+# → 算術演算・print・return正常変換
+
+# ❌ 未対応構文

- Rust は「コンパイラ本体」のみ。実行は純WASM+ホストimport(env.print 等)。

+### WASM Module Structure

- - PoC2: RefNew/RefSet/RefGet(Phase 6 と整合)で `print(o.x)`
- - PoC3: Weak/Barrier の下地(WeakLoad は当面 Some 相当、Barrier は no-op)

## Acceptance Criteria
-- PoC1: 生成WASMを wasmtime で実行し、戻り値・print 出力が期待通り
-- PoC2: `o = new Obj(); o.x = 1; print(o.x)` 相当が Ref 系命令で動作
-- PoC3: Weak/Barrier のダミー命令を含むWASMが生成・実行(実質 no-op で可)
-- CLI 連携を行う場合、未対応箇所は明瞭なエラー/誘導メッセージ
-## Tests
-- tests/wasm_poc1_basic.sh(または Rust integration)
- - MIR → WASM の出力を wasmtime で実行し、終了コード/標準出力を検証
-- tests/wasm_poc2_ref_ops.sh
- - RefNew/RefSet/RefGet 経由の `print(o.x)` を確認
-- Node/ブラウザ用:ヘッドレス実行で `env.print` の呼び出しを検証する最小スクリプト
+### PoC1 (Basic Operations)
+- ✅ **WASM Generation**: 基本MIR命令がvalid WASMに変換される
+- ✅ **Wasmtime Execution**: `wasmtime run output.wasm` で正常実行
+- ✅ **Arithmetic**: `print(42 + 8)` → stdout: `50`
+- ✅ **Control Flow**: if文、loop文が正しく動作
-## Out of Scope
-- 本格GC/Weak無効化、fini/Pin/Unpin、JIT/AOT の高度最適化、複雑な文字列ABI
+### PoC2 (Object Operations)
+- ✅ **Memory Allocation**: RefNew でヒープメモリが正しく割り当てられる
+- ✅ **Field Access**: `o = new DataBox(); o.value = 1; print(o.value)` → stdout: `1`
+- ✅ **Memory Layout**: Box構造がメモリ上で正しいレイアウトになる
-## References
-- docs/予定/native-plan/README.md(Phase 8)
-- docs/説明書/wasm/*
+### PoC3 (Extension Foundation)
+- ✅ **Weak Reference**: WeakNew/WeakLoad命令がno-opとして動作
+- ✅ **Memory Barriers**: BarrierRead/Write命令が含まれても実行できる
+- ✅ **Future Operations**: FutureNew/Await が即座完了として動作
+
+### CLI Integration
+- ✅ **Command Line**: `nyash --backend wasm test.nyash` で実行可能
+- ✅ **File Output**: `nyash --backend wasm --output test.wasm test.nyash` でファイル出力
+- ✅ **Error Messages**: 未対応機能の明確なエラーメッセージ
+
+## Test Strategy
+
+### Unit Tests (Rust)
+```rust
+// tests/wasm_codegen_tests.rs
+#[test]
+fn test_basic_arithmetic_codegen() {
+ let mir = /* 42 + 8 のMIR */;
+ let wasm_bytes = WasmBackend::new().compile_module(mir).unwrap();
+ let result = wasmtime_execute(&wasm_bytes);
+ assert_eq!(result.stdout, "50\n");
+}
+
+#[test]
+fn test_ref_operations_codegen() {
+ let mir = /* object field access のMIR */;
+ let wasm_bytes = WasmBackend::new().compile_module(mir).unwrap();
+ let result = wasmtime_execute(&wasm_bytes);
+ assert_eq!(result.stdout, "1\n");
+}
+```
+
+### Integration Tests
+- `tests/wasm_poc1_arithmetic.nyash` → MIR → WASM → wasmtime実行
+- `tests/wasm_poc2_objects.nyash` → RefNew/RefGet/RefSet使用 → WASM実行
+- `tests/wasm_poc3_features.nyash` → Weak/Future命令含む → WASM実行
+
+### Browser Testing
+```html
+
+
+```
+
+## Technical Dependencies
+
+### Required Crates
+- `wabt` - WAT ↔ WASM conversion
+- `wasmtime` - Runtime execution (dev dependency)
+- `wat` - WAT text format parsing (optional)
+
+### WASM Tools
+- `wasmtime` CLI - Local execution & testing
+- `wasm-objdump` - Binary inspection (optional)
+- `wasm-validate` - Validation (optional)
+
+## Development Notes
+
+### Memory Management Strategy
+1. **Phase 8.3**: Simple bump allocator (no free)
+2. **Future**: Free list allocator
+3. **Future**: Generational GC integration
+
+### Type System Mapping
+| Nyash Type | MIR Type | WASM Type | Memory Layout |
+|-----------|----------|-----------|---------------|
+| IntegerBox | Integer | i32 | 4 bytes |
+| BoolBox | Bool | i32 | 4 bytes (0/1) |
+| DataBox | Box("DataBox") | i32 | ptr to [type_id, field_count, fields...] |
+
+### Debugging Support
+- WAT output for human inspection
+- Source map generation (future)
+- WASM stack trace integration (future)
+
+## Out of Scope (Phase 8)
+- 本格的なGC(mark-sweep、generational等)
+- Weak参照の実際の無効化メカニズム
+- Pin/Unpin、fini()のカスケード処理
+- JIT/AOTコンパイル最適化
+- 複雑な文字列ABI(UTF-8、length prefixed等)
+- WASI I/O インターフェース(file、network等)
+
+## References & Dependencies
+- **Phase 6**: RefNew/RefGet/RefSet MIR命令 (実装済み)
+- **Phase 7**: FutureNew/Await MIR命令 (実装済み)
+- docs/予定/native-plan/README.md(Phase 8詳細)
