## 修正内容 ### 1. Stage-B パーサー修正（偶然の回避） - **ファイル**: - `lang/src/compiler/parser/expr/parser_expr_box.hako` - `lang/src/compiler/parser/stmt/parser_control_box.hako` - **問題**: ネストループで gpos が正しく進まず、loop の cond/body が壊れる - **回避策**: new 式のメソッドチェーン処理追加で別ループを導入 - **結果**: MIR 生成が変わって VM gpos バグを回避 ### 2. delegate パス動作確認 - **テスト**: `/tmp/loop_min.hako` → rc=10 ✅ - **MIR構造**: 正しい PHI/compare/binop を生成 - **チェーン**: hakorune parser → Rust delegate → LLVM EXE 完動 ### 3. ドキュメント追加 - `docs/development/analysis/` - delegate 分析 - `docs/development/guides/` - ループテストガイド - `docs/development/testing/` - Stage-B 検証報告 ### 4. カナリーテスト追加 - `tools/smokes/v2/profiles/quick/core/phase2100/` 配下に複数追加 - emit_boxcall_length_canary_vm.sh - stageb_parser_loop_json_canary_vm.sh - 他 ### 受け入れ基準 - ✅ delegate パス: rc=10 返す - ✅ FORCE パス: rc=10 返す（既存） - ✅ MIR 構造: 正しい PHI incoming と compare - ✅ 既定挙動: 不変（dev トグルのみ） 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# Phase 21.5 — Optimization (ny-llvm crate line)
|
||
|
||
Scope
|
||
- Optimize hot paths for the crate (ny-llvmc) line using Hakorune scripts only.
|
||
- Preserve default behavior; all risky changes behind dev toggles.
|
||
- Measure EXE runtime (build once, run many) to avoid toolchain overhead noise.
|
||
|
||
Targets (initial)
|
||
- loop: integer accumulations (no I/O)
|
||
- strlen: FAST=1 path (pointer → nyrt_string_length)
|
||
- box: construct/destroy minimal boxes (String/Integer)
|
||
|
||
Methodology
|
||
- Build once via ny-llvmc; time execution only (`--exe` mode).
|
||
- Runs: 3–5; report median and average (target ≥ 100ms per run).
|
||
- Observe NYASH_VM_STATS=1 (inst/compare/branch) where relevant to correlate structure and runtime.
|
||
|
||
Commands (examples)
|
||
- tools/perf/phase215/bench_loop.sh --runs 5
|
||
- tools/perf/phase215/bench_strlen.sh --runs 5 --fast 1
|
||
- tools/perf/phase215/run_all.sh --runs 5 --timeout 120
|
||
|
||
Dev Toggles (keep OFF by default)
|
||
- NYASH_LLVM_FAST=1 (strlen FAST)
|
||
- HAKO_MIR_BUILDER_JSONFRAG_NORMALIZE=1 (normalize)
|
||
- HAKO_MIR_BUILDER_NORMALIZE_TAG=1 (tag, test-only)
|
||
|
||
Exit Criteria
|
||
- Representative microbenches stable (≤ 5% variance) and ≥ 80% of C baselines.
|
||
- No regression in EXE canaries (loop/print/strlen FAST) and VM parity canaries.
