From cf60e7cbbcd9822bc72ad222ab06bc7676cfe361 Mon Sep 17 00:00:00 2001 From: nyash-codex Date: Sun, 23 Nov 2025 06:06:16 +0900 Subject: [PATCH] =?UTF-8?q?feat(joinir):=20Phase=2027.1=20-=20minimal=5Fss?= =?UTF-8?q?a=5Fskip=5Fws=20JoinIR=E5=A4=89=E6=8F=9B=E5=AE=9F=E8=A3=85?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 目的: - Phase 26-H で確立した JoinIR 型システムを実用ループに適用 - minimal_ssa_skip_ws.hako (ネストif + loop(1==1) + break) の変換実装 - トグル制御 (NYASH_JOINIR_EXPERIMENT=1) で実験的に有効化 実装内容: - src/mir/join_ir.rs: lower_skip_ws_to_joinir() 関数追加 (187行) - skip 関数: i_init=0, n=s.length(), loop_step 呼び出し - loop_step 関数: ネストif処理 + 2つのbreak経路 + 再帰呼び出し - 固定ValueId割り当て (3000-3002: skip, 4000-4011: loop_step) - src/tests/mir_joinir_skip_ws.rs: テストインフラ追加 - mir_joinir_skip_ws_auto_lowering: トグル制御実験用 (#[ignore]) - mir_joinir_skip_ws_type_sanity: 常時実行の型妥当性チェック - Stage-3 parser 有効化 (local キーワード対応) - src/tests/mod.rs: テストモジュール登録 検証結果: ✅ トグル ON: JoinIR 変換成功、2関数生成確認 ✅ トグル OFF: 既存テスト影響なし (1 passed; 1 ignored) ✅ 本線テスト: 367 passed (既存失敗は Phase 27.1 と無関係) Phase 26-H との違い: - 複雑度: 簡単 (joinir_min) → 中程度 (skip_ws) - break 箇所: 1箇所 → 2箇所 (ネストif内) - ループ条件: i < 3 → 1 == 1 (定数true) - 変数: i のみ → s, i, n, ch (4変数) 次フェーズ: - Phase 27.2+: MIR 解析による自動検出 (現在は固定実装) - Phase 28: 一般化された変換器実装 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/mir/join_ir.rs | 188 ++++++++++++++++++++++++++++++++ src/tests/mir_joinir_skip_ws.rs | 95 ++++++++++++++++ src/tests/mod.rs | 1 + 3 files changed, 284 insertions(+) create mode 100644 src/tests/mir_joinir_skip_ws.rs diff --git a/src/mir/join_ir.rs b/src/mir/join_ir.rs index 25b65a2e..c57b6495 100644 --- a/src/mir/join_ir.rs +++ b/src/mir/join_ir.rs @@ -322,6 +322,194 @@ pub fn lower_min_loop_to_joinir(module: &crate::mir::MirModule) -> Option= n { break } +/// local ch = s.substring(i, i + 1) +/// if ch == " " { i = i + 1 } else { break } +/// } +/// return i +/// } +/// } +/// +/// // JoinIR (変換後): +/// fn skip(s_param, k_exit) { +/// i_init = 0 +/// n = s_param.length() +/// loop_step(s_param, i_init, n, k_exit) +/// } +/// +/// fn loop_step(s, i, n, k_exit) { +/// if i >= n { +/// k_exit(i) // break +/// } else { +/// ch = s.substring(i, i + 1) +/// if ch == " " { +/// loop_step(s, i + 1, n, k_exit) // continue +/// } else { +/// k_exit(i) // break +/// } +/// } +/// } +/// ``` +pub fn lower_skip_ws_to_joinir(module: &crate::mir::MirModule) -> Option { + // Step 1: "Main.skip/1" を探す + let target_func = module.functions.get("Main.skip/1")?;
