Extend Phase 132's loop(true) + post-loop to accept multiple assignments:
Goal: `x=0; loop(true){ x=1; break }; x=x+2; x=x+3; return x` → exit code 6
Implementation:
- Extended loop_true_break_once.rs pattern detection (len() == 2 → len() >= 2)
- Added iterative assignment lowering (for loop over post_nodes)
- Reused Phase 130's lower_assign_stmt for each assignment
- Maintained ExitMeta DirectValue mode (PHI-free)
Changes:
- apps/tests/phase133_loop_true_break_once_post_multi_add_min.hako (new fixture)
- tools/smokes/v2/profiles/integration/apps/phase133_*_multi_add_*.sh (new smokes)
- src/mir/control_tree/normalized_shadow/loop_true_break_once.rs (+30 lines)
- docs/development/current/main/phases/phase-133/README.md (new documentation)
- docs/development/current/main/10-Now.md (Phase 133 entry added)
Scope (Phase 130 baseline):
- ✅ x = <int literal>
- ✅ x = y (variable copy)
- ✅ x = x + <int literal> (increment)
- ❌ Function calls / general expressions (future phases)
Design principles:
- Minimal change: ~30 lines added
- SSOT preservation: env_post_k remains single source of truth
- Reuse: Leveraged existing lower_assign_stmt
- Fail-Fast: Contract violations trigger freeze_with_hint
Test results:
- cargo test --lib: 1176 PASS
- Phase 133 VM: PASS (exit code 6)
- Phase 133 LLVM EXE: PASS (exit code 6)
- Phase 132 regression: PASS (exit code 3)
- Phase 131 regression: PASS (exit code 1)
- Phase 97 regression: PASS
Architecture maintained:
- 5-function structure unchanged (main/loop_step/loop_body/k_exit/post_k)
- PHI-free DirectValue mode
- Zero changes to ExitMeta, merge logic, or JoinIR contracts

Smokes v2 — Minimal Runner and Policy
Policy
- Use [SKIP:] prefix for environment/host dependent skips.
- Examples: [SKIP] hakorune not built, [SKIP:env] plugin path missing
- Keep reasons short and stable to allow grep-based canaries.
- Prefer JSON-only output in CI: set
NYASH_JSON_ONLY=1to avoid noisy logs. - Diagnostics lines like
[provider/select:*]are filtered by default inlib/test_runner.sh.- Toggle: set
HAKO_SILENT_TAGS=0to disable filtering and show raw logs.HAKO_SHOW_CALL_LOGS=1also bypasses filtering.
- Toggle: set
Helpers
tools/smokes/v2/lib/mir_canary.shprovides:extract_mir_from_output— between [MIR_BEGIN]/[MIR_END]assert_has_tokens,assert_skip_tag,assert_order,assert_token_count
tools/lib/canary.shprovides minimal, harness-agnostic aliases:extract_mir_between_tags— same asextract_mir_from_outputrequire_tokens token...— fail if any token missing
Notes
- Avoid running heavy integration smokes in CI by default. Use
--profile quick. - When a test depends on external tools (e.g., LLVM), prefer
[SKIP:<reason>]over failure. - Stage‑B/selfhost canaries(
stage1_launcher_*,phase251*など)は Stage‑3 デフォルト環境で安定しないため、quick プロファイルでは[SKIP:stageb]として扱い、必要に応じて別プロファイル(integration/full)で個別に実行する。 - Selfhost quick カバレッジは最小 1 本(
core/selfhost_minimal.sh)に絞り、Stage‑3 + JoinIR 前提で Stage‑B→VM を通るかだけを確認する。 - S3 backend 向けの長尺テスト群も quick 向きではないため、timeout を短く保ちたい場合は
[SKIP:slow]にして別途ローカルで回すことを推奨する。
Quick tips
- EXE-heavy cases (e.g.,
phase2100/*) may take longer. When running quick with these tests, pass a larger timeout like--timeout 120. - Smokes v2 auto-cleans temporary crate EXE objects created under
/tmp(pattern:ny_crate_backend_exe_*.o) after the run.
Developer Notes
- JoinIR If/Select (Phase 33): A/B test with
NYASH_FEATURES=stage3 HAKO_JOINIR_IF_SELECT=1 ./target/release/hakorune apps/tests/joinir_if_select_simple.hako(dev-only、CI対象外。NYASH_JOINIR_CORE は deprecated/無視)
