From bf4b87526e37100c5063e940b86a35a468341131 Mon Sep 17 00:00:00 2001 From: Moe Charm Date: Tue, 26 Aug 2025 05:49:23 +0900 Subject: [PATCH] phase(9.78h): stabilize MIR/VM pipeline MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add MIR26 doc≡code sync test (tests/mir_instruction_set_sync.rs) - Quiet snapshots; filter plugin/net logs; golden all green - Delegate VM phi selection to LoopExecutor (borrow-safe) - ResultBox migration: remove legacy box_trait::ResultBox paths - VM BoxRef arithmetic fallbacks via toString().parse::() - Bridge BoxCall(InstanceBox) to Class.method/arity in VM - Fix Effects purity (READ -> readonly, not pure) - Mark Catch as CONTROL to prevent DCE; Try/Catch test green - Add env-gated debug logs (effects, verifier, mir-printer, trycatch, ref, bin) - Update CURRENT_TASK with progress and next steps --- CLAUDE.md | 17 ------- docs/development/current/CURRENT_TASK.md | 48 +++++++++++++++++++- src/backend/vm.rs | 57 +++++++++++------------- src/backend/vm_boxcall.rs | 13 +----- src/backend/vm_instructions.rs | 31 ++++++++++--- src/backend/vm_values.rs | 39 ++++++++++++++++ src/cli.rs | 3 ++ src/debug/log.rs | 22 +++++++++ src/debug/mod.rs | 2 + src/lib.rs | 1 + src/main.rs | 1 + src/mir/builder.rs | 9 ++++ src/mir/effect.rs | 13 +++++- src/mir/instruction.rs | 2 +- src/mir/instruction_introspection.rs | 35 +++++++++++++++ src/mir/mod.rs | 23 ++++------ src/mir/printer.rs | 5 +++ src/mir/verification.rs | 5 +++ src/runner.rs | 26 ++++++++--- tests/mir_instruction_set_sync.rs | 46 +++++++++++++++++++ tools/snapshot_mir.sh | 7 ++- 21 files changed, 310 insertions(+), 95 deletions(-) create mode 100644 src/debug/log.rs create mode 100644 src/debug/mod.rs create mode 100644 src/mir/instruction_introspection.rs create mode 100644 tests/mir_instruction_set_sync.rs diff --git a/CLAUDE.md b/CLAUDE.md index ba1e259f..659125dc 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -484,23 +484,6 @@ ls src/backend/ | grep "^vm_" | xargs -I{} wc -l src/backend/{} **根本原因：** Claudeのコマンド再構築機能のバグ（`pattern`ではなく`op`フィールドを使用） -### 💡 実践的な使い分けガイド -
