- Added llvmlite verification harness strategy
- Python as parallel verification path for PHI/SSA issues
- Nyash ABI wrapper for LLVM emit abstraction
- NYASH_LLVM_USE_HARNESS=1 flag for mode switching
- Goal: Rust implementation in 1-2 days, Python for rapid verification
Acknowledging reality: When stuck at minimal viable implementation,
changing implementation language is a practical solution.
'Simple is Best' - the core Nyash philosophy.
ChatGPT5's investigation revealed builder position management issues:
- Added verbose logging for block lowering and terminator emission
- Enhanced position_at_end calls before all terminator operations
- Added debug output for emit_jump/emit_branch operations
- Improved snapshot vs vmap fallback reporting in seal_block
Key findings:
- Sealed SSA snapshot mechanism is working correctly
- Block terminator issues persist due to builder position drift
- Main.has_in_stack/2 shows terminator missing after emit
Next steps:
- Add immediate terminator verification after each emit
- Track builder position changes in complex operations
- Investigate specific functions where builder drift occurs
This commit adds diagnostic infrastructure to pinpoint
where LLVM IR builder position gets misaligned.
ChatGPT5 struggling for 34+ minutes with Rust lifetime/build errors...
This perfectly illustrates why we need Phase 22 (Nyash LLVM compiler)\!
Key insights:
- 'Rust is safe and beautiful' - Gemini (who never fought lifetime errors)
- Reality: 500-line error messages, 34min debug sessions, lifetime hell
- C would just work: void* compile(void* mir) { done; }
- Python would work: 100 lines with llvmlite
- ANY language with C ABI would work\!
The frustration is real:
- We're SO CLOSE to Nyash self-hosting paradise
- Once bootstrapped, EVERYTHING can be written in Nyash
- No more Rust complexity, no more 5-7min builds
- Just simple, beautiful Box-based code
Current status:
- PHI/SSA hardening in progress (ChatGPT5)
- 'phi incoming value missing' in Main.esc_json/1
- Sealed SSA approach being implemented
The dream is near: Everything is Box, even the compiler\! 🌟
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
