- Added LoopForm IR scaffolding with 5-block structure (header/body/dispatch/latch/exit)
- Implemented dispatch block with PHI nodes for tag(i8) and payload(i64)
- Created registry infrastructure for future body→dispatch wiring
- Header→dispatch wiring complete with Break=1 signal
- Gated behind NYASH_ENABLE_LOOPFORM=1 environment variable
- Successfully tested with loop_min_while.nyash (1120 bytes object)
Next steps:
- Implement 2-step Jump chain detection
- Add NYASH_LOOPFORM_BODY2DISPATCH for body→dispatch redirect
- Connect latch→header when safe
🚀 Phase 1 foundation complete and working!
