BinOpKind 拡張 (src/mir/join_ir.rs:147-154) - Or/And variant 追加（論理演算対応） - Phase 27.1 実験的拡張として最小限の変更 3. テストインフラ追加 (src/tests/mir_joinir_funcscanner_trim.rs) - auto_lowering テスト: #[ignore] + NYASH_JOINIR_EXPERIMENT=1 トグル - type_sanity テスト: 常時実行の軽量テスト 4. ドキュメント完備 (docs/private/roadmap2/phases/phase-27.1-joinir/) - IMPLEMENTATION_LOG.md: 技術メモ + BinOpKind 拡張決定の記録 - TASKS.md: 実装ステップ進捗管理 検証結果: - ✅ ビルド成功 (リリースビルド 55.75s) - ✅ type_sanity テスト PASS - ✅ 既存 JoinIR テスト全て PASS (mir_joinir_min, mir_joinir_skip_ws) - ✅ トグル OFF で本線影響なし確認済み トグル制御: - NYASH_JOINIR_EXPERIMENT=1 で JoinIR 変換有効化 - デフォルトは従来の MIR/LoopForm 維持 次のステップ: - C-2: トグル ON での動作確認 - D-1: ベースライン緑度確認 - E-1: README 更新 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/mir/join_ir.rs | 259 +++++++++++++++++++++++ src/tests/mir_joinir_funcscanner_trim.rs | 100 +++++++++ src/tests/mod.rs | 3 +- 3 files changed, 361 insertions(+), 1 deletion(-) create mode 100644 src/tests/mir_joinir_funcscanner_trim.rs diff --git a/src/mir/join_ir.rs b/src/mir/join_ir.rs index c57b6495..4391dbcb 100644 --- a/src/mir/join_ir.rs +++ b/src/mir/join_ir.rs @@ -149,6 +149,8 @@ pub enum BinOpKind { Sub, Mul, Div, + Or, // Phase 27.1: 論理OR (bool || bool) + And, // Phase 27.1: 論理AND (bool && bool) } /// 比較演算種別 @@ -510,6 +512,263 @@ pub fn lower_skip_ws_to_joinir(module: &crate::mir::MirModule) -> Option b) { +/// local ch = str.substring(e - 1, e) +/// if ch == " " || ch == "\t" || ch == "\n" || ch == "\r" { +/// e = e - 1 +/// } else { +/// break +/// } +/// } +/// return substring(b, e) +/// } +/// +/// // JoinIR (変換後): +/// fn trim_main(s_param, k_exit) { +/// str = "" + s_param +/// n = str.length() +/// b = skip_whitespace(str, 0) +/// e_init = n +/// loop_step(str, b, e_init, k_exit) +/// } +/// +/// fn loop_step(str, b, e, k_exit) { +/// cond = (e > b) +/// if cond { +/// ch = str.substring(e - 1, e) +/// is_space = (ch == " " || ch == "\t" || ch == "\n" || ch == "\r") +/// if is_space { +/// e_next = e - 1 +/// loop_step(str, b, e_next, k_exit) +/// } else { +/// k_exit(e) +/// } +/// } else { +/// k_exit(e) +/// } +/// } +/// ``` +pub fn lower_funcscanner_trim_to_joinir(module: &crate::mir::MirModule) -> Option { + // Step 1: "FuncScannerBox.trim/1" を探す + let target_func = module.functions.get("FuncScannerBox.trim/1")?;
