From d2972c1437fe34a56e3a784cd775e0bbb6423df4 Mon Sep 17 00:00:00 2001 From: nyash-codex Date: Tue, 16 Dec 2025 21:37:07 +0900 Subject: [PATCH] =?UTF-8?q?feat(joinir):=20Phase=2092=E5=AE=8C=E4=BA=86=20?= =?UTF-8?q?-=20ConditionalStep=20+=20body-local=E5=A4=89=E6=95=B0=E3=82=B5?= =?UTF-8?q?=E3=83=9D=E3=83=BC=E3=83=88?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Phase 92全体の成果 **Phase 92 P0-P2**: ConditionalStep JoinIR生成とbody-local変数サポート - ConditionalStep（条件付きキャリア更新）のJoinIR生成実装 - Body-local変数（ch等）の条件式での参照サポート - 変数解決優先度: ConditionEnv → LoopBodyLocalEnv **Phase 92 P3**: BodyLocalPolicyBox + 安全ガード - BodyLocalPolicyDecision実装（Accept/Reject判定） - BodyLocalSlot + DualValueRewriter（JoinIR/MIR二重書き込み） - Fail-Fast契約（Cannot promote LoopBodyLocal検出） **Phase 92 P4**: E2E固定＋回帰最小化 (本コミット) - Unit test 3本追加（body-local変数解決検証） - Integration smoke追加（phase92_pattern2_baseline.sh、2ケースPASS） - P4-E2E-PLAN.md、P4-COMPLETION.md作成 ## 主要な実装 ### ConditionalStep（条件付きキャリア更新） - `conditional_step_emitter.rs`: JoinIR Select命令生成 - `loop_with_break_minimal.rs`: ConditionalStep検出と統合 - `loop_with_continue_minimal.rs`: Pattern4対応 ### Body-local変数サポート - `condition_lowerer.rs`: body-local変数解決機能 - `lower_condition_to_joinir`: body_local_env パラメータ追加 - 変数解決優先度実装（ConditionEnv優先） - Unit test 3本追加: 変数解決/優先度/エラー - `header_break_lowering.rs`: break条件でbody-local変数参照 - 7ファイルで後方互換ラッパー（lower_condition_to_joinir_no_body_locals） ### Body-local Policy & Safety - `body_local_policy.rs`: BodyLocalPolicyDecision（Accept/Reject） - `body_local_slot.rs`: JoinIR/MIR二重書き込み - `dual_value_rewriter.rs`: ValueId書き換えヘルパー ## テスト体制 ### Unit Tests (+3) - `test_body_local_variable_resolution`: body-local変数解決 - `test_variable_resolution_priority`: 変数解決優先度（ConditionEnv優先） - `test_undefined_variable_error`: 未定義変数エラー - 全7テストPASS（cargo test --release condition_lowerer::tests） ### Integration Smoke (+1) - `phase92_pattern2_baseline.sh`: - Case A: loop_min_while.hako (Pattern2 baseline) - Case B: phase92_conditional_step_minimal.hako (条件付きインクリメント) - 両ケースPASS、integration profileで発見可能 ### 退行確認 - ✅ 既存Pattern2Breakテスト正常（退行なし） - ✅ Phase 135 smoke正常（MIR検証PASS） ## アーキテクチャ設計 ### 変数解決メカニズム ```rust // Priority 1: ConditionEnv (loop params, captured) if let Some(value_id) = env.get(name) { return Ok(value_id); } // Priority 2: LoopBodyLocalEnv (body-local like `ch`) if let Some(body_env) = body_local_env { if let Some(value_id) = body_env.get(name) { return Ok(value_id); } } ``` ### Fail-Fast契約 - Delta equality check (conditional_step_emitter.rs) - Variable resolution error messages (ConditionEnv) - Body-local promotion rejection (BodyLocalPolicyDecision::Reject) ## ドキュメント - `P4-E2E-PLAN.md`: 3レベルテスト戦略（Level 1-2完了、Level 3延期） - `P4-COMPLETION.md`: Phase 92完了報告 - `README.md`: Phase 92全体のまとめ ## 将来の拡張（Phase 92スコープ外） - Body-local promotionシステム拡張 - P5bパターン認識の汎化（flagベース条件サポート） - 完全なP5b E2Eテスト（body-local promotion実装後） 🎯 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- .../phase92_conditional_step_minimal.hako | 42 ++ .../main/phases/phase-92/P4-COMPLETION.md | 161 +++++++ .../main/phases/phase-92/P4-E2E-PLAN.md | 93 ++++ .../current/main/phases/phase-92/README.md | 9 + .../control_flow/joinir/loop_context.rs | 12 +- .../joinir/merge/block_allocator.rs | 9 +- .../joinir/merge/carrier_init_builder.rs | 28 +- .../joinir/merge/exit_line/meta_collector.rs | 78 ++- .../joinir/merge/exit_line/mod.rs | 12 +- .../joinir/merge/exit_line/reconnector.rs | 111 +++-- .../joinir/merge/exit_phi_builder.rs | 33 +- .../joinir/merge/expr_result_resolver.rs | 42 +- .../joinir/merge/instruction_rewriter.rs | 139 ++++-- .../joinir/merge/loop_header_phi_builder.rs | 95 ++-- .../builder/control_flow/joinir/merge/mod.rs | 453 +++++++++++------- .../joinir/merge/value_collector.rs | 24 +- .../control_flow/joinir/parity_checker.rs | 23 +- .../joinir/patterns/body_local_policy.rs | 92 ++++ .../joinir/patterns/common_init.rs | 5 +- .../joinir/patterns/condition_env_builder.rs | 50 +- .../control_flow/joinir/patterns/mod.rs | 1 + .../joinir/patterns/pattern2_with_break.rs | 250 +++++----- .../joinir/patterns/pattern3_with_if_phi.rs | 31 +- .../joinir/patterns/trim_loop_lowering.rs | 197 +++++--- .../builder/control_flow/joinir/routing.rs | 72 +-- src/mir/builder/control_flow/joinir/trace.rs | 45 ++ .../lowering/carrier_update_emitter.rs | 4 +- src/mir/join_ir/lowering/common.rs | 2 + .../lowering/common/body_local_slot.rs | 314 ++++++++++++ .../common/conditional_step_emitter.rs | 4 +- .../lowering/common/dual_value_rewriter.rs | 118 +++++ src/mir/join_ir/lowering/condition_lowerer.rs | 179 ++++++- .../join_ir/lowering/condition_to_joinir.rs | 8 +- src/mir/join_ir/lowering/debug_output_box.rs | 24 +- src/mir/join_ir/lowering/expr_lowerer.rs | 6 +- .../join_ir/lowering/loop_body_local_init.rs | 87 ++-- .../lowering/loop_with_break_minimal.rs | 369 +++++++------- .../header_break_lowering.rs | 21 +- .../lowering/loop_with_break_minimal/tests.rs | 23 +- .../lowering/loop_with_continue_minimal.rs | 203 +++++--- src/mir/join_ir/normalized/fixtures.rs | 23 +- .../test_pattern5b_escape_minimal.hako | 9 +- .../apps/phase92_pattern2_baseline.sh | 94 ++++ 43 files changed, 2615 insertions(+), 980 deletions(-) create mode 100644 apps/tests/phase92_conditional_step_minimal.hako create mode 100644 docs/development/current/main/phases/phase-92/P4-COMPLETION.md create mode 100644 docs/development/current/main/phases/phase-92/P4-E2E-PLAN.md create mode 100644 src/mir/builder/control_flow/joinir/patterns/body_local_policy.rs create mode 100644 src/mir/join_ir/lowering/common/body_local_slot.rs create mode 100644 src/mir/join_ir/lowering/common/dual_value_rewriter.rs create mode 100644 tools/smokes/v2/profiles/integration/apps/phase92_pattern2_baseline.sh diff --git a/apps/tests/phase92_conditional_step_minimal.hako b/apps/tests/phase92_conditional_step_minimal.hako new file mode 100644 index 00000000..a361d20f --- /dev/null +++ b/apps/tests/phase92_conditional_step_minimal.hako @@ -0,0 +1,42 @@ +// Phase 92 P4-1: Minimal E2E test for ConditionalStep support +// +// This test verifies that ConditionalStep (conditional carrier increment) +// works correctly in Pattern2 with break conditions. +// +// Pattern: Simple conditional increment based on loop variable +// Expected output: 3 +// +// Why 3? +// -

Phase 92 P3: ReadOnlyBodyLocalSlot Box +//! +//! Purpose: support the minimal case where a loop condition/break condition +//! references a loop-body-local variable (e.g., `ch`) that is recomputed every +//! iteration and is read-only (no assignment). +//! +//! This box is intentionally narrow and fail-fast: +//! - Supports exactly 1 body-local variable used in conditions. +//! - Requires a top-level `local = ` before the break-guard `if`. +//! - Forbids any assignment to that variable (including in nested blocks). +//! +//! NOTE: This box does NOT lower the init expression itself. +//! Lowering is handled by `LoopBodyLocalInitLowerer` (Phase 186). +//!
