Phase 131-12: LLVM Wrong Result (Case C)
Status: ✅ Root cause identified Problem: LLVM backend returns wrong results for loop exit values Root Cause: vmap object identity mismatch between Pass A and Pass C
Key Documents:
- phase131-12-case-c-llvm-wrong-result.md - Initial investigation scope
- phase131-12-p1-vmap-identity-analysis.md - Detailed trace analysis
- phase131-12-p1-trace-summary.md - Executive summary with fix recommendations
Quick Summary:
- Bug: Pass A deletes
_current_vmapbefore Pass C runs - Impact: Terminators use wrong vmap object, missing all Pass A writes
- Fix: Store vmap_cur in deferred_terminators tuple (Option 3)
Next Steps:
- Implement Option 3 fix in block_lower.py
- Add Fail-Fast check in instruction_lower.py
- Verify with NYASH_LLVM_VMAP_TRACE=1
- Run full test suite
Trace Environment Variables
Phase 131-12-P1 Traces

Investigation Workflow
- Scope - Define problem and test case (phase131-12-case-c-*.md)
- Trace - Add instrumentation and collect data (phase131-12-p1-vmap-identity-*.md)
- Analysis - Identify root cause with evidence (phase131-12-p1-trace-summary.md)
- Fix - Implement solution with validation
- Document - Update investigation notes with results
