## Phase 146 P0: ANF Routing SSOT Unified **Goal**: Unify ANF routing in `lower_expr_with_scope()` L54-84, remove legacy lowering **Changes**: - expr_lowerer_box.rs: Added scope check (PureOnly → skip ANF, WithImpure → try ANF) - post_if_post_k.rs: Removed legacy inline lowering (L271-285), added `lower_condition_legacy()` helper - contract.rs: Already had `CondLoweringFailed` out-of-scope reason **Test Results**: ✅ Phase 146 P0 smoke (exit 7), 0 regressions ## Phase 146 P1: Compare Operator Support **Goal**: Enable ANF for condition expressions with Compare operators **Changes**: - joinir_dev.rs: Added `anf_allow_pure_enabled()` (HAKO_ANF_ALLOW_PURE=1) - expr_lowerer_box.rs: PureOnly scope ANF support (L56-66) - execute_box.rs: Compare operator support (+122 lines) - `execute_compare_hoist()`, `execute_compare_recursive()`, `ast_compare_to_joinir()` - Extended `normalize_and_lower()` for Compare **Test Results**: ✅ Phase 146 P1 smoke (exit 7 with flags), 0 regressions ## Phase 147 P0: Recursive Comparison ANF **Goal**: Extend recursive ANF to Compare operators **Changes**: - contract.rs: Added `AnfParentKind::Compare` variant - plan_box.rs: Compare case in BinaryOp routing (L68-79, L134-139) - Distinguishes Compare vs arithmetic BinaryOp **Benefits**: Enables recursive ANF for comparisons - `s.length() == 3` → `t = s.length(); if (t == 3)` ✅ - `s1.length() < s2.length()` → `t1 = s1.length(); t2 = s2.length(); if (t1 < t2)` ✅ ## Implementation Summary **Files Modified** (9 files, +253 lines, -25 lines = +228 net): 1. src/config/env/joinir_dev.rs (+28 lines) 2. src/mir/control_tree/normalized_shadow/anf/contract.rs (+2 lines) 3. src/mir/control_tree/normalized_shadow/anf/execute_box.rs (+122 lines) 4. src/mir/control_tree/normalized_shadow/anf/plan_box.rs (+18 lines) 5. src/mir/control_tree/normalized_shadow/common/expr_lowerer_box.rs (+18 lines, -0 lines) 6. src/mir/control_tree/normalized_shadow/post_if_post_k.rs (+44 lines, -25 lines) 7.

# CURRENT_TASK (moved)
|
||
|
||
Status: SSOT
|
||
Scope: Repo root の旧リンク互換。現行の入口は `docs/development/current/main/10-Now.md`。
|
||
|
||
- Now: `docs/development/current/main/10-Now.md`
|
||
- Backlog: `docs/development/current/main/30-Backlog.md`

## Handoff (current)
|
||
|
||
### 状況(SSOT)
|
||
|
||
- 現行の入口: `docs/development/current/main/10-Now.md`
|
||
- 次の候補: `docs/development/current/main/30-Backlog.md`
|
||
|
||
### 直近の道筋(JoinIR / Normalized)
|
||
|
||
### 設計方針メモ(SSOT候補)
|
||
|
||
- ExprLowererBox(式SSOT)
|
||
- 役割: `AST(expr)` → `(prelude: Vec<Inst>, value: ValueId)`(ANF含む)
|
||
- pure/impure/whitelist/strict の契約を集約(入口SSOT)
|
||
- ConditionLowererBox(条件→分岐SSOT)
|
||
- 役割: `AST(cond)` → `BranchPlan`(短絡なら分岐語彙で組む)
|
||
- 評価順は ExprLowererBox に委譲(ANFで順序固定)
|
||
- `&&/||` は制御として扱い、式で無理しない
|
||
- ControlLowererBox(制御SSOT)
|
||
- 役割: `StepNode/ControlTree` → JoinIR(継続 + env)
|
||
- `if/loop` はここ、条件の中身は ConditionLowererBox に委譲
|
||
|
||
- Phase 139: if-only `post_k` の return lowering を `ReturnValueLowererBox` に統一(DONE)

||
- `docs/development/current/main/phases/phase-139/README.md`

||
- `docs/development/current/main/phases/phase-142-loopstmt/README.md`
|
||
- Phase 142-loopstmt P1: LLVM EXE smoke(同 fixture)を追加(DONE)
|
||
- `docs/development/current/main/phases/phase-142-loopstmt/README.md`
|
||
- Phase 141 P2+: Call/MethodCall(effects + typing)を分離して段階投入
|
||
- Historical context: `docs/development/current/main/investigations/joinir-generalization-study.md`
|
||
- Phase 143-loopvocab P0/P1: loop 内 if/break/continue の語彙追加(DONE)
|
||

|
||
- `docs/development/current/main/phases/phase-145-anf/README.md`
|
||

|
||
## Resolved (historical)
|
||
|
||
### WSL EXDEV / cargo build failure (resolved)
|
||
|
||
- 2025-12-18: `Invalid cross-device link (os error 18)` により `cargo build` が失敗する事象があったが、`wsl --shutdown` 再起動後に復旧。
|
||
- 再発時のワークアラウンド: `tools/build_llvm.sh` は EXDEV を避けるため `TMPDIR` を `target/...` 配下へ寄せる。
