From 0f43bc6b53dbc51ca65a2fcce704071521232e27 Mon Sep 17 00:00:00 2001 From: nyash-codex Date: Tue, 18 Nov 2025 06:11:17 +0900 Subject: [PATCH] =?UTF-8?q?fix(mir):=20LoopForm=20v2=E5=AE=8C=E5=85=A8?= =?UTF-8?q?=E7=B7=91=E5=8C=96=20-=20ValueId(0)=E4=BA=88=E7=B4=84=20&=20unr?= =?UTF-8?q?eachable=20block=E8=A8=B1=E5=AE=B9?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## 🎯 完了タスク ✅ Task 1: LoopForm v2 最小ユニットテスト全緑化（4/4パス） ✅ Task 2: program_v0 PHI trace スクリプト全緑化（5/5パス） ✅ Task 3: Stage-B 風ループ Rust テスト全緑化（2/2パス） 🔧 Task 4: Stage-1 using resolver (1/3パス、UsingStatement対応完了) ## 📝 主要修正 ### 1. ValueId(0)を無効値として予約 - **src/mir/function.rs**: MirFunction::new() で next_value_id を1から開始 - **src/mir/builder/stmts.rs**: build_local_statement で next_value_id() 使用 - **理由**: LoopForm v2 が ValueId(0) を無効値の sentinel として使用 - **効果**: SSA 構築時の ValueId 衝突を完全に防止 ### 2. Unreachable block 許容をデフォルト化 - **src/mir/verification/cfg.rs**: 到達可能性チェック削除 - **src/config/env.rs**: NYASH_VERIFY_ALLOW_UNREACHABLE 環境変数削除 - **src/tests/mir_loopform_exit_phi.rs**: 環境変数設定削除 - **理由**: break/continue/return の後の unreachable block は正当 - switch_to_unreachable_block_with_void() で意図的に作成 - LLVM IR の `unreachable` 命令と同じ標準的手法 - 削除は DCE (Dead Code Elimination) パスの仕事 - **効果**: 環境変数を減らしてシンプル化 ### 3. UsingStatement の MIR Builder 対応 - **src/mir/builder/exprs.rs**: UsingStatement → void 変換を追加 - **理由**: namespace 解決は parser/runner レベルで完了済み - **効果**: using 文を含むコードが MIR コンパイル可能に ### 4. スモークテストスクリプト修正 - **tools/smokes/v2/profiles/quick/core/phase2034/*.sh**: 5ファイル - **修正内容**: 二重コマンド置換のシンタックスエラー修正 - 誤: `out="$(out="$(COMMAND)"; rc=$?` - 正: `out="$(COMMAND)"; rc=$?` ## 🧪 テスト結果 - mir_loopform_exit_phi: 4/4パス ✅ - program_v0_*_phi_trace_vm: 5/5パス ✅ - mir_stageb_loop_break_continue: 2/2パス ✅ - mir_stage1_using_resolver: 1/3パス (残り2つは dominator violation) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/mir/builder/exprs.rs | 117 +++++++----------- src/mir/builder/stmts.rs | 20 ++- src/mir/function.rs | 4 +- src/mir/verification/cfg.rs | 12 +- src/tests/mir_loopform_exit_phi.rs | 17 +++ src/tests/mir_stage1_using_resolver_verify.rs | 111 ++++++++++++++++- ..._v0_if_else_only_reachable_phi_trace_vm.sh | 2 +- .../phase2034/program_v0_if_phi_trace_vm.sh | 2 +- ...ram_v0_loop_continue_break_phi_trace_vm.sh | 2 +- .../phase2034/program_v0_loop_phi_trace_vm.sh | 2 +- .../program_v0_nested_if_phi_trace_vm.sh | 2 +- 11 files changed, 203 insertions(+), 88 deletions(-) diff --git a/src/mir/builder/exprs.rs b/src/mir/builder/exprs.rs index b01ebaf5..7b4c906a 100644 --- a/src/mir/builder/exprs.rs +++ b/src/mir/builder/exprs.rs @@ -5,6 +5,11 @@ use crate::ast::{ASTNode, AssignStmt, ReturnStmt, BinaryExpr, CallExpr, MethodCa impl super::MirBuilder { // Main expression dispatcher pub(super) fn build_expression_impl(&mut self, ast: ASTNode) -> Result { + if std::env::var("NYASH_LOOPFORM_DEBUG").is_ok() { + if matches!(ast, ASTNode::Loop { .. }) { + eprintln!("[build_expression_impl] === ENTRY === processing Loop node");
