- Add function name prefix to basic block labels to avoid cross-function conflicts
- blocks.rs: create_basic_blocks now takes fn_label parameter
- Format: 'Main_join_2_bb23' instead of just 'bb23'
- Add conservative fallback for missing terminators (jump to next or entry)
- This fixes 'Basic Block does not have terminator' verification error
Analysis insights:
- MIR output was correct (all blocks had terminators)
- Problem was LLVM-side block name collision between functions
- Classic case of 'Rust complexity' - simple C++ style fix works best
- Sometimes the simplest solution is the right one\!
## LLVM Call Instruction Modularization
- Moved MirInstruction::Call lowering to separate instructions/call.rs
- Follows the principle of one MIR instruction per file
- Call implementation was already complete, just needed modularization
## Phase 21 Documentation
- Moved all Phase 21 content to private/papers/paper-f-self-parsing-db/
- Preserved AI evaluations from Gemini and Codex
- Academic paper potential confirmed by both AIs
- Self-parsing AST database approach validated
## Next Steps
- Continue monitoring ChatGPT5's LLVM improvements
- Consider creating separate nyash-llvm-compiler crate when LLVM layer is stable
- This will reduce build times by isolating LLVM dependencies

Major improvements to LLVM backend function call infrastructure:
## Key Changes
### Function Call System Complete
- All MIR functions now properly lowered to LLVM (not just entry)
- Function parameter binding to LLVM arguments implemented
- ny_main() wrapper added for proper entry point handling
- Callee resolution from ValueId to function symbols working
### Call Instruction Analysis
- MirInstruction::Call was implemented but system was incomplete
- Fixed "rhs missing" errors caused by undefined Call return values
- Function calls now properly return values through the system
### Code Modularization (Ongoing)
- BoxCall → instructions/boxcall.rs ✓
- ExternCall → instructions/externcall.rs ✓
- Call remains in mod.rs (to be refactored)
### Phase 21 Documentation
- Added comprehensive AI evaluation from Gemini and Codex
- Both AIs confirm academic paper potential for self-parsing AST DB approach
- "Code as Database" concept validated as novel contribution

Implemented elegant solution for MapBox as core box with plugin fallback:
1. Core-first Strategy:
- Removed MapBox type_id from nyash_box.toml
- MapBox now uses env.box.new fallback (core implementation)
- Consistent with self-hosting goals
2. Plugin Fallback Option:
- Added NYASH_LLVM_FORCE_PLUGIN_MAP=1 environment variable
- Allows forcing MapBox to plugin path when needed
- Preserves flexibility during transition
3. MIR Type Inference:
- Added MapBox method type inference (size/has/get)
- Ensures proper return type handling
4. Documentation:
- Added core vs plugin box explanation in nyrt
- Clarified the transition strategy
This aligns with Phase 15 goals where basic boxes will eventually
be implemented in Nyash itself for true self-hosting.

Major enhancements to LLVM code generation and type handling:
1. String Operations:
- Added StringBox length fast-path (length/len methods)
- Converts i8* to handle when needed for len_h call
- Consistent handle-based string operations
2. Array/Map Fast-paths:
- ArrayBox: get/set/push/length operations
- MapBox: get/set/has/size with handle-based keys
- Optimized paths for common collection operations
3. Field Access:
- getField/setField implementation with handle conversion
- Proper i64 handle to pointer conversions
4. NewBox Improvements:
- StringBox/IntegerBox pass-through optimizations
- Fallback to env.box.new when type_id unavailable
- Support for dynamic box creation
5. Documentation:
- Added ARCHITECTURE.md for overall design
- Added EXTERNCALL.md for external call specs
- Added LOWERING_LLVM.md for LLVM lowering rules
- Added PLUGIN_ABI.md for plugin interface
6. Type System:
- Added UserBox type registration in nyash_box.toml
- Consistent handle (i64) representation across system
Results: More robust LLVM code generation with proper type handling

Documented the architectural decision for Nyash runtime design:
1. Core boxes (String/Integer/Array/Map/Bool) built into nyrt
- Essential for self-hosting
- Available at boot without plugin loader
- High performance (no FFI overhead)
2. All other boxes as plugins (File/Net/User-defined)
- Extensible ecosystem
- Clear separation of concerns
3. Minimal ExternCall (only 5 functions)
- print/error (output)
- panic/exit (process control)
- now (time)
Key principle: Everything goes through BoxCall interface
- No special fast paths
- Unified architecture
- "Everything is Box" philosophy maintained
This design balances self-hosting requirements with architectural purity.

Major changes:
- Removed 617 lines of duplicate/legacy code from mod.rs (lines 351-967)
- All BoxCall handling now properly delegated to instructions::lower_boxcall
- Updated CURRENT_TASK.md with new findings:
- String concatenation issue (BinOp type mismatch)
- Plugin return value smoke test added
- Clear next steps for fixing return value display
Key improvements:
- Clean separation between dispatch (mod.rs) and implementation (instructions.rs)
- Legacy code marked as unreachable and ready for removal
- Better error visibility with modularized code structure
- llvm_smoke.sh updated with new plugin return value tests
Next steps:
1. Fix BinOp string concatenation type handling
2. Investigate MIR value_types for BoxCall returns
3. Further split lower_boxcall function (still 260+ lines)
- BoxCall handling now properly delegated to instructions::lower_boxcall
- Removed duplicate code in mod.rs (lines 351+ were unreachable after continue)
- Clean separation between dispatch (mod.rs) and implementation (instructions.rs)
- Preparing for further BoxCall function breakdown
Work in progress - ChatGPT continuing refactoring efforts
- Split 2522-line codegen.rs into modular structure:
- mod.rs (1330 lines) - main compilation flow and instruction dispatch
- instructions.rs (1266 lines) - all MIR instruction implementations
- types.rs (189 lines) - type conversion and classification helpers
- helpers.rs retained for shared utilities
- Preserved all functionality including:
- Plugin return value handling (BoxCall/ExternCall)
- Handle-to-pointer conversions for proper value display
- Type-aware return value processing based on MIR metadata
- All optimization paths (ArrayBox fast-paths, string concat, etc.)
- Benefits:
- Better code organization and maintainability
- Easier to locate specific functionality
- Reduced cognitive load when working on specific features
- Cleaner separation of concerns
No functional changes - pure refactoring to improve code structure.
