# 🚨 WASM/AOT WASM 現在の問題・制限事項
|
|
|
|
|
|
|
|
|
|
|
|
## 📅 最終更新: 2025-08-15
|
|

|
|
|
|
|
|
|
## 🔴 **緊急度: 高**
|
|
|
|
|
|
|
|
|
|
|
|
### 1. **BoxCall命令未実装**
|
|
|
|
|
|
**問題**: `toString()`, `print()` 等のBox メソッド呼び出しがWASMで未対応
|
|
|
|
|
|
|
|
|
|
|
|
**エラー例**:
|
|
|
|
|
|
```bash
|
|
|
|
|
|
❌ WASM compilation error: Unsupported instruction: BoxCall {
|
|
|
|
|
|
dst: Some(ValueId(6)),
|
|
|
|
|
|
box_val: ValueId(4),
|
|
|
|
|
|
method: "toString",
|
|
|
|
|
|
args: [],
|
|
|
|
|
|
effects: EffectMask(16)
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
**影響範囲**:
|
|
|
|
|
|
- 基本的なBox操作(toString, print等)が全て使用不可
|
|
|
|
|
|
- 実用的なNyashプログラムがWASMでコンパイル不可
|
|
|
|
|
|
|
|
|
|
|
|
**修正必要ファイル**:
|
|
|
|
|
|
- `src/backend/wasm/codegen.rs`: BoxCall命令の実装
|
|
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
### 2. **wasmtimeバージョン互換性問題**
|
|
|
|
|
|
**問題**: コンパイル時wasmtimeとシステムwasmtimeのバージョン不一致
|
|
|
|
|
|
|
|
|
|
|
|
**エラー例**:
|
|
|
|
|
|
```bash
|
|
|
|
|
|
Error: Module was compiled with incompatible Wasmtime version '18.0.4'
|
|
|
|
|
|
System wasmtime: 35.0.0
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
**原因**:
|
|
|
|
|
|
```toml
|
|
|
|
|
|
# Cargo.toml
|
|
|
|
|
|
wasmtime = "18.0" # コンパイル時
|
|
|
|
|
|
|
|
|
|
|
|
# システム
|
|
|
|
|
|
wasmtime 35.0.0 # 実行時
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
**影響**:
|
|
|
|
|
|
- AOT (.cwasm) ファイルが実行不可
|
|
|
|
|
|
- 配布用実行ファイル生成失敗
|
|
|
|
|
|
|
|
|
|
|
|
**修正策**:
|
|
|
|
|
|
1. **短期**: Cargo.tomlのwasmtimeバージョン更新
|
|
|
|
|
|
2. **長期**: 互換性保証メカニズム実装
|
|
|
|
|
|
|
|

|

|
|
|
|
### 3. **WASM出力バイナリエラー**
|
|
|
|
|
|
**問題**: WAT → WASM変換でUTF-8エラー発生
|
|
|
|
|
|
|
|
|
|
|
|
**エラー例**:
|
|
|
|
|
|
```bash
|
|
|
|
|
|
❌ Generated WASM is not valid UTF-8
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
**推測原因**:
|
|
|
|
|
|
- WAT形式の生成に問題
|
|
|
|
|
|
- wabt crateとの連携ミス
|
|
|
|
|
|
|
|
|
|
|
|
**修正必要箇所**:
|
|
|
|
|
|
- `src/backend/wasm/codegen.rs`: WAT生成ロジック
|
|
|
|
|
|
- WASM バイナリ出力パイプライン
|
|
|
|
|

## 🟠 **緊急度: 中**
|
|
|
|
|
|
|
|
|
|
|
|
### 4. **RuntimeImports未実装機能**
|
|
|
|
|
|
**問題**: WASMで必要なランタイム関数が部分実装
|
|
|
|
|
|
|
|
|
|
|
|
**未実装機能**:
|
|
|
|
|
|
- Box メモリ管理 (malloc, free)
|
|
|
|
|
|
- 型キャスト・変換
|
|
|
|
|
|
- 配列・Map操作
|
|
|
|
|
|
- 例外ハンドリング
|
|
|
|
|
|
|
|
|
|
|
|
**ファイル**: `src/backend/wasm/runtime.rs`
|
|
|
|
|
|
|
|
|
|
|
|
---
|
|
|
|
|
|
|
|
|
|
|
|
### 5. **メモリ管理最適化不足**
|
|
|
|
|
|
**問題**: WASMメモリレイアウトが非効率
|
|
|
|
|
|
|
|
|
|
|
|
**課題**:
|
|
|
|
|
|
- Box ヘッダーサイズ固定 (12 bytes)
|
|
|
|
|
|
- ガベージコレクション未実装
|
|
|
|
|
|
- メモリ断片化対策なし
|
|
|
|
|
|
|
|
|
|
|
|
**ファイル**: `src/backend/wasm/memory.rs`
|
|
|
|
|
|
|
|

|

|
|
## 🟡 **緊急度: 低**
|
|
|
|
|
|
|
|
|
|
|
|
### 6. **デバッグ情報不足**
|
|
|
|
|
|
**問題**: WASM実行時のエラー情報が不十分
|
|
|
|
|
|
|
|
|
|
|
|
**改善点**:
|
|
|
|
|
|
- ソースマップ生成
|
|
|
|
|
|
- スタックトレース詳細化
|
|
|
|
|
|
- ブレークポイント対応
|

|

|
|
|
|
|
|
|
|
|
|
### 7. **最適化機能未実装**
|
|
|
|
|
|
**問題**: WASM出力が最適化されていない
|
|
|
|
|
|
|
|
|
|
|
|
**未実装最適化**:
|
|
|
|
|
|
- デッドコード除去
|
|
|
|
|
|
- インライン展開
|
|
|
|
|
|
- 定数畳み込み
