- タスク:
- ny_bench.nyash のケース整理（関数呼出/Map set-get/branch）
- ny_bench.hako のケース整理（関数呼出/Map set-get/branch）
- compare: VM vs JIT（ウォームアップ付き）

@ -25,7 +25,7 @@ Deliverables
- Lowering updates: Branch/Jump hook uses real block IDs; Compare emits b1-friendly shape.
- Env flags: Reuse `NYASH_JIT_EXEC/THRESHOLD/STATS/DUMP`; guard hostcalls by `NYASH_JIT_HOSTCALL`.
- Docs: Update execution-backends.md with “JIT control-flow coverage (10.7)”.
- Examples: `examples/jit_branch_demo.nyash` (if/loop minimal).
- Examples: `examples/jit_branch_demo.hako` (if/loop minimal).

@ -59,13 +59,13 @@ Implementation Plan (Tasks)
- For Branch/Jump, call builder with mapped blocks and condition value hint.
- Compare: emit b1 icmp; when Compare is used as value elsewhere, allow i64 extend as needed.
- T4: Minimal PHI support for a single merge (optional; guarded by env `NYASH_JIT_PHI_MIN=1`).
- T5: Add `examples/jit_branch_demo.nyash` with: `if (a < b) { return 1 } else { return 2 }` and a small loop with early `return`.
- T5: Add `examples/jit_branch_demo.hako` with: `if (a < b) { return 1 } else { return 2 }` and a small loop with early `return`.
- T6: Docs update: execution-backends.md “JIT coverage 10.7” + env flags.
- T7: Bench (optional): integrate into `--benchmark` with JIT warmup when `NYASH_JIT_EXEC=1`.
Validation
- Build matrix: with/without `cranelift-jit` feature.
- Smoke tests: run `jit_branch_demo.nyash` with `NYASH_JIT_EXEC=1 NYASH_JIT_THRESHOLD=1`.
- Smoke tests: run `jit_branch_demo.hako` with `NYASH_JIT_EXEC=1 NYASH_JIT_THRESHOLD=1`.
- Fallback verification: force a path with unsupported op to confirm VM fallback.
- GC/scheduler: ensure safepoint path still works (unchanged).
