From c3a26e705ef984f976e1b1d8c0e2db34df50d1c1 Mon Sep 17 00:00:00 2001 From: nyash-codex Date: Fri, 12 Dec 2025 05:23:18 +0900 Subject: [PATCH] feat(joinir): Phase 47-A-IMPL - P3 Normalized infrastructure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement Pattern3 (if-sum) Normalized infrastructure, extending existing P2 StepSchedule and ShapeGuard systems. Key changes: 1. StepSchedule generalization (P2 → P2/P3): - Renamed: pattern2_step_schedule.rs → step_schedule.rs - Extended StepKind enum with P3 variants: - IfCond (if condition in body) - ThenUpdates (carrier updates in then branch) - ElseUpdates (carrier updates in else branch) - Added pattern3_if_sum_schedule() function - Added unit test: test_pattern3_if_sum_schedule() - Updated module references (mod.rs, loop_with_break_minimal.rs) 2. ShapeGuard extension: - Added Pattern3IfSumMinimal variant to NormalizedDevShape - Added is_pattern3_if_sum_minimal() detector (placeholder) - Updated shape detector table - Extended capability_for_shape() mapping 3. Bridge integration: - bridge.rs: Added P3 shape handling in normalize_for_shape() - normalized.rs: Added P3 roundtrip match (uses P2 temporarily) 4. P2/P3 separation: - loop_with_break_minimal.rs: Added panic for P3 steps in P2 lowering - Clear boundary enforcement (P2 lowerer rejects P3 steps) 5. Documentation: - CURRENT_TASK.md: Phase 47-A-IMPL status - phase47-norm-p3-design.md: Implementation status section Benefits: - Reuses 90% of P2 infrastructure (ConditionEnv, CarrierInfo, ExitLine) - Clean P2/P3 separation via StepKind - Pure additive changes (no P2 behavioral changes) - Ready for Phase 47-A-LOWERING (full P3 Normalized implementation) Tests: 938/938 PASS (+1 from step_schedule unit test) - All existing P1/P2 tests pass (no regressions) - P3 test uses Structured path temporarily (proper lowering in next phase) Next phase: Implement full P3 Normalized→MIR(direct) lowering --- CURRENT_TASK.md | 7 +++ .../current/main/phase47-norm-p3-design.md | 21 ++++++++ .../lowering/loop_with_break_minimal.rs | 6 ++- src/mir/join_ir/lowering/mod.rs | 2 +- ...ern2_step_schedule.rs => step_schedule.rs} | 53 +++++++++++++++---- src/mir/join_ir/normalized.rs | 5 ++ src/mir/join_ir/normalized/shape_guard.rs | 21 ++++++++ src/mir/join_ir_vm_bridge/bridge.rs | 4 ++ 8 files changed, 107 insertions(+), 12 deletions(-) rename src/mir/join_ir/lowering/{pattern2_step_schedule.rs => step_schedule.rs} (77%) diff --git a/CURRENT_TASK.md b/CURRENT_TASK.md index a4c67f7c..e9707790 100644 --- a/CURRENT_TASK.md +++ b/CURRENT_TASK.md @@ -87,6 +87,13 @@ - JsonParser P2 ライン（_skip_whitespace/_atoi/_parse_number）全て canonical Normalized 化完了。 - P3/P4 Normalized 対応は NORM-P3/NORM-P4 フェーズで実施（今回スコープ外）。 - 937/937 tests PASS。 +- **Phase 47-A-IMPL（実装中 2025-12-12）**: + - StepScheduleBox 汎用化: pattern2_step_schedule.rs → step_schedule.rs リネーム + - P3 StepKind 追加: IfCond, ThenUpdates, ElseUpdates（P2 lowering との分離完了） + - ShapeGuard: Pattern3IfSumMinimal 検出追加（placeholder stub実装） + - Normalized bridge: P3 shape handling 追加（P2 normalization 使用） + - 938/938 tests PASS（regression なし） + - 次ステップ: Phase 47-A-LOWERING で full P3 Normalized lowering 実装 - **Phase 45-NORM-MODE（実装済み✅ 2025-12-12）**: - JoinIR モード一本化: バラバラだったフラグ/feature を `JoinIrMode` enum に集約（StructuredOnly / NormalizedDev / NormalizedCanonical）。 - `current_joinir_mode()` でモード取得、bridge/runner で `normalized_dev_enabled()` → mode pattern matching に移行。 diff --git a/docs/development/current/main/phase47-norm-p3-design.md b/docs/development/current/main/phase47-norm-p3-design.md index 10490c2c..6bff217c 100644 --- a/docs/development/current/main/phase47-norm-p3-design.md +++ b/docs/development/current/main/phase47-norm-p3-design.md @@ -155,6 +155,27 @@ loop(i < arr.length()) { Complex P3 patterns from selfhost compiler (deferred to later phase). +## Implementation Status + +**Phase 47-A-PREP** (✅ Complete, commit 42ecd7a7): +- Fixture added: `pattern3_if_sum_minimal` in `normalized/fixtures.rs` +- Test stub added: `test_normalized_pattern3_if_sum_minimal_runner_dev_switch_matches_structured` +- Basic infrastructure for P3 development mode testing + +**Phase 47-A-IMPL** (✅ Complete, 2025-12-12): +- ✅ StepSchedule renamed and extended: `pattern2_step_schedule.rs` → `step_schedule.rs` +- ✅ P3 StepKind added: `IfCond`, `ThenUpdates`, `ElseUpdates` +- ✅ Pattern2 lowering separation: P3 steps panic in P2 lowering (clean boundary) +- ✅ ShapeGuard: `Pattern3IfSumMinimal` detection added (placeholder stub) +- ✅ Normalized bridge: P3 shape handling in `normalize_for_shape()` and roundtrip +- ✅ 938/938 tests PASS (no regressions) +- ⏳ TODO: Full P3 Normalized lowering (Phase 47-A-LOWERING) + +**Next Phase** (Phase 47-A-LOWERING): +- Implement `lower_pattern3_if_sum_minimal()` fully +- Generate Normalized JpInst for P3 structure (If branching, conditional updates) +- Test VM output comparison (Normalized vs Structured) + ## Implementation Strategy ### Phase 47-A: Minimal sum_count (dev-only) diff --git a/src/mir/join_ir/lowering/loop_with_break_minimal.rs b/src/mir/join_ir/lowering/loop_with_break_minimal.rs index 3b47bb4f..19128e57 100644 --- a/src/mir/join_ir/lowering/loop_with_break_minimal.rs +++ b/src/mir/join_ir/lowering/loop_with_break_minimal.rs @@ -70,7 +70,7 @@ use crate::mir::join_ir::lowering::join_value_space::JoinValueSpace;
