264940ef51 feat(llvm/phi): Phase 278 P0 - remove deprecated PHI debug env vars 
## Changes
- debug_helper.py: Remove backward compatibility (warning → error + exit 1)
- environment-variables.md: Migrate deprecated section with migration guide
- phase278_p0_deprecated_env_fail.sh: Add smoke test for deprecated var detection

## Removed Variables (5)
- NYASH_LLVM_PHI_DEBUG
- NYASH_PHI_TYPE_DEBUG

- NYASH_LLVM_TRACE_PHI
- NYASH_LLVM_VMAP_TRACE

## SSOT Variables (3) - Unchanged
- NYASH_LLVM_DEBUG_PHI=1
- NYASH_LLVM_DEBUG_PHI_TRACE=1
- NYASH_LLVM_PHI_STRICT=1

## Benefits
- ✅ Deprecated vars cause fail-fast error (not silent)
- ✅ Error messages include replacement hints
- ✅ Documentation reflects removal (migration guide included)
- ✅ Smoke test verifies deprecated var rejection
- ✅ No regressions in existing tests

## Testing
✅ Test 1: Deprecated NYASH_LLVM_PHI_DEBUG rejected

757193891f feat(llvm/phi): Phase 277 P1 - fail-fast validation for PHI strict mode 
## Summary
Implemented fail-fast validation for PHI ordering and value resolution in strict mode.

## Changes

### P1-1: Strict mode for "PHI after terminator"
- File: `src/llvm_py/phi_wiring/wiring.py::ensure_phi`
- Behavior: `NYASH_LLVM_PHI_STRICT=1` → RuntimeError if PHI created after terminator
- Default: Warning only (no regression)

### P1-2: Strict mode for "fallback 0"
- File: `src/llvm_py/phi_wiring/wiring.py::wire_incomings`
- Behavior: Strict mode forbids silent fallback to 0 (2 locations)
  - Location 1: Unresolvable incoming value
  - Location 2: Type coercion failure
- Error messages point to next debug file: `llvm_builder.py::_value_at_end_i64`

### P1-3: Connect verify_phi_ordering() to execution path
- File: `src/llvm_py/builders/function_lower.py`
- Behavior: Verify PHI ordering after all instructions emitted
- Debug mode: Shows "✅ All N blocks have correct PHI ordering"
- Strict mode: Raises RuntimeError with block list if violations found

## Testing
✅ Test 1: strict=OFF - passes without errors
✅ Test 2: strict=ON - passes without errors (no violations in test fixtures)
✅ Test 3: debug mode - verify_phi_ordering() connected and running

## Scope
- LLVM harness (Python) changes only
- No new environment variables (uses existing 3 from Phase 277 P2)
- No JoinIR/Rust changes (root fix is Phase 279)
- Default behavior unchanged (strict mode opt-in)

## Next Steps
- Phase 278: Remove deprecated env var support
- Phase 279: Root fix - unify "2本のコンパイラ" pipelines

9a76a199ee feat(phase276-p0): Quick Win improvements - type helper SSOT + debug cleanup 
Phase 276 P0 post-Phase 275 robustness improvements:

1. Debug cleanup (wiring.py L100-103):
   - Remove traceback.format_stack() output
   - Cleaner debug logs after Phase 275 completion

2. box_from_f64 usage investigation:
   - Confirmed ZERO usage (Rust/Python/MIR)
   - Ready for deletion (Phase 275 unboxed double SSOT)
   - crates/nyash_kernel/src/lib.rs L244-252, L971-982

3. Type resolution SSOT (⭐ most important):
   - New file: src/llvm_py/phi_wiring/type_helper.py (72 lines)
   - Unified 3 duplicate logic sites:
     * tagging.py: inst.get("dst_type") → type_helper.get_phi_dst_type()
     * llvm_builder.py: 9 lines → 2 lines (-7)
     * wiring.py: 18 lines → 5 lines (-13)
   - Priority: MIR JSON dst_type > resolver.value_types
   - Benefits: SSOT principle, bug prevention, easy extension

4. Type mismatch warning enhancement (wiring.py L63-79):
   - CRITICAL warning for predeclared PHI type mismatch
   - PhiManager.invalidate_phi() notification
   - Early bug detection with ⚠️  marker

Effects:
- Type resolution logic: 3 sites → 1 SSOT (type_helper.py)
- Code reduction: -20 lines duplicate logic
- Robustness: SSOT principle, CRITICAL warnings, Fail-Fast
- Debuggability: cleaner logs, prominent type mismatch alerts

Testing:
- LLVM harness: exit=3 verified (/tmp/test_p275_debug2.hako)
- NYASH_PHI_TYPE_DEBUG=1: correct type resolution confirmed

Docs:
- Phase 276 P0 completion: docs/.../phase-276/P0-COMPLETION.md
- 10-Now.md: Phase 276 P0 ✅, Phase 275 P0 completed section

Next steps (Phase 277 P0 recommended):
- Delete box_from_f64 (nyash.box.from_f64, nyash.float.box_from_f64)
- Adopt dst_type_to_llvm_type() helper

e0fb6fecf6 refactor(llvm): Phase 132-P1 - FunctionLowerContext Box isolation 
Structural fix for cross-function state leakage bugs discovered in Phase 131-132.

Problem:
- Function-local state (block_end_values, def_blocks, phi_manager, caches)
  was globally managed, causing collisions across functions
- Required manual clearing via _clear_function_local_state() (~80 lines)
- Tuple-key workaround (func_name, block_id) added complexity

Solution: FunctionLowerContext Box
- Encapsulates all function-scoped state in a dedicated Box
- Automatic lifetime management (created at entry, destroyed at exit)
- Eliminates manual state clearing
- Simplifies from tuple-key to simple block_id access

Implementation:
1. Created src/llvm_py/context/function_lower_context.py (150+ lines)
   - block_end_values, def_blocks, jump_only_blocks
   - phi_manager, resolver_caches
   - Helper methods: get/set_block_snapshot(), register_def(), etc.

2. Updated function_lower.py
   - Creates context at function entry
   - Binds resolver to context for cache isolation
   - Removed _clear_function_local_state() (~80 lines)

3. Updated block_lower.py
   - Changed tuple-key (func_name, block_id) to simple block_id
   - Access via context.get_block_snapshot() / context.set_block_snapshot()

4. Updated resolver.py, phi_wiring/wiring.py, phi_wiring/tagging.py
   - All state access now through context

5. Fixed critical bug in phi_wiring/tagging.py
   - setup_phi_placeholders() was breaking context connection
   - Changed reassignment to .clear()/.update() to preserve reference

Benefits:
- ✅ Automatic state isolation (no manual clearing)
- ✅ Clear ownership (one context per function)
- ✅ Eliminated tuple-keys (simpler code)
- ✅ Prevents bugs by design (cross-function leakage impossible)

Test results:
- ✅ Phase 87 smoke test: PASS
- ✅ Phase 132 smoke test: PASS (both cases)
- ✅ STRICT mode: Works with multi-function inputs
- ✅ No regression

Files modified: 8 (2 new, 6 updated)

3f58f34592 feat(llvm): Phase 132-P0 - block_end_values tuple-key fix for cross-function isolation 
## Problem
`block_end_values` used block ID only as key, causing collisions when
multiple functions share the same block IDs (e.g., bb0 in both
condition_fn and main).

## Root Cause
- condition_fn's bb0 → block_end_values[0]
- main's bb0 → block_end_values[0] (OVERWRITES!)
- PHI resolution gets wrong snapshot → dominance error

## Solution (Box-First principle)
Change key from `int` to `Tuple[str, int]` (func_name, block_id):

```python
# Before
block_end_values: Dict[int, Dict[int, ir.Value]]

# After
block_end_values: Dict[Tuple[str, int], Dict[int, ir.Value]]
```

## Files Modified (Python - 6 files)

1. `llvm_builder.py` - Type annotation update
2. `function_lower.py` - Pass func_name to lower_blocks
3. `block_lower.py` - Use tuple keys for snapshot save/load
4. `resolver.py` - Add func_name parameter to resolve_incoming
5. `wiring.py` - Thread func_name through PHI wiring
6. `phi_manager.py` - Debug traces

## Files Modified (Rust - cleanup)

- Removed deprecated `loop_to_join.rs` (297 lines deleted)
- Updated pattern lowerers for cleaner exit handling
- Added lifecycle management improvements

## Verification

- ✅ Pattern 1: VM RC: 3, LLVM Result: 3 (no regression)
- ⚠️ Case C: Still has dominance error (separate root cause)
  - Needs additional scope fixes (phi_manager, resolver caches)

## Design Principles

- **Box-First**: Each function is an isolated Box with scoped state
- **SSOT**: (func_name, block_id) uniquely identifies block snapshots
- **Fail-Fast**: No cross-function state contamination

## Known Issues (Phase 132-P1)

Other function-local state needs same treatment:
- phi_manager.predeclared
- resolver caches (i64_cache, ptr_cache, etc.)
- builder._jump_only_blocks

447d4ea246 feat(llvm): Phase 132 - Pattern 1 exit value parity fix + Box-First refactoring 
## Phase 132: Exit PHI Value Parity Fix

### Problem
Pattern 1 (Simple While) returned 0 instead of final loop variable value (3)
- VM: RC: 3 ✅ (correct)
- LLVM: Result: 0 ❌ (wrong)

### Root Cause (Two Layers)
1. **JoinIR/Boundary**: Missing exit_bindings → ExitLineReconnector not firing
2. **LLVM Python**: block_end_values snapshot dropping PHI values

### Fix
**JoinIR** (simple_while_minimal.rs):
- Jump(k_exit, [i_param]) passes exit value

**Boundary** (pattern1_minimal.rs):
- Added LoopExitBinding with carrier_name="i", role=LoopState
- Enables ExitLineReconnector to update variable_map

**LLVM** (block_lower.py):
- Use predeclared_ret_phis for reliable PHI filtering
- Protect builder.vmap PHIs from overwrites (SSOT principle)

### Result
- ✅ VM: RC: 3
- ✅ LLVM: Result: 3
- ✅ VM/LLVM parity achieved

## Phase 132-Post: Box-First Refactoring

### Rust Side
**JoinModule::require_function()** (mod.rs):
- Encapsulate function search logic
- 10 lines → 1 line (90% reduction)
- Reusable for Pattern 2-5

### Python Side
**PhiManager Box** (phi_manager.py - new):
- Centralized PHI lifecycle management
- 47 lines → 8 lines (83% reduction)
- SSOT: builder.vmap owns PHIs
- Fail-Fast: No silent overwrites

**Integration**:
- LLVMBuilder: Added phi_manager
- block_lower.py: Delegated to PhiManager
- tagging.py: Register PHIs with manager

### Documentation
**New Files**:
- docs/development/architecture/exit-phi-design.md
- docs/development/current/main/investigations/phase132-llvm-exit-phi-wrong-result.md
- docs/development/current/main/phases/phase-132/

**Updated**:
- docs/development/current/main/10-Now.md
- docs/development/current/main/phase131-3-llvm-lowering-inventory.md

### Design Principles
- Box-First: Logic encapsulated in classes/methods
- SSOT: Single Source of Truth (builder.vmap for PHIs)
- Fail-Fast: Early explicit failures, no fallbacks
- Separation of Concerns: 3-layer architecture

  - PHI-only フィルタを削除
  - 全ての値を global vmap に sync

変更ファイル:
- src/llvm_py/builders/block_lower.py: vmap sync 修正
- src/llvm_py/instructions/controlflow/branch.py: trace logging 追加
- src/llvm_py/instructions/unop.py: trace logging 追加
- src/llvm_py/llvm_builder.py: debug helpers 追加
- src/llvm_py/phi_wiring/wiring.py: trace logging 追加
- src/runner/modes/common_util/exec.rs: Python stdout 転送

結果:
- ✅ Branch bug 修正: ループが正しく終了
- ✅ 出力: 無限ループ → 3回で停止
- ❌ 新 bug 発見: ExternCall が null を受け取る（PHI 値の代わりに）

Next: Phase 131-8 (ExternCall argument handling 修正)

e4eedef34f feat(llvm): Phase 132 - Fix PHI instruction ordering bug 
Structural fix for LLVM backend PHI placement issue discovered in Phase 131.

Changes:
- Modified ensure_phi() to position PHI before existing instructions
- Enhanced setup_phi_placeholders() with debug mode
- Created phi_placement.py utility for validation
- Added test script for representative cases

Technical approach:
- PHI creation during setup (before block lowering)
- Explicit positioning with position_before(instrs[0])
- Debug infrastructure via NYASH_PHI_ORDERING_DEBUG=1

Design principles:
- PHI must be created when blocks are empty
- finalize_phis only wires, never creates
- llvmlite API constraints respected

Phase 132 complete. Ready for Phase 133 (ConsoleBox integration).

7b1f791395 feat(phase21.5): Loop FORCE direct assembly + PHI/compare fixes 
## Loop FORCE Direct Assembly ✅
- Added: Direct MIR assembly bypass when HAKO_MIR_BUILDER_LOOP_FORCE_JSONFRAG=1
- Implementation: Extracts limit from Program(JSON), generates minimal while-form
- Structure: entry(0) → loop(1) → body(2) → exit(3)
- PHI: i = {i0, entry} | {i_next, body}
- Location: tools/hakorune_emit_mir.sh:70-126
- Tag: [selfhost-direct:ok] Direct MIR assembly (FORCE=1)

## PHI/Compare Fixes (ny-llvmc) ✅
- Fixed: vmap maintenance for PHI results across instructions
- Fixed: PHI placeholder name consistency (bytes vs str)
- Fixed: ensure_phi_alloca creates unique placeholders per block
- Fixed: resolve_i64_strict properly looks up PHI results
- Files:
  - src/llvm_py/phi_wiring/tagging.py
  - src/llvm_py/phi_wiring/wiring.py
  - src/llvm_py/instructions/compare.py
  - src/llvm_py/resolver.py

## Testing Results
- VM backend: ✅ rc=10 (correct)
- Direct assembly MIR: ✅ Structurally correct
- Crate backend: ⚠️ PHI/compare issues (being investigated)

## Implementation Principles
- 既定挙動不変 (FORCE=1 gated)
- Dev toggle controlled
- Minimal diff, surgical changes
- Bypasses using resolution when FORCE=1
