
|
||||
//!
|
||||
//! // k_inner_exit continuation (resume outer loop)
|
||||
//! fn k_inner_exit():
|
||||
//! outer_i_next = outer_i + 1
|
||||
//! Call(outer_step, [outer_i_next, k_outer_exit]) // outer tail recursion
|
||||
//!
|
||||
//! // Entry: call inner loop
|
||||
//! Call(inner_step, [inner_j, k_inner_exit])
|
||||
//!
|
||||
//! // Main entry
|
||||
//! Call(outer_step, [0, k_main_exit])
|
||||
//! ```
|
||||
//!
|
||||
//! # Key Design Points
|
||||
//!
|
||||
//! - Outer step function contains inner step function (nested structure)
|
||||
//! - `k_inner_exit` resumes outer loop body after inner completes
|
||||
//! - Outer/inner carriers are isolated (no shared carriers)
|
||||
//! - Both loops use same tail-recursive pattern as Pattern 1
|
||||
//!
|
||||
//! # Supported Forms (Phase 188.1 Scope)
|
||||
//!
|
||||
//! - **Outer loop**: Pattern 1 (simple while, no break/continue)
|
||||
//! - **Inner loop**: Pattern 1 (simple while, no break/continue)
|
||||
//! - **Nesting depth**: EXACTLY 1 level (`max_loop_depth == 2`)
|
||||
//! - **No control flow**: No break/continue in either loop
|
||||
//! - **Sequential execution**: Inner loop completes before outer continues
|
||||
//!
|
||||
//! # Unsupported Forms (Explicit Error)
|
||||
//!
|
||||
//! - Deeper nesting (2+ levels): `max_loop_depth > 2`
|
||||
//! - Inner loop with break/continue
|
||||
//! - Outer loop with break/continue
|
||||
//! - Multiple inner loops (siblings)
|
||||
//!
|
||||
//! # Reference
|
||||
//!
|
||||
//! See `docs/development/current/main/phases/phase-188.1/README.md` for complete specification.

// TODO: Implement Pattern 6 lowering (Phase 188.1 Task 4)
|

//
|
||||
// Step 1: Detect Outer + Inner Loops
|
||||
// ===================================
|
||||
// Validate loop_form is outer loop, find inner loop in body
|
||||
//
|
||||
// ```rust
|
||||
// let inner_loop = find_inner_loop_in_body(loop_form)?;
|
||||
// validate_nested_structure(loop_form, inner_loop)?;
|
||||
// ```
|
||||
//
|
||||
// Step 2: Extract Outer Loop Variables
|
||||
// =====================================
|
||||
// From outer header PHI: %2 = phi [%1, bb1], [%6, bb_outer_latch]
|
||||
//
|
||||
// ```rust
|
||||
// let outer_carriers = extract_carriers_from_header_phi(loop_form)?;
|
||||
// ```
|
||||
//
|
||||
// Step 3: Extract Inner Loop Variables
|
||||
// =====================================
|
||||
// From inner header PHI: %10 = phi [%9, bb_inner_preheader], [%14, bb_inner_latch]
|
||||
//
|
||||
// ```rust
|
||||
// let inner_carriers = extract_carriers_from_header_phi(inner_loop)?;
|
||||
// ```
|
||||
//
|
||||
// Step 4: Create Outer Step Function
|
||||
// ===================================
|
||||
// Signature: fn outer_step(outer_i: ValueId, k_outer_exit: JoinContId)
|
||||
//
|
||||
// ```rust
|
||||
// let outer_step_id = lowerer.allocate_join_func_id();
|
||||
// let k_outer_exit_id = lowerer.allocate_join_func_id();
|

// // 1. Exit condition check: exit_cond = !(outer_i < 3)

// // 3. Initialize inner loop: inner_j = 0
|
||||
// // 4. Call(inner_step, [inner_j, k_inner_exit])
|
||||
// ```
|
||||
//
|
||||
// Step 5: Create Inner Step Function (Nested)
|
||||
// ============================================
|
||||
// Signature: fn inner_step(inner_j: ValueId, k_inner_exit: JoinContId)
|
||||
//
|
||||
// ```rust
|
||||
// let inner_step_id = lowerer.allocate_join_func_id();
|
||||
//
|
||||
// // Inner step function body:
|
||||
// // 1. Exit condition check: exit_cond = !(inner_j < 2)
|
||||
// // 2. Jump(k_inner_exit, [], cond=exit_cond)
|
||||
// // 3. Translate inner body instructions
|
||||
// // 4. Update inner carrier: inner_j_next = inner_j + 1
|
||||
// // 5. Tail call: Call(inner_step, [inner_j_next, k_inner_exit])
|
||||
// ```
|
||||
//
|
||||
// Step 6: Create k_inner_exit Continuation
|
||||
// =========================================
|
||||
// Resumes outer loop after inner completes
|
||||
//
|
||||
// ```rust
|
||||
// let k_inner_exit_func = JoinFunction {
|
||||
// id: k_inner_exit_id,
|
||||
// name: "k_inner_exit".to_string(),
|
||||
// params: vec![], // No values passed from inner to outer
|
||||
// body: vec![
|
||||
// // Update outer carrier: outer_i_next = outer_i + 1
|
||||
// // Tail call to outer: Call(outer_step, [outer_i_next, k_outer_exit])
|
||||
// ],
|
||||
// exit_cont: Some(k_outer_exit_id),
|
||||
// };
|
||||
// lowerer.register_join_function(k_inner_exit_func);
|
||||
// ```
|
||||
//
|
||||
// Step 7: Wire Continuations
|
||||
// ===========================
|
||||
// Connect inner/outer exits to appropriate continuations
|
||||
//
|
||||
// ```rust
|
||||
// // Inner step exit → k_inner_exit
|
||||
// // Outer step exit → k_outer_exit (parent continuation)
|
||||
// ```
|
||||
|
||||
// For now, return None (stub implementation)

// Actual implementation will be added incrementally

None
