Scope

This project was not only about implementing a compiler. It also had to be repeatedly validated and delivered for offline use. The path covered SysY input, LLVM and RISC-V backends, compile-only checks, and multi-backend regression.

What I built

I organized roughly 133KB of core implementation, wrote PowerShell regression scripts, and prepared repeatable checks for multiple backends. A React, TypeScript, and Vite practice site added offline delivery and troubleshooting guidance.

Result

The final package connected source, regression tests, a practice interface, and diagnostic documentation. It optimized for continuing to work after code changes and environment changes, not just for a one-time demo.
