Selfhosting Dev 89e6fbf010 feat(llvm): Comprehensive LLVM backend improvements by ChatGPT

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

Raw Blame History

Nyash Project – Changelog (Work in progress)

This changelog tracks high‑level milestones while Core MIR and Phase 12 evolve. For detailed per‑file history, see git log and docs under docs/development/roadmap/.

2025‑09‑06

Core‑13 flip complete: code/tests enforce Core‑13 minimal kernel. Normalizations (Array/Ref→BoxCall, TypeCheck/Cast/Barrier/WeakRef unification) are ON by default via env (NYASH_MIR_CORE13=1). New tests validate normalization.
Docs synced: step‑50 marked done; DEV quickstart points to Core‑13 reference.

2025‑09‑04

Phase 12.7‑A complete: peek, continue, ? operator, lambda, field type annotations. Language reference updated.
Phase 12.7‑B (basic) complete: parser‑level desugaring for |>, ?., ??, +=/-=/*=/=, .. behind NYASH_SYNTAX_SUGAR_LEVEL.
Docs: language reference and Phase 12.7 README updated to reflect basic completion; extensions tracked under gated plan.
MIR Core migration: previously enforcing Core‑15 during transition; superseded by 2025‑09‑06 Core‑13 flip.

2025‑09‑03

Nyash ABI TypeBox integration stabilized across core boxes; differential tests added; loader defaults adjusted (builtin + plugins).

Notes

Core‑13 is canonical minimal kernel. Historical Core‑15 notes remain under docs/development/roadmap/ for reference.
Phase 12.7‑B desugaring is gated by NYASH_SYNTAX_SUGAR_LEVEL; tokenizer additions are non‑breaking.

2025‑09‑11 (Phase 15)

llvm: BoxCall arm cleanup — unreachable legacy block removed; arm now delegates solely to instructions::lower_boxcall.
llvm/docs: Documented LLVM lowering rules (StringBox i8* fast path, ExternCall ptr/handle selection, minimal fallback policy for string concat).
docs: Added ARCHITECTURE.md, LOWERING_LLVM.md, EXTERNCALL.md, PLUGIN_ABI.md.
nyrt: resolved plugin module duplication; build green.
builder: suppressed StringBox birth (constructed in LLVM path).
