Stage 3: Code Generator

This stage implements multi-target code generation (TypeScript and Rust) with self-compilation validation.

Overview

Stage 3 takes typed ASTs from Stage 2 and generates executable code in multiple target languages:

  • TypeScript code emission
  • Rust code emission
  • Self-compilation validation
  • Semantic preservation verification

Tickets

  • BOOTSTRAP-014: TypeScript Code Emitter
  • BOOTSTRAP-015: Rust Code Emitter
  • BOOTSTRAP-016: Self-Compilation Test

Success Criteria

✅ Valid TypeScript generated (passes tsc) ✅ Valid Rust generated (passes rustc) ✅ Self-compilation: compiler can compile itself ✅ Semantic preservation: behavior matches source ✅ >10K LOC/s throughput

Technical Highlights

  • Multi-target: Single compiler → multiple output languages
  • Idiomatic code: Generated code follows target language conventions
  • Type preservation: TypeScript/Rust types match inferred types
  • Bit-identical: Self-compilation produces identical output
