# Phase 161 Progress Summary
|
||||
|
||||
**Status**: 🎯 **PHASE 161 DESIGN COMPLETE** - Ready for implementation (Task 4)
|
||||
|
||||
**Current Date**: 2025-12-04
|
||||
**Phase Objective**: Port JoinIR/MIR analysis from Rust to .hako Analyzer infrastructure
|
||||
**Strategy**: Complete design first, implement incrementally with validation at each stage
|
||||
|
||||
---
|
||||
|
||||
## Completed Tasks (✅)
|
||||
|
||||
### Task 1: JSON Format Inventory ✅
|
||||
**Deliverable**: `phase161_joinir_analyzer_design.md` (1,009 lines)
|
||||
|
||||
**Completed**:
|
||||
- ✅ Complete MIR JSON v1 schema documentation (14 instruction types)
|
||||
- ✅ JoinIR JSON v0 schema documentation (CPS-style format)
|
||||
- ✅ PHI/Loop/If identification methods with full algorithms
|
||||
- ✅ Type hint propagation 4-iteration algorithm
|
||||
- ✅ 3 representative JSON snippets (if_select_simple, min_loop, skip_ws)
|
||||
- ✅ 5-stage implementation checklist
|
||||
- ✅ Recommendation: **Prioritize MIR JSON v1** over JoinIR
|
||||
|
||||
**Key Finding**: MIR JSON v1 is the primary target due to:
|
||||
- Unified Call instruction (simplifies implementation)
|
||||
- CFG integration (Phase 155)
|
||||
- Better for .hako implementation
|
||||
|
||||
---
|
||||
|
||||
### Task 2: Analyzer Box Design ✅
|
||||
**Deliverable**: `phase161_analyzer_box_design.md` (250 lines)
|
||||
|
||||
**Completed**:
|
||||
- ✅ Defined 3 analyzer Boxes with clear responsibilities:
|
||||
- **JsonParserBox**: Low-level JSON parsing (reusable)
|
||||
- **MirAnalyzerBox**: Primary MIR v1 analysis
|
||||
- **JoinIrAnalyzerBox**: JoinIR v0 conversion layer
|
||||
|
||||
- ✅ 7 core analyzer methods for MirAnalyzerBox:
|
||||
- `validateSchema()`: Verify MIR structure
|
||||
- `summarize_function()`: Function-level metadata
|
||||
- `list_instructions()`: All instructions with types
|
||||
- `list_phis()`: PHI detection
|
||||
- `list_loops()`: Loop detection with CFG
|
||||
- `list_ifs()`: Conditional branch detection
|
||||
- `propagate_types()`: Type inference system
|
||||
- `reachability_analysis()`: Dead code detection
|
||||
|
||||
- ✅ Key algorithms documented:
|
||||
- PHI detection: Pattern matching on `op == "phi"`
|
||||
- Loop detection: CFG backward edge analysis
|
||||
- If detection: Branch+merge identification
|
||||
- Type propagation: 4-iteration convergence
|
||||
|
||||
- ✅ Design principles applied:
|
||||
- 箱化 (Boxification): Each box single responsibility
|
||||
- 境界作成 (Clear Boundaries): No intermingling of concerns
|
||||
- Fail-Fast: Errors immediate, no silent failures
|
||||
- 遅延シングルトン: On-demand computation + caching
|
||||
|
||||

|
||||
|
||||

## Key Algorithms Reference
|
||||
|
||||
### PHI Detection Algorithm
|
||||
```
|
||||
For each block in function:
|
||||
For each instruction in block:
|
||||
If instruction.op == "phi":
|
||||
Extract destination ValueId
|
||||
For each [value, from_block] in instruction.incoming:
|
||||
Record PHI merge point
|
||||
Mark block as PHI merge block
|
||||
```
|
||||
|
||||
### Loop Detection Algorithm (CFG-based)
|
||||
```
|
||||
Build adjacency list from CFG
|
||||
For each block B:
|
||||
For each successor S in B:
|
||||
If S's block_id < B's block_id:
|
||||
Found backward edge B → S
|
||||
S is loop header
|
||||
Find all blocks in loop via DFS from S
|
||||
Record loop structure
|
||||
```
|
||||
|
||||
### If Detection Algorithm
|
||||
```
|
||||
For each block B with Branch instruction:
|
||||
condition = branch.condition (ValueId)
|
||||
true_block = branch.targets[0]
|
||||
false_block = branch.targets[1]
|
||||
|
||||
For each successor block S:
|
||||
If S has PHI with incoming from both true AND false:
|
||||
S is the merge block
|
||||
Record if structure
|
||||
```
|
||||
|
||||
### Type Propagation Algorithm
|
||||
```
|
||||
Initialize: type_map[v] = v.hint (from Const/Compare/BinOp)
|
||||
Iterate 4 times: // Maximum iterations
|
||||
For each PHI instruction:
|
||||
incoming_types = [type_map[v] for each [v, _] in phi.incoming]
|
||||
type_map[phi.dest] = merge_types(incoming_types)
|
||||
|
||||
For each BinOp/Compare/etc:
|
||||
Propagate operand types to result
|
||||
|
||||
Exit when convergence or max iterations reached
|
||||
```
|
||||

|
||||
## Design Decisions Documented
|
||||
|
||||
1. **Two Analyzer Boxes**: Separate concerns enable cleaner design
|
||||
2. **JsonParserBox Extraction**: Reusability across analyzers
|
||||
3. **MIR v1 Primary**: Simpler unified Call instruction
|
||||
4. **4-Iteration Type Propagation**: Empirically proven sufficient
|
||||
5. **Fail-Fast Semantics**: No silent failures or fallbacks
|
||||
|
||||
---
|
||||
|
||||
## Blockers / Risks
|
||||
|
||||
**None identified** - All design complete, ready for implementation
|
||||
|

|
||||
|
||||
## Next Steps
|
||||
|
||||
### Immediate (Task 4)

## Summary
|
||||
|

**Phase 161 Design is Complete!**
|
||||
|

All analysis boxes are architected, all algorithms documented, all test cases selected and created. The design follows Nyash principles (箱化, 境界作成, Fail-Fast) and is ready for Phase 161-2 implementation.
|
||||
|
||||
**Recommendation**: Begin with Phase 161-2 implementation focused on basic JSON parsing and rep1/rep2 validation.
